I believe many friends are no strangers to Helicobacter pylori. What is your impression?
A friend said: it is related to the occurrence of many diseases in the stomach, and it is a bad bacterium.
Then today we will talk to you about some new things of this ancient bacterium.
Genetic analysis shows that people have been carrying Helicobacter pylori for more than100000 years.
This is a long-term cooperative relationship, and everyone has it.
After the 20th century, Helicobacter pylori began to disappear from people's stomachs, but the research on it became deeper and deeper.
Is helicobacter pylori harmful to humans?
Dr Warren and Dr Marshall are two big names in the field of Helicobacter pylori research. Their research shows that Helicobacter pylori can cause gastric ulcer and gastritis.
Dr Blazer of the United States followed up and analyzed the correlation between blood samples of 7400 veterans and gastric cancer. The results showed that in the next 2 1 year, people with Helicobacter pylori were 6 times more likely to develop gastric cancer than those without Helicobacter pylori.
Therefore, Helicobacter pylori is involved in the occurrence of gastric cancer.
1994, the world health organization listed helicobacter pylori as a primary carcinogen, and its relationship with gastric cancer is as unquestionable as that between smoking and lung cancer.
So: Doctors all over the world are beginning to believe that Helicobacter pylori is harmful to human beings.
Once found, kill them with antibiotics.
The other side of helicobacter pylori
After reading this familiar side, let's look at the other side of Helicobacter pylori.
Some data to share with you: gastroesophageal reflux has increased since 1930, and Barrett's reflux disease is more serious and rare.
It has been increasing since 1950, while the shocking lung adenocarcinoma has been increasing since 1970, with a six-fold increase in the past 30 years.
Is there a necessary connection between these?
Let's talk about gastroesophageal reflux first.
If gastroesophageal reflux occurs occasionally, it is not a big problem in itself, but if it becomes a chronic disease, it will be troublesome to get gastroesophageal reflux disease (GERD).
This disease afflicts you every day. In addition to heartburn, acid reflux and chest tightness, you will feel sick and have difficulty swallowing.
Gastroesophageal reflux is now one of the fastest growing diseases in developed countries.
In the United States, for example, 10% ~ 20% of adults suffer from this disease.
If gastroesophageal reflux is not treated in time, it will lead to tissue damage (Barrett's esophagus) and gradually deteriorate into lung adenocarcinoma.
Why is gastroesophageal reflux suddenly popular?
Dr blaser himself is an expert on helicobacter pylori.
When he tested himself, he found that there was Helicobacter pylori in his stomach, so he naturally began to take antibiotics and constantly detected the number of Helicobacter pylori.
As a result, as he expected, the number of Helicobacter pylori decreased sharply, and he could breathe a sigh of relief. After all, the chances of getting gastric cancer are greatly reduced.
But something strange happened, and he began to have heartburn and nausea.
This made him wonder whether the appearance of gastric reflux was related to the disappearance of Helicobacter pylori.
Scientists have found through a large number of studies that Helicobacter pylori is negatively correlated with gastroesophageal reflux, Barrett's esophagus and lung adenocarcinoma.
In other words, the fewer helicobacter pylori, the greater the chance of suffering from these diseases.
Asthma and Helicobacter pylori
Dr Rebmann, a respiratory expert, analyzed 365,438+08 asthmatic patients and 208 healthy people. The results show that people with Helicobacter pylori are 40% less likely to develop asthma.
Dr. Rebmann also found that the average age of people with Helicobacter pylori suffering from asthma is 265,438+0, while the average age of people without Helicobacter pylori suffering from asthma is 65,438+065,438+0.
A large experiment involving 7600 people in 2006 found the same negative correlation.
Interestingly, this association only occurs in children below 15.
Allergic rhinitis and Helicobacter pylori
A strong correlation between Helicobacter pylori and allergic rhinitis was also found in children with allergic rhinitis.
Gastroesophageal reflux, asthma and allergic rhinitis, three common but unrelated diseases, are all related to Helicobacter pylori. What is the mechanism?
Now there is a theory that Helicobacter pylori plays a role in asthma and allergic rhinitis by affecting regulatory T lymphocytes.
Is helicobacter pylori good or bad?
Answer: Double-sided.
The main purpose is to let everyone know the importance of balance.
In fact, many microorganisms and important substances secreted in our bodies are like this, and it is not good to be indispensable or excessive.
Everyone is unique. If you belong to the high-risk group of gastric cancer, it is natural to give priority to reducing the risk of gastric cancer.
Under normal circumstances, as long as it is in a balanced state, there is no need to deliberately eliminate it: if you find yourself positive for Helicobacter pylori and are worried about getting gastric cancer, use antibiotics immediately.
I remember that Helicobacter pylori is an old friend of mankind. If you overdo it, there are many natural treatments, including adjusting your diet, which can keep it within a certain range and will not harm us. Let's live in peace!
