Hyperthyroid (overactive) symptoms
How this Thyroid Risk Calculator works
Enter your age, gender, family history of thyroid disorder, a symptoms checklist (13 hypo- and hyperthyroid symptoms), recent stress level, and (for women) pregnancy or postpartum in the last 12 months.
We apply weighted symptom scoring plus demographic risk multipliers (age 30–60, female sex, family history, stress, postpartum) to estimate your screening risk score (Low / Moderate / High), flag the most likely type (hypothyroid vs hyperthyroid), recap key symptoms flagged, and recommend: consult your doctor and request a TSH blood test.
Logic: Each symptom adds 6–12 weighted points. Demographic factors add up to +74 points. Total is normalized to 0–100. Hypo vs hyper type is determined by comparing weighted symptom group totals. This is a risk screening tool, not a diagnosis.

Thyroid Disorder Risk Assessment Calculator – Symptoms Checker, Hypothyroidism Risk India & TSH Test Guide
Millions search "thyroid risk calculator", "thyroid symptoms checker", "hypothyroidism risk India", and "do I have thyroid problem" each year— especially women aged 30–50 who experience fatigue, unexplained weight change, hair loss, or mood shifts. Thyroid disorders affect an estimated 8–12% of Indian adults, yet many remain undiagnosed for years. Our free Thyroid Disorder Risk Assessment Calculator uses weighted symptom scoring across 13 hypo- and hyperthyroid symptoms, plus demographic risk multipliers (age 30–60, female sex, family history, stress, pregnancy/postpartum) to estimate your screening risk level (Low, Moderate, High), flag the most likely type (hypothyroid vs hyperthyroid), recap key symptoms flagged, and recommend: consult your doctor and request a TSH blood test.
Pair results with our Metabolic Age Calculator, Mental Wellbeing Calculator, and Life Expectancy Calculator for a complete picture of how thyroid health affects metabolism, mood, and long-term wellness.
Why Screen for Thyroid Disorder Risk?
The thyroid gland produces hormones (T4 and T3) that regulate metabolism, heart rate, body temperature, energy, mood, and menstrual cycles. When production is too low (hypothyroidism) or too high (hyperthyroidism), symptoms develop gradually—often mistaken for stress, ageing, or anaemia. In India, iodine intake variability, autoimmune Hashimoto's thyroiditis, and limited routine TSH screening contribute to high undiagnosed rates, particularly among women.
A simple TSH blood test (₹200–600 at most Indian labs) detects most thyroid problems early. Treatment with levothyroxine (hypothyroid) or antithyroid drugs (hyperthyroid) is highly effective when started promptly. This calculator helps you decide whether to request that test— it does not replace medical diagnosis.
1What You Enter
Demographics & history
- Age — numeric (12–100 years)
- Gender — Male or Female
- Family history of thyroid disorder — Yes / No
- Recent stress level — Low / Moderate / High
- Pregnancy or postpartum in last 12 months (women only) — Yes / No
Symptoms checklist (multi-select)
- Hypothyroid: Fatigue, weight gain, hair loss, cold intolerance, brain fog, dry skin, constipation, depression, irregular periods
- Hyperthyroid: Palpitations, weight loss, heat intolerance, anxiety
Example (moderate risk — woman, 38)
Female, age 38, family history yes, fatigue + weight gain + hair loss + cold intolerance, moderate stress → Moderate risk, hypothyroid pattern flagged, TSH test recommended.
Example (high risk — postpartum)
Female, 32, postpartum yes, palpitations + anxiety + weight loss + fatigue → High risk, mixed pattern, urgent TSH + Free T4 recommended.
2Formulas & Logic — Weighted Symptom Scoring
Symptom weights (points each when selected)
Hypothyroid symptoms: Fatigue (10), Weight gain (12), Hair loss (8), Cold intolerance (10), Brain fog (8), Dry skin (6), Constipation (8), Depression (8), Irregular periods (10). Hyperthyroid symptoms: Palpitations (10), Weight loss (12), Heat intolerance (10), Anxiety (8).
