Weight management

Maintaining a healthy weight can improve your overall health and wellbeing. It can reduce the risk of developing conditions such as:

  • Type 2 diabetes
  • High blood pressure
  • Heart disease and stroke
  • Certain cancers
  • Sleep apnoea
  • Joint and back pain
  • Liver disease

Losing even a small amount of weight can have significant health benefits. A weight loss of 5-10% of your body weight may help improve blood pressure, cholesterol levels and blood sugar control.

What is Obesity?

Obesity is a complex long-term health condition that occurs when excess body fat affects health and wellbeing.

Body Mass Index (BMI) is often used as a guide to assess weight status. It compares your weight to your height:

  • Healthy weight: BMI 18.5-24.9
  • Overweight: BMI 25-29.9
  • Obesity: BMI 30 or above

BMI is not suitable for everyone and should be considered alongside other factors such as waist measurement, ethnicity, fitness level and overall health.

You can calculate your BMI using the NHS BMI calculator: https://www.nhs.uk/live-well/healthy-weight/bmi-calculator/


Causes of Weight Gain

Weight gain can occur for many reasons, including:

  • Eating more calories than your body uses
  • Lack of physical activity
  • Genetics and family history
  • Certain medical conditions
  • Some medications
  • Emotional wellbeing, stress, anxiety or depression
  • Poor sleep and shift work
  • Social and environmental factors

Obesity is not simply a matter of willpower. Many factors can influence body weight, and support is available.


Healthy Weight Management

The most effective approach to weight loss is making sustainable lifestyle changes.

Healthy Eating

Try to:

  • Eat regular meals
  • Include plenty of vegetables, fruit and wholegrains
  • Choose lean sources of protein
  • Reduce foods high in sugar, salt and saturated fat

Weight Loss Medication

Weight loss medications may be suitable for some people when combined with lifestyle changes.

Eligibility depends on factors including:

  • BMI
  • Weight-related health conditions
  • Previous weight management attempts
  • National and local NHS prescribing guidance

These medications are not suitable for everyone and require assessment by a healthcare professional.

Availability of Weight Loss Medication

Weight loss medications are currently only available on the NHS for a small number of patients who meet strict eligibility criteria set nationally and locally.

Our practice is only able to offer these medications to patients who meet these specific criteria. Due to the prescribing restrictions, most patients seeking support with weight management will continue to be offered lifestyle advice and referral to appropriate weight management services.

If you are eligible for NHS weight loss medication through our practice, we will contact you directly. There is no need to contact the surgery to request these medications unless you have been advised to do so by a healthcare professional.

For patients who do not meet the current eligibility criteria, we can discuss other options and sources of support to help you achieve and maintain a healthier weight.
