Why do more than half of China people have chronic gastritis?

Nowadays, the taste of the year is getting weaker and weaker. The biggest expectation for migrant workers to go home during the Spring Festival, besides reuniting with their families, may be that they have a good table at home.

After staying at home for a few days in the New Year, I can finally get rid of takeout and canteen and eat something good at home. Even luxury items, such as lobster, king crab, and beef, which are usually reluctant to eat, are justified at the dinner table of the New Year's Eve.

But your stomach may not be as happy as you, and you have been eating for a few days. Before dinner time, my stomach swelled up first. Soon after eating, my stomach may hurt inexplicably again. I feel acid reflux and nausea in the middle of the night.

Although I still have a heart to eat food as in the past, your stomach tells you that it is no longer a stomach to eat food.

Without the opportunity to concentrate on eating and drinking during the Spring Festival, many people still don't know how fragile their stomachs are.

Every year after the Spring Festival, hospitals all over the country will usher in a wave of small peaks in the number of patients. Gastroenterology clinics are often full, and many patients are waiting in the waiting area with their stomachs covered.

Although this is a holiday disease caused by overeating, it is also a reminder. Because in China, there are quite a few people with stomach trouble, but few people are aware of their stomach trouble. More than half of China people may suffer from chronic gastritis.

Patients with chronic gastritis usually have no particularly consistent symptoms, and even some patients have no symptoms at all, so there has been no particularly accurate incidence statistics. However, the proportion of chronic gastritis patients in China can also be estimated by indirect methods.

The chief culprit of chronic gastritis is Helicobacter pylori, which is a bacterium with very high infection rate and is classified as a 1 carcinogen by the World Health Organization. It can survive in gastric acid environment, slowly eroding gastric mucosa and slowly destroying your stomach.

20 17 China chronic gastritis opinion points out that the main cause of chronic gastritis is helicobacter pylori infection. 70% to 90% patients with chronic gastritis are infected with Helicobacter pylori. On the contrary, almost all infected people have chronic gastritis. Therefore, through the proportion of Helicobacter pylori infection, we can probably infer how many people have hidden dangers of chronic gastritis.

The infection rate of Helicobacter pylori in China is quite high. A study by the Chinese University of Hong Kong collected 263 reports of Helicobacter pylori infection worldwide, and estimated that the infection rate of Helicobacter pylori in China was around 55.8%.

Generally speaking, the prevalence of chronic gastritis is slightly higher than that of Helicobacter pylori infection. There is even a relatively high estimate that the prevalence rate of chronic stomach diseases in China is as high as 90%. Even with a relatively low estimate, at least half of the people in China can't get rid of the shadow of chronic gastritis.

Maybe you haven't had any symptoms yet. At most, it is a little stomachache, bloating, acid regurgitation, and the most serious thing is vomiting. It will be fine in less than a day, but this is no reason to take it lightly.

Chronic gastritis is the killer of patients, and it takes time to attack and slowly damage people's gastric mucosa. The older you get, the more likely you are to suffer from chronic gastritis. When your parents are old, you may complain about the old stomach trouble.

In addition, even young people suffer from chronic gastritis. East China Normal University once conducted a small-scale survey, and more than 900 students with nausea, vomiting and abdominal pain were examined. The results show that nearly 65,438+00% students suffer from chronic gastritis.

Chronic gastritis is only the first step towards gastric collapse. About half of the patients with chronic gastritis will suffer from atrophic gastritis in different degrees, and about 5% of them will develop into advanced stage.

This is not the worst case. A small number of patients with chronic gastritis will follow the path of chronic gastritis-gastric mucosal atrophy-intestinal metaplasia-atypical hyperplasia: gastric cancer.

East Asia, especially China, Japan and South Korea, has been the hardest hit area of gastric cancer. Every year, 60% of the new cases of gastric cancer in the world come from East Asia.

In China, gastric cancer has long been the second largest cancer in China. According to the data of the World Health Organization Global Cancer Observatory, there will be about 478,000 new cases of gastric cancer in China in 2020, accounting for about 45% of the new cases in the world.

Gastric cancer is also a disease that is easier to get as you get older. With the increase of life expectancy, the median age of gastric cancer is close to 70 years old, which seems too far away for young people.

In the "Expert Opinions on Early Gastric Cancer Screening Process in China (Draft)" released on 20 17, it is also considered that the target population of gastric cancer screening is over 40 years old, and the target population in Japan and South Korea is even larger.

But this does not mean that gastric cancer has nothing to do with young people.

A study in the First Affiliated Hospital of Soochow University investigated the changes of gastric cancer data in China in 1990-20 19. They found that the incidence and mortality of gastric cancer in China are declining. Unfortunately, although the incidence of gastric cancer in all other age groups has decreased, the incidence of gastric cancer in the age group of 15 to 49 has been on the rise.

And like chronic gastritis, gastric cancer is also a very hidden killer. Nearly half of patients with gastric cancer have no early warning symptoms at all. In China, 90% of patients with gastric cancer have missed the early stage of gastric cancer which is convenient for treatment and come to the development stage.

More seriously, young people get stomach cancer, and the result may be more terrible than that of the elderly.

