Do you sometimes think that when you have a stomach ache or gastritis , it's normal? Many people do. But sometimes, tests done for these symptoms can reveal something we wouldn't even think of. That's what's called Intestinal Metaplasia, a condition that's not visible at first glance, but needs to be taken into account. Let's talk about this simply today, okay?
So, what is this (Intestinal Metaplasia)?
Simply put, Intestinal Metaplasia is a condition where the cells in your upper digestive tract , that is, your stomach or esophagus (the tube through which we swallow food), change. What happens is that the cells in those areas start to look like the cells in the intestines. That's why it gets the "intestinal" part, meaning "like the intestines." When doctors see this, it looks like the lining of your stomach or esophagus has been replaced with the lining of the intestines.
Imagine this: You have a certain type of tile on your kitchen wall. Over time, for some reason, those tiles start to be replaced by the same type of tiles you use in your bathroom. That's what happens here too.
When this condition occurs in the esophagus, it is also called Barrett's esophagus . When it occurs in the stomach, it is also called gastric intestinal metaplasia .
Who is most affected by this situation?
Scientists believe that this cell change (metaplasia) occurs when cells are exposed to long-term stress or irritation . This stress can come from a variety of environmental factors . For example:
- Smoking
- Alcohol use
The main cause of Intestinal Metaplasia or Barrett's esophagus is long-term irritation of the esophagus due to acid reflux . If you have had symptoms of GERD (Gastroesophageal Reflux Disease) for a long time, smoke, or drink alcohol, you are more likely to develop this condition.
On the other hand, the main factor that causes intestinal metaplasia is a bacterial infection called Helicobacter pylori . This bacteria damages the protective mucous lining of the stomach. Also, a condition called autoimmune metaplastic atrophic gastritis is a cause of intestinal metaplasia. In this, your body's own immune system attacks the cells in the stomach. This can also be hereditary.
Is Intestinal Metaplasia serious?
Yes, this condition is considered a risk factor for cancer . This is not cancer , remember. However, it can be a step on the path to cancer. Once cells change once, they are more likely to change again. If these cells undergo another change called dysplasia , they become precancerous cells. Only then does cancer develop.
Important: Intestinal Metaplasia is not cancer. However, it does increase the risk of developing cancer. Therefore, it is important not to panic and follow your doctor's advice.
What are the stages of Intestinal Metaplasia?
As the condition (Intestinal Metaplasia) becomes more severe, it progresses to a condition called (dysplasia). It also has two stages:
(Low-grade dysplasia)
In this, some cells show early changes in shape and structure. Although these are considered precancerous cells, they do not appear to be changing rapidly. Your doctor may recommend treatment for this condition (low-grade dysplasia) before it gets worse.
(High-grade dysplasia)
In this stage, more complex changes in the cells can be seen. But they do not yet appear to be spreading (invasive). This is one step closer to cancer. Your doctor will tell you to treat this condition (high-grade dysplasia) before it becomes cancer.
What are the causes of (Intestinal Metaplasia)?
Intestinal metaplasia appears to occur as a response to long-term stress in the tissues of the stomach or esophagus. Scientists don't fully understand why it develops in some people and not in others. However, it seems to be caused by a combination of factors:
- The number of different irritants that affect tissues.
- The severity of those distressing things.
- How long (duration) the tissue has been exposed to those stresses.
- Genetic predisposition – this means if someone in the family has the condition (IM), or stomach or esophageal cancer.
How is Intestinal Metaplasia treated?
Doctors treat this condition by trying to eliminate the irritants that cause it, in the hope that this will at least prevent the metaplasia from getting worse.
- Stop smoking and alcohol use .
- Treating acid reflux .
- Eradication of ( H. pylori ) infection.
Doing these things gives your tissues a chance to heal from the chronic inflammation that causes metaplasia. If the condition progresses to dysplasia, doctors may recommend removing the affected tissue to prevent it from turning into cancer.
Summary and things to remember
Okay, so intestinal metaplasia in the stomach or esophagus is a sign of some damage. It can be reversible or it can go away. Even if it doesn't cause symptoms, it means that significant damage has already been done. And, it's a warning that if this damage isn't stopped, more serious damage could occur.
Even though the risk of developing cancer is low, it is important to take this warning seriously and try to reduce or eliminate the things that can damage your stomach or esophagus. If given the chance, you may be able to partially or completely recover and avoid bad outcomes. So, the best thing to do is not to panic, take care of your body, and follow your doctor's advice carefully.
