For colonoscopy, perhaps most people have personally experienced it, but some people hear that colonoscopy is needed, and the first reaction is rejection, after all, the colonoscopy that needs to be performed from a private part makes people feel very uncomfortable and embarrassed.
Why do I need a colonoscopy?
About 90% of bowel cancer is due to the evolution of intestinal polyps, it evolves from adenomatous polyps to cancerous, generally takes 5-10 years, if found and removed in time at the polyposis stage, is an effective way to prevent bowel cancer, and the best examination for finding intestinal polyps is colonoscopy.
Therefore, gastroenterologists with gastrointestinal discomfort generally recommend a colon study, especially for older people and people with intestinal symptoms.
How long does a colonoscopy last?
It is generally recommended that after a colon surgery, it can be re-examined after 3 to 5 years. Most intestinal diseases generally do not occur in a substantial lesion for 3 to 5 years, but patients should be treated promptly when inflammation occurs. For people with poor gastrointestinal function, it is recommended to do colonoscopy every 3 or 5 years to find out early in the treatment, which is conducive to good health.
Colonoscopy can not only determine whether it is inflamed, but also be able to observe the situation in the intestine to see if there is any abnormality, so for diseases in the colon, it is very necessary to do colonoscopy, if the disease in the intestine can not be treated in time, it may lead to colon polyps or bowel cancer, etc., by doing colonoscopy these can be found.
Most intestinal diseases go from normal mucous membranes to intrapopular neoplasia, which takes about 10 years, from polyps to cancerous changes, and then after another 10 years of disease development. Colonoscopy was done during this period, although no abnormalities were found, and a re-examination can be carried out in another 3-5 years. Therefore, for colonoscopy, it is generally possible to ensure that no more substantial lesions will occur in 3-5 years.
Although substantial lesions do not occur in the intestine for a certain period of time, other diseases such as colon inflammation, ulcerative colitis, and colon melanosis are not excluded. Therefore, it is recommended that those with a bad stomach and intestines recheck 1 colon every 3-5 years.
Why do most people not want to do "colonoscopy"?
Before the colonoscopy, the patient needs to prepare for intestinal emptying, which will determine the outcome of the examination and is also a must-do for colonoscopy.
Then when the anesthesiologist comes, the anesthetic is injected, and after the preoperative preparation is completed, the doctor slowly inserts the colonoscope from the anus, injects a small amount of gas, and then adjusts the corresponding angle to observe the intestinal lesions and begins to perform related operations.
The first point is that the colonoscopy needs to be entered from the anus, which is difficult for many people to talk about, and it will feel very embarrassing to do this examination, especially when encountering doctors of the opposite sex. Most people don't volunteer to go colonoscopy, which is an important reason why many people are reluctant to do it.
There are still many people who think that doing colonoscopy is very painful, in fact, now doing colonoscopy is not as painful as everyone thinks, now medical equipment is more and more advanced, as long as the doctor operates properly, colonoscopy will not bring some additional pain to patients, for those patients who need to do colonoscopy, to calm their minds, do not worry too much and do not listen to some rumors.
