Cardiovascular disease (CVD) is a general term for conditions affecting the heart or blood vessels. It's usually associated with a build-up of fatty deposits inside the arteries (atherosclerosis) and an increased risk of blood clots. It can also be associated with damage to arteries in organs such as the brain, heart, kidneys and eyes. CVD is one of the main causes of death and disability in the UK, but it can often largely be prevented by leading a healthy lifestyle. There are many different types of CVD. 4 of the main types are described on this page. Coronary heart disease occurs when the flow of oxygen-rich blood to the heart muscle is blocked or reduced. This puts an increased strain on the heart, and can lead to: Read more about coronary heart
disease. A stroke is where the blood supply to part of the brain is cut off, which can cause brain damage and possibly death. A transient ischaemic attack (also called a TIA or "mini-stroke") is similar, but the blood flow to the brain is only temporarily disrupted. The main symptoms of a stroke or TIA can be remembered with the word FAST, which stands for: Read more about stroke and TIAs. Peripheral arterial diseasePeripheral arterial disease occurs when there's a blockage in the arteries to the limbs, usually the legs. This can cause:

This is the largest blood vessel in the body, which carries blood from the heart to the rest of the body. One of most common aortic diseases is an aortic aneurysm, where the aorta becomes weakened and bulges outwards. This doesn't usually have any symptoms, but there's a chance it could burst and cause life-threatening bleeding. Read more about aortic aneurysm. The exact cause of CVD isn't clear, but there are lots of things that can increase your risk of getting it. These are called "risk factors". The more risk factors you have, the greater your chances of developing CVD. If you're over 40, you'll be invited by your GP for an NHS Health Check every 5 years. Part of this check involves assessing your individual CVD risk and advising you how to reduce it if necessary. High blood pressureHigh blood pressure (hypertension) is one of the most important risk factors for CVD. If your blood pressure is too high, it can damage your blood vessels. Read more about high blood pressure. SmokingSmoking and other tobacco use is also a significant risk factor for CVD. The harmful substances in tobacco can damage and narrow your blood vessels. High cholesterolCholesterol is a fatty substance found in the blood. If you have high cholesterol, it can cause your blood vessels to narrow and increase your risk of developing a blood clot. Read more about high cholesterol. DiabetesDiabetes is a lifelong condition that causes your blood sugar level to become too high. High blood sugar levels can damage the blood vessels, making them more likely to become narrowed. Many people with type 2 diabetes are also overweight or obese, which is also a risk factor for CVD. InactivityIf you don't exercise regularly, it's more likely that you'll have high blood pressure, high cholesterol levels and be overweight. All of these are risk factors for CVD. Exercising regularly will help keep your heart healthy. When combined with a healthy diet, exercise can also help you maintain a healthy weight. Being overweight or obeseBeing overweight or obese increases your risk of developing diabetes and high blood pressure, both of which are risk factors for CVD. You're at an increased risk of CVD if:

Tell your doctor or nurse if you have a family history of CVD. They may suggest checking your blood pressure and cholesterol level. Ethnic backgroundIn the UK people of south Asian and Black African or African Caribbean background have an increased risk of getting CVD. This is because people from these backgrounds are more likely to have other risk factors for CVD, such as high blood pressure or type 2 diabetes. Other risk factorsOther factors that affect your risk of developing CVD include:
Types of CVDA healthy lifestyle can lower your risk of CVD. If you already have CVD, staying as healthy as possible can reduce the chances of it getting worse. Stop smokingIf you smoke, you should try to give up as soon as possible. The NHS Better Health website can provide information, support and advice to help. Your GP can also provide you with advice and support. They can also prescribe medication to help you quit. Read more about stopping smoking and stop smoking treatments. Have a balanced dietA healthy, balanced diet is recommended for a healthy heart. A balanced diet includes:
Read more about healthy eating. Exercise regularlyAdults are advised to do at least 150 minutes of moderate activity a week, such as cycling or brisk walking. If you find it difficult to do this, start at a level you feel comfortable with and gradually increase the duration and intensity of your activity as your fitness improves. Visit your GP for a health check if you haven't exercised before or you're returning to exercise after a long break. Read advice about starting exercise. Maintain a healthy weightIf you're overweight or obese, a combination of regular exercise and a healthy diet can help you lose weight. If you're struggling to lose weight, your GP or practice nurse can help you come up with a weight loss plan and recommend services in your area. Read more about losing weight and how your GP can help. Cut down on alcoholIf you drink alcohol, try not to exceed the recommended limit of 14 alcohol units a week for men and women. If you do drink this much, you should aim to spread your drinking over 3 days or more. A unit of alcohol is roughly equivalent to half a pint of normal-strength lager or a single measure (25ml) of spirits. A small glass of wine (125ml) is about 1.5 units. Your GP can give you help and advice if you're finding it difficult to cut down your drinking. MedicineIf you have a particularly high risk of developing CVD due to high blood cholesterol, your GP may recommend taking medicines called statins to reduce your risk. Page last reviewed: 22 April 2022 What are the factors affecting body composition?Gender, age, race, nutrition, physical activity, and hormonal status are the main determinants of body composition. Illness may have a significant effect on body composition; malnutrition is a major complication.
What are the 4 main parts of body composition?The 4-component (4C) model, which divides body weight into fat, water, mineral, and protein, can overcome these limitations.
Is body composition is best improved or maintained by participating in a running program?The science is clear that running improves your body composition, which in turn improves your performance. Running has been proven as an effective way to lose fat with minimal muscle loss when participants are properly nourished and allow their body ample rest and recovery.
What is a healthful body composition?For people aged 20 to 39, women should aim for 21% to 32% of body fat. Men should have 8% to 19%. For people 40 to 59, women should fall between 23% to 33% and men should fall around 11% to 21%. If you're aged 60 to 79, women should have 24% to 35% body fat and men should have 13% to 24%.
