Xenical Diet Pills

      Xenical (Orlistat) was approved by the Food and Drug Administration (FDA) in April, 1999 as a medication for the treatment of obesity. Unlike the majority of other diet pills that work by suppressing appetite, Xenical acts within the gastrointestinal tract. For this reason, it exhibits fewer side effects than many other diet pills.

Xenical inhibits the absorption of fat by the intestines, by blocking the action of lipase in the digestive tract. Lipase is an enzyme that breaks down fat to enable the body to absorb it. Xenical can prevent the absorption of as much as 30% of dietary fat by the body. This unabsorbed fat is then eliminated in the stool. Many researchers believe that Xenical may also aid weight loss by inhibiting the desire to eat excessive amounts of fat.

Research has shown that, combined with exercise and a low fat diet, Xenical can be a safe and very effective weight loss tool for some obese individuals. Some side effects can occur, particularly frequent or oily bowel movements. These side effects generally decrease with decreased fat intake, and conversely, are made worse with greater fat intake.

Xenical, in blocking the absorption of fats by the body, can also block the absorption of some nutrients, such as fat-soluble vitamins (A, D, E and K) and beta carotene. Often, a multivitamin taken daily is recommended to those taking Xenical. The FDA recommends that vitamin supplements be taken 2 hours before or after taking a dose of Xenical.

Xenical and Obesity

Obesity has become increasingly prevalent in the U.S. over the past few decades. Research indicates that 1 in 4 Americans qualify as obese - having a Body Mass Index (BMI) of over 30. Over 56% of Americans are considered overweight (BMI 25-29.9) or obese.

Obesity increases the risks of many serious health conditions, such as high blood pressure, diabetes, stroke. osteoarthritis, coronary artery disease and some cancers. Many researchers believe that a 5-10% reduction in body weight of obese individuals greatly reduces the risk of developing many of the health conditions linked to obesity. Xenical offers a method to assist obese individuals to loose weight, helping the prevention of many obesity related illnesses.

Xenical is not intended as a long term solution to obesity. Xenical is intended to assist people to begin to loose weight, while at the same time making lifestyle changes, such as increased physical activity and better eating habits.
