Hello, Most important is intestine infection through some sort of bacteria or the virus which may be ingested via contaminated food or liquid. Primary working tips in this regards are Consume plenty of liquids in the form of boiled water, lemon juice, coconut water, homemade juices, organic tea, coffee, and buttermilk etcetera. Prefer soft, light, bland, vegan diet with fresh curd preferably. Avoid all types of oily, spicy, nonveg, hot beverages, junk foods, dairy fat, milk, aerated drinks till recovery. Intake of PPI (as omeprazole), antibiotics (with metronidazole on the pack), probiotics with lactobacillus, antispasmodic agent as dicyclomine help faster recovery, which requires a prescription with your doctor.
