So, this month i have observed that i had nausea, stomach pressure and acidity and weight loss despite trying. So, did and ugendoscopy, results were antral gastritis and h pylori positive. I have been put on nexpro L, gaviscopn syrup, hpylori kit and one probiotic. Its been 8 days since i have eating this medicine, 7 more days to go, but what i am observing is, i am losing too much weight, and unable to gain weight even after eating normally. My symptoms have subsided and i feel great! But why i am not able to gain weight? Is this because of the h pylori/gastritis? After the treatment, can i expect weight gain? I am 65.5kg, last year i was 71kg, i used to do gym, lost 3-4 kgs there, but since December m not going to gym but still losing weight. I am scared. Also i have piles. Please guide me further. How do I gain weight?
