Should I Try To Regain Weight After Losing 10 Kg On Galvus/Met?

Hi. I am on Galvus/met 50/1000 twice a day and over a period of roughly 2 years, I lost 10 kg. I still eat well and have a good appetite. All my vitals are very good and in fact my GP said to me that I am a “model patient”. The problem is, people look at you and make scary remarks about the weight loss. Is it advisable to try and regain the weight? What do I have to do?
