Unveiling the Silent Culprits: Common Causes of Strokes
Stroke is the disruption in blood flow to the brain. It is often referred to as "brain attacks," which is devastating and can be life-altering in most cases. This occurs when the blood supply to the brain is interrupted, leading to a lack of oxygen and nutrients that are vital for brain function.
While strokes can happen suddenly and without warning, there are often underlying factors that contribute to their occurrences. Strokes are a life-threatening emergency, and immediate medical attention is needed to prevent lasting damage or eventual death.
For this reason, people are advised to call their local emergency numbers for immediate attention because every second counts. In Ghana for instance, you should call the 112 or 193 for ambulance service or practically drive the patient to the nearest medical facility.
Generally, there are three (3) main types of strokes in patients.
Ischemic stroke, which occurs when the brain's blood vessels become narrowed or blocked, causing severely reduced blood flow (ischemia). The blockage of the arteries is caused by fatty deposits that build up in blood vessels and travel through the bloodstream to lodge in the brain’s blood vessels.
The other type is Hemorrhagic stroke. It is observed when a blood vessel in the brain leaks or ruptures. Trauma and uncontrollable high blood pressure are some of the causes for the leakage.
A Transient Ischemic Attack commonly called TIA is a less severe form of stroke. A TIA is caused by a temporary decrease of supply of blood to parts of the brain, which could last within a period of five (5) minutes
There are several common causes and risk factors associated with strokes, some of which can be managed or modified to reduce the risk to our health.
- High Blood Pressure is a silent assassin
One of the leading causes of strokes is high blood pressure, also known as hypertension. This silent killer often gets unnoticed, as it rarely presents with identifiable symptoms. However, the constant strain on the blood vessels can weaken them over time, increasing the risk of a stroke. Monitoring blood pressure regularly and adopting a healthy lifestyle that includes a balanced diet and regular exercise can help keep this silent culprit at bay.
- The hazard of smoking
It is well-documented that smoking, creates a myriad of health hazards, but its connection to stroke is often overlooked. The chemical components in cigarettes (nicotine, tar, ammonia, toluene, etc.) can damage blood vessels, making them more vulnerable to clots or ruptures.
Additionally, smoking can raise blood pressure and reduce the amount of oxygen in the blood, further increasing the risk of a stroke. It is never too late to quit smoking which will not only improve one’s overall health but also significantly reduce the chances of experiencing it.
- Intake of unhealthy diet
Our diet plays a crucial role in our overall health, and strokes are no exception. Consuming a diet high in saturated fats, cholesterol, and sodium can lead to the buildup of plaque in the arteries, narrowing them and restricting blood flow to the brain.
In other words, diets high in saturated fats, salt, and processed foods can contribute to hypertension, high cholesterol, and obesity, which are all stroke risk factors. Opting for a diet rich in fruits, vegetables, whole grains, and lean proteins can help reduce the risk of strokes by keeping our arteries clear and healthy.
- Sedentary lifestyle
In our world today, many of us spend a significant proportion of the time sitting, whether it is at our desks or in front of the screens. However, leading a lifestyle with little to no activity can have severe consequences, including an increased risk of stroke. The lack of physical activity can lead to various health issues, including hypertension and obesity, posing the likelihood of stroke.
It is hence recommended for individuals to engage in regular physical activities to help improve cardiovascular health, strengthen blood vessels, as well as reduce the potential of blood clots. Incorporating exercise into our daily routines can be as simple as taking a walk, cycling, or participating in a favorite sport.
- Excessive alcohol consumption
While moderate alcohol consumption may have some health benefits generally, the alcoholism can be damaging to our well-being. Heavy intake of alcohol has the potential to raise one’s blood pressure, causing irregular heart rhythms, and increase the likelihood of blood clot formation. To minimize the risk of strokes, it's essential to drink alcohol in moderation or consider abstaining altogether.
Conclusion
It's essential to recognize and manage these risk factors to reduce the chances of developing a stroke condition. Lifestyle modifications, such as regular exercise, a balanced diet, not smoking, limiting alcohol intake, and controlling blood pressure and cholesterol levels, can significantly help in stroke prevention. If you have concerns about your stroke risk, it's crucial to consult with a healthcare professional for personalized advice and appropriate management.
