I am 42 years old. I have had repeated constipation for seven or eight years. I have taken many kinds of medicines but it has been good and bad. Recently I went to the hospital to see a doctor. The doctor suggested to try biofeedback treatment. I want to know if this therapy works? —Ms. Song from Wuhan
According to the cause, constipation can be divided into three types: 1. Slow transmission type, mainly because the intestinal peristalsis function is weakened, and the stool runs too long in the intestine. 2. Outlet obstruction type, the rectum, anal canal and pelvic floor muscles are not working in harmony, the rectal propulsion is insufficient or the anal canal cannot be opened well during defecation, making it difficult to discharge stool. 3. Mixed type.
Different types of constipation have different treatment methods. Many people mistakenly think that laxatives are the cure for constipation. In fact, laxatives are not effective for exit obstruction. This is the reason why in daily life, some patients, especially those who are strenuous and time-consuming, have no effect even if they take laxatives. So, what treatment should be used for constipation patients with outlet obstruction? The answer is biofeedback therapy.
Human defecation actions are completed by the body's various systems. First of all, stool enters the rectum, causing mechanical expansion of the rectum. The rectum has a sensation of defecation, which is transmitted to the brain and adjusted by the cerebral nervous system. Abdominal pressure increases, rectal pressure increases and compresses the stool, and the external anal sphincter and puborectal muscles relax , The anus right angle becomes smaller, and the bowel movement is completed with the assistance of other pelvic floor muscles. However, for patients with outlet obstructive constipation, the bowel reflex, especially the function of the rectum, pelvic floor muscles, and anal canal loses coordination, resulting in insufficient rectal propulsion or poor anal canal relaxation during defecation. Simply put, the patient's bowel movements are not correct, and this error is often acquired, because some factors such as anal fissures, hemorrhoids or other reasons make the patient feel pain or discomfort during defecation, and then adjust the defecation state for a long time Instead, wrong bowel habits are formed.
With the help of professional instruments, biofeedback treatment can directly reflect the dynamic characteristics of the rectum and anal canal of the patient during defecation. Patients can see their real-time defecation status, learn, try, and adjust repeatedly, change bad defecation habits, and resume normal defecation movements. This method is not painful, safe, reliable, simple and effective, and the treatment can be stopped after the patient has restored the correct bowel movements.
