I am 20 years old male, from several months i'm facing digestive issues, sometimes I get loose motions and if not that, the stools are mostly in liquid state, and on a regular basis I have mild stomach pain after I eat anything especially when I eat anything spicy or outside food, the next day itself I get loose motions and because of that my body is also losing weight, i'm now 49 kgs when last checked and my height is 5 ft 7 inches so i'm under weight also, I had shown it to my physician and he had given me medicines for a month for indigestion, acidity and also for worm issues but still the condition is same, I had also done sonography of my abdomen but the sonography report was completely normal, I had also had my blood tested and in the blood report many essentials like haemoglobin, etc were below the margin level, Dr. please advice what should be my next step? Should I show this to any gastroenterologist or to whom?
