Orlistat is a lipase inhibitor. That is why; it can reduce absorption of dietary fat because it is capable of inhibiting gastrointestinal lipase function.
The efficacy of Orlistat is modest. It is already scientifically confirmed. Data from clinical trials show:
1] Orlistat is capable of blocking absorption of 25 - 30% of fat in a diet supervised by doctors and reduce the calories consumed.
2] People who take Orlistat combined with diet and exercise, for 1 year, can lose 2-3 kilograms more than people not taking the drug.
Orlistat can result in some side effects, which may include unpleasant gastrointestinal events, associated with elimination. The side effects reduce after some time and they are considered as the only negative effects of the medicine.
You can minimize the effect of the side effects by reducing calories from fat in your diet to less than 30%.
Orlistat seems to be safe for long-term use. Some doctors think that Orlistat should only be used after being advised by a doctor because the medicine may be responsible for conditions like gallbladder problems, under-active thyroid, history of pancreatitis, diabetes, liver disease, and chronic malabsorption syndrome (nutrient absorption problems).
Doctors also think that the medicine should be used in combination with a doctor-supervised diet.
