Let's get to know your "stomach" exactly. (Stomach) This is like a little factory!

We all know the word "stomach". We feel it when we are hungry and when we are full. But what exactly is this "stomach"? In medical terms, we call it the "stomach". This is an amazing organ inside our body. It works like a little factory that digests food. So, today we will learn about this stomach, what happens in it, and how to take good care of it simply, as if we were talking to a friend.

What is the stomach? The shape of the letter J!

Simply put, the stomach is a J-shaped organ that plays a major role in digesting the food we eat. Inside the stomach, food is broken down, ground, and liquefied. It uses two special substances to do this.

1. Enzymes: These are proteins that help break down chemicals in food. Think of them as scissors cutting up food.

2. Digestive juices / Acids: These are what further break down food and destroy any germs that may be present in it.

This mixture of enzymes and acidic substances is what digests food thoroughly and makes it ready for passage into the small intestine .

Did you know that the stomach is a very important part of our gastrointestinal tract (GI tract) . This GI tract starts from our mouth and ends at the anus, where feces are expelled. This entire system is called the digestive system .

What are the main functions of the stomach? Here's what it does!

The stomach has three main functions to help with the digestive process:

1. Storing food for a while: When we eat, we don't send it all at once. The stomach holds it for a while, digests it, and then sends it forward little by little. Think of it like a small warehouse.

2. Contraction and expansion to mix and break up food: The walls of the stomach are made up of muscles. These muscles contract and expand. Like a blender, they mix the food well and break it into small pieces.

3. Producing enzymes and special cells needed to digest food: As mentioned earlier, chemicals that help digest food are produced inside the stomach.

How does the stomach work together with the rest of the digestive system?

Our digestive system is like a team. Every part does its job properly. Here's what happens from the moment we take food into our mouths:

  • Mouth: When you chew and swallow food, the tongue pushes the food down into the throat. Then there is a small piece of tissue called the epiglottis , which closes off our windpipe. That's why food goes straight to the stomach instead of going into the airway. Otherwise, it gets stuck.
  • Esophagus: This is just a tube. Food travels down this tube. At the bottom of the esophagus is a ring-shaped muscle called the esophageal sphincter . This opens to allow food to enter the stomach. This sphincter is a ring-shaped muscle that can tighten or relax at will.
  • Stomach: This is where digestive juices are produced and food is broken down and ground. Food is held here for a while until it is ready to be sent to the small intestine.
  • Small intestine: This is where food is thoroughly mixed with digestive juices from the intestines, liver, and pancreas. The walls of the small intestine absorb nutrients and water from the food. The remaining waste products are sent to the large intestine.
  • Large intestine: This is where waste is converted into stool, which is then pushed to the last part of the anus.
  • Rectum: This is the lowest part of the large intestine. Stool is stored here for a while and is only released when we need to have a bowel movement.

See, this is like a factory routine, right?

Where exactly is the stomach located in our body?

Your stomach is located in the upper part of your abdomen, on the left side . The upper part of the stomach is connected to the esophageal sphincter , which is the muscle that closes the esophagus. The lower part of the stomach is connected to the small intestine.

How big is our stomach?

The size of the stomach can vary from person to person . Also, the stomach gets bigger when you eat and is full, and gets smaller again when you are empty. Just like a balloon. So, the size of the stomach can change depending on how much you eat and how long it has been since you ate.

What are the main parts of the stomach? Let's get to know them too!

The stomach can be divided into five main sections, much like the rooms in a house:

1. Cardia: This is the uppermost part of the stomach. The cardiac sphincter is located here. This is what prevents food from coming back up the esophagus.

2. Fundus: This is the slightly rounded part of the heart, near the cardia. It is located under your diaphragm (the transverse muscle that helps you breathe).

3. Corpus: This is the largest part of the stomach. This is where the stomach contracts and begins to mix food.

4. Antrum: This is located below the stomach. Food is stored in this part until it is ready to be sent to the small intestine.

5. Pylorus: This is the lowest part of the stomach. The pyloric sphincter is located here. This ring-shaped tissue controls when and how the contents of the stomach are passed into the small intestine.

