Dear Tinus
Theoretically the use of Xenical which requires you to eat a very-low-fat diet will also lower cholesterol. The medication on its own does not really lower cholesterol per se as is the case with anti-cholesterol medications like statins, but because Xenical makes all the fat you eat pass straight out of the body it would also eliminate the cholesterol you eat. The very-low-fat diet will also not contain much cholesterol, so this will lower your cholesterol intake considerably. Then there is the effect of weight loss which also lowers cholesterol. However, if you have high cholesterol that does not respond to dietary manipulations then Xenical as such will not lower your blood levels. Discuss these aspects with your prescribing dr, who will advise if you need to take a statin in addition to the Xenical and the very-low-fat diet.
