Don't Ignore the Warning Signs

Don't Ignore the Warning Signs


For some people, the irregular heartbeat of atrial fibrillation (AFib) never causes a problem. For others, it can lead to strokes and heart attacks or heart failure. Symptoms of AFib may include dizziness, fatigue, weakness, shortness of breath, and chest pain, especially when you have heart disease. If any of these concern you, or you feel your heart "skipping a beat" often, see your doctor.

Control Diabetes and Blood Pressure

People who have AFib are about five times more likely to have a stroke. Diabetes and high blood pressure raise that risk even more. 

Eat foods low in sugar and salt and watch your weight to lower your blood sugar and blood pressure -- and your risk of AFib complications.

Eat a Heart-Healthy Diet

Eat a Heart-Healthy Diet


At least half your plate should come from plants, such as leafy greens and colorful veggies and fruits. Add heart-healthy fats, like the omega-3 fatty acids in salmon. Good sources of protein include lean meats and legumes. Choose whole grains instead of refined carbohydrates for their fiber.

A diet low in refined sugars, trans fats, and sodium helps control your blood sugar, cholesterol, and blood pressure.

Quit Smoking

Quit Smoking


Put the cigarettes down for good to boost your odds of living a healthier life. Studies show that current and former smokers have a higher risk of developing AFib. Plus, smoking increases your risk of stroke.

Nicotine patches, gum, or lozenges may help. Medical treatment to stop smoking could double your chances of quitting successfully.

Take Care With Blood Thinners

Take Care With Blood Thinners


After you've been diagnosed with AFib, your doctor may prescribe blood thinners to lower your risk of stroke. These anticoagulant drugs can interact with some foods, supplements, or even other medications. Be sure to ask your doctor what's safe to eat, and what foods to avoid, while taking your medications.

Limit Alcohol and Stimulants

Limit Alcohol and Stimulants


A glass of wine at dinner is probably OK for most people with atrial fibrillation. But regularly drinking more than that and binge drinking are linked to heart rhythm problems, even for people with healthy hearts. 

Stimulants -- like decongestants with pseudoephedrine -- can also trigger your symptoms or make them worse. Check the labels on over-the-counter products, or ask your pharmacist.

Don't Overdo the Coffee

Don't Overdo the Coffee


In the past, some doctors told people with AFib never to drink coffee. But recent studies suggest caffeine isn't linked to more episodes. Drinking too much caffeine can raise your blood pressure, though. And that can be a trigger. Be mindful of how much coffee, tea, cola, and chocolate you have to keep you on an even keel.

Move Your Body

Move Your Body


Regular physical activity can help you lower your chance of complications from all kinds of heart disease. But intense exercise can sometimes bother your AFib. Start slowly if you're not used to it: Lace up your shoes and walk for half an hour every day.

Your doctor can help you figure out what kind of exercise is best and safe for you. 

Get Your Shots Early

Get Your Shots Early


People who get regular flu and pneumonia vaccines have a lower risk of heart attack. Be kind to your heart. Get your shots before flu season arrives.

Release Your Stress

Release Your Stress


Stress related to a specific event can trigger an irregular heartbeat. And ongoing stress often leads to unhealthy habits, such as smoking and heavy drinking -- both bad for your heart. 

Instead, try a meditative practice like yoga to help manage your tension and anxiety. One small research study found you may cut the number of AFib episodes you have in half.
