Why does my body produce so much mucus?

Excess mucus has many potential causes. They can be long- or short-term. Conditions that can contribute to excess mucus include allergies, asthma, and bronchitis. Smoking and conditions like COPD and cystic fibrosis can also cause this symptom.

Where does all the mucus come from when you have a cold?

When you have a cold, your nose and sinuses are more vulnerable to a bacterial infection. A cold virus can trigger the body to release histamine, a chemical that inflames your nasal membranes and causes them to produce a lot of mucus.

Is mucus coming out good?

It protects the tissue that lines your lungs, throat, and nasal and sinus passages and keeps them from drying out. Mucus contains antibodies and enzymes, designed to kill or neutralize harmful bacteria in the air. Think of it as a line of defense that can prevent you from getting sick.

Where does mucus build up come from?

Respiratory infections like colds, the flu, and sinusitis are common causes of increased mucus production and coughing up mucus. Allergic reactions are another reason that mucus production can increase. Even consumption of spicy foods can spark excess mucus production in the nasal passages.

Is it good to spit out mucus when sick?

Coughing and blowing your nose are the best ways to help mucus fight the good fight. “Coughing is good,” Dr. Boucher says. “When you cough up mucus when you are sick, you are essentially clearing the bad guys—viruses or bacteria—from your body.”

Should you swallow mucus?

So here’s the big question: Do you spit or swallow your phlegm? Even though it might taste nasty, “there’s nothing wrong with swallowing it,” Dr. Comer says. In fact, that’s probably what your body expects you to do, which is why phlegm naturally drains down into the back of your throat.

Is it OK to swallow phlegm?

So, to answer your questions: The phlegm itself isn’t toxic or harmful to swallow. Once swallowed, it’s digested and absorbed. It isn’t recycled intact; your body makes more in the lungs, nose and sinuses. It doesn’t prolong your illness or lead to infection or complications in other parts of your body.
