Is mucus as bad as you think? Let's learn the AZ about it!

When you think of "mucus," you probably think of things like the stuffy nose and the thick mucus that gets stuck in your throat, right? You might think of mucus as just a nuisance, something that needs to be cleared out of your body as quickly as possible. But, did you know that this mucus is actually a very important, superhero-like part of our body's defenses? Let's talk about this mucus today, shall we?

What exactly is mucus?

Simply put, mucus is a thick, slightly slippery fluid that is found inside our bodies. It's like jelly. It covers our respiratory system (i.e. nose, throat, lungs), digestive system (i.e. intestines), urinary system, and reproductive system.

Think of it like a protective shield inside our body. This shield stops harmful germs (pathogens) from entering the body. It also helps our body absorb the good things we need, like oxygen and nutrients. Another thing is that mucus keeps the organs inside our body moist and slippery. This is very important.

You may have heard of phlegm as "phlegm/sputum." We often think of phlegm when we have a runny nose or a stuffy throat. But the truth is, phlegm is a very important part of our immune system . It constantly fights to protect us from illness.

What service does mucus provide to our body?

Now you probably understand that mucus is not just a thing. Look at how much mucus does to our bodies:

• Stops germs and harmful substances: Mucus prevents harmful substances like germs and dust from entering our body, just like a gatekeeper.
• A storehouse of antibodies: Mucus contains a special type of protein called ``Antibodies.'' These inactivate germs that enter the body and identify them to immune cells to destroy them.
• Captures and expels harmful substances: Imagine you are walking on a dusty road. Then the dust particles that enter your nose get stuck in this mucus, and then come out of your nose in a puff. In the same way, mucus helps us capture and expel harmful substances from our body.
• Moisturizes Mucosa: Mucus helps keep the delicate membranes ( mucosal) that open to the outside of our bodies (like the nose and mouth) moist.
• Makes mucous membranes slippery: This is very important. For example, the food we eat moves easily through the intestines because of the slippery nature of this mucus. Similarly, in the female reproductive system, cervical mucus helps prepare the way for sperm to reach an egg.

How is this mucus formed? Where does it come from?

Where do you think this mucus comes from? This mucus is made by a special type of cell in our mucous membrane `(Mucosa). They are called `(Goblet cells)`. These cells are called that because they are shaped like a small glass. These cells and some other cells come together to make `(Mucin)`, which is the main component of mucus.

This mucus is found in these places on our body:

• Sense organs: eyes, ears, mouth, nose.
• Respiratory system: lungs, trachea.
• Digestive system: stomach, intestines.
• Urinary system: bladder, urethra.
• Female reproductive system.
• Male reproductive system.

What does mucus actually contain?

The substances in mucus are what give it its thick, slippery texture, and help protect us from germs. Let's take a look at what's in mucus:

• Water: Mucus is mostly water.
• Electrolytes: Salts necessary for the body to function.
• Enzymes: Enzymes that help destroy germs.
• Antibodies (Immunoglobulins): Proteins that fight germs.
• White blood cells: These are the soldiers in our body. They fight germs.
• Mucin: This is a special type of protein. It is this mucin that gives mucus its jelly-like consistency.

What does mucus normally look like? Does it change color?

Normally, a healthy person's mucus is clear, slightly runny, and slippery. But when you have a cold or an infection like sinusitis, the mucus that comes out of your nose and throat can become thick, sticky, and a creamy white color.

There are many reasons why mucus can change color. Things like dead cells, germs, and cigarette smoke can change color when they accumulate in the mucus. Here's what these colors mean:

• White, cream, or light yellow: If your mucus is thick and this color, it means you're fighting a cold or other viral infection. This color and consistency come about when your immune cells are fighting germs.
• Bright yellow or green: This is also usually a sign of an infection. Depending on the other symptoms you have (e.g. headache, facial pain) and how long you've had this condition, it could be sinusitis or a bacterial infection.
• Red or pink: The mucus may appear pink or streaked with red if there is a little blood in it. This can happen if the skin inside the nose is dry and damaged. Small blood vessels inside the nose can also burst, causing blood to accumulate in the mucus.
• Brown: Air pollution and smoking can cause this type of brown mucus. However, sometimes it can also be a sign of an infection.
• Black: This could be due to something you've inhaled (e.g. coal fumes). However, sometimes it can also be a sign of a dangerous fungal infection.

