Can Thyroid Problems Cause Weight Gain, Hair Fall And Feeling Cold?

Yes, these symptoms together can point to an underactive thyroid (hypothyroidism). When the thyroid makes too little hormone, the body slows down, which can cause weight gain, tiredness, feeling cold, dry skin, constipation and hair loss. Low iron, low vitamin D, poor sleep and stress can cause similar symptoms, so a blood test is the only way to know. Thyroid problems often run in families, so your mother's history makes it even more worth checking.

Ask for a blood test that checks TSH and T4 (thyroid hormones), along with your iron and vitamin D levels. If the thyroid is underactive, it is usually treated very well with a daily tablet, and weight and hair often improve over a few months. An endocrinologist can confirm the diagnosis and set the right treatment for you.
