Will low testosterone cause anxiety and weight gain?

Low testosterone: is associated w/weight gain, especially around the middle. It also triggers mood changes such as irritability and anxiety. See your doc for lab study and treatment. Other hormones along the chain to testosterone may be the issue, such as DHEA but you need testing. Diagnostechs lab in Washington State has a good saliva test for this, and saliva is preferred to blood but blood works. Peace.
