1.Hyperthyroidism
If your thyroid gland makes too much thyroid hormone, it revs up your metabolism so you burn more calories and lose weight. You also may have more bowel movements and a racing heartbeat, and you may feel anxious. Your doctor can help you manage it with medicine. They may also talk to you about surgery to take out all or part of your thyroid.
2.Diabetes
Insulin is a hormone your body makes to turn blood sugar into energy. If you have diabetes, you either can’t make insulin or can’t use it the way you need to. When your cells run out of fuel, your body thinks it’s starving and starts burning fat and muscle. This makes you lose weight. You may also be thirsty, tired, hungry, or pee more than usual. Talk to your doctor right away if you notice these symptoms. If you have diabetes, they can help figure out a treatment plan that’s right for you.
