Orlistat is a widely used medication for weight management, helping people reduce fat absorption and achieve their weight loss goals. Available as both a prescription and an over-the-counter treatment, it has been proven effective when combined with a balanced diet and exercise. However, like any medication, Orlistat comes with potential side effects, which can be challenging if not managed properly.

At Pharmaesthetics Central, we provide expert guidance on weight loss tablets UK users can trust, ensuring safe and effective use of Orlistat. In this guide, we will discuss common side effects, why they occur, and how to manage them through dietary adjustments.

How Does Orlistat Work?

Orlistat works by blocking the absorption of dietary fat in the intestines. Around 30% of the fat consumed in a meal is prevented from being absorbed, allowing it to pass through the digestive system instead. While this helps reduce calorie intake, it also leads to some of the most well-known side effects of the medication.

Because Orlistat directly affects fat digestion, the most common side effects are digestive-related, occurring when too much fat is consumed while taking the medication.

Common Side Effects of Orlistat

1. Oily or Greasy Stools

One of the most frequent side effects is the presence of oily, orange-coloured stools. This occurs because undigested fat is excreted through bowel movements. While harmless, it can be inconvenient or embarrassing.

How to Manage It:

–> Stick to low-fat meals to reduce the amount of undigested fat passing through the system.

–> Spread your fat intake evenly throughout the day rather than consuming it all in one meal.

2. Increased Bowel Movements or Urgency

Some users report needing to visit the toilet more frequently or experiencing a sudden urge to go, sometimes leading to accidents if meals contain too much fat.

How to Manage It:

–> Monitor fat intake carefully, ensuring meals contain no more than 15g of fat per serving.

–> Gradually reduce fat intake to allow your digestive system to adjust to Orlistat.

3. Flatulence and Bloating

Excess fat in the digestive system can cause gas and bloating, leading to discomfort.

How to Manage It:

–> Limit high-fat foods such as fried items, full-fat dairy, and processed snacks.

–> Increase fibre intake with whole grains, fruits, and vegetables to aid digestion.

4. Loose Stools or Diarrhoea

Because Orlistat prevents fat absorption, consuming too much fat can lead to loose stools or diarrhoea.

How to Manage It:

–> Keep daily fat intake below 30% of total calories to prevent excessive fat elimination.

–> Eat smaller, balanced meals rather than large, high-fat meals.

–> Stay hydrated to replace lost fluids and prevent dehydration.

5. Mild Stomach Pain or Discomfort

Some users experience stomach cramps or discomfort, particularly in the first few weeks of taking Orlistat.

How to Manage It:

–> Stick to a healthy, balanced diet with lean proteins, whole grains, and low-fat dairy.

–> Avoid foods that are heavily processed or greasy, as they can irritate digestion further.

How to Adjust Your Diet While Taking Orlistat

A well-balanced diet is key to minimising Orlistat’s side effects while maximising its weight loss benefits. Here are some key dietary adjustments to consider:

1. Reduce Fat Intake

The more fat you consume, the higher the chance of digestive side effects. Aim for no more than 15g of fat per meal.

–> Swap full-fat dairy for low-fat or fat-free options.

–> Choose grilled, baked, or steamed foods instead of fried options.

–> Avoid buttery sauces, creamy dressings, and fried snacks.

2. Eat More Lean Proteins

Protein helps keep you full without causing digestive issues.

–> Opt for chicken, turkey, fish, eggs, tofu, and beans.

–> Avoid processed meats like sausages and salami, which contain hidden fats.

3. Increase Fibre Intake

Fibre supports digestion and helps reduce bloating or diarrhoea.

–> Eat plenty of vegetables, fruits, whole grains, and legumes.

–> Gradually increase fibre intake to avoid sudden bloating.

4. Stay Hydrated

Drinking enough water helps flush out excess fat and prevents dehydration from potential loose stools.

–> Aim for at least 8 glasses of water per day.

–> Limit caffeinated and sugary drinks, which can irritate digestion.

5. Plan Your Meals in Advance

Being mindful of your food choices can help you avoid unwanted side effects.

–> Prepare low-fat meals and portion them correctly.

–> Read nutrition labels carefully to check fat content.

–> Stick to fresh, home-cooked meals instead of takeaway or processed foods.
