Too much levothyroxine can also affect your digestive tract. Many people lose weight, despite a normal or increased appetite. Excess levothyroxine can also cause more frequent bowel movements or diarrhea, as the hormone speeds the movement of food through the digestive tract.
Even then, if you don't follow your doctorâs instructions closely and take your medication properly, you could throw your hormone levels out of whack. Finding the Right Dose of Thyroid Medication. To determine your levothyroxine dosage, your doctor will draw your blood to test for thyroid-stimulating hormone (TSH). This test measures how much thyroid hormone your body is asking your thyroid gland to make. The higher your TSH level, the more starved your body is for thyroid hormone â a sign that your doctor needs to increase your dose of the synthetic replacement hormone.