Demographic risk multipliers
Age 30–60 (+12) · Female sex (+15) · Family history yes (+20) · Stress moderate (+8) / high (+15) · Pregnancy/postpartum last 12 months (+12, women only).
Risk score normalization
Risk Score = min(100, round(Total Raw Score ÷ 130 × 100))
Low ≤ 30 · Moderate 31–55 · High > 55
Type determination (hypo vs hyper)
Compare weighted hypo score vs hyper score. If one exceeds the other by ≥25%, that type is flagged. Both elevated → Mixed pattern. Neither dominant → Unclear.

Thyroid Disease in India — Key Statistics
- Prevalence: 8–12% of Indian adults have thyroid dysfunction; hypothyroidism is 5–8× more common than hyperthyroidism
- Gender gap: Women are affected 5–8× more often than men, especially ages 30–50
- Autoimmunity: Hashimoto's thyroiditis (autoimmune hypothyroid) is the leading cause in iodine-sufficient regions
- Postpartum: 5–10% of women develop postpartum thyroiditis within 12 months of delivery
- Subclinical disease: Mildly elevated TSH (4–10 mIU/L) affects millions who feel unwell but are never tested
- Goitre belt: Iodine deficiency historically caused goitre in Himalayan and Gangetic regions—now less common with iodized salt
TSH Test Guide — What to Expect
TSH (Thyroid-Stimulating Hormone) is the best initial screening test. The pituitary gland releases TSH to signal the thyroid to produce T4/T3. High TSH = underactive thyroid (hypothyroid); low TSH = overactive thyroid (hyper).
| TSH | Interpretation | Typical next step |
|---|---|---|
| < 0.4 mIU/L | Possible hyperthyroidism | Free T4, Free T3, maybe TSI/TRAb |
| 0.4 – 4.0 mIU/L | Normal range (most labs) | Repeat if symptoms persist |
| 4.0 – 10 mIU/L | Subclinical hypothyroidism | Free T4, anti-TPO; treat if symptomatic |
| > 10 mIU/L | Overt hypothyroidism likely | Free T4; start levothyroxine if confirmed |
Fasting is not required for TSH. Avoid biotin supplements 48–72 hours before testing—they can falsely alter results. Take morning blood sample for consistency.
Worked Example — Step-by-Step
A 38-year-old woman with family history yes, symptoms: fatigue, weight gain, hair loss, cold intolerance, moderate stress, not postpartum:
- Hypo symptoms: Fatigue (10) + Weight gain (12) + Hair loss (8) + Cold intolerance (10) = 40 pts
- Hyper symptoms: None = 0 pts
- Demographics: Age 30–60 (+12) + Female (+15) + Family history (+20) + Moderate stress (+8) = 55 pts
- Total raw score: 40 + 55 = 95 pts
- Risk score: 95 ÷ 130 × 100 ≈ 73/100 — High risk
- Likely type: Hypothyroid (underactive thyroid)
- Recommendation: Consult doctor and request TSH test (+ Free T4 and anti-TPO if abnormal)
Risk Level Tiers (Educational)
| Level | Score | Action |
|---|---|---|
| Low | ≤ 30 | Monitor symptoms; routine check if family history |
| Moderate | 31–55 | Request TSH test at next doctor visit |
| High | > 55 | Prompt TSH + Free T4; consider endocrinology referral |
What Is the Thyroid Gland?
The thyroid is a butterfly-shaped gland in the front of your neck, just below the Adam's apple. It produces two main hormones: thyroxine (T4) and triiodothyronine (T3). These hormones control how fast your body burns energy (metabolism), regulates heart rate, body temperature, digestion, muscle function, brain development, bone health, and menstrual cycles.
