Take care of yourself while you're being treated for cancer. Eat well and get plenty of rest to save energy and keep your memory. The thyroid gland in your neck produces hormones that control how quickly your body burns food for energy. When your thyroid makes too little of its hormones called hypothyroidism your whole body slows down. You can feel tired, depressed, and forgetful. Your doctor will do a blood test to check your thyroid hormone levels. If they're low, you'll get thyroid hormone pills. If you're worried about memory loss, see your doctor.
