Observe the bowel movement from three aspects
Professor Chen Yuzhong introduced that changes in bowel habits include three aspects:
Stool is the residue left by the digestion and absorption of food, which enters the rectum through intestinal peristalsis. The baroreceptors of the rectum cause bowel movements, which are manifested as fullness of the lower abdomen and distended anus. This sensation disappears after the stool is discharged from the body.
The number of bowel movements per day is 1 to 2 for normal adults, and once every other day for a few people. Defecation less than 2 times a week should be considered constipation. Compared with the original bowel habit, you have to be careful when you have sudden excessive bowel movements or longer intervals.
Mainly refers to dry and thin feces. Usually formed soft stools, occasionally dry or loose stools are also normal, often related to dietary activities and mental factors.
Unexplained changes in stool are a wake-up call
Professor Chen Yuzhong reminded that changes in bowel habits without obvious triggers should also be regarded as a wake-up call for colorectal cancer. Increased frequency of uninduced defecation, whether dry or loose, if accompanied by incomplete defecation, it means that the pelvic floor and rectal nerve and muscle are stimulated. At this time, if there is blood or mucus in the stool, you should go to the hospital in time. Anal examination or colonoscopy can rule out the colorectal tumor disease. It must not be regarded as a hemorrhoid attack and delayed treatment.
According to literature, about 30% to 80% of patients with rectal cancer are misdiagnosed as internal hemorrhoids or dysentery before diagnosis. Changes in bowel habits are an early sign of colorectal cancer. Patients with colorectal cancer who are detected early and treated in time have a 5-year survival rate of more than 90%; the survival rate of surgical treatment for advanced patients is only 30%. Surgery is the only way to have a chance to cure colorectal cancer. Early colorectal cancer should be treated with radical surgery in time, with traditional Chinese medicine treatment after surgery, which has a higher radical cure rate; patients with advanced colorectal cancer have the opportunity to remove the original After the onset, combined with radiotherapy and chemotherapy and Chinese medicine anti-tumor therapy can also prolong survival.
In addition, pay attention to the following points in the prevention of colorectal cancer: try to avoid "three highs and one low" foods in the diet, that is, high-fat, high-protein, high-calorie, and low-fiber foods. Avoid excessive intake. Mixed and wide, don't have a partial eclipse Moldy peanuts, sauerkraut, salted fish, sausages and other pickled products and smoked products should not be over-eaten; develop good living habits, do not smoke or drink alcohol.
