Hi, Seems intestinal infection due to any invading pathogen either food or water induced. Some strict guidelines will take you out from this. • Consume plenty of liquids preferably boiled water, coconut water, lemon juice, green tea, coffee, butter milk, etc. • Small amount of light diet with fresh curd at intervals. • Avoid all junk foods, beverages, non-vegetarian, oily, spicy stuffs. • Avoid prolong fasting and overeating. • In our clinic we recommend to give proton pump inhibitors as Prilosec and Tylenol, probiotics, and gut specific antibiotics as per the case evaluations. • Avoid smoking/alcohol if using. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Bhagyesh V. Patel
