Most of us have had some stomach discomfort at some point in our lives, right? Sometimes it's bloating, stomach pain, or just not being able to go to the bathroom. Some of these things get better in a day or two. However, sometimes these discomforts can be a sign of a bigger problem that lasts a little longer or occurs more frequently. That's when we need to think about gastrointestinal diseases . So, today we'll talk about this in a simple way that you can understand.
What are Gastrointestinal Diseases?
Simply put, this refers to the various diseases and conditions that affect your digestive system (Gastrointestinal (GI) tract) . Now you may be wondering what the digestive system is. It is the entire path that the food you eat travels from your mouth to your stomach, where it is digested, absorbed, and eliminated as waste. This includes your mouth, throat, esophagus, stomach, small intestine, large intestine, rectum , as well as the organs that help you digest food, such as the liver, pancreas, and gallbladder . So if there is a problem anywhere in this system, that is what we call a GI disease.
There are two main types of GI diseases:
These diseases can be mainly divided into two parts.
1. Diseases that develop quickly and get better in a short time (Acute GI Diseases)
These are illnesses that start suddenly and last for a short period of time, like a few days or a few weeks. For example, sometimes we get diarrhea after eating something that doesn't suit us, and that's what happens. These usually get better quickly if treated properly.
2. Chronic GI Diseases
These types of illnesses can last for months, even years. They may require long-term treatment and lifestyle changes.
Additionally, these GI diseases are also classified in another way:
Functional GI Diseases
This is a little special. What happens here is that when your doctor examines you, or even does an endoscopy, he can't find any visible structural defects, lesions, or nodules in your digestive system. But, you have symptoms. It's like there's nothing wrong with the machine, but it's not working. Things like bowel dysfunction and increased sensitivity are what happen here.
Structural GI Diseases
Here, when the doctor examines your digestive system , he or she can clearly see something wrong, such as inflammation (swelling), blockage, injury, or abnormal growth . These are usually a little more complex than ``functional`` diseases.
A little more about Functional GI Diseases
In fact, almost all of us have experienced a ``functional`` GI problem at some point in our lives. Examples include constipation (inability to pass stool properly), bloating, and diarrhea . These can cause some discomfort in the digestive system, and you may experience a variety of symptoms.
Let's see what are the main reasons for this?
- Diet: Low-fiber diet, high intake of processed foods.
- Lack of exercise: Lack of exercise for the body.
- Lifestyle changes: When traveling, or when your daily habits change.
- Stress and anxiety: This is the cause of many illnesses.
- Controlling your urge to go to the bathroom: Isn't that a good thing to do?
- Certain medications: It could also be caused by some medications you are taking.
- Hormonal changes: such as during pregnancy and menstruation.
- Sensitivity to certain foods: Some foods may be intolerant to you.
Most of the time, doctors recommend lifestyle changes as a treatment for these ``functional`` GI diseases. This means eating more fiber-rich foods (fruits, vegetables, and greens), drinking plenty of water, getting some exercise every day, and identifying and avoiding foods that irritate you. Sometimes these problems can get better on their own in a few days.
Structural GI Diseases
These are a little more complicated than the previously mentioned ``Functional`` diseases, and they can sometimes be serious . In these diseases, a doctor can clearly see something like inflammation, blockage, or injury when examining your digestive system. These are difficult to improve with lifestyle changes alone, and may often require medication or even surgery . Hemorrhoids, colon polyps, and inflammatory bowel disease (IBD) are some examples of these.
What are the most common GI diseases?
Doctors who specialize in diseases of the digestive system are called ``Gastroenterologists.'' Let's take a look at some of the common GI diseases they treat.
1. Constipation
This can cause difficulty passing stools, or it can take days to go to the bathroom. There may be a strong pressure when you have a bowel movement. This can often be controlled by drinking more water and eating foods high in fiber . Over-the-counter laxatives can also help. However, if this problem persists, it is best to see a doctor.
2. Irritable Bowel Syndrome (IBS)
This is a common problem among many people. What happens here is that the muscles in your intestines contract more or less than normal . This can cause symptoms like stomach pain, bloating, and gas. This can be controlled with dietary changes and medications prescribed by your doctor.
