Atherosclerosis is where your arteries become narrowed, making it difficult for blood to flow through them. It increases your risk of heart attack and stroke.

Lifestyle changes, like stopping smoking, eating healthily and exercising regularly, can help stop atherosclerosis getting worse.

You may not have any symptoms of atherosclerosis, but symptoms can include:

• chest pain
• pain in your arms and legs, especially when exercising
• feeling short of breath
• feeling tired all the time
• feeling weak
• feeling confused

If you're over 40 you can get a free NHS health check which can spot the early signs of heart disease and stroke, as well as kidney disease, dementia and type 2 diabetes.

Ask for an urgent GP appointment or get help from NHS 111 if:

Atherosclerosis happens when fatty deposits build up in the arteries, which causes them to narrow.

Things that increase your chances of getting atherosclerosis include:

• being over 65 years of age
• smoking
• having high cholesterol
• having high blood pressure
• having close relatives who have cardiovascular disease

There are some things you can do to help stop atherosclerosis getting worse:

There are currently no treatments to reverse atherosclerosis, but you may be offered medicines to lower your risk of having a heart attack or a stroke.

You may need medicines to:

• lower your cholesterol (statins)
• lower your blood pressure
• lower your risk of blood clots
• lower your blood sugar levels if you have diabetes

You may also need surgery to help improve blood flow through the affected arteries.

Without lifestyle changes and medical treatment, atherosclerosis may get worse over time.

It can cause:

• heart attacks
• stroke
• peripheral arterial disease
• other types of cardiovascular disease
