The amount of hormone your thyroid makes affects your weight, according to the National Institutes of Health (NIH).

If your thyroid is making too little of the hormone, you have a condition called hypothyroidism, which can cause weight gain, according to the NIH.

If, however, your thyroid is making too much of the hormone, you have a condition called hyperthyroidism, which can cause weight loss, according to the NIH.

These weight changes can be sudden, but typically they happen slowly over time, according to Premier HealthNet (PHN) physicians.

Talk to your doctor for more information about how a person’s thyroid affects their weight.
