<s>[INST] Hi I am a 19 year old male I used to be a heavy drinker and started getting lower abdominal sharp pains last year every time I ate. I was diagnosed with gastritis and couldnt eat almost anything,I recently got an endoscopy which showed no signs of ulcers or gastritis. I am still having abdominal pain I always feel bloated after eating anything. What can this be? [/INST] Good day! Your question has answers in it. Alcohol caused it so stop it. Use PPI's, And modify diet and lifestyle for better management. Stay in touch with your gastroenterologist for further managementFollowing things will HelloSign weight (if overweight)Avoiding alcohol, chocolate, citrus juice, and tomato-based productsAvoiding peppermint, coffee, and possibly the onion family[8]Eating small, frequent meals rather than large mealsWaiting 3 hours after a meal to lie downRefraining from ingesting food (except liquids) within 3 hours of bedtimeElevating the head of the bed 8 inchesAvoiding bending or stooping positions Also you need to be in touch with GI consultant to rule out other etiologies like H pylori or allergic or voluminous gastritis.