A study by the Mayo Institute in the United States found that early-onset gastric cancer and gastric cancer that is more likely to occur in the elderly have different genomic subtypes. It usually grows and spreads faster, has a worse prognosis and is more resistant to traditional chemotherapy.

A small-scale study by the Japan Cancer Research Foundation also confirmed that patients with gastric cancer under the age of 40 are more likely to have lymph node metastasis, and the survival rate of patients aged 60 to 69 is not good. In addition, it may be that young people don't care much about their physical condition and don't go to the hospital for examination as soon as possible. The proportion of advanced gastric cancer in young patients with stage ⅲ and ⅳ is also higher than that in other age groups.

Cancer is not a patent for the elderly. It's time to watch your stomach.

These hometown specialties should be eaten less.

If you want to pay attention to the health of the stomach, of course, you should start with diet. When I go home for the New Year, I will inevitably bring back some special products. When I came back, a suitcase smelled of my hometown. But these specialties should be eaten less no matter how delicious they are.

If you live in the northeast, you'd better eat less barbecue sauerkraut. If you go to the south for the New Year, you should eat less sausages and salted fish. If you live in the southeast, you should use less fish sauce and shrimp sauce. If you live in the southwest, you should not eat more ham. Because these diets have a common feature, high salt.

From a global perspective, Asia is the hardest hit area of high-salt diet. There are Lamian Noodles in Japan, kimchi in Korea, and several traditional foods with salt content in China.

These delicious foods may make you want to stop, but too much salt will directly damage the gastric mucosa and accelerate the progress of stomach diseases. Even salt will "cooperate" with Helicobacter pylori, promote the infection of Helicobacter pylori and cross-destroy your stomach. According to the research data of the World Cancer Research Foundation, people with high salt intake have a higher relative risk of gastric cancer 1.7 times than those with low salt intake.

Eat less pickled and smoked food. These foods are not only high in salt, but also high in carcinogen nitrite.

Smoked and roasted processed meat products, and carcinogenic substances such as polycyclic aromatic hydroxyl groups. High salt, nitrite and polycyclic aromatic hydroxyl intersect, and eating it is the next carcinogenic package. A transnational study found that eating 50 grams of processed meat every day would increase the incidence of non-cardiac gastric cancer 18%.

In fact, whether it is curing or smoking, it was originally used as an antiseptic measure under the condition of insufficient food preservation. Although food has survived, it has destroyed health. If there are other options, it is better to eat as little as possible.

A study by the German Cancer Research Center in the early 1990s found that buying a refrigerator as early as possible can actually prevent stomach cancer. Maybe refrigerators were not popular then. With a refrigerator at home, you can eat less pickled food and stale meals, which reduces the risk of stomach cancer. Now that almost every household has a refrigerator, the old habit of eating pickles and bacon should be changed.

The effect of changing eating habits can be seen from the changes before and after Asian immigrants go abroad.

According to the research of Korea National Cancer Center, the changes of incidence of gastric cancer after Asian immigrants went to California from 1988 to 2007 were counted in detail. The study found that the incidence of gastric cancer in the first generation of Asian immigrants continued to decrease, and in their next generation, the incidence of gastric cancer was almost close to that of native Americans. Among them, the change of immigrants in China is the most obvious, and their incidence of gastric cancer is about three quarters lower than that of their compatriots on the other side of the ocean.

The author's guess is that this is the result of the adaptation of food culture. Simply put, immigrants are eating more and more in the United States, and pickled foods such as kimchi are gradually withdrawing from the diet. Although this has brought obesity and diabetes to Asian immigrants, it has greatly reduced the incidence of gastric cancer. It can be seen how important it is to eat less high-salt and pickled foods to prevent gastric cancer.

Even if they don't go to work, many people don't eat on time. A survey of teachers and students in a medical college in Beijing shows that even medical students, even medical professors, often don't eat on time and eat irregularly.

Only 40% of teachers and students eat breakfast on time every day, nearly half eat it occasionally, and even one adult never eats breakfast. As for why they didn't eat, 80% of teachers and students said they were too busy to have time. It sounds quite helpless, maybe it's too much pressure to study. I don't have time for breakfast, but I have time for midnight snack. Nearly a quarter of teachers and students have the habit of eating midnight snack.

If you don't eat on time, it is your stomach that suffers. A survey of patients with chronic gastritis in three hospitals in Beijing shows that irregular diet is significantly related to six symptoms: abdominal pain, bloating, burping, nausea, acid reflux and heartburn.

If you know that you can't make three meals regularly, another habit that you may not notice at all is eating too fast. Eating too fast and not chewing enough will increase the digestive burden of gastrointestinal tract. The symptoms of acid regurgitation and burping in patients with chronic gastritis may be related to eating too fast.

So how fast is it to eat? A hospital in Shanxi has made statistics on the patients in this hospital. /kloc-about 40% of patients with gastric diseases eat within 0/0 minute, while the proportion of other patients who eat so fast is less than half of those with gastric diseases.

Irregular meals and fast meals not only cause various symptoms of the stomach, but also are possible risk factors for gastric cancer in China residents' eating habits.

In addition, few people cook by themselves when they go out, but when they eat out, they feel the risk of being infected with Helicobacter pylori.
