Why do i hiccup all the time?

How often do you have it and does it impair your daily activity? Dose any food or certain thing trigger it? Hiccup is normal if it happens once in a while but the etiology should be investigated if it happens almost daily and persists for hours which makes you miserable. You need to see a doctor if hiccup makes you miserable. If certain thing triggers the hiccup, avoidance is the best treatment.
