CVD is an umbrella term used to describe health problems that affect the heart and blood vessels. It is also known as heart disease. It includes conditions such as heart attacks and stroke.

CVD is on the increase. The number of people living with CVD nearly doubled between 1990 and 2019 and it is the leading cause of death and disability worldwide. Unfortunately, there is a proven link between obesity and CVD. Put simply, living with obesity can increase the risk of developing heart disease.

You may already be aware that obesity can lead to the development of high blood sugar and raised levels of blood pressure and cholesterol. However, you may not have realised that these are all significant risk factors for CVD – if left untreated, they can potentially cause heart disease.

Why? There are two key reasons. High levels of fat in the body (known as adiposity) is known to cause a wide-range of cardiovascular abnormalities, such as increased heart rate, and raised pressure on the arteries in the heart. These abnormalities can all increase the risk of a cardiovascular (CV) event.

The second factor is hardening of the arteries (atherosclerosis) caused by a build-up of fatty material in the blood vessels. This restricts blood flow and increases the risk of blood clots and stroke (where the blood supply to part of the brain is cut off).

The reality is that people living with overweight or obesity are at a greater risk of a CV event. On a more positive note, most people can reduce their risk by making changes to their lifestyle.

The good news is that making relatively small changes can help to reduce the risk of CVD. In fact, you may already be making some of these choices.

• Many people understand the importance of keeping track of blood pressure, cholesterol and blood sugar levels. Your doctor, nurse or pharmacist can arrange for you to be tested on a regular basis. If your levels are above normal limits you may be offered medication or advised to make lifestyle changes
• It is equally important to try and keep your weight within a healthy range. Even modest reductions in your weight can have a positive effect in terms of reducing the risk of CVD
• You should also aim to increase your level of activity. Find something that you enjoy – brisk walking, dancing or football are all beneficial!
• Quitting smoking is a healthy choice for everyone, as is keeping alcohol levels to within recommended limits

The sooner you start making changes, the better. The first step is to talk to your doctor.

The Waist to Height Ratio calculator is a useful tool to help assess whether action should be taken to manage weight. Input your height and waist circumference to see your result and what this means for you.

• Make a list of any questions and take notes during the appointment. Consider taking a friend or family member along for support
• Explain that you are aware of the link between obesity and heart disease and concerned that you may be at risk. Ask what specific steps you can take to reduce your risk
• If you are struggling to control your weight, explain that you need support
• Be honest. There is no point pretending that everything is OK if you are finding it difficult to cope
• If you do not understand something, say so! It is important to be clear about what you are being advised to do

Depending on your individual circumstances, your doctor may discuss a range of different strategies. These include:

• Regular monitoring of your cholesterol, blood pressure and blood sugar. Make sure you understand what the results mean
• Discussing lifestyle factors such as increasing levels of exercise, quitting smoking and reducing alcohol intake
• Reviewing eating habits and agreeing a plan of healthy eating
• Identifying and tackling behaviours that are preventing you from managing your weight. You may be referred to a specialist weight management provider or offered behavioural therapy
• Discussing weight loss medications if appropriate
• Discussing bariatric surgery (surgery to the gastric system) if appropriate

You don’t have to face this alone. Support is available.
