Recent research has suggested that there may be a strong link between weight and heart rhythm.

A study published in The Lancet Diabetes & Endocrinology journal in 2018 found that individuals who were overweight or obese had a higher risk of developing an irregular heartbeat, known as atrial fibrillation (AFib).

What is Atrial Fibrillation?

Atrial Fibrillation is a condition that affects the heart’s rhythm. It is caused when the electrical signals that coordinate the heartbeats are not working properly.

This can cause the heart to beat irregularly and can lead to symptoms such as palpitations, fatigue, and shortness of breath. In more severe cases, AFib can lead to stroke or heart failure.

How Does Weight Affect Heart Rhythm?

Research has shown that being overweight or obese can increase an individual’s risk of developing atrial fibrillation. One study found that individuals who were obese had a 49% higher risk of developing AFib compared to those with a healthy weight.

Other factors, such as high blood pressure and diabetes, which are more common in those who are overweight or obese, can also increase the risk of developing AFib.

The Impact of Weight Loss on Heart Rhythm

The good news is that weight loss can have a positive impact on heart rhythm.

A study published in the Journal of the American College of Cardiology found that weight loss, particularly through bariatric surgery, resulted in a significant improvement in AFib symptoms. Another study found that moderate weight loss in individuals with AFib resulted in a reduction in AFib episodes.

Other Lifestyle Changes to Improve Heart Health

In addition to weight loss, there are other lifestyle changes that can improve heart health and reduce the risk of developing AFib. These include:.

Quitting smoking
Maintaining a healthy diet
Exercising regularly
Managing stress

The Role of Medical Treatment

If an individual has developed AFib, medical treatment may be necessary. There are several medications used to manage AFib, such as blood thinners and heart rate control medications.

Additionally, procedures such as cardioversion and ablation can be performed to restore normal heart rhythm.

Conclusion

There is a clear link between weight and heart rhythm, with obesity increasing the risk of developing AFib.

However, lifestyle changes such as weight loss, quitting smoking, and exercising regularly can help to improve heart health and reduce the risk of developing AFib. If an individual has developed AFib, medical treatment may be necessary to restore normal heart rhythm.
