42 is young to have a problem like that so far advanced. High probability that there was a family history of colon cancer in this case.
Blood in the stool can be detected in many cases chemically using a stool sample put on a "card". Of course if you SEE blood in your stool or toilet paper have it checked out! Most likely hemorrhoids but could be rectal cancer. And don't use fancy toilet paper with colored flowers and such on it, you are less likely to miss any red color with white paper. Any change in "bowel habits" is another thing that should be checked out. Age 50 is the usual time to get a colonoscopy.
The prep is the worst part. If your going through with having a colonoscopy read the freakin instructions! You want your colon shinny clean
. NO fruits, vegetables, nuts or seeds a few days prior to the procedure. OK, so you gotta not eat the day before and then
, but that only lasts a few hours normally. You don't want an asteroid to hide a little polyp. The preps are easier if the day your going to drink it you drink a lot of water during that day. The preps take water out of you so if you start really really hydrated its easier for ya.
The drugs are great, many anesthesiologist use propofol and your out like a light and wake up so quickly, you wonder why all these people are in your bed room at home.
Sometimes the doctor will let you take pictures of you colon home just to prove to everyone your brains are not located there
