• ✔ Healthcare assessment available to check suitability

A Weight Management Medicine That Works Differently

Losing weight can be challenging, particularly when lifestyle changes alone have not provided the progress you hoped for. Weight is influenced by many factors, including eating habits, activity levels, genetics, hormones and overall health.

Orlistat is a weight management medicine that works in a different way from many newer appetite-focused treatments. Instead of affecting hunger signals, Orlistat reduces the amount of fat your body absorbs from the food you eat.

When taken alongside a reduced-calorie, lower-fat healthy diet, a regular exercise routine and regular physical activity, Orlistat may help some adults achieve weight loss and develop healthier long-term habits.

At NuMe, we understand that choosing a weight management treatment is a personal decision. Every person has different health needs, treatment goals and circumstances. Our approach focuses on providing clear information and helping you understand whether Orlistat may be a suitable option for you.

Before treatment is supplied, a healthcare professional will review your information to check that the medicine is appropriate based on your BMI, medical history and any other medicines you take.

Meet Orlistat

Orlistat is a prescription and pharmacy medicine used to support weight management in adults who meet the appropriate eligibility criteria.

According to NHS guidance, Xenical Orlistat refers to the 120 mg prescription version sold under the brand name Xenical, while a lower-strength 60 mg pharmacy version (Alli) is available for eligible adults.

The active ingredient in both versions is Orlistat.

Orlistat belongs to a group of medicines known as lipase inhibitors. Lipases are enzymes in the digestive system that help break down fat from food so it can be absorbed by the body.

Orlistat works by blocking some of these enzymes. As a result, around one third of the fat from meals may pass through the digestive system without being absorbed.

Because it works on dietary fat rather than appetite, it is used to support weight loss when combined with a balanced, lower-fat eating plan.

How Orlistat Fits Into Everyday Life

Orlistat is taken with main meals that contain fat. This means your eating habits play an important role during treatment.

Some people find that taking Orlistat encourages them to become more aware of the types and amounts of fat they eat. This may support healthier food choices over time.

However, Orlistat does not burn existing fat, so a balanced diet, sustainable habits, and making time to exercise regularly still matter for long-term weight management.

Who Is Orlistat Intended For?

Orlistat may be considered for adults who are living with overweight or obesity, including obese patients, and meet the relevant treatment criteria.

For prescription treatment, Orlistat is generally considered for people with:

• A Body Mass Index (BMI) of 30 or above, or
• A BMI of 28 or above with weight-related health conditions, such as high blood pressure.

For the lower-dose pharmacy version, adults must meet the required eligibility criteria, including being aged 18 or older and having a BMI of 28 or above.

A healthcare professional will assess whether Orlistat is appropriate for you. Factors such as your medical history, current medicines and previous weight management attempts will be considered.

Not everyone who meets the BMI criteria will necessarily be suitable for Orlistat.

Clinical Evidence

Around one third

Research published in the journal Diabetes, Metabolic Syndrome and Obesity: Targets and Therapy found that Orlistat, when combined with lifestyle changes, supported greater weight loss and improvements in weight-related metabolic outcomes compared with lifestyle changes alone in adults living with overweight or obesity.

The amount of weight lost varies between individuals and depends on factors including diet, activity levels, treatment consistency and personal health circumstances.

Clinical Trial Results

Research into Orlistat has shown that adults taking the medicine alongside a reduced-calorie diet may achieve greater weight loss compared with those following dietary changes alone.

Clinical studies have also found that maintaining a lower-fat eating pattern can improve tolerance of treatment and may reduce some digestive side effects.

Individual results cannot be predicted, and not everyone will experience the same outcomes.

What Is Orlistat?

Orlistat is a medicine designed to support weight management by reducing the absorption of fat from meals.

Unlike medicines that affect appetite hormones, Orlistat works locally in the digestive system.

When you eat food containing fat, your body normally uses digestive enzymes called lipases to break the fat down so it can be absorbed.

Orlistat blocks some of these enzymes, meaning less fat from your food is absorbed. The unabsorbed fat then leaves the body naturally through bowel movements.