The pituitary gland in your brain releases TSH (thyroid-stimulating hormone) to tell the thyroid how much T4/T3 to make. When thyroid hormone levels drop, TSH rises to stimulate production (hypothyroid). When levels are too high, TSH falls (hyperthyroid). This feedback loop is why TSH is the best first screening test.
A normal adult thyroid weighs about 15–25 grams. Enlargement (goitre) can signal iodine deficiency, nodules, or autoimmune disease. Most thyroid problems develop slowly over months or years—which is why symptom checkers like this calculator help identify when to get tested before complications arise.
Hashimoto's vs Graves' Disease — Main Causes
| Feature | Hashimoto's thyroiditis | Graves' disease |
|---|---|---|
| Type | Autoimmune hypothyroid | Autoimmune hyperthyroid |
| Mechanism | Immune system attacks thyroid → underproduction | Antibodies stimulate thyroid → overproduction |
| Common symptoms | Fatigue, weight gain, cold intolerance | Palpitations, weight loss, heat intolerance |
| Antibody test | Anti-TPO, anti-thyroglobulin | TSI (thyroid-stimulating immunoglobulin) |
| Prevalence in India | Most common cause of hypothyroid | Most common cause of hyperthyroid |
| Treatment | Levothyroxine (daily tablet) | Antithyroid drugs, radioiodine, or surgery |
| Who is affected | Women 30–50 most often | Women 20–40 most often |
Both are autoimmune conditions with strong genetic links—if a parent or sibling has one, your risk rises significantly. Our calculator adds +20 points for positive family history to reflect this.
Symptom-by-Symptom Guide — What Each Sign Means
Hypothyroid symptoms explained
- Fatigue: Low T3/T4 slows cellular energy production; often the first and most persistent symptom
- Weight gain: Metabolism drops 10–30%; fluid retention adds 2–5 kg even without overeating
- Hair loss: Hair follicles enter resting phase; eyebrows may thin at outer edges (Queen Anne sign)
- Cold intolerance: Reduced heat production; cold hands and feet year-round
- Brain fog: Slowed cognition, poor concentration, memory lapses—often mistaken for stress
- Dry skin: Reduced sweat and oil gland activity; cracked heels and brittle nails
- Constipation: Slowed gut motility; bowel movements less frequent than usual
- Depression: Low thyroid affects serotonin pathways; antidepressants may fail until thyroid is treated
- Irregular periods: Anovulation, heavy or scant cycles, fertility difficulty
Hyperthyroid symptoms explained
- Palpitations: Heart rate 90–120+ at rest; may feel skipped beats or pounding chest
- Weight loss: Metabolism increases 30–50%; appetite may increase but weight still drops
- Heat intolerance: Excessive sweating, preferring cool environments, warm moist skin
- Anxiety: Nervousness, irritability, tremor in hands, difficulty sleeping despite fatigue
Hyperthyroid symptoms often develop faster (weeks to months) than hypothyroid (months to years). Unexplained weight loss with a normal appetite is a red flag—do not celebrate it without medical evaluation.
Full Symptom Weight Reference Table
Our calculator assigns higher weights to symptoms most specific to each thyroid type. Weight gain and weight loss receive the highest points (12 each) because they strongly differentiate hypo from hyper patterns.
