What is the link between a person’s thyroid and weight?

Medically Reviewed by Checkmark Medically Reviewed By: Sheela Krishnaswamy

Thyroid and metabolism are known to be linked with each other. When one is suffering from hypothyroidism, or when your thyroid isn’t producing enough hormones, your metabolism slows down. This reduces the quantity of calories that your body can burn, in turn leading to weight gain.

Contrastingly, when a person is suffering from hyperthyroidism and the thyroid gland is producing more hormones than required, your metabolism goes into overdrive, and your body starts burning more calories than normal resulting in weight loss.

However, this may not happen in every case. Every body reacts differently, and other factors, such as physical activity, diet, other hormones account for the weight loss or weight gain. Studies have shown that “obese people with a normal thyroid gland tend to have activation of the hypothalamic-pituitary-thyroid axis with higher serum TSH and thyroid hormones in serum. On the other hand, small differences in thyroid function are associated with up to 5 kg difference in body weight.”
