Does an overactive thyroid make you gain weight?

An overactive thyroid, or hyperthyroidism, is a condition in which the thyroid gland produces too much thyroid hormone. This can cause a number of symptoms, including weight loss, not weight gain. In fact, hyperthyroidism is more commonly associated with weight loss, rather than weight gain.

It's important to note that everyone's body is different, and some people may experience different symptoms of hyperthyroidism. While weight loss is a more common symptom, it is possible for some people to gain weight with hyperthyroidism. This can be due to several factors, including:

1. Increased appetite: Hyperthyroidism can increase your appetite, causing you to eat more and take in more calories.

2. Fluid retention: Hyperthyroidism can sometimes lead to fluid retention, which can cause a temporary increase in weight.

3. Underlying medical conditions: Some people with hyperthyroidism may have other medical conditions that can lead to weight gain, such as diabetes or Cushing's syndrome.

If you are concerned about your weight gain and think it may be related to hyperthyroidism, it's important to see a doctor to get a proper diagnosis and treatment. They can assess your symptoms, order tests to check your thyroid hormone levels, and determine the cause of your weight gain.
