Hello dear Warm welcome to Healthcaremagic.com I have evaluated your query in details . * Seems residual stomach infection still remaining . * Primary guidelines for better outcome Consume plenty of liquids in form of boiled water , lemon juice , coconut water , home made juices , organic tea , coffee , butter milk etc . Prefer soft , light , bland , vegan diet with fresh curd preferably . Avoid all types of oily , spicy , non veg , hot beverages , junk foods , dairy fat , milk , aerated drinks till recovery . Intake of PPI ( as omeprazole ) , antibiotics ( with metronidazole on pack ) Racecadrotil as an anti secretory agent help faster recovery , which requires prescription with your doctor .
