Cardiac issues
Hello Doctor, I am 26 years old and my phlegm has always been clear but has a lot of small bubbles on top.
Is this normal? I looked it up online and found some scary information 😭 but I've always had it this way.
I also have mitral valve prolapse with regurgitation; could this be related? My saliva also has many bubbles, and occasionally I experience nasal congestion and a dry throat.
Here is the response from the pulmonologist:
"Hello Abby, if the phlegm is colorless and transparent, there shouldn't be much to worry about.
Bubbly phlegm can indeed be a sign of heart failure, but if you do not experience any chest tightness or shortness of breath, the likelihood of severe heart failure is low.
If you are still concerned, you can seek evaluation from a cardiologist.
However, I have regular echocardiograms every year for my mitral valve prolapse with regurgitation, and the doctors have said there are no major issues.
The first year, I also had a 24-hour Holter monitor and an exercise test, both of which were normal.
So, is there still a significant connection between my bubbly phlegm and heart failure? I am really worried 😭."

It is recommended that you visit a cardiology outpatient clinic to determine if any relevant tests are needed.
Thank you, and wish you good health!

When it comes to understanding the presence of clear phlegm with bubbles, especially in the context of your medical history that includes mitral valve prolapse and regurgitation, it is essential to consider several factors. First, let's clarify what the presence of clear phlegm with bubbles might indicate.
Clear phlegm is generally considered normal, especially if it is not accompanied by other concerning symptoms such as significant chest pain, shortness of breath, or a persistent cough. The bubbles in your phlegm can be attributed to various benign causes, including the presence of air trapped in the mucus, which can occur due to the way the mucus is produced or expelled. This is not uncommon and can happen for many individuals without any underlying pathology.
However, you mentioned that you have a history of mitral valve prolapse with regurgitation. Mitral valve prolapse (MVP) is a condition where the valve between the heart's left atrium and left ventricle does not close properly, which can lead to mitral regurgitation. While MVP is often benign and many individuals live without significant complications, it can sometimes be associated with other cardiovascular issues, including arrhythmias or, in rare cases, heart failure.
The concern regarding the presence of bubbly phlegm is that it can sometimes be a sign of pulmonary edema, which is fluid accumulation in the lungs often associated with heart failure. However, as your physician pointed out, if you are not experiencing symptoms such as chest tightness, difficulty breathing, or significant fatigue, the likelihood of having severe heart failure is low. Regular follow-ups with your cardiologist, including echocardiograms and Holter monitoring, are crucial in managing your condition and ensuring that any changes in your heart function are promptly addressed.
It's also worth noting that other factors can contribute to the production of phlegm, such as allergies, environmental irritants, or even respiratory infections. If you occasionally experience nasal congestion and a dry throat, these symptoms could be related to allergies or dry air rather than a direct consequence of your heart condition.
In summary, while the presence of clear phlegm with bubbles can be concerning, especially for someone with a history of heart issues, it is not necessarily indicative of a severe problem if you are asymptomatic. It is always best to maintain open communication with your healthcare provider, especially if you notice any changes in your symptoms or if your anxiety about your health increases. If you continue to feel worried, consider scheduling an appointment with your cardiologist for a thorough evaluation. They can provide reassurance and possibly conduct additional tests if deemed necessary. Remember, managing your health involves not just monitoring physical symptoms but also addressing any emotional concerns you may have regarding your condition.
