Why the body is swelling if TSH and Anti TPO is normal. I had test for thyroid disease bcz my body was swelling. The report says that everything is normal apart from deficiency of Vitamin -D. So I am not understanding if the reports are normal then why the body is swelling. It is swelling all around the body. Within 6 months I had gained almost 15 kg. So suggest me what to do right now at this stage What is the duration of swelling? >7 days Is it continuous or intermittent: Intermittent Is it on one side or both sides: Both sides Are you on any medications? No Did you recently get injured? Yes.
