A stroke is a serious medical emergency that occurs when blood flow to a part of the brain is suddenly interrupted. This may happen due to a blockage in a blood vessel (ischemic stroke) or due to rupture of a weakened blood vessel causing bleeding in the brain (hemorrhagic stroke).When brain cells are deprived of oxygen and nutrients, they begin to get damaged within minutes. Immediate medical attention can save brain function — and even life.
Some risk factors for stroke cannot be changed, but many can be controlled with proper medical care and healthy lifestyle choices. The major modifiable risk factors include long-standing high blood pressure (hypertension), diabetes, smoking, excessive alcohol consumption, physical inactivity, obesity, and high cholesterol levels. Managing these conditions through regular check-ups, medication compliance, exercise, and a balanced diet can significantly reduce the risk of stroke.
There are also non-modifiable risk factors that cannot be altered. These include increasing age, gender, family history of stroke, existing heart disease, and a previous history of stroke. While these factors cannot be changed, being aware of them allows individuals to take preventive measures early and seek timely medical advice. Adopting a healthy lifestyle plays a crucial role in lowering overall stroke risk.
