During the advancement process, a little gas will be released. Go to the focus point that needs to be observed, so that you can comprehensively and carefully check whether there is any problem in the intestines. So under what circumstances do you generally need a colonoscopy? Frequent intestinal discomfort

To know whether there are lesions in the large intestine, we must go through a colonoscopy to check clearly. Frequent constipation and diarrhea, if not due to bad food, are most likely caused by intestinal lesions. Intestinal lesions cannot be detected through other detection methods. Only colonoscopy can be used to check clearly what is wrong with the intestines. .

If unexplained constipation and diarrhea last for a long time, and the body becomes weightless, intestinal tumors or intestinal cancer may appear.

By the time the symptoms appear, they are already serious, so we must conduct a careful examination through colonoscopy. If early symptoms include blood in the stool, we will see what problems are occurring in the intestines and then provide targeted treatment. Frequent blood in the stool is a serious problem, so you must go to the hospital for detailed examination as soon as possible. How to do a colonoscopy and what it feels like?

For ordinary colonoscopy, the intestines must be prepared first and the intestines should be emptied. Then, before colonoscopy, you may need to inflate the intestines, and then go deep into the flexible endoscope and enter the colon through the anus.

There are currently two types of common colonoscopy, one is ordinary colonoscopy and the other is painless colonoscopy.

Both types of colonoscopy require a flexible instrument to be inserted into the intestine through the anus to check whether there are tumor lesions in the intestine.

Ordinary colonoscopy is a slender, flexible medical instrument with a diameter of about one centimeter. Through the anus of the human body, it enters the rectum and then to the large intestine. During this procedure, doctors can observe the inside of the colon and large intestine.

After a colonoscopy, you should eat some residue-free or semi-liquid diet with less residue for the first three days. You can eat fish eggs, milk, and soy products, but you should eat less fruits and vegetables. Stop taking iron medicines three days before the examination. You can take laxatives the day before the examination. The doctor will take castor oil orally on the day of the examination. It is best not to eat breakfast. To use colon cleansing solution, drink 3000 ml of colon cleansing solution within one and a half hours before the examination. If there is still fecal residue in the stool, you need to continue drinking the colon cleansing solution until the discharge is clear water.

After the intestines are cleared, the doctor will insert a curved visual instrument through the anus to examine the large intestine and rectum. There will be pain or swelling in the intestines and abdomen during the entire examination. Therefore, with this ordinary colonoscopy, the patient is awake throughout the entire process and feels more painful, but the diagnostic cost is cheaper.

The second type is painless colonoscopy. The preparation methods are relatively similar. Before performing a painless colonoscopy, adequate preparations must be made for the examination. First, the patient's physical condition must be assessed, whether the cardiopulmonary function can be tolerated, and if general anesthesia is available, preparations for bowel cleansing must be made the night before. The intestinal feces must also be cleaned with intestinal cleansing fluid that day.

Because the body needs to be inhaled and anesthetized with oxygen, the human body will not feel obvious pain during the entire colonoscopy process.

So whether it is painless or ordinary, the preparations before the examination are the same, including bowel cleansing. Painless only anesthetizes the body, so you will not feel fear or too much pain during the examination. Feel. But after finishing it, there will be gas in the intestines and slight flatulence.

Another type of colonoscopy is a capsule. Colonoscopy is also a mature medical instrument that uses a capsule shape to examine the intestines.

The doctor will make some preparations before the examination. For patients who are suitable for capsule colonoscopy, the doctor will ask the patient to swallow the capsule and then quickly take 50 to 100 ml of warm water. The doctor can check the condition of the intestines by connecting the capsule enteroscope to the instrument. After 6 to 8 hours of examination, the capsule enteroscope can be excreted from the body along with the patient's feces.

It is recommended that when you have obvious intestinal discomfort, you can choose to go to the hospital for a colonoscopy to see if there are any lesions in the intestines. The choice should be based on your personal physical condition.
