Have you ever noticed a salty taste in your phlegm when you cough it up? If so, you’re not alone. Phlegm is a thick, mucus-like substance that is produced by the mucous membranes in the respiratory tract. It functions to protect the airways from dust, bacteria, and other foreign particles. In some cases, phlegm may take on a salty taste or contain salty mucus.
The salty taste or content of phlegm is usually caused by an underlying medical condition. In some cases, a person may experience a salty taste only in their phlegm, while in others it may be accompanied by other symptoms. Conditions that can cause a salty taste in phlegm include sinus infections, allergies, and acid reflux.
Sinus Infections
A sinus infection, or sinusitis, is an infection or inflammation of the sinuses. It is usually caused by a virus, but can also be caused by bacteria, fungi, or allergies. Symptoms of a sinus infection can include a stuffy or runny nose, a headache, facial pain, a sore throat, and a salty taste in the phlegm.
When a person has a sinus infection, the mucous membranes in the sinuses become inflamed and irritated. This can cause a salty taste in the phlegm as the mucous membranes produce more mucus than normal. In addition, the mucous membranes may secrete a salty fluid, which can also cause a salty taste in the phlegm.
Allergies
Allergies are an overreaction of the body’s immune system to certain substances. Allergens can be anything from pollen and dust to pet dander and food. When a person is exposed to an allergen, their body produces a chemical called histamine, which can cause inflammation and irritation in the respiratory tract. This can lead to an increase in mucus production, which can cause a salty taste in the phlegm.
In addition, some people may be sensitive to certain foods or medications, which can also cause a salty taste in their phlegm. Common food allergens include dairy products, wheat, eggs, and peanuts. Common medications that can cause a salty taste in phlegm include antibiotics and non-steroidal anti-inflammatory drugs (NSAIDs).
Acid Reflux
Acid reflux is a condition in which stomach acid backs up into the esophagus. The acid can irritate the lining of the esophagus, leading to a burning sensation in the chest or throat. In some cases, the acid can travel far enough up the esophagus to reach the vocal cords and throat, which can cause a salty taste in the phlegm.
