Talk to General Physician on Swollen Body

Is there any non medical cure for swollen body? 2 years back my body got swollen and my skin got sagged. There were three notable factors, 1) i was living in a hot room(hostel on top floor and not good vantilation. I used to make my own clean food).2) I took a few pills of centrum silver(as a multivitamin, as i exhausted despite rest. But no effect on energy so stop taking). 3) my bowel movement chnged. It was like loose motion and badly stinky though my diet included 50% fruit. I moved back home and my swollen got 10% better. But not completly. Same for bowel movement and stomach. Are there any excercises to fix swollen body?
