Kidney Health Questions

Early kidney disease is silent — no symptoms until 60-70% of function is lost. That's why blood tests (creatinine, eGFR) and urine tests (for protein) matter. Later signs: swelling in feet or around eyes, foamy urine, changes in urination frequency, fatigue, itchy skin, poor appetite, or high BP that's hard to control. If you have diabetes or hypertension, annual kidney checks are essential.

Long-term high blood sugar damages the tiny filters in the kidneys. Over years, this leads to protein leaking into urine, then falling kidney function, and in some cases eventual dialysis or transplant. The good news: tight blood sugar control, BP control, and specific medications (ACE inhibitors, ARBs, SGLT2 inhibitors) dramatically slow this. Annual urine microalbumin test catches early damage when it's still reversible.

Yes — persistent protein in urine (proteinuria or albuminuria) is one of the earliest signs of kidney damage, especially in diabetes and hypertension. A single positive result should be repeated to confirm. If confirmed, treatment usually includes a specific class of BP medications that also protect kidneys, even if BP isn't very high. Don't ignore it.

For healthy kidneys, no specific food is harmful in normal amounts. For someone with reduced kidney function, doctors often advise limiting salt, potassium (in some cases), phosphorus, and protein — but the specifics depend on your kidney stage. Over-the-counter painkillers (especially NSAIDs like ibuprofen and diclofenac) can harm kidneys, particularly with regular use — safer to check with your doctor before frequent use.

Early damage — the leaking of small amounts of protein — can often be reversed or halted with good BP and sugar control. Once significant scarring has happened (chronic kidney disease stage 3-5), the goal shifts to slowing progression rather than reversing damage. This is why early screening in diabetes and hypertension matters so much.

The best fruits for diabetics are low-glycemic, high-fibre options like berries, apples, and citrus fruits. Berries: Strawberries, blueberries, and blackberries are very low in sugar and high in fibre and antioxidants. Apples and Pears: Eat them with the skin on for maximum fibre, which slows sugar absorption. Citrus Fruits: Oranges, grapefruits, and clementines provide vitamin C and soluble fibre.Stone Fruits: Peaches, plums, and apricots have a low glycemic impact when eaten in moderation.Guava:

Chronic disease management covers long-term health conditions that last for one year or longer and require ongoing medical care.

Sustained clinical remission is achievable for a meaningful proportion of RA patients on well-managed treatment, particularly those who start DMARDs early. Remission means low disease activity, minimal symptoms, and no new joint damage on imaging, not that the disease is gone. Stopping medication after remission is a difficult decision made carefully with a rheumatologist: some patients can taper to lower doses successfully; others relapse quickly. The risk of relapse is highest in the first year off medication, and relapse often means more aggressive disease. The general rule is that RA is a lifelong condition needing lifelong management, but the intensity of that management can be much lower during remission. Biologic DMARDs, which cost significantly more than conventional DMARDs, have improved the proportion of patients achieving durable remission, increasingly covered by Indian mediclaim policies for eligible patients.

Any joint symptoms lasting more than 6 weeks warrant rheumatology referral, particularly if you have symmetric small-joint swelling (both hands, both wrists), morning stiffness longer than 30 minutes, fatigue and low-grade fever alongside joint symptoms, a family history of RA or other autoimmune diseases, or new joint symptoms in someone under 50. A family physician can start initial blood tests (RF, anti-CCP, ESR, CRP) and paracetamol for symptom relief, but definitive RA treatment requires DMARDs which should be prescribed and monitored by a rheumatologist. In Indian tier-1 cities, rheumatology consults are widely available; in smaller cities, orthopaedists with rheumatology interest often serve this role. The 6-12 month window from symptom onset is the highest-benefit period for starting DMARDs, delaying diagnosis means preventable joint damage.

Yes, meaningfully. Genetic risk sets the probability but does not determine the trajectory. Three lifestyle changes have the strongest evidence for reducing RA progression: (a) quitting smoking, smoking accelerates RA progression more than almost any other modifiable factor and reduces DMARD effectiveness; (b) maintaining healthy weight, excess weight increases inflammatory markers and mechanically loads inflamed joints; (c) regular low-impact exercise like swimming, cycling, or yoga, reduces joint stiffness and preserves muscle strength around inflamed joints. Anti-inflammatory diet (Mediterranean-style, rich in omega-3s and vegetables, low in refined carbohydrates) has modest evidence for symptom improvement. None of these replace medical treatment with DMARDs, but combined with proper medication, they measurably slow long-term joint damage.

