The course of the disease
The course of the disease depends on the cause of the intestinal cramps and diarrhoea. Acute infections and spoiled food usually cause severe symptoms for a few days, after which the symptoms quickly subside. Incompatibilities can cause the symptoms again and again when the triggering food is consumed, and the symptoms may worsen with each intake of the food. Chronic inflammatory bowel diseases occur intermittently, and it is not uncommon for the symptoms to worsen over the course of several years, so that stronger treatment options are necessary.
How contagious is it?
How contagious the intestinal cramps are with diarrhoea depends strongly on the disease that causes them. Infectious causes are basically contagious and can be transmitted from one infected person to another. Autoimmune diseases and food intolerances are not contagious. An increased susceptibility to the diseases can at best be passed on from parents to children via genetic imprinting.
