I am 29 year old and facing acidity problem since last 2 years. Vomit yellow fluid while brushing everyday, completely lost my appetite and if eat or drink something feels like I will vomit. Done ultrasound also doctor said acidity problem is there and also swelling in stomach and completed medicine also 6 months ago but my appetite isn't coming back even on taking appetite increasing syrup. What can I do to revive my appetite instantly and cure acidity problem since I am now underweight due to not eating properly and feels lazy all day.
