Atherosclerosis

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:

  • you have chest pain that comes and goes
  • you feel short of breath
  • you have pain in your arms and legs when walking or exercising

You can call 111 or get help from 111 online.
