A Deep Dive into the Potential Causes of Stroke:

Oct 19, 2023 By Nancy Miller

Are you passionate about learning more on the topic of strokes? It's an important topic for everyone to be familiar with, considering how common strokes are – in fact, over 700,000 people suffer from a stroke each year! With that said, understanding the potential causes of this serious health issue is key to helping reduce your risk. In this blog post, we'll be taking a deep dive into the factors that research has suggested could lead to having a stroke. We'll break down what might put someone at higher risk so you can make informed decisions for yourself and those around you. Get ready - let's jump right in!

What is a Stroke?

Before we dive into the potential causes of stroke, let's take a moment to understand what a stroke actually is. A stroke occurs when there is an interruption of blood flow to the brain, resulting in damage to brain cells. This can happen either due to a blockage in a blood vessel (known as an ischemic stroke) or when a blood vessel bursts and leaks blood into the brain (known as a hemorrhagic stroke). The lack of oxygen and nutrient-rich blood causes the affected brain cells to die, leading to various symptoms such as weakness on one side of the body, difficulty speaking or understanding language, and vision problems. Strokes can be life-threatening and require immediate medical attention.

How does it Occur?

The root cause for most strokes is atherosclerosis, a condition in which plaque builds up inside the arteries. The plaque can rupture and create a blood clot that blocks or narrows an artery, leading to decreased blood flow and potentially causing a stroke. However, there are also other factors that have been identified as potential causes of stroke. Let's take a closer look at some of these potential causes and what you can do to lower your risk.

High Blood Pressure:

High blood pressure (or hypertension) is a well-known risk factor for stroke. When your blood pressure is consistently above normal levels, it puts a strain on your arteries, making them more likely to become damaged or clogged. To reduce your risk of having a stroke due to high blood pressure, it is important to monitor your blood pressure regularly and consult with a healthcare professional if you have consistently high readings. They may recommend lifestyle changes such as exercise, dietary changes, or medication to help lower your blood pressure.


Smoking has many negative effects on the body, one of which is increasing the risk of stroke. The chemicals in tobacco smoke can damage the lining of the blood vessels, making them more susceptible to plaque buildup and clot formation. Additionally, smoking also increases your heart rate and blood pressure, further increasing your risk for stroke. If you are a smoker, quitting can significantly decrease your chances of having a stroke.


People with diabetes have an increased risk of developing atherosclerosis, which as mentioned earlier, is a major cause of strokes. High levels of glucose in the blood can damage the lining of the arteries and increase the risk of plaque buildup. Managing your blood sugar levels through diet, exercise, and medication can help reduce this risk.

Lack of Physical Activity

Leading a sedentary lifestyle with little to no physical activity has been identified as a potential cause of stroke. Regular exercise helps to maintain a healthy weight, lower blood pressure, and improve overall cardiovascular health – all of which can significantly reduce your risk of having a stroke. It's never too late to start incorporating physical activity into your daily routine.

Unhealthy Diet

Eating foods high in saturated and trans fats, cholesterol, and sodium can contribute to the development of plaque in the arteries. A diet high in fruits, vegetables, whole grains, and lean protein sources, on the other hand, can help to keep your arteries healthy and reduce your risk of stroke. Making small changes to your eating habits can make a big difference in reducing your risk.

Risk Factors for stroke including age, lifestyle, and heredity:

While there are certain factors that can increase your risk of having a stroke, it's important to note that anyone can have one regardless of age, lifestyle, or heredity. However, understanding these potential risk factors can help you take steps towards prevention and early detection.


As we age, our risk for stroke increases. This is because the arteries in our bodies naturally become narrower and harder with age, making them more susceptible to damage and blockages. It's important to be aware of this risk and take steps towards a healthy lifestyle as we get older.


The choices we make in our daily lives can also impact our risk for stroke. As mentioned earlier, maintaining a healthy weight, exercising regularly, and following a balanced diet can significantly reduce our risk. Avoiding excessive alcohol consumption and not smoking are also important lifestyle factors to consider.


While you cannot control your genetics, having a family history of stroke may increase your chances of having one. If you have a close relative who has had a stroke, it's important to discuss this with your healthcare provider and take steps towards prevention and early detection.

Warning signs and symptoms of a stroke:

Recognizing the warning signs and symptoms of a stroke can help save lives. It's important to remember the acronym FAST when assessing for a stroke:

  • Face drooping: One side of the face may droop or feel numb. Ask the person to smile and see if one side is drooping.
  • Arm weakness: One arm may become weak or numb, making it difficult to raise or hold.
  • Speech difficulty: The person may have slurred speech or difficulty speaking and understanding language.
  • Time to call for help: If you notice any of these symptoms, call for emergency medical assistance immediately. Time is crucial when it comes to treating a stroke.

Dietary changes to reduce your risk of stroke:

In addition to incorporating regular physical activity into your routine, making dietary changes can also help reduce your risk of stroke. Here are some recommendations for a stroke-preventing diet:

  • Reduce sodium intake: Consuming too much sodium can lead to high blood pressure, which increases the risk of stroke. Aim to limit your daily sodium intake to no more than 2,300 milligrams.
  • Increase potassium intake: Foods high in potassium, such as bananas, spinach, and sweet potatoes, can help lower blood pressure and reduce your risk of stroke.
  • Limit cholesterol: High levels of cholesterol can contribute to the development of plaque in the arteries. Limiting your intake of saturated fats found in animal products and trans fats found in processed foods can help keep your cholesterol levels in check.


While there are certain factors that can increase your risk of having a stroke, it's important to remember that anyone can have one. However, by making lifestyle changes and being aware of warning signs and symptoms, we can reduce our risk and potentially save lives. It's important to prioritize our health and seek medical advice if we notice any concerning changes in our overall well-being. Let's take control of our health and work towards a future free from strokes.