Imagine all these parts working together, like an organized team. When one part is finished, it is handed over to the next part.

How is the stomach wall formed? Does it have layers?

Yes, the stomach wall is made up of several layers of muscle and other tissue. It's like an onion with layers:

  • Mucosa: This is the inner lining of the stomach. When your stomach is empty, this mucosa has small folds (also called rugae ). When your stomach is full, this mucosa stretches out and those folds flatten.
  • Submucosa: This contains connective tissue, blood vessels, lymph vessels (part of the lymphatic system ), and nerve cells. This is what covers and protects the mucous membrane.
  • The outer muscular layer (Muscularis externa): This is the main muscular layer of the stomach. It has three layers. These contract and expand to break up the food.
  • Serosa: This is the membrane that covers the outside of the stomach.

The stomach is able to do its job properly because each of these layers performs its specific function.

What diseases can affect the stomach?

Unfortunately, this important organ of ours can also develop various diseases. We call these gastrointestinal diseases . Sometimes, symptoms may only occur at specific times, such as during pregnancy, such as heartburn. Or, they may be long-term (chronic) conditions.

Here are some of the most common conditions that affect the stomach:

  • Gastric ulcers: These are sores that form when the lining of the stomach is eroded. This can cause stomach pain and bleeding.
  • Gastritis: Inflammation or swelling of the lining of the stomach.
  • Gastroesophageal reflux disease (GERD): This is when stomach contents (especially acid) flow back up into the esophagus. This can cause heartburn, coughing, and other symptoms. This is commonly known as "gas."
  • Gastroparesis: Nerve damage causes the muscles in the stomach to weaken, causing food to not move through the stomach properly.
  • Indigestion / Dyspepsia: A feeling of discomfort, pain, or burning in the upper stomach.
  • Peptic ulcer disease: The formation of sores in the stomach or the first part of the small intestine (duodenum).
  • Stomach cancer: Cancerous growth of cells in the stomach that grows out of control.

If you have symptoms like these, it is very important to seek medical advice .

What should we do to maintain a healthy stomach?

Good gut health is essential for a healthy life. We can keep our gut and entire digestive system healthy by making a few simple lifestyle changes.

  • If you use alcohol, limit it. It's best to drink as little as possible, or stop altogether.
  • Depending on your activity level and body size, drink at least 50 ounces of water per day (about 1.5 liters).
  • Depending on your age and gender, aim to eat at least 25-35 grams of fiber per day. Fiber is abundant in leafy greens, vegetables, fruits, and whole grains.
  • Exercise regularly.
  • Limit processed foods as much as possible.
  • Use healthy methods like meditation to manage stress .
  • If you smoke or use tobacco products, stop.

Following these things will provide great relief to your stomach.

What should I ask the doctor about my stomach?

If you have persistent stomach symptoms, you may want to see a gastroenterologist . You can ask him/her questions like:

  • What is the most likely cause of my symptoms?
  • What tests are done to diagnose a stomach condition?
  • Are there any medications that can be purchased at the pharmacy to reduce these symptoms?
  • Do I need to change my diet?

Don't be afraid to ask the doctor any questions you have.

When should you see a doctor?

There are some symptoms that you should see a doctor immediately if you notice them. They are:

  • Chest pain.
  • Fever.
  • Nausea and vomiting.
  • Pus or blood in the stool.
  • Severe dehydration or diarrhea.
  • Sudden severe stomach pain.

If something like this happens, don't stay home and see a doctor immediately.

Take-Home Message

So, we've talked a lot about the stomach today, haven't we? Remember, the stomach is an important muscular organ located in the upper abdomen. It's part of our digestive tract (GI tract). During digestion, the stomach contracts, expands, and produces acids that help digest food. The size of the stomach can change depending on what you eat and drink, and how long it's been since you've eaten. By eating a healthy diet, exercising regularly, and managing stress, you can keep your stomach and your entire digestive system healthy. So, don't forget to take care of your "stomach"!
