Suffering from habitual constipation without treatment, harmful bacteria in the intestine will increase. Healthy people have the advantage of beneficial bacteria, but when constipation persists for a long time, the balance of beneficial and harmful bacteria will be destroyed. After eating too much meat, the protein in the feces will produce various toxins under the action of spoilage bacteria. These toxins circulate in the body together with the blood and can cause headaches, shoulder pain, high blood pressure and other symptoms. The most frightening thing is that the incidence of cancer has increased.
Eating a large amount of animal fats will cause the body to secrete a lot of bile, among which bile acids will become deoxycholic acid, lithocholic acid and other carcinogens after being broken down by bacteria in the intestine where the balance is disrupted. Carcinogens stay in the large intestine together with feces and stimulate the intestinal wall, which may cause colorectal cancer.
The morbidity rate and case fatality rate have gradually increased in China and the world, ranking high among the top ten common malignant tumors in China.
Colorectal cancer is divided into colon cancer and rectal cancer because of the different locations. In the past, there were quite a lot of patients with rectal cancer, but in recent years the prevalence of colon cancer has increased day by day, especially sigmoid colon cancer.
Symptoms of colorectal cancer: mostly occur in people aged 60 to 69, accounting for more than half of all patients, followed by 50 to 59 years old. In the past, male patients were the majority, but in recent years, female patients have gradually increased. The cure rate of early colorectal cancer is very high. Therefore, in order to treat it in time, it is necessary to have regular physical examinations.
Blood in the stool is the main symptom of colorectal cancer. Colorectal cancer is characterized by slow progress. There are almost no symptoms at the initial stage of symptoms of colorectal cancer, and it is difficult to detect. When symptoms appear, most of them have already developed to a certain degree. In addition, the symptoms also vary from person to person, and some people have no obvious symptoms even though they have developed to a considerable degree.
The most common symptom of colorectal cancer is blood in the stool. The cancer foci of the large intestine mucosa rubs with the stool and bleeds, so the stool will be mixed with blood.
If the tumor grows in the cecum or ascending colon near the small intestine, the stool will be black; if the tumor grows in the sigmoid colon or rectum near the anus, bloody stool will usually be discharged.
This is to be distinguished from bleeding caused by hemorrhoids. Bleeding caused by hemorrhoids usually separates the blood from the stool. The blood will drip drop by drop after defecation, and the wiped paper will be stained with blood drops. But colorectal cancer is blood mixed in the stool, so as long as you observe carefully, you will find the difference. However, it is difficult for ordinary people to distinguish it so clearly, so if you have any doubts, you should go to the hospital for examination.
In addition to bleeding, colorectal cancer also has abnormal bowel movements. If the stool is not discharged regularly, and there are abnormal conditions such as colic during defecation, it may be a tumor in the descending colon, sigmoid colon, or rectum.
Symptoms of colorectal cancer: If there is a tumor in the rectum, sometimes there will be a sense of disability after defecation; sometimes there will be symptoms such as continuous diarrhea and thinning of the shape of the stool; sometimes there will be round stools, but this is rare .
In addition, colorectal cancer sometimes suffers from persistent low-grade fever, anemia, sudden and obvious weight loss, conscious chest burning, lumps in the abdomen, swelling of the abdomen (feeling bloated, heavy and uncomfortable, obstructed, etc.), and part of the skin becomes dark and rough And other symptoms. Especially the elderly, if they have anemia of unknown cause, they should be alert to cancers of the digestive system including colorectal cancer.
