HI Thank for asking to HCM Your query being taken care, weight loss may not be due to the digestive dysfunction, but it has to be look for systemic disease, you have not mentioned the weight here else it would have been compare with the normal range, you have even not mentioned the age here neither the gender. Now for the abdomen discomfort it could be due to digestive dysfunction that might caused the formation of flatus even caused the hyperacidity, try to change the diet, avoid greasy, spicy heavy meal, have light diet that is easy to digestive like green leafy vegetable, passing the stool three to four time in day is normal one. hope this information helps.
