Fatigue: Mitral Valve Prolapse and Its Impact on Daily Life - Cardiology

More Info

---

Mitral Valve Prolapse (MVP) is a condition where the mitral valve, which separates the left atrium from the left ventricle of the heart, does not close properly. This can lead to mitral regurgitation, where blood leaks backward into the left atrium when the left ventricle contracts. MVP is often benign, but in some cases, it can lead to symptoms such as fatigue, palpitations, chest pain, and even anxiety.

Your symptoms of fatigue, shortness of breath, and dizziness, especially during physical activities like walking or climbing stairs, can indeed be related to your MVP and the associated mitral regurgitation. When the heart is not functioning optimally due to the valve not closing properly, it can lead to decreased cardiac output, which may manifest as fatigue and exertional dyspnea (shortness of breath during activity). The fact that you feel worse in the early morning hours could be linked to several factors, including changes in blood pressure, heart rate, or even hormonal fluctuations that occur during sleep.

Additionally, the medication you mentioned, likely a beta-blocker or similar heart medication, can have side effects that include fatigue and dizziness. These medications are often prescribed to help manage symptoms associated with MVP and to reduce the workload on the heart. If you are experiencing significant fatigue or other concerning symptoms, it is essential to discuss these with your healthcare provider. They may consider adjusting your medication or exploring other potential causes of your symptoms.

Your mention of not having your menstrual period and experiencing insomnia could indicate a possible hormonal imbalance or stress-related issues, which can also contribute to fatigue and exacerbate feelings of anxiety or discomfort. The autonomic nervous system, which regulates involuntary bodily functions, can be affected by stress, leading to symptoms such as palpitations, dizziness, and fatigue.
In summary, your fatigue and symptoms could be multifactorial, involving your mitral valve condition, the effects of medication, and possibly autonomic nervous system dysregulation. It is crucial to have a thorough evaluation by your healthcare provider, who may recommend further tests such as an echocardiogram to assess the severity of your mitral regurgitation, or possibly a Holter monitor to evaluate your heart rhythm over a 24-hour period.
In the meantime, consider lifestyle modifications such as pacing your activities, ensuring adequate hydration, and managing stress through relaxation techniques or counseling. If your symptoms worsen or you experience new symptoms, seek medical attention promptly. Your health and well-being are paramount, and addressing these concerns with your healthcare provider will help you find the best path forward.
