Explanation

"Flex Sig" is short for flexible sigmoidoscopy, a medical procedure used to examine the lower part of the colon, which is a part of the digestive system. During this procedure, a thin, flexible tube with a light and camera at the end is inserted into the body through the rectum. This allows doctors to view the inside of the colon to check for any abnormalities or issues. It's often used to help diagnose symptoms like abdominal pain, rectal bleeding, or changes in bowel habits.
