From past 7 years I am facing the following troubles. 1) latrine (pooping) is not coming at a time ,I have to go 3 times where first time comes high volume, second and third time's very low volume. 2) frequent motions if I eat somewhat spicy food (like salt, pepper,masala items if somewhat high) I am also facing gastric troubles from past 6 months. Now my questions are: 1) which specialist should I consult 2) which tests should I undergo like USG of abdomen Please give me detailed answer.