The two are commonly confused but behave very differently. RA is an autoimmune disease where the body's immune system attacks joint linings, typically causing symmetric small-joint swelling (both hands, both feet) with morning stiffness lasting more than 30 minutes and often systemic symptoms like fatigue or low-grade fever. It can start at any age. Osteoarthritis is mechanical wear-and-tear on joint cartilage, typically affects large weight-bearing joints (knees, hips) asymmetrically, and morning stiffness is brief (under 30 minutes). It usually starts after 50. A rheumatologist confirms RA through blood tests (RF, anti-CCP, ESR, CRP) and joint imaging. If you have symmetric hand-joint swelling with prolonged morning stiffness, do not assume osteoarthritis, this is often RA and treatment is very different.

Common autoimmune blood tests widely available in Indian labs: ANA (antinuclear antibody), a general screening test; RF (rheumatoid factor) and anti-CCP, for rheumatoid arthritis; anti-dsDNA and anti-Smith, more specific for lupus; TSH plus anti-TPO and anti-thyroglobulin, for autoimmune thyroid disease (Hashimoto's, Graves'); tissue transglutaminase (tTG), for celiac disease; ESR and CRP, general inflammation markers, non-specific but useful for tracking disease activity. Ask for autoimmune screening if you have: persistent joint pain lasting more than 6 weeks, unexplained fatigue lasting weeks, unexplained skin rashes especially with sun sensitivity, thyroid symptoms (weight change, temperature intolerance, fatigue), or family history of autoimmune disease plus any suggestive symptoms. Results always need interpretation by a doctor, many people have low-positive ANA without any autoimmune disease, and the pattern of positives (which specific antibodies) matters more than any single test.

Two main mechanisms explain the infection-autoimmune link. First, molecular mimicry: some pathogens produce proteins that structurally resemble the body's own proteins. When the immune system attacks the pathogen, it can accidentally attack similar-looking self-proteins, a well-documented example is rheumatic fever after streptococcal throat infection, where anti-strep antibodies cross-react with heart valve tissue. Second, tissue damage from infection can expose 'hidden' self-antigens (proteins normally shielded from immune surveillance) to immune cells, triggering an autoimmune response. Well-studied examples: viral infections triggering type 1 diabetes onset in genetically susceptible children, Epstein-Barr virus infection increasing multiple sclerosis risk, and various infections triggering lupus flares. This does not mean infections cause autoimmune disease in most people, genetic susceptibility must be present, but they are common triggering events in people already at risk.

Most autoimmune diseases cannot be cured currently but can be managed effectively, often to the point of clinical remission with minimal symptoms. Modern treatment falls into three categories: (a) immunosuppressive medications that dampen the overactive immune response (steroids for acute flares, methotrexate and other DMARDs for long-term control); (b) biologic drugs that target specific parts of the immune response (adalimumab, rituximab, tocilizumab for RA and lupus; interferons for MS); (c) replacement therapy for damaged tissues (insulin for type 1 diabetes, thyroxine for Hashimoto's, vitamin D for related deficiencies). Sustained remission is now achievable for many patients with early aggressive treatment, particularly RA and inflammatory bowel disease. Lifestyle factors, quitting smoking, stress management, adequate sleep, anti-inflammatory diet, meaningfully improve outcomes alongside medication. Ongoing research into immune-tolerance therapies aims for actual cure but is not yet standard practice.

Having a first-degree relative with an autoimmune disease increases your risk roughly 3-5 times over the general population for the same disease, and modestly increases risk for other autoimmune diseases too, because many share genetic markers in the HLA (major histocompatibility complex) region. But most people with family history never develop an autoimmune disease, and most autoimmune-disease patients have no clear family history. Practical implications: family history is a risk multiplier, not a diagnosis. If you have a first-degree relative with RA, lupus, type 1 diabetes, MS, celiac disease, or autoimmune thyroid disease, be alert for symptoms in yourself, persistent joint pain, unexplained fatigue, thyroid changes, unexplained rashes, and get autoimmune blood-panel testing at first symptoms rather than assuming stress. Female sex is a stronger risk factor than family history for many autoimmune diseases; women account for roughly 80% of autoimmune disease cases.

