Thanks for your query
You never fast for your symptom relief because it will aggravate your symptoms.
Insted you should
1. take frequent food but low in quantity,
2. avoid spicy food,
3. take bland diet,
4. avoid smoking
if you are a smoker,
5. dont consume alcohol
6. drink water in plenty around 4 litre/day
Along with these you should take pantoprazole
40 mg once daily in empty stomach and digestive enzymes after food. You may also have ornidazole-ofloxacin
combination thrice daily for 7 days to control mucous stool.
