Thanks for your query.
You should take extra precautions in your eating habits. Always take food or drink prepared in hygeinic conditions.
Metronidiazole 400 mg thrice a day along with Lactobacillus
preparation once a day and digestive capsules (containing fungal diastase and pepsin
) after meals for 5-7 days, will be helpful to you.
If the problem persists, you should get yourself examined by a Gastroenterologist.
I hope this is helpful to you.