Blunt answer: NO. There is no legitimate 30-day cure for any autoimmune disease. Current medical science can achieve REMISSION (no active symptoms, normal blood markers) in many autoimmune conditions with proper medications, but this is symptom control — the underlying immune dysregulation persists and typically requires lifelong management. Diseases like rheumatoid arthritis, lupus (SLE), multiple sclerosis, type 1 diabetes, Hashimoto’s thyroiditis, Crohn’s disease, and psoriasis can all be well-controlled but not cured. Modern DMARDs (methotrexate) and biologics (adalimumab, rituximab, tocilizumab) can achieve remission in 40-60% of RA patients within 6-12 months when started early. What 'cure in 30 days' marketing usually means: fraudulent claims for financial gain (expensive treatment packages that don't work); temporary symptom masking, often with hidden steroids in unregulated Ayurvedic or homeopathic preparations (documented in medical literature); or coincidental disease remission that would have happened anyway. Legitimate treatments never make ‘30 days’ claims.

Autoimmune diseases arise from a combination of genetic susceptibility (30-50% of risk) and environmental triggers (50-70% of risk). You cannot change your genes, but you can modify environmental factors that trigger autoimmune activation: (1) Vitamin D adequacy — Indian population 70-80% deficient (NIN-ICMR data); adequate Vitamin D reduces risk of MS, T1DM, RA in observational studies; target 25-OH-D level 30-50 ng/mL through sun exposure + supplementation (2000-4000 IU/day); (2) Smoking cessation — smoking directly triggers RA in genetically susceptible individuals; smoking cessation reduces RA risk 30-50% over 20 years; (3) Gut health — probiotic-rich foods (dahi, kimchi, kefir), fibre-rich diet, avoid unnecessary antibiotics; disrupted gut microbiome linked to IBD, RA, T1DM; (4) Weight management — obesity worsens autoimmune outcomes; (5) EBV/mono infection — avoid in adolescence if possible (unrealistic but linked to MS, lupus); (6) Stress management — chronic severe stress may trigger flares; (7) Early treatment of triggering infections. Once autoimmune disease is established, focus shifts to preventing progression and maintaining remission through medications + lifestyle. Family history doesn’t guarantee disease — most people with genetic susceptibility never develop autoimmune illness.

Common autoimmune conditions in India, ranked by prevalence: (1) Hashimoto’s thyroiditis (autoimmune hypothyroidism) — affects 8-15% of Indian women; anti-TPO antibody positive; treated with lifelong levothyroxine; (2) Rheumatoid arthritis — 0.5-1% of Indian adults; anti-CCP positive; requires DMARD therapy; (3) Type 1 diabetes — increasing in Indian children; autoimmune beta-cell destruction; insulin-dependent; (4) Psoriasis — 0.5-1% of Indians; genetic + environmental triggers; topical + systemic therapies; (5) Systemic Lupus Erythematosus (SLE) — 3-5x more common in women, especially 15-45 years; requires hydroxychloroquine ± immunosuppressants; (6) Vitiligo — 0.5-2% of Indians; melanocyte destruction; cosmetic and psychological impact; (7) Ankylosing spondylitis — young men predominantly; HLA-B27 positive in 90%; (8) Inflammatory bowel disease (Crohn’s + ulcerative colitis) — rising in India; requires GI specialist care; (9) Sjogren’s syndrome; (10) Multiple sclerosis (less common in India than West). Family clustering common — if first-degree relative has autoimmune disease, your risk of any autoimmune disease is 3-5x higher.

No — RA is an autoimmune disease, not a lifestyle disease; medications are essential to prevent joint destruction. Lifestyle changes support treatment but do NOT replace it. Evidence-supported adjuncts: (1) Mediterranean-style diet — olive oil, nuts, fish, whole grains, vegetables; reduces inflammation modestly; Indian version: use mustard/olive oil, add fatty fish (salmon, sardines, mackerel) 2x/week, walnuts and flaxseeds for omega-3, ample seasonal vegetables and dals; (2) Vitamin D optimisation — 70-80% of Indians deficient; RA outcomes worse with low vitamin D; supplement to 25-OH-D level 30-50 ng/mL; (3) Weight management — obesity worsens RA outcomes; (4) Regular low-impact exercise — walking, swimming, cycling, tai chi; reduces morning stiffness and improves joint mobility; (5) Smoking cessation — critical; smoking directly worsens RA activity and reduces medication response by 30-40%; (6) Stress management — chronic stress correlates with disease flares. Turmeric (curcumin 500mg + piperine 5mg twice daily) has anti-inflammatory effect but should NOT replace DMARDs; can be added as adjunct. Beware of ‘miracle cures’ promising RA cure through diet alone — these delay proper treatment and cause irreversible joint damage.

