Preparation before colonoscopy

Nowadays, medicine is relatively developed, so many examinations can be done when the patient is alive. These examinations can see the specific conditions in the patient's body. This kind of examination is really helpful for treating some diseases. For those patients with serious gastrointestinal diseases, they generally need to do colonoscopy and gastroscopy. Both of these examinations are relatively complicated. So what preparations do you need to do before doing a colonoscopy?

There are many types of clinical examinations, such as laboratory examinations, pathological examinations, imaging examinations, and various endoscopic examinations. For patients with gastrointestinal lesions, commonly used examinations include colonoscopy, gastroscopy, capsule endoscopy, etc. in addition to routine laboratory tests. Before undergoing a colonoscopy, patients often need to make some preparations. So, what medicine do patients drink before colonoscopy?

Colonoscopy is an endoscopic examination that can visually see the condition of the patient's intestines. If polyps are seen under colonoscopy, they can be removed. Therefore, this examination is a frequently used examination method in gastroenterology.

The main area of ​​colonoscopy is the large intestine, where fecal residues are often found. If a colonoscopy is performed without any preparation, the food residue in the intestines will seriously affect the endoscopic field of view, making it difficult to clearly see the patient's intestinal condition. Therefore, before undergoing a colonoscopy, patients are required to take intestinal cleansing medications, such as mannitol, magnesium sulfate, polyethylene glycol, etc. In some cases, enema cleaning treatment is also required. These are all to ensure that the intestines are clean and to ensure the smooth progress of the examination.

The diseases examined by colonoscopy mainly include chronic intestinal inflammation, erosion ulcers, space-occupying lesions, etc. In addition to taking intestinal cleansing medications before undergoing colonoscopy, patients also need to fast to ensure the cleanliness of the intestines so as not to affect the examination results. Generally speaking, patients need to drink more water after taking the medicine, and when the substances discharged from the intestines become watery stools, it means that the work is almost done.

To sum up, the drugs that patients need to take before colonoscopy are generally drugs for cleaning the intestines, commonly known as laxatives, such as magnesium sulfate, polyethylene glycol, etc. This method can clean out food residues in the intestines and avoid affecting the examination results. In addition, patients do not need to worry too much before undergoing colonoscopy, just keep a calm mind. Generally speaking, colonoscopy is performed after anesthesia, takes a short time, and has little impact on patients.
