what would happen if i took levothyroxine
A: Usually, when taking levothyroxine the side effect is weight loss rather than weight gain. This occurs because the thyroid hormone is what regulates metabolism. If you are hypothyroid, your metabolism is slower since you don't have as much thyroid hormone in your body.: Levothyroxine is a synthetic or man-made replacement for a hormone that is normally produced by the thyroid gland to regulate the body's energy and metabolism. It is used to treat hypothyroidism (low thyroid hormone levels) and to treat and prevent goiter (an enlarged thyroid gland).
