What do you advise if i have constipation diarrhea and stomach cramps?

Diet therapy: Avoid milk, beans, fruit (and juice), and wheat. Also avoid any fiber except methyl cellulose (citrucil). You should measure the benefit within one week, two maximum. Most of these cases are from maldigestion of sugars which are fermented to methane, formate, butane, and propionic acid (swamp gas). No sugars: No fermentation. Most gluten intolerance is simple maldigestion.
