Atrial fibrillation (Afib) is an irregular and often very rapid heart rhythm that can lead to blood clots in the heart and increase the risk of stroke, heart failure, and other heart-related complications. While the exact cause of Afib is unknown, problems with the hearts structure are the most common cause of Afib, including heart diseases and health problems such as high blood pressure, heart valve disease, and coronary artery disease. However, some people who have Afib have no known heart disease or heart damage, and it can sometimes affect people who are physically very fit, such as athletes.

Certain situations can trigger an episode of atrial fibrillation, including:

• Drinking excessive amounts of alcohol, particularly binge drinking
• Being overweight
• Excessive exercise
• Dehydration
• Stress
• Consuming large meals
• Sleep issues
• Caffeine
• Smoking
• Over-the-counter cough and cold medications
• Recreational drug use

Its important to note that not everyone with Afib will have the same triggers, and some people may not have any identifiable triggers at all. However, identifying and avoiding triggers can help control Afib and reduce the risk of complications.
