When you swallow a meal, have you ever wondered how exactly it goes to your stomach? Or do you sometimes feel a burning sensation in your chest after eating a spicy meal, and you think, "Oh my, what is this?"? We've all had these experiences. Today we're going to talk about a very important part of our body that's involved in all of this. That's the esophagus, or as it's called in English, `(Esophagus)`.
Simply put, what is the esophagus?
The esophagus is, to be precise, our food pipe. That is, it is a muscular tube that carries food and liquids from your throat to your stomach. It is a very important part of our digestive system. When we swallow food, it does not go straight into the stomach. The esophagus is the bridge that carries it to the stomach in an orderly, safe manner.
Imagine you swallow a mouthful of rice. First, it goes from your mouth to your throat. There, a little flap of muscle, called the epiglottis, closes. Do you know why? It's to keep your food from going the wrong way, into your windpipe (trachea). There's also a little part of your throat called the uvula that keeps what you drink from going into your nose. All of this happens without you even realizing it. Isn't it amazing?
How does the esophagus work? It's a very amazing mechanism!
This is a very strange process. At the top and bottom of the esophagus, there are two rings of muscle that act like two doors. We call these ``sphincters``.
1. Upper Esophageal Sphincter: This is where the esophagus begins. When you swallow food, this valve gets a signal saying, "Here comes the food." At that time, it opens. After the food goes in, it closes again. At other times, it is tightly closed.
2. Peristalsis: Once food enters the esophagus, it doesn't just fall down. The muscles in the walls of the esophagus contract (contract) like a wave, pushing the food down. This is what we call ``peristalsis.'' This process moves food into the stomach whether you are standing or lying down.
3. Lower Esophageal Sphincter (LES): After the food has gone all the way down, there is another opening before it enters the stomach. That is the lower sphincter. Like the upper one, this one also opens when food comes in and lets the food pass into the stomach. Then it closes tightly again.
It is very important that this lower gate closes properly. Because, this gate prevents the stomach acid and digestive juices from coming back up, that is, into the esophagus. The main reason for the problem of "gastritis" or "heartburn" that many people have is that this lower gate does not work properly.
Esophagus and trachea - let's know the exact difference between the two
Many people confuse the two. The esophagus and the trachea are two tubes located near each other in the neck, but they have completely different functions.
| Characteristic | Esophagus | Trachea |
|---|---|---|
| System | Part of the digestive system | Part of the respiratory system |
| Main function | Transporting food and drink from the throat to the stomach | Taking air (breathing) into and out of the lungs |
| Location | Located behind the trachea and in front of the spine | Located in front of the esophagus |
What are the common diseases and conditions that affect the esophagus?
Our food can also cause various diseases. You may have heard of some of these.
Chest inflammation and GERD condition
This is the most common problem. The lower esophageal sphincter (LES) that I mentioned earlier does not close properly, allowing stomach acid to flow back up into the esophagus, which is what we call ``Acid Reflux''. This is what causes heartburn.
If this `Acid Reflux` continues and happens frequently, we call it Gastroesophageal Reflux Disease (GERD) . This is a serious condition. In addition to heartburn, symptoms such as a sour taste in the mouth, coughing, chest pain, hoarseness, and difficulty swallowing may also occur. If GERD is not treated properly, it can cause serious damage to the esophagus over time.
Other medical conditions
In addition to GERD, a number of other problems can occur.
| Medical condition | Simply put... |
|---|---|
| Achalasia | This is a rare disease. What happens here is that the lower esophageal sphincter (LES) doesn't open when it should. So food can't pass into the stomach. |
| Esophageal Diverticulum | A small pouch that protrudes from a weak spot in the wall of the esophagus. If this pouch becomes large, food may become stuck and make it impossible to swallow. |
| Esophageal Varices | Swelling of blood vessels in the esophagus. If these burst and bleed, they can be life-threatening. |
| Esophagitis | Inflammation of the lining of the esophagus. This can be caused by acid reflux, infections, or certain medications. |
| Barrett's Esophagus | Long-term GERD causes changes in the cells of the lower esophagus, which increases the risk of esophageal cancer. |
Very rarely, esophageal cancer can occur. There are two main types: adenocarcinoma and squamous cell carcinoma.