| Symptom | Type | Points |
|---|---|---|
| Fatigue | Hypo | 10 |
| Weight gain | Hypo | 12 |
| Hair loss | Hypo | 8 |
| Cold intolerance | Hypo | 10 |
| Brain fog | Hypo | 8 |
| Dry skin | Hypo | 6 |
| Constipation | Hypo | 8 |
| Depression | Hypo | 8 |
| Irregular periods | Hypo | 10 |
| Palpitations | Hyper | 10 |
| Weight loss | Hyper | 12 |
| Heat intolerance | Hyper | 10 |
| Anxiety | Hyper | 8 |
Second Worked Example — Hyperthyroid Pattern
A 45-year-old man, no family history, symptoms: palpitations, weight loss, heat intolerance, anxiety, high stress:
- Hypo symptoms: None = 0 pts
- Hyper symptoms: Palpitations (10) + Weight loss (12) + Heat intolerance (10) + Anxiety (8) = 40 pts
- Demographics: Age 30–60 (+12) + Male (0) + No family history (0) + High stress (+15) = 27 pts
- Total raw score: 40 + 27 = 67 pts
- Risk score: 67 ÷ 130 × 100 ≈ 52/100 — Moderate risk
- Likely type: Hyperthyroid (overactive thyroid)
- Recommendation: Urgent TSH + Free T4; seek care sooner if palpitations worsen
Complete Thyroid Blood Test Panel
After your screening score, your doctor may order some or all of these tests depending on symptoms and initial TSH result:
| Test | What it measures | When ordered |
|---|---|---|
| TSH | Pituitary signal to thyroid | First-line screening for everyone |
| Free T4 | Active thyroid hormone in blood | If TSH abnormal or symptoms persist |
| Free T3 | Most active thyroid hormone | If hyperthyroid suspected or T4 normal but symptomatic |

Thyroid Test Costs in India (Approximate)
| Test | Cost range | Turnaround |
|---|---|---|
| TSH alone | ₹200 – ₹600 | 24–48 hours |
| TSH + Free T4 | ₹500 – ₹1,200 | 24–48 hours |
| Full thyroid panel (TSH, T4, T3, antibodies) | ₹1,500 – ₹3,500 | 2–3 days |
| Thyroid ultrasound | ₹800 – ₹2,000 | Same day |
| Endocrinologist consultation | ₹500 – ₹2,000 | By appointment |
Costs vary by city, lab chain (Thyrocare, Dr Lal PathLabs, SRL, Metropolis), and whether done at home collection vs lab visit. Many corporate health check-ups include TSH at no extra charge.
Treatment Options After Diagnosis
Hypothyroidism treatment
- Levothyroxine (Eltroxin, Thyronorm): Daily tablet, taken empty stomach 30–60 min before breakfast
- Dose titration: Start low (25–50 mcg), recheck TSH in 6–8 weeks, adjust until TSH normalizes
- Lifelong therapy: Most Hashimoto's patients need lifelong treatment; stopping causes relapse
- Cost: ₹50–200/month for generic levothyroxine in India
- Monitoring: TSH every 6–12 months once stable; more often during dose changes or pregnancy
Hyperthyroidism treatment
- Antithyroid drugs (Carbimazole, Methimazole): Block hormone production; 12–18 month course for Graves'
- Radioiodine (I-131): Destroys overactive thyroid tissue; may lead to hypothyroid requiring levothyroxine
- Surgery (thyroidectomy): For large goitre, nodules, or when drugs/radioiodine unsuitable
- Beta-blockers (Propranolol): Short-term for palpitations and tremor while awaiting definitive treatment
Iodine, Diet & Thyroid Health in India
Iodine is essential for T4/T3 production. India's universal salt iodization program (since 1983) dramatically reduced goitre in the "goitre belt" (Himalayan and Gangetic plains). However, both iodine deficiency and excess iodine can trigger thyroid dysfunction—balance matters.
- Use iodized salt — most Indian table salt is iodized; avoid switching to rock salt (sendha namak) long-term without iodine sources
- Limit raw cruciferous vegetables in excess (cabbage, cauliflower, broccoli) — contain goitrogens that may interfere with iodine uptake in susceptible people
- Selenium-rich foods (Brazil nuts, eggs, fish) support thyroid enzyme function
- Avoid excess kelp/seaweed supplements — can cause or worsen hyperthyroidism
- Biotin supplements can falsely alter TSH/T4 lab results — stop 48–72 hours before blood draw
- Soy in large amounts may reduce levothyroxine absorption — take thyroid medication separately from soy milk or high-soy meals
Diet alone cannot cure autoimmune thyroid disease, but supports treatment effectiveness. Track overall nutrition with our Calorie Calculator and Micronutrient Deficiency Calculator.