The most important thing: You can't tell exactly what illness you have just by looking at the color of your mucus. If your mucus is dark (black, dark brown), or any other color that you suspect, especially if you have other symptoms like facial pain or headaches, you should definitely see a doctor.

So what color is healthy mucus?

If you don't have any illness, your mucus is usually clear. Thick, creamy, yellow, or green mucus can mean you have an infection. However, if you have an allergy, you may have very clear, runny mucus coming out of your nose.

What diseases affect the mucous membranes?

Anything that causes inflammation anywhere in our body or stimulates our immune system can cause changes in the amount, color, and thickness of mucus. Hormonal and genetic conditions can also affect this. Some conditions that can affect mucus include:

• Infections: Sinusitis or respiratory infections are the most common causes of excessive mucus production in the nose and throat.
• Allergies or irritants: When allergens or other irritants enter the respiratory system, more clear mucus can be produced.
• Lung diseases: Chronic lung diseases such as bronchiectasis and chronic obstructive pulmonary disease (COPD) can cause mucus to accumulate when the lungs and airways are damaged.
• Cystic fibrosis: This is a genetic disease that causes the pancreas and lungs to produce very thick, sticky mucus.
• Digestive system problems: Conditions like diverticulitis, inflammatory bowel disease (IBD), irritable bowel syndrome (IBS), and anything that stimulates the digestive system can cause mucus in the stool.
• Hormonal issues: Menopause and low estrogen levels can reduce the amount of mucus in the reproductive system. This can lead to decreased fertility and vaginal dryness.
• Cancer: Some types of cancer, such as mucinous carcinomas, can arise from mucin.

What can you do to get rid of excess sebum?

Most of the time, you have to deal with this excess mucus when you're sick. The body is trying to get rid of germs and dead immune cells. Here are some things that can help reduce this mucus:

• Expectorants: These help thin out thick mucus and remove it from the chest.
• Nasal rinses: These can help break up mucus in the nose and sinus cavities. However, you need to follow the instructions carefully to use them safely.
• Decongestants: These medications or sprays can temporarily reduce swelling and mucus in the nose and throat.
• Antihistamines: These help to stop the excessive production of mucus due to allergies or to control the condition.
• Mucolytics: These are used to treat chronic lung diseases such as cystic fibrosis.

What time do you need to see a doctor?

If your phlegm is an unusual color (like bright yellow or green), very thick, or seems to be bloody, you should definitely see a doctor. Your doctor can then check if you have an infection that needs treatment.

Are "Mucus" and "Phlegm" the same thing?

"Phlegm" is what we usually call "phlegm in the throat" or "phlegm in the chest." This is also a type of mucus. But it usually comes from the lower parts of our respiratory system (like the lungs). It is thicker than normal mucus because it is fighting an infection.

Is it better to swallow the mucus that comes from the throat or to spit it out?

When you have mucus in your throat, swallowing it won't hurt. But some people may cough or feel a lump in their throat when they swallow it. Or, some people may find it "unpleasant." So, there's nothing wrong with blowing your nose – but you should do it with consideration for others.

If possible, put the mucus on a tissue or napkin and throw it in the trash. Be sure to wash your hands thoroughly with soap and water afterward. If a tissue is not available, be a little distance away from other people and let the mucus out.

Finally, things to remember

Now you know that mucus is the unappreciated hero of our immune system. Although it may seem like a nuisance to us when we get sick, this mucus in our throat, all of it, is actually fighting for you. This mucus is constantly working to protect your body from germs and other things that can harm you.

If you notice changes in your mucus (color, amount, consistency), it can sometimes give you a clue that something is wrong with your body. Therefore, if you feel something strange or suspicious about your mucus, the best thing to do is to see a doctor and get advice. They can help you decide whether it's normal or something to be concerned about.