Orlistat May Help By:

• Supporting weight loss with a weight loss medication when combined with a reduced-calorie diet.
• Encouraging awareness of dietary fat intake.
• Helping some adults maintain healthier eating habits.
• Supporting longer-term weight management goals.

In the UK, Orlistat is the only weight loss pill approved by the NHS.

UK Availability

Orlistat is available in the UK in different strengths depending on the treatment route, including orlistat tablets.

Prescription Orlistat 120 mg may be supplied as prescribed orlistat by a doctor or another qualified healthcare professional following assessment, when appropriate.

Lower-dose Orlistat 60 mg may be available from pharmacies for adults who meet the eligibility requirements.

Before taking Orlistat, it is important to receive appropriate advice to help keep orlistat safe and make sure the medicine is suitable for your individual circumstances.

Orlistat Compared With Other Weight Management Medicines

Each weight management medicine works differently. The most suitable option depends on your health, medical history, treatment preferences and the advice of a healthcare professional.

Your Orlistat Treatment Pathway

Starting a weight management medicine is an individual decision that should be supported by appropriate healthcare advice. Orlistat works differently from many other weight management medicines, so understanding how to take it correctly and what to expect can help you use it safely.

Before starting treatment, your healthcare professional will assess whether Orlistat is suitable based on your BMI, medical history, current medicines and overall health.

Starting Orlistat Treatment

If Orlistat is considered suitable, treatment begins alongside a calorie controlled diet that is lower in fat.

The medicine is designed to work with your meals, meaning your eating pattern is an important part of your treatment plan.

Before you start, you should understand:

• How to take each dose correctly.
• Which meals require a capsule.
• How dietary fat affects side effects.
• What symptoms to look out for.
• When to seek medical advice.

A healthcare professional may also discuss realistic weight management goals and how your progress will be monitored.

How Orlistat Works During Treatment

Orlistat does not directly reduce hunger. Instead, it affects how your body processes dietary fat.

When you eat a meal containing fat, digestive enzymes called lipases normally break the fat down so it can be absorbed.

Orlistat blocks some of these enzymes, reducing the amount of fat absorbed from your food.

The remaining unabsorbed fat passes through your digestive system and leaves your body naturally. This undigested fat is what can contribute to bowel-related side effects.

Because the medicine affects dietary fat, eating too much fat may increase digestive side effects, which is why following a balanced, lower-fat diet is an important part of treatment.

Monitoring Your Progress

Weight management treatment should include regular reviews to check whether the medicine is helping and whether it remains appropriate.

Your healthcare professional may review:

• Changes in your weight.
• Your eating habits.
• How well you tolerate treatment.
• Any side effects.
• Your overall health.
• Other medicines you are taking.

Treatment decisions are based on your individual progress rather than a standard timeline that applies to everyone.

Reviewing Results After 12 Weeks

Orlistat treatment is usually reviewed after 12 weeks.

If you have not lost at least 5% of your initial body weight after this period, your healthcare professional may recommend stopping treatment.

This review helps ensure that you continue with a treatment approach that is appropriate and beneficial for your circumstances.

Realistic Expectations With Orlistat

Everyone responds differently to weight management treatment.

Some people may experience noticeable weight changes while taking Orlistat, while others may see more modest changes, so exactly how much weight you lose can vary from person to person.

The results achieved during treatment can depend on:

• The foods you eat.
• The amount of fat in your diet.
• Your activity levels.
• Your starting weight.
• Your overall health.
• How consistently you take the medicine.

Clinical studies provide information about average outcomes, but they cannot predict exactly how an individual person will respond.

The aim of treatment is to support healthier long-term weight management throughout your weight loss journey rather than encourage rapid or unrealistic weight loss.

Why Lifestyle Changes Still Matter

Orlistat is designed to support lifestyle changes, not replace them.

Long-term weight management usually involves a combination of healthier eating patterns, regular activity and sustainable daily habits.

Healthy Eating

A balanced diet remains an important part of treatment.

Because Orlistat reduces fat absorption, many people benefit from following a low fat diet with meals that contain moderate amounts of healthy fats while avoiding excessive amounts of high-fat foods. Each meal should contain around 30% fat.

