    Black oil discharge after taking Orlistat is a side effect of the drug, and it does not rule out gastrointestinal bleeding. When using Orlistat, it can inhibit the absorption of fat in the intestines. It needs to be used under the guidance of a doctor. After abnormal stool occurs, you need to go to the hospital for examination to determine the specific cause.

    1. Drug side effects

    Some people who are obese or overweight will use orlistat. When taking orlistat, due to the side effects of the drug, oily spots and fecal incontinence will appear in the stool. After stopping taking the drug, the symptoms of physical discomfort will be relieved. This is a relatively common drug side effect. If the clinical symptoms are serious, you need to go to the hospital for examination and treatment immediately.;

    2. Gastrointestinal bleeding

    When abnormal stool occurs, it is best to go to the hospital for routine stool and occult blood tests, mainly to rule out the cause of gastrointestinal bleeding. If the test results show that it is gastrointestinal bleeding, the bleeding needs to be stopped under endoscopy, and balloon compression can be performed. There are certain contraindications when using drugs. If you want to take the drug Orlistat, you need to go to the hospital for examination and clarify the specific number of times to take the drug under the guidance of a doctor. People with severe chronic diseases or weak gastrointestinal systems should not take Orlistat, as they are prone to drug side effects.
