Hi Thanks for posting your query on HCM I have read and understood your concern Amour thyroid is know for weight loss among its weight loss effect.However, synthroid may have among its side effect weight loss or weight gain depending on individual.Since you may not be able to get amour thyroid for now, synthroid may still help take care of your thyroid issues. I will advise you resort to physical/lifestyle measures to control weight.You generally put on weight when you eat more than you work, that is, energy from food exceeds energy used for your daily activities.I will suggest you try the following measures: -Regular physical exercises -Eat only when hungry -Eat in small quantities -Cut Back on Sugars and Starches -Eat Protein, Fat and Vegetables -Avoid sugary drinks and fruit juice -Drink water an half hour before meals -Eat soluble fiber -Drink coffee or tea -Sleep/rest well and avoid stress Hope this will help.You may write back if more concerns Wish you good health Dr Mbuomboh