Examples of healthier choices may include:

• Plenty of vegetables and fruit.
• Wholegrain carbohydrates.
• Lean sources of protein.
• Lower-fat dairy options.
• Healthy sources of unsaturated fats in appropriate portions.

It also helps to avoid high-fat foods like fried food and biscuits. Snacking between meals is generally not recommended while taking Orlistat.

A healthcare professional or dietitian can provide personalised advice if needed.

Physical Activity

Regular physical activity can support overall health and complement weight management efforts by helping your body use existing fat as part of a wider weight management plan.

You do not need to start with intense exercise. Building movement into your daily routine can be a practical way to become more active.

Examples include:

• Walking.
• Swimming.
• Cycling.
• Strength exercises.
• Active hobbies.

The right level of activity depends on your current health and fitness level.

Sleep and Weight Management

Sleep is an important part of overall wellbeing.

Poor sleep may affect energy levels, appetite and food choices. Developing a consistent sleep routine may support healthier habits alongside your treatment.

Staying Hydrated

Drinking enough water helps support normal body functions.

Good hydration is especially important if you experience digestive side effects such as changes in bowel movements.

Building Sustainable Habits

Successful weight management is often based on realistic changes that can be maintained over time.

Some calorie-controlled plans aim to reduce intake by around 600 calories, if advised by a clinician.

Small improvements to eating patterns, activity levels and daily routines can become valuable parts of your long-term health plan and help support a healthy weight after treatment through sustainable habits.

Overview of Orlistat Treatment

Orlistat is a weight management medicine that supports weight loss by reducing the absorption of dietary fat.

Unlike appetite-regulating medicines, it does not work by changing hunger signals. Instead, it works in the digestive system to limit how much fat from food enters the body.

A typical treatment journey includes:

1. Suitability Assessment

A healthcare professional reviews your BMI, health history and medicines to determine whether Orlistat may be appropriate.

2. Starting Treatment

You begin taking Orlistat alongside a reduced-calorie, lower-fat diet.

3. Adjusting Your Eating Habits

Understanding how much fat is in your meals can help reduce side effects and support treatment, and checking food labels is a practical way to see how much fat a meal contains.

4. Monitoring Progress

Your weight, side effects and overall response are reviewed.

5. Continuing or Reviewing Treatment

If treatment is helping and remains suitable, your healthcare professional may advise continuing. If sufficient progress has not been achieved, orlistat may be reviewed and an alternative weight loss treatment may be recommended.

Pharmacist Assessment and Support

When accessing Orlistat through a pharmacy or online healthcare provider, an assessment helps ensure that this prescription weight loss medication is appropriate and safe.

Your healthcare professional may review:

• Your BMI.
• Your age.
• Existing medical conditions.
• Current medicines.
• Previous weight management attempts.
• Any reasons why Orlistat may not be suitable.

This personalised approach helps ensure that medicine is supplied responsibly and that patients receive appropriate guidance.

At NuMe, we focus on helping patients understand their options and make informed decisions about their healthcare.

Directions for Use

Orlistat should always be taken exactly as directed by your healthcare professional or according to the instructions provided with your medicine.

Taking Orlistat correctly is important because the medicine works by blocking the absorption of dietary fat from the meals you eat.

When to Take Orlistat

The usual dose of Orlistat is one 120mg capsule three times a day with water immediately before, during, or up to one hour after each main meal that contains fat.

This means:

• Take one capsule with breakfast, lunch or dinner if the meal contains fat.
• If a meal is missed, the dose should be omitted.
• If a meal is a fat-free meal or contains no fat, the dose can also be omitted.

Do not take more capsules than recommended. Taking extra doses will not increase weight loss and may increase the risk of side effects.

Following a Lower-Fat Diet

Orlistat works best when combined with a balanced, low calorie diet that contains an appropriate amount of fat.

Eating a high fat meal, especially a very high fat meal, may increase digestive side effects, including oily stools and urgent bowel movements.

Many people find that taking Orlistat encourages them to become more aware of the fat content in their meals and make healthier food choices. Fruit and vegetables are good examples of foods that fit better within this recommended eating pattern.

Vitamins and Nutrients

Because Orlistat reduces the absorption of dietary fat, it may also affect the absorption of some fat-soluble vitamins, including vitamins A, D, E and K.

