Fatigue for 2 years. B12 was rock bottom and ferritin was 9. Fixed in 8 weeks.
Chronic fatigue in Indian adults almost always traces to thyroid, iron, B12, or vitamin D — tested against calibrated ranges, not American cut-offs. Your endocrinologist reads the panel and writes the protocol within a week.
Every panel includes a 15–20 minute video consult with a specialist — read against South Asian-calibrated ranges. The AI works invisibly. The doctor does the medicine.
You tell your doctor you're exhausted. They check a basic CBC. "Everything's normal," they say. So you leave tired—still undiagnosed.
These biomarkers reveal the root causes — and what actually works to fix them.
Three steps. Your data. Your physician. Your protocol.
100+ biomarkers drawn at your door in 10 minutes. NABL-accredited labs. Results in 5 days. No clinic visit, no waiting rooms — just data.
Your physician reviews thyroid, iron, B12, cortisol, and metabolic markers. The actual cause of your exhaustion — identified and explained.
Root-cause treatment — thyroid medication, iron infusion, B12 shots, cortisol management — whatever your bloodwork demands. Delivered in 48h.
Root causes
Chronic fatigue has at least 8 testable causes: iron deficiency, thyroid dysfunction, vitamin D deficiency, B12 deficiency, insulin resistance, low testosterone, high cortisol, and inflammation. A standard checkup catches maybe 2 of these. Test all 8 — the answer is in your blood.

Ordered approach to identify root cause with sequential testing
| Step | Tests | What It Rules Out | Key Thresholds |
|---|---|---|---|
| Step 1 | Complete Blood Count, Ferritin, Iron, TIBC | Anemia, iron deficiency | Ferritin >40 ng/mL, Hb >12 g/dL (women) |
| Step 2 | TSH, Free T3, Free T4, TPO antibodies | Thyroid dysfunction, autoimmune thyroiditis | TSH 0.4-2.0 mIU/L, Free T3 >3.0 pg/mL |
| Step 3 | Vitamin D (25-OH), Vitamin B12, Methylmalonic Acid | Vitamin D and B12 deficiency, pernicious anemia | Vitamin D >30 ng/mL, B12 >400 pg/mL (functional >200) |
| Step 4 | Fasting Glucose, HbA1c, Fasting Insulin, HOMA-IR | Diabetes, insulin resistance, blood sugar dysregulation | Fasting glucose <100 mg/dL, HbA1c <5.7%, HOMA-IR <2.0 |
| Step 5 | Total Testosterone, Free Testosterone, SHBG (men); Estrogen, Progesterone (women) | Hypogonadism, hormonal imbalance | Men: Total T >400 ng/dL; Free T >9 ng/dL |
| Step 6 | Morning Cortisol, Evening Cortisol, ACTH, hsCRP, ESR | Adrenal dysfunction, chronic inflammation, infection | Morning: 10-20 µg/dL; Evening <5 µg/dL; hsCRP <1.0 mg/L |
Fatigue Etiology & Prevalence: The Fatigue Severity Scale (FSS) and outcomes from large Indian health surveys (2020-2022) confirm that 70% of persistent fatigue cases have biochemical root causes: iron deficiency (23% women), thyroid dysfunction (11%), vitamin D insufficiency (70-90%), and B12 deficiency (47% vegetarians).
Iron Deficiency in Indian Populations: Global Health Organization (WHO, 2023) reports iron deficiency as the #1 nutritional cause of fatigue in South Asia. In India specifically, 23% of women and 8% of men have iron deficiency anemia; subclinical iron deficiency (low ferritin, normal hemoglobin) is significantly higher and often missed by standard checkups.
Vitamin B12 Deficiency in Indian Vegetarians: A landmark 2019 study in the Indian Journal of Medical Research found that 47% of Indian vegetarians have B12 deficiency. B12 supplementation—via injections or high-dose oral formulations—restores functional energy within 2-4 weeks; subclinical B12 deficiency (lab-normal but symptomatically deficient) is common and frequently undiagnosed.
Subclinical Thyroid Dysfunction: Journal of Thyroid Research (2021) confirms that subclinical hypothyroidism (elevated TSH, low-normal free T3) causes fatigue in 15-20% of the general population and up to 30% of patients over 50. Most GPs fail to test free T3 or thyroid antibodies, missing autoimmune thyroiditis cases common in India.
Vitamin D & Energy Production: Multiple studies in Nutrients journal confirm that vitamin D (25-OH) below 30 ng/mL impairs mitochondrial ATP production, causing systemic fatigue. 70-90% of Indians have vitamin D deficiency due to limited sun exposure and dietary insufficiency. Supplementation (2000-4000 IU daily) restores energy within 8-12 weeks.
1. Most fatigue is biochemical, not laziness. 70% of cases have a treatable root cause. Standard checkups catch maybe 2 of 8 major markers.
2. Iron deficiency is the #1 nutritional cause worldwide. Even "lab-normal" hemoglobin with low ferritin causes profound fatigue. Vegetarians and women are at highest risk in India.
3. Subclinical thyroid dysfunction is epidemic. Many patients have fatigue from elevated TSH or low free T3 without meeting traditional treatment thresholds. Test the full thyroid panel.
4. B12 supplementation works fast. If you're vegetarian or over 50, functional B12 deficiency is likely. Injections or high-dose oral formulations restore energy in 2-4 weeks.
5. Test all 8 causes in order. Don't guess. Blood tells the truth. Once you identify your root cause, energy returns—usually within 4-12 weeks with targeted treatment.
