Xenical Linked to Kidney Stones

People are always looking for a quick, easy fix, and the drug companies are ever so happy to accommodate them. Wouldn't it be nice if we could just swallow a pill and solve the obesity epidemic that has close to 70 percent of the U.S. population overweight? But it just isn't so.

That's why it's no surprise researchers have found another problem with Xenical. Patients could have a better chance of developing kidney stones if they take it, according to a study conducted on rats in Brazil.

Researchers tested the effect of Xenical (known generically as orlistat) in 39 adult rats that were given a diet rich in oxalate alone or combined with fat (soy oil). With Xenical, oxalate levels in the urine were four to eight times higher with Xenical than the baseline value elevating the risk of stone formation.

It has been suggested previously that some people can develop increased levels of urinary oxalate following treatment with Xenical, but this is the first study relating this effect to the type of diet. Foods that contain high levels of oxalate include:

  • Spinach
  • Rhubarb
  • Chocolate
  • Tea
  • Strawberries

Better understanding of your nutritional type will help you figure out what kind of diet you should be eating for your good health.
