What would an mri of the brain show us? And isnt he in renal failure... shouldnt you do a ct scan of the abdomen?

And why would it be malabsorption... she has been having this problem for 5 years...Yogurt does not cause lactose intolerance. Couldnt it be impaired intestinal motility (IBD?)

H
) Fluid restriction

H
) Increased estrogen

B
) Measurement of serum porphobilinogen level ( porphyria)

C
) Malabsorption ( lactose intolerance)

The symptoms of irritable bowel syndrome (IBS) resemble those of lactose intolerance and can easily be confused. Some patients with IBS can also have lactose intolerance. Restriction of milk products in these patients may relieve the symptoms of IBS.
Lactase deficiency is the most common form of disaccharidase deficiency. Enzyme levels are highest shortly after birth and decline with aging, despite a continued intake of lactose. Within the animal world, nonhuman mammals usually lose the ability to digest lactose as they reach adulthood. Some populations of the human species, including those of Asian, South American, and African descent, have a propensity for developing lactase deficiency. By contrast, races descended from northern Europe or from the northwestern Indian subcontinent are likely to retain the ability to absorb lactose into adulthood.

Symptoms of lactose intolerance include loose stools, abdominal bloating and pain, flatulence, nausea, and borborygmi. A diagnosis or even the suggestion of lactose intolerance leads many people to avoid milk and/or to consume specially prepared food with digestive aids, adding to health care costs.
