When nasal discharge turns yellow, it’s a sign our immune system is fighting an infection. This color change often means there’s an underlying condition that needs attention.
The color change in nasal discharge is mainly due to our immune response. When we meet pathogens, our immune system makes more white blood cells. These cells have enzymes that can turn mucus yellow or green. Medical Expert, an ENT specialist, notes, “Yellow phlegm usually means the body is fighting an infection.”
“The color of nasal discharge can be an important indicator of the type and severity of the underlying infection.”
Distinguishing between bacterial and viral infections is key, as treatments differ. Viral infections are more common and often clear up on their own. Bacterial infections might need antibiotics. The color of nasal discharge can hint at the type of infection. For example, yellow watery liquid from the nose might suggest a viral infection.
Nasal discharge color can change as we fight off an illness. It usually goes from clear to yellow or green. This change is normal during recovery. But, if discharge stays yellow or green for 2 weeks, it might be a sign of a serious issue that needs medical help.
Understanding these changes helps us manage our illness better. Watching sinus temperature and other symptoms can also give us clues about how serious the condition is.
It’s important to know how sinusitis and upper respiratory infections lead to yellow phlegm. This knowledge helps in treating these conditions effectively.
Sinusitis is an inflammation or infection of the sinus passages. It can cause yellow phlegm. The NHS says sinusitis can be acute or chronic, often coming from a cold or flu. Acute sinusitis starts suddenly, while chronic sinusitis lasts longer.
Acute sinusitis comes after a viral infection and can last up to 4 weeks. Chronic sinusitis, lasting over 12 weeks, can be caused by allergies, anatomical issues, or infections.
| Characteristics | Acute Sinusitis | Chronic Sinusitis |
| Duration | Up to 4 weeks | More than 12 weeks |
| Causes | Viral infection, sometimes bacterial | Various, including allergies, anatomical issues |
| Symptoms | Nasal congestion, facial pain, yellow phlegm | Persistent nasal congestion, discharge, facial pain |
The common cold affects the upper respiratory tract. It can cause sinusitis and yellow or green mucus. As the cold gets worse, the mucus color and consistency change, showing the body’s fight against the infection.
“The common cold is a major cause of sinusitis, and understanding its progression can help in managing symptoms and preventing complications.”
NHS Guidelines
It can be hard to tell sinusitis from upper respiratory infections because of similar symptoms. But, yellow phlegm and facial pain or fever can help diagnose the issue.
