Have These Conditions? You Might Have a Stroke?
These five health conditions increase your risk of having a stroke.
A stroke happens when blood flow to a part of your brain is blocked or reduced, causing brain cells to die. This serious medical emergency can happen suddenly and without warning, but it is often linked to underlying health conditions that increase your chances of having a stroke. Understanding these conditions and managing them properly can significantly lower your stroke risk.
“Many strokes can be prevented by identifying and controlling risk factors early,” says Mark Farag MD, PIH Health neurologist. “Regular screenings and lifestyle modifications play a huge role in reducing stroke risk.”
Here are some common health conditions that may raise your stroke risk, as well as what you can do to lower your risk:
High Blood Pressure (Hypertension)
High blood pressure means the force of blood pushing against your artery walls is consistently too strong. Over time, this added pressure can damage arteries, making them stiff or weak. This damage increases the risk of clots forming or vessels bursting, either of which can lead to a stroke.
“High blood pressure is the single most important risk factor for stroke,” explains Dr. Farag. “Because it often has no symptoms, regular monitoring is essential. Even small reductions in blood pressure can significantly lower stroke risk.”
Diabetes
Diabetes affects how your body processes sugar, leading to high blood sugar levels. Over time, excess sugar damages blood vessels and nerves, making them more prone to blockages. Additionally, diabetes increases the likelihood of developing high blood pressure and high cholesterol, both of which raise stroke risk.
“People with diabetes have up to four times the risk of stroke compared to those without diabetes,” warns Dr. Farag. “Keeping blood sugar levels stable through diet, exercise, and medication is crucial in preventing long-term vascular complications, including stroke.”
High Cholesterol
Cholesterol is a fatty substance that your body needs in small amounts, but too much of it—especially LDL (“bad”) cholesterol—can build up in your arteries. These fatty deposits can narrow or block blood vessels, preventing normal blood flow to the brain. When a blockage occurs, it can cause an ischemic stroke, the most common type.
“Controlling cholesterol is key to preventing artery blockages,” says Dr. Farag. “A heart-healthy diet, regular exercise and, if necessary, cholesterol-lowering medications can help reduce the risk.”
Atrial Fibrillation (AFib)
AFib is an irregular heartbeat that causes blood to pool in the heart instead of flowing smoothly. When blood sits still for too long, clots can form. If a clot breaks free and travels to the brain, it can block blood flow, causing a stroke. People with AFib have a significantly higher risk of stroke, making it crucial to manage this condition with medication and lifestyle changes.
“AFib increases stroke risk by about five times,” notes Dr. Farag. “Fortunately, blood thinners and other treatments can greatly reduce this risk, making proper diagnosis and management essential.”
Obesity
Carrying excess weight puts extra stress on the heart and blood vessels, increasing the risk of high blood pressure, diabetes and high cholesterol. Each of these conditions independently raises the likelihood of stroke, and when combined, the risk becomes even greater.
“Weight management isn’t just about appearance—it’s a key part of stroke prevention,” says Dr. Farag. “Losing even a small amount of weight can improve overall cardiovascular health and significantly reduce stroke risk.”
How to Lower Your Stroke Risk
Identifying and managing these health conditions is key to preventing a stroke.
“Stroke prevention starts with awareness and action,” emphasizes Dr. Farag. “Regular check-ups, proper medication use and adopting a heart-healthy lifestyle can make a life-changing difference.”
Healthy habits such as eating a balanced diet, staying active, limiting alcohol intake, not smoking and maintaining a healthy weight can all help lower your risk. Making small but consistent changes can have a big impact on your long-term health and is one of the best ways to lower your stroke risk.
