Hi,
Noted the history and understood the concerns.
Gastritis can be due to many a factors like
stress,
anxiety, hot spicy food, increased acid production and even any medicine including the pill you took.
Well, the management in general remains the same irrespective of the cause.
Take a PPI like Oeprazole.
Antacid every three hours particularly when you are on empty stomach.
Eat soft and bland diet in small quantity frequently.
Avoid spicy and oily food.
No aerated drinks please.
This should solve your problem.
Avoid stress and anxiety.
Do not worry, this will settle with these measures.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. T Chandrakant,
General Surgeon
