Living with diabetes can increase the risk of heart problems. This can feel worrying and it is completely understandable to be concerned about how this may affect your health or independence. You are not alone, and support is available.
Why diabetes affects the heart
High blood glucose, high cholesterol and high blood pressure can damage the blood vessels that supply the heart. Over time, these vessels can become narrow or blocked by fatty deposits. When blood flow to the heart is reduced or suddenly blocked, it can lead to a heart attack.
Early signs of a possible heart problem
Some people experience typical symptoms; others have more subtle signs. You may notice:
- chest pain, heaviness or pressure
- pain spreading to the arm, jaw, neck or back
- feeling breathless
- nausea, sweating or feeling faint
- new or unexplained tiredness
- swollen ankles or feet
- A fast or irregular heartbeat
Not everyone gets chest pain especially women, older adults and people with diabetes.
If you suspect a heart attack
A heart attack is a medical emergency. Call 999 and ask for an ambulance if you suspect a heart attack. A lack of blood to the heart may seriously damage the heart muscle and can be life threatening.

Reducing your risk
You can protect your heart by:
- keeping blood glucose, blood pressure and cholesterol at healthy levels
- being active in a way that works for you
- eating a balanced diet
- taking prescribed medications
- stopping smoking
- reducing salt
- keeping alcohol within safe limits
Your GP or diabetes team can support you in making changes that feel realistic and manageable.