Treatment goal: achieve 'remission' (no active joint swelling, no morning stiffness, normal blood markers) as fast as possible — a 'treat-to-target' strategy. Standard ladder: first-line DMARD is methotrexate 15-25 mg once weekly with daily folic acid; response in 6-12 weeks; needs monthly LFT and CBC monitoring for first 3 months then quarterly. Second-line: add hydroxychloroquine and sulfasalazine ('triple therapy'). Third-line for moderate-to-severe unresponsive cases: biologics — TNF inhibitors (adalimumab, etanercept), IL-6 blocker (tocilizumab), or JAK inhibitors (tofacitinib); Indian biosimilars are significantly more affordable than branded imports, and some biologics are available under Ayushman Bharat for eligible patients. Steroids (prednisolone 5-10 mg daily) are used as bridge therapy while waiting for DMARD to work — short-term only, because long-term steroids cause diabetes, osteoporosis, and cataracts. Physiotherapy and occupational therapy run throughout. Methotrexate plus hydroxychloroquine controls disease adequately in most patients when started early; biologics are needed in about 15-25% of cases. Never stop DMARD abruptly — always titrate under rheumatologist supervision.

Diagnosis requires clinical assessment plus blood tests plus imaging. Essential blood tests: Anti-CCP antibody is the most specific test for RA (95% specificity), positive in 60-70% of cases. Rheumatoid Factor (RF) is less specific but confirmatory. ESR and CRP measure inflammation. CBC often shows anaemia of chronic disease. LFT and KFT are needed as baseline before methotrexate. Uric acid rules out gout mimicking RA. Imaging: X-rays of hands and feet for baseline erosion documentation; ultrasound of affected joints detects early synovitis before X-ray changes; MRI is used in complex cases. Diagnostic classification uses ACR-EULAR 2010 criteria — needs 6+ points from joint distribution, serology, inflammation markers, and duration. See a rheumatologist (not just a general orthopedic surgeon) for RA — the Indian Rheumatology Association maintains a directory at indianrheumatology.org.

Stage 1 (early/pre-clinical): immune system starts attacking synovial tissue lining joints; may have mild joint tenderness, morning stiffness, fatigue; X-rays normal; often only detected by blood tests (anti-CCP, RF positive); this is the CRITICAL window for treatment. Stage 2 (moderate): inflammation causes synovium thickening (synovitis); joints become visibly swollen, warm, tender; multiple small joints affected symmetrically — MCP (knuckle), PIP (finger middle joint), wrist, ankle joints most typical; morning stiffness lasts more than 1 hour; anti-CCP + RF strongly positive. Stage 3 (severe): cartilage begins to erode, bone starts eroding at joint margins (visible on X-ray as periarticular erosions); joint space narrowing; loss of mobility; noticeable ‘ulnar deviation’ (fingers drifting toward little finger side), swan-neck or boutonniere deformities appear; functional disability accelerates. Stage 4 (end-stage): joints fuse or collapse; permanent deformities; severe disability; joint replacement often needed. Modern RA treatment aims to catch and control disease at Stage 1-2 so patients never reach Stage 3-4 — this is achievable with early DMARD (methotrexate) initiation.

The immune system’s job is to identify and destroy threats (bacteria, viruses, cancer cells) while leaving your own tissues alone. This distinction is made through ‘self vs non-self’ recognition — trained during immune-cell development in the thymus and bone marrow. In autoimmune disease, this recognition breaks down: T-cells and B-cells that should have been eliminated during development escape into circulation and start attacking body tissues as if they were foreign. Specific mechanisms: (1) Molecular mimicry — a foreign antigen (from infection) closely resembles a self-antigen, causing cross-reactive attack; (2) Genetic predisposition — certain HLA gene variants (HLA-B27 in ankylosing spondylitis, HLA-DR4 in RA, HLA-DR3 in T1DM) make immune misrecognition more likely; (3) Environmental triggers — infections (Epstein-Barr virus linked to lupus, MS), smoking (worsens RA), UV light (triggers lupus flares), gut microbiome disruption (may drive IBD, RA); (4) Loss of regulatory T-cells (‘Tregs’) — normally keep autoreactive cells in check; when they fail, autoimmunity emerges. Once triggered, autoreactive B-cells produce autoantibodies (anti-CCP in RA, anti-dsDNA in lupus, anti-TPO in Hashimoto’s) that mark self-tissue for immune destruction, causing chronic inflammation and damage.