Your healthcare professional may advise whether a multivitamin supplement is appropriate, particularly if you are taking Orlistat over a longer period.

If a supplement is recommended, it is usually taken at a different time from your Orlistat dose. Follow the advice provided by your healthcare professional.

Missed Dose

If you forget to take Orlistat with a meal, do not take the missed capsule later unless it is still within the recommended timeframe stated in the medicine instructions.

Do not take an additional capsule with your next meal to make up for a missed dose.

If you regularly forget doses, speak with your healthcare professional for advice.

Storage

Store Orlistat according to the instructions provided with your medicine.

Keep capsules:

• In their original packaging.
• Away from moisture and excessive heat.
• Out of the sight and reach of children.

Always check the expiry date before taking your medicine.

How Long Should You Take Orlistat?

The length of treatment depends on your individual progress and whether the medicine continues to be suitable for you.

Treatment is usually reviewed after 12 weeks.

If you have not lost at least 5% of your initial body weight during this period, your healthcare professional may advise stopping treatment.

Regular reviews help ensure that you continue using a treatment approach that is appropriate for your health needs.

Why an Online Consultation Is Required

Orlistat may not be suitable for everyone, which is why an appropriate healthcare assessment is important before starting treatment.

An online consultation allows a qualified healthcare professional to review your health information and decide whether Orlistat may be a suitable option.

Supporting Patient Safety

Although Orlistat is available in some lower-dose pharmacy formulations, it is still important to check that it is appropriate for your circumstances.

Certain medical conditions, medicines or previous health problems, such as chronic malabsorption syndrome, may affect whether Orlistat should be used.

A consultation helps identify any factors that may require additional advice or an alternative treatment approach.

Reviewing Your Eligibility

Your healthcare professional may consider which weight loss treatments are suitable based on:

• Your BMI.
• Your age.
• Any weight-related health conditions.
• Your medical history.
• Your current medicines.
• Any previous weight management treatments.
• Your dietary habits.

For pharmacy supply of 60 mg Orlistat, eligibility generally includes being aged 18 or over and having a BMI of 28 or above.

Prescription-strength 120 mg Orlistat may be considered for adults who meet the relevant prescribing criteria.

Checking Medicine Interactions

It is important to tell your healthcare professional about all medicines and supplements you take.

Orlistat may affect the absorption of certain medicines, and additional advice may be needed if you take medicines such as:

• Blood-thinning medicines.
• Medicines for diabetes.
• Thyroid medicines.
• The contraceptive pill.
• Certain medicines that require consistent absorption.

The same advice may apply to the combined pill if severe diarrhoea or digestive upset occurs.

Your healthcare professional can advise whether any changes or additional monitoring are needed.

Personalised Support

A consultation is not only about checking eligibility. It also provides an opportunity to discuss:

• How Orlistat works.
• What side effects to expect.
• How to adjust your diet.
• How progress will be monitored.

At NuMe, we aim to provide clear information so patients understand their treatment options and can make informed healthcare decisions.

Is Orlistat Right for You?

Orlistat may be suitable for adults who meet the appropriate eligibility criteria and who have been assessed by a healthcare professional.

The medicine is generally considered for adults who are living with obesity or are overweight with additional weight-related health concerns.

Orlistat May Be Suitable If You:

• Have a BMI that meets the relevant treatment criteria.
• Are committed to making healthy lifestyle changes.
• Understand that the medicine works by reducing fat absorption.
• Are willing to follow a lower-fat eating plan.
• Are able to take the medicine correctly with suitable meals.

Orlistat May Not Be Suitable If You:

Orlistat is not appropriate for everyone.

It may not be suitable if you:

• Have certain digestive conditions affecting food absorption.
• Have problems with bile flow.
• Are allergic to orlistat or any ingredient in the medicine.
• Are pregnant or breastfeeding unless advised otherwise by a healthcare professional.
• Have other medical circumstances where treatment is not recommended.

Your healthcare professional will review your circumstances before treatment is supplied.

Possible Side Effects

Like all medicines, Orlistat can cause side effects, although not everyone experiences them.

Because Orlistat is known to work by reducing fat absorption, many side effects are related to changes in bowel movements. These effects are often linked to the amount of fat in your diet.

