Guide To The Causes Of Black Phlegm

Heart Valve Disease

Heart valve disease can be very serious. Normally, the heart valves allow blood to flow through the lungs so it can get oxygen and get rid of carbon dioxide. Blood has to be pumped throughout the body and goes from the heart, through the lungs, and back to the heart. If the valves are not working properly, blood can back up in the lungs. One result of this can be congestive heart failure. And because there is now blood in the lungs, when individuals cough up phlegm or mucus, it can be colored with the blood. This can result in it being a number of different colors, including brown and black. If individuals have symptoms like fatigue, shortness of breath, swelling, or dizziness, they should see a doctor. When they listen to the patient's heart, they might be able to hear a heart murmur. If this happens, patients need to make sure they get treatment to manage or fix the condition, because if too much fluid builds up in the lungs and around the heart, it can be fatal.
