From the past 2-3 months, i have noticed a drastic changes in my weight, which getting less and i am getting thin day by day. My appetite is all good and i was suffering from mild gastritis and anxiety from the past 6 months, so i am on PPI from 4 months and on anti depressant from 1 month. I do not know why such changes in weight is seen. No weakness, no tiredness felt. Few months back i have done CBC also, where heamoglobin was pretty much and all other points were in normal ranges. In these 4-5 months i have lost 3.5 KG. Are this weight loss symptoms are of serious condition ?.
