Welcome to healthcare magic,
Your symptoms are suggestive of
Acute Gastritis and it needs to be thoroughly with a proper health life style as suggested by my all colleagues.I would just add on those guidelines.
1.Stop
smoking and alcohol completely.
2.Eat at regular intervals while avoiding over eating.
3.Avoid oily/spicy/junk foods.
4.Drink a glass of milk after breakfast.
5.Don't lie down immediately after eating.
6.You can take Cap.
Omez 20mg twice daily 15 minutes before meals,its to be taken for atleast 2 weeks for an immediate long term effect.
Sucralfate suspension will help the immediate irritation to the stomach and thus the
vomiting after meals will be reduced,take it 2 tsp 4 times daily.
7.Do regular exercise.
I hope your queries must have been cleared very well by all of us.
Have a healthy life.
