Thanks for your question on Chat Doctor. I can understand your concern. By your history and description, we should definitely rule out hypothyroidism in your case. So get done thyroid function test (Serum TSH, free T3 and T4). If all these are normal then no need to worry about hypothyroidism. Start exercising and follow healthy diet. Avoid stress and tension, be relaxed and calm.Don't worry, you will be alright with all these. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
