Post-Meal Heart Rate Increases and Safety in Thrill Rides - Cardiology

Increased heart rate after meals?


Hello doctor, I would like to ask about something.
Sometimes after eating, my heart rate tends to be faster than usual (in the 80s to 90s), and occasionally it reaches around 100.
I have noticed this with my smartwatch.
Is this normal? Additionally, I would like to know if someone who experiences occasional skipped heartbeats can ride roller coasters and other thrilling attractions.
The frequency is not very high; in the past, I measured about 4 to 50 occurrences in a day.
Thank you.

Hello, an increase in abdominal pressure after a meal may cause your heart rate to be faster than usual, which is normal.
Don't worry if you experience around 40-50 missed beats in a day; this is also considered normal.
Stimulating activities should not have a significant impact.
Changhua Hospital cares about you.

More Info


Experiencing an increased heart rate after meals is a common phenomenon and can be attributed to several physiological factors. When you eat, your body directs more blood flow to the digestive system to aid in the digestion process. This increased demand for blood can lead to a temporary rise in heart rate, which is generally considered normal. For many individuals, a heart rate that rises to the 80s or 90s, and occasionally reaching 100 beats per minute after eating, is not unusual. This response can be more pronounced in individuals who may have underlying anxiety or panic disorders, as the anticipation of a rapid heart rate can exacerbate feelings of discomfort.

However, if you find that your heart rate consistently exceeds these levels or if you experience symptoms such as dizziness, shortness of breath, or chest pain, it would be prudent to consult with a healthcare professional. They can perform a thorough evaluation, including a physical examination and possibly an electrocardiogram (ECG), to rule out any underlying cardiac conditions.

Regarding your question about participating in thrill rides, such as roller coasters, if you have a history of heart palpitations or skipped beats (also known as ectopic beats), it is essential to approach this activity with caution. While many people with occasional palpitations can enjoy such rides without any issues, those with a known history of heart rhythm abnormalities should consult their cardiologist before engaging in high-intensity activities.

The concern with thrill rides is that they can induce significant physical stress on the body, including rapid changes in heart rate and blood pressure. For individuals with a history of heart rhythm issues, this could potentially trigger more frequent palpitations or even more serious arrhythmias in rare cases. If your palpitations are infrequent (4-50 times a day as you mentioned), and you have been evaluated by a healthcare provider who has deemed your heart health stable, you may be able to enjoy these rides. However, it is always best to err on the side of caution and discuss your specific situation with a healthcare professional who understands your medical history.

In summary, post-meal increases in heart rate are typically normal and can be influenced by various factors, including anxiety and the body's physiological response to digestion. If you have concerns about your heart rate or palpitations, especially in relation to engaging in activities like thrill rides, consulting with a healthcare provider is the best course of action. They can provide personalized advice based on your health status and help ensure that you can enjoy such activities safely.
