Does Wegovy Increase Heart Rate?

Wegovy contains the active substance semaglutide, a GLP-1 receptor agonist. GLP-1 receptors are found not only in the gut and brain but also in cardiac tissue, and stimulating them can have a mild chronotropic effect — meaning the heart may beat slightly faster. According to the electronic Medicines Compendium (eMC) product information for semaglutide, an increased heart rate is a recognised side effect of the medicine.

In practical terms, many people experience a rise of around a few beats per minute rather than a dramatic change, though individual responses vary. The effect tends to be most noticeable:

• In the first few weeks of starting Wegovy
• After a dose is increased as part of the prescriber-led titration schedule
• During physical activity, where a higher baseline can make exertion feel more intense

It is worth noting that this is not the same as a dangerous arrhythmia or heart condition — but any heart-related symptom that feels severe, persistent, or unusual should be discussed with a healthcare professional promptly. If you ever experience palpitations, chest pain, or a heart rate that feels significantly elevated or irregular, contact your prescriber or doctor without delay.

If you are curious about how a similar mechanism plays out with tirzepatide, the article on why Mounjaro can also affect heart rate covers this in more detail. You may also find it useful to read about how Wegovy can influence metabolism, since changes in metabolic rate and heart rate are often related topics for people on semaglutide. Other commonly reported effects — such as hair thinning on Wegovy — are part of the broader picture of how the body adapts during treatment.

One of the most useful things you can do when you notice a change like an elevated heart rate is to record it consistently, so you can see whether it follows a pattern — for example, whether it spikes after each dose and settles before the next, or whether it appears linked to sleep quality or activity levels.

GLP Trackr's side-effect tracker lets you log how you are feeling day by day, including symptoms like an elevated pulse, palpitations, or fatigue. Over time, the app surfaces patterns in your own data that can be genuinely useful to bring to a prescriber appointment. Instead of trying to recall how you felt three weeks ago, you have a clear, dated record. The daily check-in feature also captures energy levels and mood alongside any physical symptoms, giving a fuller picture of how your body is responding to treatment.

For a broader understanding of how GLP-1 medicines work in the body, the guide to how GLP-1 receptor agonists work provides helpful context.

GLP Trackr is a tracking and journaling companion — it is not a substitute for clinical advice, and any concern about your heart rate or cardiovascular health should always be discussed with your prescriber or doctor. They know your full history and are best placed to assess whether what you are experiencing is expected or needs attention. If symptoms feel severe or worrying at any point, contact a healthcare professional promptly rather than waiting for your next appointment.

Log your symptoms, spot your patterns, and go into every prescriber conversation better prepared. GLP Trackr is available free on the App Store and Google Play — start a 7-day free trial and see how it fits your journey.
