Semaglutide can cause changes in heart rate, including palpitations and increased pulse.

Knowing the balance between side effects and serious heart issues empowers patients to manage their health confidently.
Semaglutide is a medication widely used to manage type 2 diabetes and support weight loss. It works by mimicking a hormone called GLP-1, which helps regulate blood sugar levels and appetite. While semaglutide has proven benefits, it can also affect the cardiovascular system, particularly the heart rate.
Many patients report experiencing palpitations or an increased pulse after starting semaglutide. These sensations can feel like your heart is racing, fluttering, or pounding unusually. It’s important to understand why this happens and when these symptoms should prompt a visit to a healthcare professional.
GLP-1 receptor agonists like semaglutide may increase heart rate by stimulating the sympathetic nervous system, which controls the body's 'fight or flight' response. This effect can lead to a mild elevation in resting heart rate, typically by 2 to 4 beats per minute. For most people, this change is not harmful, but it can feel noticeable.
Clinical studies have documented this increase in heart rate as a common side effect. The long-term impact on heart health is still being researched. Some evidence suggests semaglutide may offer cardiovascular benefits, such as reducing the risk of heart attack and stroke in people with diabetes, but individual reactions vary.
The relationship between semaglutide and heart health is a complex one. While the medication can increase heart rate, it has also been associated with weight loss, a significant factor in improving cardiovascular health. Excess weight is a known risk factor for heart disease, and by helping patients lose weight, semaglutide may indirectly contribute to better heart health outcomes. The medication has been shown to improve other cardiovascular risk factors, such as lowering blood pressure and improving lipid profiles, thereby further mitigating potential heart-related issues.
Patients considering semaglutide should engage in open discussions with their healthcare providers about their individual health profiles and any pre-existing conditions. This dialogue is crucial, especially for those with a history of heart disease or arrhythmias, as personalized medical advice can help manage any potential risks associated with the medication. Monitoring heart rate and overall cardiovascular health during treatment can provide valuable insights into how semaglutide is affecting the body and help ensure that the benefits outweigh any side effects experienced.
Palpitations are sensations where you feel your heart beating irregularly, too fast, or too hard. They can be brief or last several minutes. When caused by semaglutide, palpitations often occur shortly after starting the medication or increasing the dose.
Common triggers include anxiety, dehydration, caffeine, or other medications, so it’s helpful to consider these factors alongside semaglutide use.
A mild increase in pulse rate is expected with semaglutide. Your pulse may rise slightly but should remain steady and not cause discomfort. If your heart rate climbs above 100 beats per minute at rest or you feel dizzy, faint, or short of breath, these symptoms warrant further evaluation.
Tracking your pulse regularly can help you notice patterns or sudden changes. Use a simple wrist monitor or smartphone app to keep an eye on your heart rate, especially during the first few weeks of treatment.
Persistent palpitations lasting more than a few minutes
Chest pain or tightness
Shortness of breath or difficulty breathing
Dizziness, lightheadedness, or fainting spells
Rapid heart rate exceeding 100 beats per minute at rest
