Poor health related to being overweight is a problem which is becoming ever more prominent in the UK. The NHS estimates that as many as one in four adults in this country are affected by obesity alone, as well as one in five children aged 10-11. While being overweight can cause low self-esteem and result in a reduced quality of life, it is also a catalyst for serious physical illnesses such as heart disease, diabetes, stroke and even some types of cancer.
Doctors determine whether someone is overweight by calculating their body mass index (or BMI). A person’s BMI is their weight in kilograms divided by their height in metres, and then this figure is divided by their height in metres again:
BMI = (weight in kg ÷ height in m) ÷ height in m
BMI can also be calculated using imperial measurements. This is done by taking a person’s weight in pounds, dividing this by their height in inches, dividing this sum by their height in inches again, and then multiplying the sum of this by 703:
BMI = ((weight in lbs ÷ height in inches) ÷ height in inches) x 703
People with a BMI between 20 and 25 are considered to be at their ideal weight; whereas those between 25 and 30 are classified as overweight; and those at 30 or above fall into the obese category.
A number of health and lifestyle factors can contribute to someone being unhealthily overweight. High calorie intake, lack of exercise and poor dietary habits can all play a part in causing someone to gain weight. Over time, this added mass can restrict the circulation of blood and oxygen around the body, and put extra strain on the body’s organs, leading to serious illness.
Treatment for those who are overweight or obese is usually issued in the form of a comprehensive weight loss programme. This might include a controlled and balanced diet, an exercise regime, motivational support, and sometimes weight loss medication.
Xenical, by Roche, is one of the most popular prescription drugs on the market for weight loss, and is also available as Orlistat, in its generic form. The active constituent in these medications works in the digestive tract. When we digest food, certain enzymes facilitate the absorption of fat into the body. These are called lipases, and help the digestive system to store fats as energy. By limiting the activity of these enzymes, Orlistat prevents fat from being assimilated into the body. Rather than being stored, the fat is then excreted in faeces.
Alli is another treatment containing orlistat which is used for weight loss. This contains half the dose of that found in Xenical and generic Orlistat, and is available in pharmacies over the counter. Before someone is able to buy Alli, they will still need to consult with a medical professional at the pharmacy, to make sure it is suitable for them. When you buy Alli from our online pharmacy, you will therefore still need to take our medical questionnaire.
Xenical and Orlistat reduce fat uptake from meals by around a third, while Alli reduces fat absorption by around a quarter.
Anti-obesity pills such as these can be useful for those with a BMI of 28 or above who are motivated to get their weight down to healthier levels. They are effective when used alongside a healthy diet and exercise plan.

Types of Treatment
There are three medications available for those who are obese or overweight here at Treated.com, and they are Alli, made by GSK, Xenical, made by Roche, and Orlistat. They are all tablet treatments which contain the same active ingredient, called orlistat, and work in the same way. Whereas Xenical is a branded drug, Orlistat is the generic version. Alli contains half the amount of the active ingredient (60mg) of the other two medications (120mg). Only those who have a BMI of 28 or above are suitable users.
How do they work?
Unlike other tablets which are assimilated into the body via the bloodstream, the agent orlistat performs its function in the gut. It works by restricting the activity of certain enzymes which extract fats from food, and absorb them into the body. Instead of being stored, these fats are then excreted in stool.
What are the side effects?
You should check the product page or patient information leaflet for specific details relating to side effects, but those more commonly associated with this type of medicine include abdominal pain, headache, or diarrhoea.
Can I take them with other medications?
Some pharmaceutical products may interact with this medicine, and are not recommended for use in conjunction with it. These include acarbose and ciclosporin. Tell your prescriber which, if any, other treatments you are currently using during consultation.

What’s the difference between the medications?
All three medications perform the same function. Orlistat and Xenical contain 120mg of the active ingredient and reduce fat uptake by approximately one third, while the non-prescription option, Alli, contains 60mg of the active ingredient and reduces fat uptake by roughly one quarter.
Should I take Xenical, Alli or Orlistat?
It depends partly on whether you prefer to use branded or generic medicines. Xenical is the original treatment made by the developer, Roche; whereas Orlistat is the same medicine, which is not branded, but is a cheaper alternative.
It also depends on your weight loss goals, and how much weight you intend to lose. Alli is not as strong as the prescription options, and may be preferable for those who want to lose pounds at a more gradual rate than they would using Xenical or Orlistat.
Your doctor will be able to help you select the appropriate treatment.
Are there different side effects?
The recorded side effects for Xenical and Orlistat may differ slightly, because they may not have been tested on the same group. However, as both medicines are the same, the risk of side effects will be very similar if not identical.
The risk of side effects for Alli, as it is not as potent as the other two options, will typically be lower.
