Sep 25, 2024 Weight Loss

What is Orlistat?

Orlistat is a medication that is prescribed to help individuals lose weight. It does so by stopping some of the fat you ingest from being absorbed into the body. This can help you to lose weight when used alongside a suitable, healthy and balanced diet, and exercise plan.

How does Orlistat work?

Orlistat works by reducing the absorption of fat from your food. Fat that is not broken down can’t be absorbed by the body which means fewer calories are taken on board. The excess fat is removed from your body when you go to the toilet.

How Long After Taking Orlistat Do You Poop?

It usually takes 24hrs to 48 hrs for the Orlistat to start changing your bowel habits. Don’t be concerned if you find yourself going to the toilet more often than usual or experiencing a change in stool consistency. This is normal when taking Orlistat.

What Happens if You Take Orlistat Without Eating?

As with all medications, it is important to follow the instructions in the patient advice leaflet and those of your GP.  Orlistat is usually taken with main meals or within an hour of eating. Taking it on an empty stomach means it won’t work very well and you could experience side effects such as increased flatulence, discomfort, oily stools and more.

How Long Does Orlistat Take to Work?

Orlistat usually starts working within the first few days of taking it. Noticeable weight loss can take longer, from weeks or even months.  It is important to use Orlistat as prescribed, consistently and alongside an appropriate diet and activity plan. General results should mean you lose 5% of your body weight in the first 12 weeks. 

How Much Weight Loss Can Be Expected in a Week With Orlistat?

How much weight an individual loses when taking Orlistat depends on their specific circumstances, diet and more. On average, individuals taking Orlistat as instructed could lose 1-2 pounds a week. This is when used alongside a healthy, low-calorie diet. General results should mean you lose 5% of your body weight in the first 12 weeks. 

How To Get the Best Results from Orlistat?

Taking Orlistat as prescribed and following an appropriate low-calorie diet is the best way to boost the weight loss results. Again, a healthy diet and increased activity levels are key factors.

When to Take Orlistat?

Orlistat is usually taken with or within an hour of a main meal. If you miss a meal you don’t need to take that dose of Orlistat. Always follow your prescriber’s recommendations and the information in the Patient Information Leaflet that comes with the medication.

How Long Does Orlistat Stay in Your System?

Orlistat usually works its way out of your system 1-2 days after being taken. If you continue taking Orlistat you’ll continue to experience the bowel changes until you stop and the medication has had time to fully leave the boy.

What Happens if You Take 2 Orlistat?

It is not recommended to take more Orlistat than is prescribed. This may increase any side effects you might have but won’t increase your weight loss. Please follow medication dosage instructions fully.

How Long Can You Take Orlistat For?

How long you might take Orlistat depends on your specific circumstances, such as your weight loss goals and your BMI as you need to have lost 5% of your body weight in the first 12 weeks of treatment. If you are unsure how long you should take Orlistat or are experiencing any issues, please see your GP. 

How Safe is Orlistat?

Orlistat is considered safe to use, however, with all medications, there is a risk of side effects. Common side effects include flatulence, oily stools, abdominal pain/discomfort and more. These side effects tend to ease off once your body gets used to the Orlistat but for many might remain. If you are worried about side effects please see your GP.

How Much Weight Can You Lose With Orlistat?

How much weight someone might lose while taking Orlistat depends on the individual taking it, their starting weight, their activity levels and their diet. When following the instructions fully, many would be likely to lose 1-2lb a week. This is a good and sustainable amount to lose weekly.
