Defecation is 'hard in the front and soft in the back'. If accompanied by these 4 conditions, it may be that bowel cancer wants to get close, don't ignore it
Human's daily nutritional intake comes from "food", so Chinese people have also developed the habit of "three meals" since ancient times. However, the ingested food is not completely digested and absorbed by the body, and the remaining food residues will accumulate in the colon one after another, waiting for the final processing of the rectum, and the stool formed first will continue to accumulate in the rectum. When a sufficient amount is accumulated, the meaning will come.
In general, the formation of stool is entirely due to the "gut", and some friends in life have the symptoms of "dry before and after the stool". In fact, this is mainly because the stool at the front end has been formed for too long, and the water is again absorbed by the intestinal mucosa, thus forming a dry and hard part. And the later stool has not had time to be absorbed, it is excreted from the body along with the stool, thus forming abnormal stool;
On the other hand, the formation of stool is also affected by food, such as excessive intake of high-fat, high-protein food, it is not easy for the body to fully absorb it, thus forming a chyle-like food residue. Eating too much high-fiber food on the first day and eating high-fat and high-protein food on the second day will also lead to a dry and hard head and a soft and sticky back.
In addition to dietary effects, bowel disease can also affect stool status. Especially recently, the feeling of "tenesmus" has often appeared. It is obvious that the bowel movement is very urgent, but it cannot be discharged smoothly, and there is a situation where the front is hard and the back is soft, which may be a disease of the intestines. Especially when accompanied by the following four symptoms, it is necessary to be alert to the occurrence of colon cancer:
Changes in bowel habits: When adults are healthy, they will develop their own bowel habits, which can even be fixed to a certain period of time. For example, the bowel movements after getting up early every day are their own bowel habits. However, if there has been a significant change in bowel habits recently, especially multiple bowel movements in one day, and there is no relief for more than two weeks, this may be caused by the stimulation of the intestine by cancer;
Changes in the shape of the stool: In addition to the stool being hard and thin before the stool, if the shape of the stool changes, it may also be caused by cancer in the body. Especially after the rectum becomes cancerous, not only the storage space of feces will be reduced, but at the same time, when the feces pass through, the cancer can also squeeze the feces, resulting in the feces showing a flat strip-like and thin strip-like state. If the stool is too dry, it can also cause surface bleeding while rubbing against the cancer, resulting in blood stains on one side of the stool;
Black stool: The pigment in food does temporarily change the color of stool. For example, eating too much chocolate can make stool appear black. However, if the stool is not only black, but also has an oily surface and a strange fishy smell, this may be a manifestation of gastrointestinal bleeding. Especially in the bleeding caused by cancer in the colon, the blood is oxidized in the intestine, and the combination of hemoglobin and sulfide will lead to the appearance of black stool, which is clinically called "tarry stool";
Painless blood in the stool: During the process of defecation, it is found that the blood and the stool are mixed together, showing a dark red color, or the mucus-like bloody stool is directly discharged, and there is no severe pain in the anus, which may be cancer. caused. The presence of mucoid blood in the stool often also marks that the colon cancer has developed to the middle and advanced stage.
Bowel cancer is a high incidence of digestive tract cancer in recent years, especially people over 45 years old, people with a family history of bowel cancer, and a family history of adenoma have a higher risk of bowel cancer. Although the above symptoms are all manifestations of bowel cancer, there are also many patients with bowel cancer in the early stage, and there is almost no abnormality in the body. Therefore, regular physical examination is the main method to detect colorectal cancer, especially for high-risk groups, and physical examination cannot be ignored.
