When it comes to eating, there are two main categories of people. The first category consists of people who love to eat, but once the food has been tasted and swallowed, the person does not really think about what happens to it afterward. Then, there are the people who are very concerned with the affects that the food they eat have on their body.
Regardless of which category a person falls into, once they reach the age of fifty and beyond, they need to have a virtual colonoscopy done as part of their overall healthcare regimen. Some people might just hear the word colonoscopy and try to avoid such a procedure. This is because they are thinking about the original colonoscopy, which was very invasive and had the potential for perforation in especially delicate patients.
However, the virtual colonoscopy has been designed to be a minimally invasive procedure. When a person is told that they need this preventative scan done, they probably know very little about why. In order to have an understanding as to why this procedure is so necessary to their overall health, they have to understand the digestion process itself.
When a person eats, they chew, swallow, and the food goes into their stomach. The stomach then uses digestive acids to break down the food. The food then passes through to the large intestine. During this time, the body is taking what nutrients it needs. The last stop for the food is the colon, which is also known as the small intestine. It is from the colon that the digested food is eventually excreted.
People who eat foods that are high in fiber at an advantage when it comes to colon health, because fiber is easily broken down by the body. However, people who eat foods like white bread and meat are at a disadvantage, because those kinds of foods take longer to digest, and can actually start rotting in the colon. This can lead to various colon problems. Once people reach middle age, they are also susceptible to cancerous colon polyps.
This is where the virtual colonoscopy comes in. This is an outpatient procedure, which means that although it might be done in a hospital, the patient will not actually have to stay in the hospital prior to or after having had the scan done. However, in the couple of days leading up to the procedure, the patient will have to only eat certain foods. The night before that actual procedure, the patient will have to drink a special liquid that will clear out any additional food particles in the colon.
The patient can wear his or her own clothing during the procedure, as long as it is free from any metal. Metal is something that throws off the scanning technology, so if the patient does not have clothing that is metal free, then he or she will be given a medical robe to wear during the procedure. It will take about fifteen minutes for the virtual colonoscopy itself, after which time patients can usually go back to their regular routine.
