Orlistat is a weight management medicine that works by blocking the absorption of fat from your diet, making it easier to achieve weight loss.

Like all medicines, orlistat can cause side effects including headaches, abdominal pain, urgent, sudden or more frequent bowel motions, oily spotting, fatty or soft stools, low blood sugar levels, rectal pain, incontinence.

Not everybody experiences them, but if you do, they usually settle after a few weeks once you get used to the medication
