Hi, welcome to the ehealth forum and I am glad to help you.
You seem concerned by the compulsion to go to the toilet twice/thrice to the toilet for motion after taking something like food, liquid etc.
This might be the result of the normal gastrocolic reflex that whenever you eat/drink something you feel the need to go to the toilet. You need not worry about the same if everything else is normal i.e. your weight and appetite are normal and there are no other complaints such as abdominal pain, diarrhea, constipation etc.
Clinically, the gastrocolic reflex has been implicated in pathogenesis of irritable bowel syndrome: the very act of eating or drinking can provoke an overreaction of the gastrocolic response in some patients with irritable bowel syndrome due to their heightened visceral sensitivity, and this can lead to abdominal pain, diarrhoea, or constipation.
You can consult your personal physician for the evaluation of the same and appropriate management as the same is not possible online.
Hope this helps. Take care.