Thyroid, Pregnancy & Fertility
Thyroid hormone is critical for fetal brain development in the first trimester—before the baby's own thyroid is functional. Untreated hypothyroidism in pregnancy increases risks of miscarriage, preterm birth, low birth weight, and developmental issues.
- Pre-conception: Women with known hypothyroidism should have TSH < 2.5 mIU/L before trying to conceive
- During pregnancy: TSH targets are tighter (often < 2.5 in 1st trimester); levothyroxine dose usually increases 25–50%
- Postpartum thyroiditis: 5–10% of women; our calculator flags recent pregnancy/postpartum as a risk factor (+12 points)
- Fertility: Hypothyroidism causes anovulation and irregular cycles—treating thyroid often restores fertility without IVF
Also assess fertility patterns with our Fertility Calculator and PCOS Risk Calculator— thyroid and PCOS symptoms overlap significantly.
Preparing for Your Doctor Visit — Checklist
Bring your calculator PDF export and this checklist to make the most of your appointment:
- Symptom timeline: When did each symptom start? Getting worse, stable, or improving?
- Family history details: Who had thyroid disease? Hashimoto's, Graves', goitre, or thyroid cancer?
- Current medications: Including biotin, iodine supplements, amiodarone, lithium (all affect thyroid)
- Pregnancy history: Recent delivery, miscarriage, or fertility treatment
- Specific request: "Please order a TSH test" — many GPs skip this unless asked
- Neck exam: Ask doctor to feel your thyroid for enlargement or nodules

- Export this calculator's PDF to show your symptom pattern and risk score
Lifestyle Tips to Support Thyroid Health
- Get tested if symptomatic — do not wait for symptoms to become severe; early treatment prevents complications
- Take levothyroxine consistently — same time daily, empty stomach, 4 hours apart from calcium/iron supplements
- Manage stress — yoga, meditation, adequate sleep; use our Stress Load Calculator to track load
- Regular exercise — supports metabolism and mood; adjust intensity if hyperthyroid with palpitations
- Monitor weight trends — sudden unexplained change warrants testing even without other symptoms
- Annual TSH if high-risk — women 30+, family history, prior thyroid disease, or autoimmune conditions
- Re-run this calculator after lifestyle changes or if new symptoms develop
Thyroid & Metabolic Health Connection
Thyroid hormone is the master regulator of your basal metabolic rate (BMR). Hypothyroidism can reduce BMR by 15–40%, making weight management extremely difficult despite diet and exercise. Hyperthyroidism has the opposite effect—increasing calorie burn and muscle breakdown.
Untreated hypothyroidism also raises LDL cholesterol, worsens insulin resistance, and increases cardiovascular risk—overlapping with our Cardiovascular Risk Calculator and Diabetes Risk Calculator inputs. Treating thyroid often improves cholesterol and glucose without additional medication.
Check how thyroid may affect your overall metabolic age with our Metabolic Age Calculator and BMR with our BMR Calculator.
Conditions That Mimic Thyroid Symptoms
Many non-thyroid conditions cause overlapping symptoms—another reason blood tests are essential:
- Anaemia / iron deficiency — fatigue, hair loss, cold hands (check CBC, ferritin)
- Type 2 diabetes — fatigue, weight change (check HbA1c)
- Depression & anxiety — mood, energy, sleep overlap
- PCOS — irregular periods, weight gain, hair changes
- Vitamin D / B12 deficiency — fatigue, brain fog
- Chronic stress & burnout — fatigue, weight fluctuation
When to Seek Urgent Medical Care
- Severe palpitations with chest pain or shortness of breath
- Sudden rapid weight loss with fever and agitation (thyroid storm risk)
- Neck swelling with difficulty breathing or swallowing
- Extreme fatigue with confusion or very low heart rate (myxedema coma risk—rare but emergency)
- Eye bulging, double vision, or severe eye pain (Graves' ophthalmopathy)
