Hello......Based on the TSH value you have mentioned in the report, I think you should know that your TSH value indicates hypothyroidism....The normal value ranges between 0.4 to 4.5 milliunits per liter....Generally high values are seen in infection of thyroid gland or hypothyroidism and low values in hyperthyroidism, toxic nodule..... It might be a reason your weight gain... So kindly consult consult a endocrinologist for further management...
