Unexplained weight gain? Blood tests that help find the reason

Weight usually goes up because of diet, less activity or poor sleep, but sometimes it climbs even when habits have not changed. An underactive thyroid, insulin resistance or hormonal problems like PCOD can make weight harder to control. Blood tests also show whether extra weight has started affecting your sugar, cholesterol or liver.

Tests to ask about

Thyroid profile (T3, T4, TSH)

Low thyroid slows metabolism and is one of the first things doctors rule out.

₹1,200 Book Details

HbA1c

Shows average sugar of the last 3 months – picks up prediabetes early.

₹420 Book Details

Fasting insulin

High insulin with normal sugar can suggest insulin resistance.

₹460 Book Details

Lipid profile (cholesterol)

Extra weight often raises triglycerides and LDL cholesterol.

₹620 Book Details

Liver function test (LFT)

Can give early hints of fatty liver linked with weight gain.

₹790 Book Details

PCOD hormone profile (women)

For women with weight gain plus irregular periods, acne or extra hair.

₹2,350 Book Details

Common reasons doctors look for

Underactive thyroid (hypothyroidism)
Insulin resistance or prediabetes, often with weight around the belly
PCOD/PCOS in women, often with irregular periods
Less activity, late-night eating and poor sleep
Water retention from kidney, heart or liver problems

How to prepare

If your tests include fasting sugar, fasting insulin or lipid profile, fast 10–12 hours overnight (water is fine) and give the sample in the morning. Thyroid and HbA1c can be done without fasting.

When to see a doctor

See a doctor if weight rises very quickly with swelling of legs or face, breathlessness, or if you notice purple stretch marks, a round face or very high blood pressure. Swelling with breathlessness when lying down needs urgent medical attention.

Weight Gain – FAQs

Which test should I do for weight gain?

Doctors commonly start with thyroid profile, fasting sugar or HbA1c and lipid profile. Fasting insulin and hormone tests may be added depending on symptoms.

Can thyroid cause weight gain?

An underactive thyroid can slow metabolism and cause some weight gain, along with tiredness and feeling cold. It is a common reason doctors check TSH first.

Why check cholesterol and liver for weight gain?

Extra weight, especially around the belly, is linked with high cholesterol and fatty liver. These tests show whether weight is already affecting your health.

Will the test tell me how to lose weight?

Tests can point to a medical reason, but a weight plan should be made with your doctor or dietitian based on the reports.

This page is general information, not medical advice or a diagnosis. Please talk to a doctor about your symptoms.
