what happens when levothyroxine dosage is too high?
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.
Many of the signs of hyperthyroidism caused by taking too much levothyroxine can be found in the skin. Too much levothyroxine can make the skin unusually warm, due to increased blood flow. Levothyroxine also increases metabolism, causing your body to generate more heat.