3. Hemorrhoids
This is when the blood vessels in or around your rectum become swollen . Straining during bowel movements is the main cause. Hemorrhoids can be managed by relieving constipation and taking steps to reduce straining. Sometimes, large, painful hemorrhoids may need to be removed by a doctor.
4. Diverticular disease
This is when small pouches called ``Diverticula`` develop in the wall of your large intestine . These are also called ``Diverticulosis``. When these pouches become infected, it is called ``Diverticulitis`` . This can cause bleeding and blockages in the intestines. Eating a high-fiber diet, ``Antibiotics``, and sometimes even surgery may be necessary.
5. Colon polyps and colon cancer
Colorectal cancer is one of the most common types of cancer today. Most of these cancers start as small growths (colon polyps) that form in the lining of the large intestine . These polyps are not cancerous (benign) at first. However, they can turn into cancer over time. That is why it is important to detect and remove them early through tests such as colonoscopy . If detected early, the cancer is more likely to be cured completely.
Remember, it is very important to get screened for colon cancer periodically, starting after the age of 45.
6. Colitis – Inflammation of the colon
This is not a single disease, but a general name for a group of diseases that cause inflammation of the intestines . Symptoms can include diarrhea, blood in the stool, stomach pain, and frequent bowel movements. Ulcerative colitis and Crohn's disease are two of the main diseases in this group.
7. Celiac disease
This is when you eat foods that contain gluten (a protein found in grains like wheat and barley), and your digestive system starts to have problems. Symptoms can include stomach pain, bloating, and gas. This is also considered an autoimmune condition . This is because your own immune system attacks the gluten. This attack can damage your small intestine and cause it to stop working properly.
8. Gastritis – Inflammation of the stomach
This is inflammation of the lining of your stomach . Symptoms can include loss of appetite, stomach pain, and nausea. It can be caused by infections, certain chemicals, and autoimmune diseases. It can often be treated with over-the-counter medications within a few days.
9. Gastroenteritis – Inflammation of the stomach and intestines
This is when inflammation spreads from the stomach to the intestines . The main symptoms are stomach pain, vomiting, and diarrhea. This is usually caused by a bacterial infection from spoiled food (food poisoning) or something like a stomach virus (stomach flu) . We've all had this happen to us at least once in our lives.
10. Acid reflux/Gastroesophageal reflux disease (Acid reflux/GERD)
This is when stomach acid comes back up into the esophagus (food pipe) and throat . This can cause a burning sensation in the chest and throat. It is treated with medications, dietary changes, and sometimes surgery.
11. Lactose intolerance
This happens when your small intestine can't properly digest lactose, a sugar found in milk and dairy products . Symptoms can include diarrhea, bloating, and gas. The main treatment is to avoid foods and drinks that contain lactose.
12. Indigestion/Dyspepsia
This refers to pain or discomfort in the stomach after eating . This is very common. It usually occurs within a few minutes to a few hours after eating. Taking an antacid can provide relief.
13. Barrett's esophagus
This changes the appearance of the lining of your esophagus (food pipe) . Sometimes, symptoms may go away completely. But it is often caused by ongoing acid reflux (Chronic acid reflux/GERD). People with this condition have a slightly increased risk of developing esophageal cancer .
What can we do to prevent GI diseases?
There are things we can do to reduce the risk of developing many GI diseases.
- Eat a nutritious diet: Include fiber-rich, fresh vegetables, fruits, and greens in your diet. Reduce fast food and oily foods.
- Exercise at least a few days a week: It is very important to keep your body active.
- Go to the bathroom as soon as you need to: don't hold it in.
- Get screened for colon cancer regularly: especially after the age of 45.
- See a doctor annually for a health checkup.
Living with a digestive disorder can be challenging at times. It can be difficult to manage symptoms and find relief. But remember that you are not alone. Millions of people around the world suffer from these problems. Your doctor and healthcare team are here to help you. Talk to them about your problems and how they are affecting your life. They will listen to you and recommend the best treatment options for your situation.
The most important things to remember
Digestive system diseases are a diverse group of diseases. Some are simple and get better quickly. Some require long-term treatment.
The most important thing is, if you have persistent stomach pain or discomfort, or if it occurs frequently, don't ignore it. Definitely see a doctor for advice.
If you do that, you can identify exactly what your problem is and start appropriate treatment quickly. Then you can recover quickly and go about your daily activities happily.
