A study released today sends out a strongly worded warning about risks of kidney, liver, and other organ damage from the most popular weight drugs on the market. According to a University of Rhode Island study funded by the National Institutes of Health (NIH), orlistat, which goes by the prescription brand name Xenical and the over-the-counter name Alli, can cause "severe toxicity" to major internal organs. The research results obtained by pharmacology professor Bingfan Yan were worrying enough that he immediately reported the results to the FDA, which approved orlistat in 1999. Liver and kidney damage are serious enough, but Yan's team also reported another finding, just as concerning, that orlistat's metabolic action reduces the effectiveness of many medications, including life-saving cancer treatments. In fact, the researchers reported that cancer cells multiplied faster under the influence of orlistat. Orlistat also boosts the anti-clotting effects of aspirin, raising the risk of bleeding both internal and external. Yan and his team found that orlistat - even at low doses - limits the function of a key enzyme called carboxylesterase-2, which has an important role in detoxifying the liver, kidneys, and entire gastrointestinal tract. pushing lasix too fast A few weeks ago, a middle-age patient who has been taking orlistat regularly for weight loss asked about the increased risk of developing cancer, especially colon cancer, with prolonged intake of the product.

Therefore, common side effects experienced by those who take it include oily stools, fecal spotting, diarrhea and abdominal pain. They called these cells as “aberrant cryptic foci.” The experts were divided whether or not these are real precursors of colon cancer. I remember a patient telling me this about her experience with orlistat: “I don’t trust it when I fart, because almost always, something goes with it.” Despite the “small accidents” one can have with orlistat, a lot of patients doctors prescribed it to seem not to mind because they get the kind of waistlines they want.