How do you know if you have these problems? What are the symptoms?
If you have a problem with your esophagus, you may experience a variety of symptoms. If you have one or more of these, it's important to pay attention.
- Heartburn: A burning sensation in the middle of the chest, behind the ribs.
- Difficulty swallowing (Dysphagia): A feeling of choking or pain when swallowing food.
- Regurgitation: The return of undigested food into the mouth.
- Chest pain: A feeling of tightness or pain in the chest, even if it doesn't feel like a heart attack.
- Persistent cough: A cough that gets worse, especially at night.
- Hoarseness or sore throat.
- Bad breath (Halitosis).
- Being thin for no reason.
- Vomiting or vomiting blood.
If you have any of these symptoms, especially difficulty swallowing, food getting stuck, vomiting blood, or significant weight loss, see your doctor right away . These could be signs of something more serious than simple gastritis.
How does a doctor diagnose these conditions?
When you go to see a doctor, he will ask about your symptoms and, if necessary, recommend some tests. Don't worry, these are the ones that will help you find out exactly what's wrong.
- Upper Endoscopy: This involves inserting a thin, flexible tube with a camera through the mouth to examine the esophagus, stomach, and first part of the small intestine. This allows for a clear look at the inside for any injuries, inflammation, or changes.
- Biopsy: During the endoscopy, a small piece of tissue is taken from the suspicious area and sent to the laboratory to be tested. This can help determine if there are any cancer cells present.
- Barium Swallow: In this test , you are given a chalky liquid to drink. Then, several X-ray pictures are taken. The barium liquid allows the X-ray to clearly show the shape of the esophagus and how food moves through it.
- Esophageal pH test: A very thin tube is inserted through the nose into the esophagus and left in place for about 24 hours to measure how often and for how long stomach acid comes up. This helps to accurately determine the severity of GERD.
How is it treated?
Treatment options depend on the condition you have. Sometimes, diet and lifestyle changes can make a big difference. Some people need medication, while others may even need surgery.
Types of drugs
- Antacids: These temporarily neutralize the acid in the stomach. They are used to provide quick relief from heartburn.
- H-2 Receptor Blockers: These reduce the production of acid in the stomach.
- Proton Pump Inhibitors (PPIs): These are more effective at blocking acid production than H-2 blockers, and they also help heal damage to the esophagus caused by acid.
- Other medications: Medications like Baclofen reduce the involuntary opening of the lower esophageal sphincter (LES).
Special procedures and surgeries
- Esophageal Dilation: If the esophagus is narrowed (stricture) due to long-term inflammation, a device such as a balloon is used to widen the narrowed area.
- Laparoscopic Antireflux Surgery: This involves taking the upper part of the stomach and wrapping it around the lower part of the esophagus, creating a new valve. This strengthens the lower esophageal sphincter (LES) and stops acid from coming up.
- LINX device implantation: A magnetic ring-like device is implanted around the lower esophagus. This prevents acid from coming up, but allows food to pass down more easily.
- Esophagectomy: In very severe cases, such as cancer, the esophagus may need to be surgically removed.
Take-Home Message
- The esophagus is a very important part of our digestive system. Its proper functioning is essential for a healthy life.
- Don't ignore symptoms like frequent heartburn, a sour taste in the mouth, or difficulty swallowing as normal. They could be early signs of a medical condition.
- Even simple things like limiting spicy, oily foods, coffee, and chocolate, and not lying down for 2-3 hours after eating at night can provide you with great relief.
- If you have any concerns about your symptoms, don't be afraid to talk to your doctor . It's more important to get a proper diagnosis and treatment than to self-medicate.
