Understanding Stroke

A stroke can be classified into two main types: ischemic stroke and hemorrhagic stroke.

Ischemic Stroke:

 This type of stroke occurs when a blood clot blocks a blood vessel supplying the brain. It is the most common type, accounting for around 80% of all strokes.

Hemorrhagic Stroke:

 This type of stroke occurs when a blood vessel in the brain ruptures or leaks, causing bleeding. Although less common, it is generally more severe and has a higher mortality rate.

Causes of Stroke

Several risk factors can increase the likelihood of experiencing a stroke:

High blood pressure:

 Uncontrolled hypertension is the leading cause of stroke. It damages blood vessels over time, making them more susceptible to blockages or ruptures.


Tobacco use increases the risk of stroke by damaging blood vessels and causing atherosclerosis.


 People with diabetes are more likely to have high blood pressure and high cholesterol, both of which increase the risk of stroke.


Being overweight or obese can lead to various health issues, including high blood pressure, diabetes, and high cholesterol, all of which increase the risk of stroke.

High cholesterol:

Elevated levels of cholesterol can cause the buildup of plaque in blood vessels, leading to blockages and increasing the risk of stroke.

Symptoms of Stroke

Recognizing the symptoms of stroke is crucial for seeking immediate medical attention. The most common warning signs include:

  • Sudden numbness or weakness in the face, arm, or leg, especially on one side of the body.
  • Difficulty speaking or understanding speech.
  • Sudden blurred vision or trouble seeing in one or both eyes.
  • Severe headache with no known cause.
  • Trouble walking, dizziness, or loss of balance and coordination.

Prevention of Stroke

While certain risk factors for stroke, such as age and family history, cannot be changed, there are several lifestyle modifications that can significantly reduce the risk of stroke:

Manage blood pressure:

 Regular monitoring and control of high blood pressure can greatly reduce the risk of stroke.

Quit smoking:

 It is essential to quit smoking or avoid exposure to secondhand smoke to prevent stroke and various other health complications.

Maintain a healthy weight:

Adopting a balanced diet and engaging in regular physical activity can help manage weight and reduce the risk of stroke.

Control diabetes:

 By managing diabetes through medication, a healthy diet, and regular exercise, the risk of stroke can be minimized.
