Several infections can cause sputum production. Sputum is mucus that is coughed up from the lower airways (bronchi and lungs). Its presence often indicates an underlying respiratory condition. Below are some infections known to cause sputum:
Infections Leading to Sputum Production
| Infection | Description |
|---|---|
| Sinusitis | Inflammation of the sinuses, which can lead to postnasal drip and contribute to sputum. |
| Bronchitis | Inflammation of the bronchial tubes, causing coughing with mucus production. |
| Pneumonia | Infection of the lungs that causes inflammation and fluid or pus-filled air sacs. |
| Cystic Fibrosis | A genetic disorder that causes the body to produce thick and sticky mucus, often leading to chronic lung infections and sputum production. |
Other potential causes of sputum can include:
- Bacterial Infections: Bacteria like Streptococcus pneumoniae and Haemophilus influenzae are common culprits in respiratory infections.
- Viral Infections: Viruses such as the influenza virus, respiratory syncytial virus (RSV), and coronaviruses can cause increased mucus production.
- Fungal Infections: In certain populations (e.g., immunocompromised individuals), fungi like Aspergillus can cause lung infections with sputum production.
Sputum can vary in color and consistency, which can provide clues to the underlying infection. For example, green or yellow sputum often suggests a bacterial infection. It's important to consult a healthcare professional for proper diagnosis and treatment if you're experiencing persistent sputum production.
