Introduction: The intestine is the largest digestive organ and detoxification organ in the human body. The intestine includes several parts such as the small intestine, large intestine , the anus, intestinal fluid , and intestinal flora .
The small intestine is an important nutrient absorption organ in the human body. Food is completed in the stomach and enters the small intestine after preliminary digestion, and is digested and decomposed in the small intestine. Most of the nutrients are absorbed through the small intestine, so the small intestine is the human body's nutrient absorber.
With the joint efforts of intestinal fluid, bile, pancreatic fluid , starch, protein , and fat in food are finally digested into sugars that the human body can absorb, amino acid , glycerol , fatty acids, etc.
The large intestine is the processing organ of feces. The large intestine receives the food residues after digestion and absorption by the small intestine, and then absorbs excess water, secretes some mucus, and makes the food residues form feces and are excreted from the body through the anal canal. Therefore, the large intestine is the processing organ of the residue. The large intestine has the cecum, appendix , colon , rectum, etc.
In addition, the intestine is also an important immune organ in the human body. Nearly 70% of immune cells are distributed on the intestinal mucosa, and they are responsible for more than 70% of the immune function of the human body. They play an important role in maintaining the stability of the intestinal environment below bacteria and viruses.
As we all know, as the saying goes, disease enters from the mouth. If you do not pay attention to healthy diet, it will be harmed by bacteria and viruses, and inflammation will occur, which will also cause a series of rectal diseases, such as rectal polyps , ulcerative colitis, intestinal adenomas, etc.
causes damage to the intestinal mucosa and lead to rectal lesions.
, especially the intestinal cancer we often call, is also a disease that is now highly prevalent. Once intestinal cancer occurs, it will seriously affect daily work and life, physical and mental health, and it is ultimately safe in life. Therefore, this reminds everyone that you must pay more attention in your daily life.
What is bowel cancer?
Intestinal cancer refers to malignant tumors that occur in the small intestine, colon and rectum. Common malignant tumors in the small intestine include malignant lymphoma , adenocarcinoma, leiomyosarcoma and carcinoids. Among them, adenocarcinoma can grow into the intestinal cavity in a polyp-like shape, and may infiltrate the intestinal wall, causing intestinal stenosis.
colon cancer is a relatively common malignant tumor in the digestive tract. According to the histology types, they can be divided into adenocarcinoma, mucinous carcinoma, and undifferentiated carcinoma. Among them, adenocarcinoma is the most common, while undifferentiated carcinoma has the worst prognosis.
rectal cancer is related to diet such as high-fat and high-protein foods, chronic inflammation, precancerous lesions , etc., and histological typing is similar to colon cancer.
When there is a problem with the intestinal tract, the body may experience 5 "changes"?
The number of bowel movements increases:
Normal people give stools one or two times a day. If there is a problem with the intestines, such as Enteritis or malignant lesions, the number of bowel movements will increase.
Blood stool :
In addition to hemorrhoid can cause bloody stool, some intestinal diseases such as intestinal cancer can also cause bloody stool.
Constipation or diarrhea:
Intestinal problems can lead to abnormal bowel movements, sometimes constipation, sometimes diarrhea, and sometimes these two symptoms will alternate.
Exhaust gas is very smelly:
Intestines, there is a problem with the intestine. The bacteria in the intestine will be unbalanced, and the harmful bacteria will increase a lot. These bacteria will produce a lot of vulcanized gas in the intestine, causing the exhaust to be smelly.
bad breath:
0 Intestine problems can also lead to bad breath. This is because abnormally fermented gas in the intestines will circulate to the lungs through the blood, and breathing will lead to bad breath.
Reminder: Try to do these 3 points as well as possible
Diet prevention
Too little fiber in food will also increase the probability of colorectal cancer.
A large-scale survey on diet and cancer involving 400,000 people at the University of Cambridge in the United Kingdom showed that a high-fiber diet can effectively reduce the risk of cancer by 40%, especially colon and rectal cancer.
With the change of the dietary structure of Chinese people, high-protein, high-calorie, and low-fiber diet habits have increased the occurrence of colorectal cancer. The foods eaten are too fine and delicate, which can easily cause constipation. If the stool stays in the intestine for too long, the toxins will be more easily absorbed by the intestine, thus causing colorectal cancer.
Therefore, it is necessary to reduce the intake of fine foods, eat more crude fiber foods, reduce the intake of red meat and processed meat, and eat more fruits and vegetables, which can prevent colorectal cancer.
Develop regular bowel habits
People need to maintain regular bowel habits to prevent colorectal cancer. They can clean up garbage and waste in the intestines as soon as possible to reduce damage to the intestines.
If people's constipation symptoms do not improve for a long time, it is easy to cause garbage in the feces to irritate the intestinal mucosal tissue, which will also increase the risk of colorectal cancer.
Therefore, people need to maintain regular bowel habits to help avoid colorectal cancer.
Regular screening and physical examination
Last, and most importantly, regular physical examinations, early detection and treatment of early cancer or precancerous lesions.
WHO recommends that people aged 45 to 74 undergo occult blood tests every two years. People over 40 years old should undergo colonoscopy once every five years.
If you have inflammatory bowel disease (including ulcerative colitis and Crohn's disease ), colorectal adenomatous polyps, and hereditary colon cancer, it is best to undergo colonoscopy once every 1 to 2 years.
Conclusion: In summary, prevention is divided into three aspects
First, it is to remove polyps from the large intestine as early as possible;
Second, be vigilant about hereditary colorectal cancer;
