Whenever i eat or drink anything i feel i have to poop immediately. when i go not much comes out. i have been feeling really jittery internally lately. ive also been feeling a little tired. no weight loss or blood in stool. what could this be?

Urgent bm: This may be a hyperactive gastrocolic reflex. Drinking or eating sets off waves of intestinal contractions. resulting in an urgent urge to have a bm. Irritable bowel syndrome is another possibility. This reflex can be blunted by taking dicyclomine 1/2 hour before drinks or meals. Also get checked for hypoglycemia(low blood sugar) and thyroid disorder.
