Expect more frequent bowel movements, often with oily or fatty stools. This is a common side effect due to alli’s mechanism of action. The increased frequency usually isn’t excessive, but you might need to adjust your bathroom routine.
Changes in stool consistency are normal. You may experience looser stools than usual. This is a direct result of undigested fat passing through your system. Increased water intake can help manage this.
Don’t be alarmed by changes in stool volume. You may find you have slightly more stool than before starting alli. This is related to the increased fat excretion.
Gas and bloating are possible. These are temporary digestive discomforts that often decrease as your body adjusts to the medication. Reducing your fat intake can mitigate these symptoms.
If you experience severe abdominal pain, persistent diarrhea, or rectal bleeding, stop taking alli and consult your doctor immediately. These are unusual and require medical attention.
