About the Symptoms, Causes, Treatment, and Prevention of Intestinal Metaplasia

Symptoms of intestinal metaplasia,

causes, treatment, and prevention

Every year, when the time for health checkups comes around, many people worry about undergoing stomach and colon

endoscopy because of the complicated preparation process and the pain that may accompany it.

These examination methods do more than simply identify symptoms;

they help detect lesions early that can lead to cancer, such as intestinal metaplasia and adenomatous polyps.

Today, we will take a detailed look at the causes and symptoms of intestinal metaplasia, as well as its diagnosis,

treatment, and prevention methods.

Intestinal metaplasia is a condition in which the cells of the stomach lining

change to resemble intestinal cells, meaning the normal gastric mucosa is replaced by tissue-like changes similar to intestinal tissue.

Because this disease is a precancerous lesion that increases the likelihood of stomach cancer, the stomach becomes more vulnerable to gastric acid and its protective function is weakened, so prompt treatment is needed.

It is usually diagnosed through a biopsy during gastroscopy, and because the symptoms are not clear, many people live without realizing they have it.

The main cause is infection with Helicobacter pylori,

which triggers chronic inflammation in the stomach lining and induces changes in mucosal cells.

In addition, salty or burnt foods, smoking, excessive drinking, and irregular eating habits are also factors that increase the likelihood of occurrence, and if there is a family history of stomach cancer, the risk is higher.

Moreover, the prevalence increases with age,

and it occurs frequently, especially in middle-aged and older adults in their 50s and above, so early diagnosis through testing is necessary.

If the gastric mucosa continues to be damaged, intestinal metaplasia may progress extensively and the risk of progression to stomach cancer may increase, so caution is needed.

The disease itself often does not involve pain or discomfort, but in some cases people may complain of chronic indigestion, heartburn, or abdominal bloating.

Therefore, if it is left untreated without regular checkups, it can lead to progressive lesions or gastric adenocarcinoma, so early detection and proper management are necessary.

If you are diagnosed with the disease, the first priorities are thorough improvements in lifestyle habits and the rapid elimination of risk factors.

If Helicobacter pylori is found, eradication treatment is performed, and even after the procedure, regular gastroscopy is needed to follow up on the condition of the gastric mucosa.

In terms of diet, you should reduce your intake of salty or burnt foods, instant foods, and processed meats, and it is better to build a diet centered on fresh vegetables and fruits.

The interval for regular endoscopic examinations varies depending on the extent and severity of the disease, but generally follow-up observation is recommended at intervals of 6 months to 1 year.

If high-risk lesions are present in the biopsy results, or if there is a family history, undergoing more detailed examinations at shorter intervals can help prevent stomach cancer.

Even if the cause is removed and management is successful through treatment, once the gastric mucosa has changed, it is difficult to return completely to normal, so please continue to manage it consistently.
