Rapid Heartbeat and Chest Discomfort After Gastroenteritis - Family Medicine

More Info

---

Hello! Thank you for your detailed question regarding your recent health issues following gastroenteritis. It sounds like you've been through quite a lot, and I appreciate your thoroughness in describing your symptoms. Let’s address your concerns one by one.

1. Increased Heart Rate: It is indeed possible for your heart rate to increase during an illness, especially one that involves fever and dehydration, such as gastroenteritis. When your body is fighting an infection, it can trigger a stress response, leading to an increase in heart rate (tachycardia). Additionally, dehydration from diarrhea can lead to lower blood volume, which can also cause your heart to pump faster to maintain adequate blood flow to your organs. A heart rate of 90 beats per minute is elevated compared to your usual resting rate of around 70, but it is not uncommon in the context of illness.
2. Chest Discomfort: The tightness and sharp pain in your left chest during deep breaths could be related to several factors. One possibility is that it could be musculoskeletal pain, which can occur after episodes of vomiting or coughing, or even from lying in one position for too long. Another possibility is that it could be related to anxiety, which can often accompany physical illness and can manifest as chest tightness or discomfort. However, since you have a history of valve insufficiency, it is important to monitor this symptom closely. If the pain persists, worsens, or is accompanied by other concerning symptoms (like shortness of breath or dizziness), you should seek medical attention promptly.

3. Follow-Up with Your Cardiologist: Given your history of valve insufficiency, it would be prudent to follow up with your cardiologist, especially if you are experiencing new or worsening symptoms. While gastroenteritis itself typically does not require antibiotics unless there is a bacterial infection, your cardiologist can assess whether your heart condition is contributing to your symptoms and whether any additional treatment is necessary.

In terms of managing your recovery from gastroenteritis, it’s essential to stay hydrated and gradually reintroduce foods that are easy on your stomach. Start with bland foods like bananas, rice, applesauce, and toast (the BRAT diet) and avoid spicy, fatty, or heavy foods until you feel better.
Additionally, if you continue to experience anxiety related to your health, consider discussing this with your healthcare provider, as they may recommend strategies or therapies to help manage your anxiety.

In summary, your increased heart rate is likely a response to your recent illness, and the chest discomfort could be related to several benign causes, but given your heart history, it’s wise to consult with your cardiologist. Keep monitoring your symptoms, stay hydrated, and take care of yourself during this recovery period. If you have any further questions or concerns, don’t hesitate to reach out to your healthcare provider. Wishing you a smooth recovery!
