Hi, Welcome to Health care magic forum.
As you describe, You have P.C.O.D, and using the
metformin.
It is a good drug, and you you are confirmed of the cure of the P.C.O.D, you can stop it.
For gastric and
indigestion problems, you may feel the hungry all the time. Hence the over weight.
You can have the reduction of the weight by Avoiding the calories, fats, oils, junk foods, fleshy fruits like guava, and banana.
Practice, morning walk,
yoga, gardening, and house hold works like cleaning, keeping things in order etc.
Minimize the sleeping time, practice late to bed, and early to rise. Avoid the day time sleep.
wishing for a quick and complete recovery. Thank you.
