Colonoscopy. A flexible tube called a colonoscope is inserted through enlightened anus, rectum, and upper intestine, called the colon. Colonoscope transmits images from inside the rectum and entire colon.
Sigmoidoscopy. This procedure is similar to colonoscopy, but it uses a short tube called sigmoidoscope and transmits images of the rectum and sigmoid colon, the lower part of the colon, which empties into the rectum.
Barium enema x ray. A contrast material called barium is inserted into the colon to make it more visible in the raze- x.
simple diet and lifestyle changes often reduce the swelling of hemorrhoids and hemorrhoid symptoms improve. Eating a high fiber diet can make stools softer and easier to pass, reducing pressure on hemorrhoids caused by straining.
