Synthroid is not prescribed for weight loss. Treating low thyroid levels can help you keep from gaining more weight. But it may not help you lose the weight you’ve already gained. Other factors may be contributing, such as hormonal changes, poor sleep and nutrition, and low levels of physical activity. Treating hypothyroidism means taking a thyroid replacement medication like Synthroid. The amount you take can change depending on your blood work and symptoms, so it may take a few months to find the right dose for you. If you’re still having difficulty losing the extra weight, you may need to make other diet and lifestyle changes.
