You may also have a TSH test, along with other tests, to help diagnose unusual bumps or lumps on your thyroid that may be thyroid cancer or thyroid nodules (growths on your thyroid that aren't cancer). ![]() Not having enough thyroid hormone slows down your body functions and causes symptoms that include: Hypothyroidism (too little thyroid hormone) is also called underactive thyroid. Frequent bowel movements (pooping a lot).Sweating or being very sensitive to heat.Weight loss, even though you may be eating more than usual.Having more thyroid hormones than you need speeds up your body functions and causes symptoms that include: Hyperthyroidism (too much thyroid hormone) is also called overactive thyroid. You may need a TSH test if you have symptoms of too much or too little thyroid hormone in your blood. By measuring TSH levels in your blood, you can find out if your thyroid is making the right level of hormones. If your thyroid hormone levels are too high, the pituitary gland makes little or no TSH. If the thyroid hormone levels in your blood are too low, your pituitary gland makes larger amounts of TSH to tell your thyroid to work harder. ![]() TSH tells your thyroid how much thyroid hormone it needs to make. The pituitary gland makes thyroid stimulating hormone (TSH). Your thyroid is controlled by a gland in your brain, called the pituitary gland. If you have too much, many body functions speed up. If you don't have enough thyroid hormones in your blood, many of your body functions slow down. They help control your weight, body temperature, muscle strength, and even your mood. Thyroid hormones affect nearly every organ in your body, including your heart. Your thyroid makes hormones that control how your body uses energy. The thyroid is a small, butterfly-shaped gland in the front of your neck. TSH levels that are too high or too low may be a sign of a thyroid problem. A TSH test is a blood test that measures this hormone. doi:10.3121/ stands for thyroid stimulating hormone.
