Your brain is starving for blood

A stroke is a blockage of blood flow to an area of your brain. Deprived of oxygen, your brain cells in the area begin to die, and that means you begin to lose abilities – limb control, sight, speech, or even memory. A mini-stroke may only raise minor issues, such as temporary weakness of an arm or leg; while a major stroke can cause permanent damage or death. According to the World Health Organisation, strokes claim 6.3 million lives every year and that’s tragic, as a large percentage of strokes are preventable. Read on to learn how to reduce your stroke risk factors.

High blood pressure

Shazam Hussain, MD, director of the Cerebrovascular Center at Cleveland Clinic, says high blood pressure is the most significant preventable risk factor for stroke. “If blood pressure could be controlled … half of strokes would be eliminated,” says Dr. Hussain. High blood pressure wreaks havoc on your arteries. When they weaken or suffer damage, they can burst or clog more easily. That’s why doctors push patients to hit a healthy blood pressure number: “The newest guidelines recommend blood pressure be less than 130/80,” says Dr. Hussain. One way to lower your blood pressure is to limit salt intake to less than 1500 milligrams per day. Find out the 6 signs of a stroke you could be ignoring.

High cholesterol

Cholesterol in the arteries can block normal blood flow to the brain, causing a stroke. That’s one reason to watch your cholesterol. Ideal total cholesterol is 200. Once you hit 240, you’re at higher risk for stroke. It’s especially important to ask your doctor about your very low-density lipoprotein – VLDL – levels. High levels of VLDL cholesterol are associated with developing plaque deposits on artery walls, which can narrow the artery, restricting blood flow. “Eat a healthy diet; limiting the amounts of saturated fats and trans fats is very important,” says Dr. Hussain. “Due to the beneficial fats in fish, eating fish twice a week is recommended.” In addition, cut back on sugar and refined carbohydrates, as eating more of these than you burn can lead to excessive amounts of triglycerides and high levels of VLDL. Finally, daily exercise is also essential. Keep in close collaboration with your doctor in regards to medication and diet to lower cholesterol, Dr. Hussain says. Here’s how to act ‘FAST’ if you sense a stroke is coming.

Heart disease

“Many heart conditions increase the risk of having a stroke. In particular, a rhythm disturbance of the heart known as atrial fibrillation can substantially increase stroke risk,” says Dr. Hussain. You can control this stroke risk factor by asking your doctor about using blood thinners to reduce your risk. Other heart conditions linked to a build-up of plaque in the arteries can also increase stroke risk. Improve your odds by following a healthy diet, exercising, and potentially taking medication; be sure to follow your doctor’s recommendations and care.

Diabetes

Diabetes comes with increased risk of related health complications, including heart disease, kidney damage, nerve damage – and stroke. The chances of having a stroke for someone diagnosed with the condition are 1.5 times higher than in people who don’t have diabetes. But you can reduce your risk by keeping your blood sugar, blood pressure, and cholesterol levels in check. Eat a healthy diet that strictly limits sugar and refined carbohydrates, exercise daily, reduce stress, and keep up with your scheduled meds or insulin. And if you smoke, find a program to help you quit. Above all, don’t go it alone, advises Dr. Hussain: “Close collaboration with physicians with expertise in managing diabetes is important.” Discover how you can aid your recovery after a stroke with exercise.

Sickle cell disease

This inherited condition makes red blood cells that are misshapen and defective, so they can’t deliver sufficient oxygen to the rest of the body. The red blood cells may also clump together and clog up blood vessels in the brain; this can cause a stroke, even in children. Patients and their doctors can monitor the condition using a special ultrasound test called a transcranial Doppler, explains Dr. Hussain. “They may also need prophylactic transfusions,” he says. Including a stroke, here are 12 medical conditions that can kill you in 24 hours or less.

Heavy alcohol use

Some studies suggest a little bit of booze might be healthy, but there’s pushback when it comes to stroke, says Dr. Hussain. “While mild use of alcohol is controversial – newer studies suggest that even low amounts of alcohol can increase the risk of heart attack or stroke – it is certain that heavy alcohol use can substantially increase stroke risk,” warns Dr. Hussain. For women, that means more than a drink a day; for men, more than two will begin to raise stroke risk. (A drink is one shot of hard liquor, 100 ml of wine, or 285 ml full-strength beer.) If you have known stroke risk factors, it’s a good idea to reduce or eliminate alcohol. Find out if there’s room for alcohol in your diet if you have diabetes.

Diet drinks

A brand new study published in Stroke suggests that downing just one artificially sweetened drink a day nearly triples the risk of stroke. The researchers tracked the health of post-menopausal women – some of whom drank artificially sweetened beverages. Those who drank at least one artificially sweetened beverage daily had almost three times the risk of stroke or dementia compared to women who had artificially sweetened beverages less than once a week. “This study adds to the evidence that limiting the use of diet beverages is the most prudent thing to do for your health,” said Rachel K. Johnson, PhD, RD, a member of the American Heart Association’s science advisory committee on low-calorie sweetened drinks in a press release. Along with artificial sweetener, here are the foods that nutritionists won’t touch… and you shouldn’t either.

Smoking

You know that smoking is unhealthy, but did you realise how much it raises your risk of stroke? Smoking drives down levels of HDL cholesterol while raising LDL cholesterol, which when too high, can damage the cells that line blood vessel walls and make blood cells sticky and more likely to clot and block blood flow to the heart and brain. That’s a deadly combo, says Dr. Hussain: “Stopping smoking is critical in the prevention of stroke.” Check out 15 amazing ways your body heals itself after you quit smoking.

Obesity

“Obesity increases multiple risk factors, including high blood pressure, high cholesterol, and diabetes,” Dr. Hussain says. But what weight is considered obese? According to the Centers for Disease Control, a BMI of 30 or higher is in the obese range. You can easily determine your BMI using a calculator. The good news: Every little bit of weight you lose will drive down your stroke risk, says Dr. Hussain. Discover 37 fat-burning foods to help you lose weight.
