During a colonoscopy, a long, flexible tube is inserted through your back passage to get a full view of your large intestine.
There are some warning signs that someone should have this test to rule out a major health condition like colon cancer, especially if they are older than 60.
Purpose of colonoscopy
Performing this test will primarily serve two purposes:
1 based on the clinical information you provided to your doctor
2 In order to screen
Given that colon cancer is the leading cause of death in Western nations and throughout the world, you should think about undergoing this test if you have chronic diarrhoea, altered bowel habits, unintentional weight loss accompanied by fatigue and sluggishness, Iron deficiency anaemia or a history of polyps that will be removed during this procedure and sent for a histo-pathological examination to determine whether they were benign or precancerous in nature.

Ideally, 90% of people who cross the age of 50 could have undergone this test in terms of screening in both males and females of average risk. If their prior colonoscopy revealed no issues, they will be given the opportunity to have one again in 10 years.
On the basis of your signs and symptoms, other tests, such as stool-based testing to check faecal occult-based tests, direct visualisation, such as flexible sigmoidoscopy, and other radiological tests, may also be carried out if you are between the ages of 50 and 75. But keep in mind that you can end up needing a colonoscopy to make sure everything is fine if any of these tests come up abnormal.
Now let's discuss those who are more likely to develop colon cancer in the future and may need to have a colposcopy after the age of 40 if they have a positive history of polyps, a family history of colon cancer, a personal history of colorectal carcinoma, or if they have Lynch syndrome, a genetic condition that increases a person's risk of developing cancer by 80 % or if they have inflammatory bowel disease.
Before colonoscopy
Everyone wonders why he or she should prepare their gut before visualising their gut, and this is a common question. The best way to ensure that you are prepared for a big bowel examination is to adhere to some particular guidelines that your doctor will give you.
A week before your appointment, they will send you a letter with all the necessary information to accomplish this. This could involve following a low residue diet that forgoes veggies, seeds, and dairy items a couple of days before this test. The key goal of the particular diet is this nothing should stimulate your stomach or linger in your system for an extended amount of time, much like veggies do.
Additionally, you must cleanse your intestines one day prior to the test by adhering to the clear liquid diet.
You'll need four litres of water, a laxative powder of your choosing (they come in a variety of flavours) and a lot of patience to complete the entire liquid to do this.
If you feel the need for something warm, you can also sip on clear chicken broth or you may have choice of drinking white grape juice, ginger ale, jell-o. Beware of drinking those fruit juices that contain pulp in it like orange juice.
One glass of water every fifteen minutes is a preference for some people, but this practise might overstuff the stomach and produce nausea and vomiting.
Avoid doing this and keep an eye on your preparation's end aim, which is to gain a clear picture of your intestine so that your doctor can assess it.
Others might choose for a split preparation strategy, where they complete half to two thirds of their gut preparation the day before the colonoscopy and drink a few glasses the morning of the test.
To feel comfortable on the day of the test, make sure you must complete your preparation at least 1 to 2 hours before leaving your home.
Please be mindful of what you are eating and drinking, as well as what you are passing, is another lesson to be learned from this article. You should be passing clear or light yellowish-tinged liquid from your back canal in order to gain the best visibility of your gut.
Other advice we can provide you, as you get ready for the colonoscopy is to make sure you have plenty of toilet tissues for your numerous trips to the bathroom and some books to read to pass the time. Other actions you can take to persuade yourself to drink that monotonous liquid include chilling it in the refrigerator or using a straw to drink it.
Last but not least, avoid using purple or crimson crystalloid powder as a laxative as it simulates blood pouring from your colon and could cause false positive findings and concerns for your doctor.
On the day of colonoscopy
A long, thin, flexible tube will be inserted through your anus during this procedure and up to the caecum. It has a front camera with a light, irrigation tubes for water to clean out any food particles still in your stomach, and air pumps to expand your intestines so that your doctor can see your gut as clearly as possible.
Additionally, the side channel for passing an instrument such as a wired loop or biopsy tool to obtain a biopsy if your doctor deems it necessary for you, as well as snares to collect a sample for a biopsy or to eliminate any polyps that may be present in your gut by burning them, is referred to as snare ploypectomy and later on the sent for examination to histo- pathological laboratory.

This entire procedure typically lasts between 30 and 45 minutes, but it will probably take at least two hours to get you to rest by giving you some sleep medicine and painkillers.
Your healthcare professional will advise you to unwind and lie on your side so they may easily bend the colonoscope in various directions. He will first press your abdomen, and then pump gas into it, which will make you feel a little, bloated or like you need to use the restroom. However, do not feel ashamed as your doctor anticipates that all of these things will occur throughout the operation. As was previously said, if a polyp is visible, it will be removed during the procedure and sent for testing to determine if it was benign or not.

| Procedure of colonoscopy |
If the colonoscopy results can be revealed during the procedure, your doctor will most likely be able to do so; if not, you will receive the letter two weeks later.
In order to wait for the sedation to wear off, you will be moved to the recovery room.
After the procedure you won't be able to drive owing to tiredness, therefore you must go with a family member or friend. Also, please avoid making any significant plans for the next 24 hours.
Complications of colonoscopy
In general, it is regarded as a safe procedure, although occasionally you can get a fever, light-headedness, or heavy bleeding. If that occurs to you, please see a doctor right away.
