Both orlistat and Besunyen have certain weight loss effects, but the weight loss principle and safety are different:

Orlistat is a lipase inhibitor and belongs to western medicine. Reduce weight mainly by inhibiting fat absorption. Orlistat can lose weight faster, but it may cause side effects such as diarrhea, so it is not recommended to use it for a long time.

Besunyen mainly contains some Chinese herbal medicines, such as cassia seed and lotus leaf, which can promote intestinal peristalsis and help defecation, thus achieving the effect of losing weight. Besunyen is a traditional Chinese medicine, which is relatively safe, but long-term use is not recommended.

The most scientific and effective way to lose weight is to control diet and combine effective exercise. If you need medication, please use it under the guidance of a doctor.
