How Long Does A Colonoscopy Take?

A colonoscopy is a test to check the health of the colon (large intestine) and rectum internally using a flexible, long, and narrow tube known as a colonoscopy, which is inserted into your anus and then gradually into the rectum and colon. 

A colonoscopy test is conducted for several factors, such as regular check-ups for colon tumours and colon polyps (mushrooms like harmful tissues), to detect the problem beneath the abdominal pain and for diagnosis of bloody stools, to get rid of repetitive diarrhoea, or runny stools and familial history of colon diseases. Colon related diseases are more common in elders than in young adults so a person with the age of 45 or above should go for a routine colon check-up at least once a year. It is useful to detect tiny lesions or deformity which is less than 5mm in the size. It also evaluates and treats the conditions which are present at the end region of the gastrointestinal tract. 

Preparations for the Colonoscopy

The gastroenterologist will give you a specific diet plan, please inform your doctor if you are taking any kind of blood-thinning or diabetic medicines. At this point, the prescription of certain oral laxatives will be given to you. Be prepared for the liquid diet 1-2 days before the colonoscopy as a doctor will give you something similar. You will have to clean your colon entirely to achieve precise results, this should be done an hour before the test. Follow each and every guideline mentioned in a given paper or spoke by the doctor. Also, you can continue to take medications if that isn’t interrupting the colonoscopy test. Don’t eat or drink 4-7 hours before the test. But you should drink ample water before the procedure, to avoid dehydration. Before the procedure, you will be asked to change into the hospital gown. 

Procedure of Colonoscopy

The duration of the procedure varies from case to case but it is close to 30-45 minutes but come as early as possible and expect extra 1-2 hours for preparations and after test observation. A colonoscopy doesn’t demand overnight stay as it is a day procedure, on the basis of a person’s age and a health doctor will give an antibiotic. The technique is very less painful so there is no need to worry. An intravenous (vein injection) will be started for sedative by the anaesthetist, to ensure you are comfortable and relaxed. The patient’s oxygen level, blood pressure, pulse rates, and heartbeat will be observed through the monitor. A patient will lie on the left side or back and legs will be pulled upto your chest. Then colonoscope will be inserted gently through the anus and then to the large intestine, and it will be pushed till the end of the part of the small intestine and then it will be pulled back slowly. Sometimes suction is very helpful if there is some sort of waste material or liquid is stuck. Images will be clicked after blowing th air in the colon. If the test results aren’t appropriate additional tests will be conducted such as laser therapy. 

After Colonoscopy and Recovery

If a biopsy is combined with colonoscopy then results will take more than usual but otherwise, it doesn’t take much time. Once the result is in the gastroenterologist’s hand he/she will make you understand everything mentioned in the report. Then the nursing staff will take you to the monitoring room again everything will be examined. There should be someone along with you to drive you home. Also, avoid operating intense machinery for some days. Some cramping or pain is normal after the test but if you experience abdominal pain or bleeding, then urgently ask for medical help. Patients are allowed to eat normally and also drink more water to retain the lost water during the test.
