It says there are three main risk factors for stroke you can avoid through a healthy diet, which are high blood cholesterol, high blood pressure and excess body weight.
The main stroke symptoms include changes to the face. Your face may have dropped on one side, the person may not be able to smile, or their mouth or eye may have drooped.
Signs may also occur on the arms – “the person may not be able to lift both arms and keep them there because of weakness or numbness in one arm”, says the NHS.
Their speech may be slurred or garbled, “or the person may not be able to talk at all despite appearing to be awake” and “they may also have problems understanding what you’re saying to them”, adds the health body.
