Yes It can play a role in losing weight, but it doesn't really play a role in discharging oil. The main reason is that the oil displacement tablets contain orlistat, which can inhibit the absorption of fat in the intestine, so that the fat of food can only be excreted through feces, thus forming an oil displacement situation. If the intestine can't absorb fat, it can only consume its own fat, thus achieving the effect of losing weight. However, oil displacement tablets should not be abused and should be taken according to the doctor's advice.
