Description

Orlistat is a clinically approved weight loss medication designed for adults with a BMI of 28 or higher. It works in your digestive system by preventing around one-third of the fat from the food you eat from being absorbed. This undigested fat is then naturally passed out of the body, helping you reduce your calorie intake without affecting your appetite.

When combined with a reduced-calorie, lower-fat diet and an active lifestyle, Orlistat can significantly improve weight loss results over time. It’s taken three times a day with main meals containing fat. Common side effects may include changes in bowel movements, which usually settle as your body adapts.

Orlistat is suitable for patients looking for a non-hormonal, non-injectable weight loss solution with a long-standing safety profile.

Take one 120mg capsule with each main meal that contains fat—usually three times per day (breakfast, lunch, and dinner). Swallow the capsule whole with water, either just before, during, or up to one hour after the meal.

If a meal is missed or contains no fat, skip the dose.

For best results, follow a reduced-calorie, lower-fat diet and remain physically active. Avoid high-fat meals, as this can increase the likelihood of side effects.

Common side effects (usually mild and related to the digestive system):

  • Oily or fatty stools
  • Urgent or increased bowel movements
  • Flatulence with discharge
  • Abdominal cramps or discomfort
  • Oily spotting on underwear

These usually occur when eating meals high in fat. Sticking to a low-fat diet can help minimise side effects.

Less common side effects:

  • Headache
  • Fatigue
  • Irregular periods
  • Anxiety

Seek medical help if you experience signs of liver problems (e.g. yellowing skin/eyes) or severe abdominal pain.

Supports your weight loss through hormone regulation

Wegovy contains semaglutide, a GLP-1 medication that mimics a natural hormone involved in appetite and blood sugar control. It helps slow digestion, reduce cravings, and increase feelings of fullness—so you eat less, without constantly thinking about food. Backed by science and prescribed by experts, Wegovy works with your body to support long-term weight loss.

  • Helps reduce appetite and increase satiety
  • Slows digestion to reduce food intake
  • Improves blood sugar control 
(particularly for those with insulin resistance)

Timeline & Use

What to expect when using Orlistat
Orlistat begins working right away, but visible results develop gradually. Staying consistent with your capsules, diet, and activity is key.

  • Week 1

    You begin taking Orlistat three times a day with meals that contain fat. You may notice changes in your digestion as your body starts adjusting.
  • Week 2

    Side effects like oily stools or more frequent bowel movements may appear—these are signs Orlistat is working. Reducing fat intake can minimise them.
  • Week 3

    You’ll likely notice more control over food portions and fat-rich meals. If you're following a healthy plan, early weight loss may begin.
  • Week 4

    Your body is adjusting well. If side effects have eased, you’re likely tolerating the medication. Stick with a reduced-calorie, lower-fat diet.
  • Week 5+

    With consistent use, Orlistat helps block fat absorption and supports ongoing weight loss. Most people begin to see noticeable progress around this stage.

Every medication can cause side effects. You’ll receive full safety guidance and support before and during your treatment.
