Changes in bowel habits

Introduction The stool time changes and the stool is irregular. The habit of defecation is generally related to the individual's biological clock, the habit of personal diet, should pay attention to adjust the diet, ensure sleep, exercise more. Long-term irregular diet can cause "Irritable Bowel Syndrome". If the course of the disease has been relatively long (more than half a year), this may be "Irritable Bowel Syndrome". This is a functional lesion of the colon, mainly manifested in the absence of stool, increased frequency, abdominal distension and so on.

Cause

Large intestines are divided into cecum, ascending colon, transverse colon, descending colon, sigmoid colon, rectum, anal canal, etc., and tumors can be seen in all parts. In the entire colon, cancer occurs in approximately 50% of the rectal or rectosigmoid junction. Primary rectal cancer mainly relies on occult blood test, anal finger diagnosis, rectal sigmoidoscopy and biopsy diagnosis. Barium enema is used in the sigmoid colon and is rarely used in the rectum. Taking rectal cancer as an example, the initial diagnosis is often a change in bowel habits and fecal properties: frequent frequency, mucus, diarrhea accounted for 67.5%, blood in the stool 65.2%, anal pain, urgency, constipation, abdominal pain is not uncommon. The lesions continue to progress, and the daily platoon can reach more than 10 times, and there is a continuous urgency and heavy sequelae, and even the anal incontinence flows out of mucus and malodorous pus. When the tumor is deeper and the infection is heavier, there is severe pain in the area and often anemia. When the tumor develops into the intestine for one week, the intestinal stenosis is caused, and the number of initial bowel movements increases, but the amount of feces is small, or it is a thin flat shape, or a bloody mucus, and intestinal obstruction occurs when the stenosis is heavier.

Repeated (at least 3 times) routine stool culture were negative, the occult blood test was negative, normal hematuria was normal, and erythrocyte sedimentation rate was normal. For patients over 40 years old, in addition to the above examination, colonoscopy and mucosal biopsy were performed to exclude the intestine. Infectious, neoplastic diseases, etc.

Differential diagnosis

Hemorrhoids: Acne is a disease that everyone is familiar with, and the incidence rate is also very high. It is said to be "ten people and nine people." It refers to one or more soft veins formed by the varicose veins of the mucosa at the base of the anus and the mucosa around the anus. The main symptom is blood in the stool. If there is a blood clot, pain will occur. Similarly, the enlargement of the nucleus can cause the stool to become thinner. Hemorrhoids hemorrhage is caused by the stool around the anus around the anus. The blood is dripped with the stool and the blood is mostly mixed with blood. The blood and feces are not mixed, and most of them have no mucus adhesion.

Rectal cancer: occurs in people over 40 years old. There are often no obvious symptoms in the early stage. The stool of patients with rectal cancer is often accompanied by blood, mucus, adhesion to the concentrated liquid, and changes in bowel habits, alternating diarrhea and constipation. The number of stools is increased, it is fine, the anus often has irritation, and often wants to have a bowel movement. Patients with rectal cancer also have systemic changes, such as significant weight loss and anemia in the short term.

Rectal polyps: refers to the bulging lesions that protrude from the surface of the rectal mucosa to the intestine, including adenomas, inflammatory polyps, and polyposis. From a pathological point of view, the content is different, some are benign tumors, and some are the consequences of inflammatory hyperplasia. The blood in the stool is blood and is covered on the surface of the feces without mixing with it. The pedicled polyps at the lower end of the rectum can be removed from the anus. When polyps are combined with ulcer infection, there may be mucus and bloody stools and a sense of urgency.
