Thanks for your question on Healthcare Magic.
I can understand your concern.
By your history and description, possibility of
acute gastritis is more likely.
So give him
antacid (
pantoprazole) and prokinetic (levosulperide) twice daily before food.
Tell him to follow these lifestyle modifications.
1. Avoid large meals, instead take frequent small meals.
2. Avoid hot and spicy food.
3. Avoid
stress and tension, be relax and calm.
4. Go for walking after meals.
5. Put 2-3 pillows under head in bed.
6. Tell him to quit
smoking and alcohol if he is having these habits.
Don't worry, he will be alright with all these.
Hope I have solved your query. I will be happy to help you further. Wishing good health to your brother. Thanks.
