Am recently very over weight & not active as before-very out of shape. a few weeks ago feet & hands start to swell at times, is it because of weight?

Allergies could also cause swelling of hands ; feet, but usually there is rash or ichiness too. Hypothyroidism could also cause weight gain ; swelling of hands ; feet that should also be checked by your physician.
