Why It Feels Different and Why It Matters

Atrial fibrillation (Afib) doesn’t play favorites—it affects both men and women. But how it shows up, how it feels, and how it’s treated can be surprisingly different depending on your gender. If you or someone you love is living with Afib, understanding these differences can help you recognize symptoms sooner and get the right care faster.

Afib in Men: Often Silent, Sometimes Overlooked

Men are more likely to be diagnosed with Afib, but that doesn’t mean they always feel it. In fact, many men have what’s called “silent Afib”—they don’t notice symptoms until complications like stroke or heart failure occur.

Common symptoms in men may include:

• A racing or irregular heartbeat
• Fatigue or weakness
• Shortness of breath during activity
• Dizziness or lightheadedness

Symptoms can sometimes be subtle or ignored by men which may lead to a delay seeking care—sometimes until it’s too late. If you feel yourself thinking you’re just “getting old” suddenly, it could be Afib.

Afib in Women: More Symptoms, More Risk

Women with Afib often experience more noticeable symptoms—and more emotional distress. They’re also more likely to have other health conditions like high blood pressure or diabetes, which can make Afib harder to manage.

Women may report:

• Heart palpitations or fluttering
• Chest discomfort or pain
• Anxiety or a sense of dread
• Trouble sleeping
• Fatigue that feels overwhelming

Women are also at a higher risk of stroke from Afib than men, especially if they’re over the age of 75 or have other risk factors.

Why the Differences?

Hormones, heart size, and even how symptoms are described can all play a role. Women may be more likely to report symptoms, while men may underreport or ignore them. Unfortunately, this can lead to delays in diagnosis or differences in treatment.

When to Seek Medical Advice

No matter your gender, don’t ignore these signs:

• A fluttering, pounding or irregular heartbeat
• Shortness of breath, especially at rest
• Chest pain or pressure
• Dizziness or fainting
• Unexplained fatigue

If you notice any of these, call your doctor. Early diagnosis can prevent serious complications like stroke or heart failure.

Final Thoughts: Know Your Body, Speak Up

Afib doesn’t look the same for everyone. Whether you’re a man or a woman, your symptoms—and your experience—are valid. Don’t wait to speak up. The sooner you get help, the better your chances of living a healthy, active life.
If you’re a caregiver, encourage your loved one to talk to their doctor about any changes they notice. Your support can make all the difference.