Red flags of scam treatments: guarantee of cure in a specific timeframe (30 days, 60 days, 3 months); 'doctors don't want you to know' or anti-modern-medicine marketing; extraordinary cost for undefined treatments; testimonials rather than published research; practitioners without verifiable medical credentials (not registered with CCIM, MCI, or state medical councils); refusal to work alongside your rheumatologist or specialist; recommends stopping ALL current medications — extremely dangerous with RA, lupus, IBD, or Type 1 diabetes. Common scams to avoid: unregulated 'Ayurvedic' preparations with hidden steroids (documented in medical literature — patients develop Cushing's syndrome and adrenal suppression); 'panchakarma cure' packages at unlicensed centres; homeopathy claiming to replace DMARDs; MLM 'nutritional supplement' pyramids marketed for autoimmune conditions. Protect yourself: verify practitioner registration (MCI/NMC for allopathy at nmc.org.in, CCIM for Ayurveda at ayushnext.ayush.gov.in, homeopathy councils); get published research references, not testimonials; never stop specialist-prescribed medications without their input; report suspected fraud to Consumer Affairs Ministry or the Medical Council. Real autoimmune care is boring: consistent medications, monitoring, and lifestyle basics.

Evidence-based treatments for common autoimmune diseases: Rheumatoid Arthritis — methotrexate, sulfasalazine, hydroxychloroquine, and biologics (tocilizumab, adalimumab); rheumatologist supervision essential. Systemic Lupus Erythematosus (SLE) — hydroxychloroquine (cornerstone), immunosuppressants (azathioprine, mycophenolate), belimumab for severe disease. Multiple Sclerosis — disease-modifying therapies (interferon beta, glatiramer, natalizumab, ocrelizumab). Type 1 Diabetes — insulin therapy, continuous glucose monitoring, education. Hashimoto's Thyroiditis — levothyroxine replacement. Crohn's Disease and Ulcerative Colitis — mesalamine, steroids, immunomodulators, biologics (infliximab, adalimumab). Adjunctive lifestyle changes with evidence: anti-inflammatory diet, adequate Vitamin D (target 30-50 ng/mL), regular moderate exercise, stress management, smoking cessation, quality sleep. These support treatment but do NOT replace medications. All autoimmune treatments require specialist supervision — see a rheumatologist, endocrinologist, neurologist, or gastroenterologist as appropriate.

Yes, in most cases. The Indian Diabetes Prevention Programme (IDPP) showed that lifestyle changes — mainly diet plus 30 minutes of daily walking — cut progression to Type 2 diabetes by 28% over 3 years. Losing 5–7% of body weight is the single most effective step; specific food choices amplify the effect.

White rice (limit to 1 katori per meal), maida-based items (naan, biscuits, pav), sugary tea/coffee, sweets, fruit juices, sabudana, and jaggery. High-carb snacks like samosa, pakora, and namkeen cause rapid sugar spikes. Not banned — but portioned and infrequent.

Roughly 1 katori of cooked rice OR 2 medium rotis per meal, paired with dal, sabzi, and salad to slow absorption. Swap white rice for hand-pounded, brown, or millet rice when possible. Roti made from jowar, bajra, or mixed-grain atta stabilises blood sugar better than pure wheat.

Every 6 months if HbA1c is between 5.7–6.4%. If it starts trending down with diet, extend to yearly. If it climbs above 6.5% on two tests, you have Type 2 diabetes and need to talk to a doctor about starting metformin alongside continued lifestyle changes.

Pressure, tightness, or a squeezing feeling in the centre of the chest — often described as an elephant sitting on the chest. It can spread to the left arm, jaw, or back. Unlike gas or muscle pain, it usually doesn't ease with movement or antacids. Call an ambulance if it lasts more than 10 minutes.

Yes. Women often present with fatigue, nausea, jaw or upper-back pain, and shortness of breath — without the classic chest pain. Indian women in particular under-report cardiac symptoms, and heart attacks are frequently missed as 'gastric' or 'acidity'. Any new unexplained fatigue or breathlessness deserves an ECG.

