What causes coffee-colored spit in the morning?

Under normal circumstances, people rarely spit. Once they spit out coffee-colored sputum, it means that there is something wrong with some part of the body. The most common reasons are dust absorbed by the body, long-term smoking, respiratory or lung infection, chronic bronchitis, etc. Secondly, it is also related to the environment in which you live. It can be seen that if you want to determine the cause of coffee-colored sputum, you must be cautious, otherwise you will blindly treat it.

1. Certain foods and drinks can cause the color of sputum to turn brown. Although it may be a little concerning if the color appears darker than usual, it is generally not a threat. Eating chocolate, drinking red wine and dark cola can cause brown phlegm.

2. Dust can also cause brown sputum. When cleaning dusty rooms, handling sand or dust, small particles can enter the throat and become attached to mucus. The result is that the sputum coughed up becomes brown and contains particulate matter.

3. Smoking is also one of the most common causes of yellow-brown sputum. This usually happens when resins, tars and other toxic chemicals enter the lungs. Heavy smokers tend to cough up small amounts of brown phlegm in the morning.

4. People who try to quit smoking usually cough up a lot of brown phlegm. After you quit smoking, the lung cilia damaged by cigarettes begin to return to normal function. These tiny cilia help the lungs clear large amounts of phlegm. This process sometimes takes several months.

5. People who live in areas with severe air pollution may also cough up brown phlegm. Continued exposure to certain types of air pollution can also lead to chronic diseases, including bronchitis, emphysema and cancer.

6. Certain respiratory or lung infections are more serious causes of brown sputum. Coughing up phlegm is the body's natural mechanism for clearing excess mucus from the lungs. Often during a respiratory illness, the lungs begin to produce more mucus than usual to trap bacteria and other foreign matter.

7. Brown sputum is also a symptom of chronic bronchitis. People with lung cancer or other serious respiratory infections, such as emphysema, can also cough up brown phlegm. The specific cause needs to be confirmed by a doctor.
