How does too much weight affect the body?

Carrying too much weight puts stress on your body which can lead to a variety of health issues.

By reducing the amount of fat cells in your body, you reduce the likelihood of getting very serious conditions such as heart disease, certain cancers, stroke, liver disease, type II diabetes and high blood pressure. As fatty deposits within the circulatory system restrict blood flow, many overweight men suffer from erectile dysfunction. It also affects the respiratory system, with side effects such as sleep apnoea and asthma.

If you are overweight or clinically obese then you may suffer from low self-esteem or lack self-confidence and therefore losing weight can help you to regain confidence, increase your self-esteem and lower the risk of depression.  It also helps improve the ratio of good to bad cholesterol; reduce blood pressure and inhibit the progression to type II diabetes.

Weight loss can be a difficult and daunting prospect, however clinical studies have shown that those who use Xenical / Orlistat alongside dieting are much more likely to lose weight.

What is BMI?

BMI stands for 'Body Mass Index' and is a calculation made based on your height and weight.

Using the metric system, the formula is your weight in kilograms divided by your height in metres squared. That is weight kg/(height in metres)2 .

The BMI of an adult weighing 70kg and a height of 1.7m would be 70/(1.7)2 = 24.2 We can calculate your BMI for you if you put your height and weight ,in either metric or imperial figures, into our calculator on the Xenical / Orlistat medical questionnaire.

It is the marker for judging how much body fat you have and indicates whether you are overweight. People with a higher percentage of body fat tend to have a higher BMI, except for bodybuilders.

Carrying excess body fat, means that you are at increased risk of suffering health problems such as heart disease, stroke, diabetes and cancer. The normal BMI range for a healthy adult is 18.5 to 24.9 and anything more than this indicates that you are overweight.
