Hi, I understand your concerns. Since you are unable to gain weight with a background of hyperthyroidism it's firstly important to ensure that your Thyroid hormones levels are in check. Your current dose of medicines for hyperthyroidism is something we need to see along with your reports from the time of diagnosis till date. If you have a thyroid ultrasound or a thyroid scan, that would be helpful too. The next thing to consider is your diet. A balanced diet with a gradually increasing calorie intake along with an exercise helps in a realistic way of gaining weight. And lastly, do get your blood sugar checked.

If you have hyperthyroidism and are struggling with being underweight, the key is to first control your thyroid levels and then focus on healthy weight gain strategies. 1. Treat the Underlying Hyperthyroidism • Anti-thyroid medications like Methimazole (MMI) or Propylthiouracil (PTU) help balance thyroid hormone levels. • Beta-blockers (e.g., Propranolol) can help with symptoms like rapid heartbeat. • If medication alone is not enough, radioactive iodine therapy or surgery may be needed. 2. Diet for Healthy Weight Gain • Increase calorie intake: Eat 5–6 small meals a day with nutrient-dense foods. • Healthy carbs: Add whole grains, potatoes, oats, and bananas. • Protein-rich diet: Eggs, chicken, fish, tofu, lentils, and dairy help build muscle. • Healthy fats: Include nuts, seeds, avocados, and olive oil. • Smoothies & shakes: Make calorie-dense shakes with milk, nuts, and protein powder. 3. Strength Training & Exercise • Resistance training (e.g., weight lifting, yoga) helps gain muscle instead of fat. • Avoid excessive cardio, which can further speed up metabolism. 4. Get Enough Sleep & Reduce Stress • Poor sleep and stress can worsen hyperthyroidism and prevent weight gain. • Try relaxation techniques like meditation & deep breathing. 5. Regular Checkups • Monitor TSH, T3, T4 levels regularly. • If your thyroid levels are still high, weight gain will be difficult.