Following a lower-fat eating plan may help reduce digestive side effects.

Common Side Effects

The most common side effects are related to the digestive system.

These may include:

• Fatty or oily stools.
• Increased urgency to use the toilet.
• Loose stools.
• Wind with discharge.
• Increased bowel movements.
• Oily spotting.
• Stomach discomfort.

These effects are sometimes called steatorrhoea, which means excess fat in the stools.

They are usually more noticeable when eating meals that contain a higher amount of fat.

Many people find that symptoms improve as they become more familiar with the medicine and adjust their diet. For many people, side effects usually diminish after a few weeks.

Less Common Side Effects

Some people may experience:

• Abdominal pain or stomach pain.
• Bloating.
• Changes in bowel habits.
• Tiredness.
• Headache.
• Anxiety or changes in mood.

If side effects are persistent, troublesome or affecting your daily life, speak with your healthcare professional.

Serious Side Effects

Serious side effects are uncommon, but you should seek medical advice if you experience symptoms that concern you.

Speak to a healthcare professional promptly if you experience:

• Symptoms of a serious allergic reaction.
• Severe or persistent abdominal pain.
• Yellowing of the skin or eyes.
• Unusual changes that may indicate a liver problem.
• Signs of kidney problems.

Always read the patient information leaflet supplied with your medicine for a complete list of possible side effects and when to seek medical advice.

Managing Side Effects

Many Orlistat-related digestive effects are linked to dietary fat intake.

Practical steps that may help include:

• Keeping meals balanced and lower in fat.
• Avoiding very high-fat meals.
• Eating regular meals.
• Drinking enough water.
• Following the guidance provided by your healthcare professional.

If side effects continue despite dietary changes, seek advice before stopping treatment.

Who Can Benefit?

Orlistat may be considered for adults who meet the relevant eligibility criteria and who are looking for additional support with weight management alongside lifestyle changes.

People living with overweight or obesity may experience challenges with weight management due to a combination of factors, including appetite, lifestyle, genetics, medical conditions and environmental influences.

For some eligible adults, Orlistat may provide additional support by reducing the amount of dietary fat absorbed from food.

Following a healthcare assessment, Orlistat may be suitable for adults who:

• Have a BMI of 30 or above.
• Have a BMI of 28 or above with weight-related health conditions.
• Are prepared to follow a reduced-calorie, lower-fat eating plan.
• Understand that the medicine works alongside lifestyle changes.
• Are able to take the medicine correctly with meals containing fat.
• Want a weight management option that works differently from appetite-regulating medicines.

Every person's situation is different. A healthcare professional will consider your individual circumstances before recommending treatment.

Potential Health Benefits

When used appropriately alongside healthy lifestyle changes, Orlistat may support weight management for some eligible adults.

The benefits experienced will vary between individuals and depend on factors such as diet, physical activity, consistency with treatment and overall health.

Supporting Weight Loss

Orlistat is one of the prescription or pharmacy weight loss pills available for eligible adults, and it may help some people lose weight by reducing the amount of dietary fat absorbed by the body.

Clinical evidence suggests that this diet pill, when taken alongside a reduced-calorie diet, may support greater weight loss than lifestyle changes alone.

The amount of weight lost differs between individuals, and results cannot be guaranteed.

Encouraging Healthier Eating Habits

Because Orlistat affects how the body processes dietary fat, many people become more aware of the fat content and calorie intake in their meals while taking the medicine.

This awareness may help some people develop healthier eating patterns that continue beyond treatment.

Supporting Long-Term Weight Management Goals

Weight management involves more than reaching a particular number on the scales.

Developing sustainable habits around food, movement, sleep and wellbeing may help support long-term health.

Orlistat can be one part of a wider weight management approach that includes ongoing lifestyle changes and healthcare support. Keeping those habits in place after treatment ends may help reduce the risk of weight regain.

Supporting Weight-Related Health Goals

For some people, managing weight may support improvements in health markers linked with excess weight.

However, the effect of weight loss on health varies depending on individual circumstances, existing medical conditions and lifestyle factors.

Your healthcare professional can discuss realistic expectations based on your personal health profile.
