There isn't sufficient information to suggest a specific diagnosis. I would advise you to visit the ER so that you can be examined and undergo necessary investigations to find the underlying cause and have it treated accordingly. You may require a deworming medicine and an antacid. These following steps may help:
- Don't skip meals, you may not feel like eating but in such conditions you should have the reduced amount in frequent intervals(i.e. 3 square meals broken down to 5 or 6 as you can tolerate) and slowly increase as you get better.
- Reduce/ Avoid spicy,fried, fatty, junk and oily food
- Avoid/ Limit drinking coffee, tea and carbonated drinks to once a day
- Exercise regularly (30-45 mins/day)
- Increase daily intake of water to 3 liters
- Avoid/Stop smoking and drinking if you have the habit
- Reduce stress through methods such as yoga/meditation.
