I have a habit of eating green chilli but recently stop it and spicies in food.I generally consume less water. No alcohole consumption no fastfood. Hav a problem of acidity because sometimes I feel burning my upper abdomen and also food pipe. No other history of Chronic diseases. Sometimes reggargaration  sounds comming from stomach..