Not always — kidney disease, venous problems, and long sitting can also cause it. But bilateral swelling (both legs) that gets worse through the day and improves overnight, especially with breathlessness on lying flat, points to heart failure. See a doctor within a week; it needs an echocardiogram.

Occasional flutters after coffee, stress, or exertion are usually harmless. See a doctor if palpitations last more than a few minutes, come with chest pain, dizziness, or breathlessness, or happen at rest. A resting ECG plus a 24-hour Holter monitor can catch arrhythmias like AFib that raise stroke risk.

Yes, fruits like apples, berries, and kiwi are generally safe in moderate amounts. Avoid high-potassium fruits if advised.

Eggs, chicken, fish, and tofu are good options. Adjust quantities based on your kidney function.

Fluid needs vary. Some patients must limit fluids to prevent overload, while others may need normal hydration. Always follow medical advice.

Yes! Personalized nutrition plans cater to your lab results and health goals.

It's called uremic pruritus. When kidneys can't filter waste properly, toxins build up in the blood and irritate skin nerves. High phosphorus levels and dry skin make it worse. It's most common in Stage 4–5 CKD and dialysis patients — early-stage kidney disease rarely causes itching.

Start with rich fragrance-free moisturisers applied within 3 minutes of bathing, plus phosphorus control (limit dairy, dal, nuts). If severe, doctors prescribe gabapentin, difelikefalin (an approved uremic pruritus drug), or UVB light therapy. Antihistamines usually don't help — this isn't an allergic itch.

Body temperature rises at night, and there are no distractions from the sensation. Cool the bedroom to 22°C, take a lukewarm shower before bed (not hot — that worsens it), and moisturise legs and back where itching is most common.

Sometimes. Better dialysis clearance reduces toxin buildup and can improve itching in weeks. But 40–50% of dialysis patients still itch — because dialysis doesn't remove all pruritus-causing molecules. Report persistent itching so your dose or dialyser can be adjusted.

Small stones (under 5 mm) may pass with homeopathy plus high fluid intake — but the water is doing most of the work. Larger stones (above 6 mm) usually need shock-wave lithotripsy or surgery. Homeopathy can help with pain and preventing recurrence, not with dissolving big stones.

Berberis vulgaris is the most commonly prescribed for left-sided kidney stone pain that radiates to the groin. Cantharis is used for burning urination. Lycopodium suits right-sided pain with gas and bloating. A homeopath will pick based on your exact symptom pattern — self-prescribing rarely works well.

Immediately if you have fever with kidney pain, blood in urine, inability to pass urine, or severe pain that doesn't ease in 24 hours. These can signal obstruction or infection — both need conventional care within hours, not days.

At least 2.5–3 litres a day, spread across the day. Your urine should look pale yellow. This is the single most effective step for preventing stone recurrence — no homeopathic remedy substitutes for hydration.

Punarnava (Boerhavia diffusa) is the most well-known — it acts as a natural diuretic that helps flush small stones. Gokshura (Tribulus terrestris) is added for urinary tract soothing, and Varun (Crataeva nurvala) is used for stone dissolution. An Ayurvedic practitioner combines these based on your dosha and stone type.

Small stones (under 6 mm) may pass in 2–6 weeks with herbs plus 3+ litres of daily water. Larger stones may need 2–3 months of treatment — or referral to a urologist if they don't move. Track pain and any blood in urine; escalate to modern care if either worsens.

Spinach, beetroot, and chocolate (high oxalate), red meat and organ meats (high uric acid), and excess salt. Ayurveda also recommends avoiding cold drinks and heavy fried food. Emphasise coconut water, barley water, and kulthi dal (horse gram) — traditionally used for stone prevention.

Fever with flank pain, inability to pass urine, or severe pain lasting more than 24 hours — these suggest blockage or infection and need urgent hospital care. Also see a urologist if a stone above 8 mm hasn't moved after 6 weeks; it likely needs shock-wave lithotripsy.

Under 35 IU/mL is normal in most Indian labs. Slightly elevated (35–100) may need a repeat test. Above 100 IU/mL strongly suggests autoimmune thyroid disease (Hashimoto's or Graves'), especially if TSH is also abnormal. Some healthy people have mildly positive anti-TPO without disease.
