•Portion of the digestive tract between small intestine and anus•Approximately 1.5 m long •Consists of 6 sections:

• Cecum • Ascending colon• Transverse colon• Descending colon• Sigmoid colon • Rectum

Reabsorbs water and maintains the fluid balance of the body

Absorbs certain vitamins

Processes undigested material - Fiber

Stores waste before it is eliminated

The colon absorbs water from liquid stool that is delivered to it from the

small intestine

Connected to small intestine and anus

Hollow organ

The large intestine is a long hollow organ lined with mucous membrane

(mucosa). Muscle layers wrap around the entire length and help move food

material through to the rectum.

Irritable Bowel Syndrome (IBS)Irritable Bowel Syndrome (IBS) The most common functional disorder of the intestine. Functional

constipation and chronic functional abdominal pain are other disorders of the intestine that have physiological causes, but do not have identifiable structural, chemical, or infectious pathologies. They are aberrations of normal bowel function but not diseases.

Diverticular Disease Diverticular Disease Condition that is very common in older people in industrialized

countries. It usually affects the large intestine but has been known to affect the small intestine as well. Diverticular disease occurs when pouches form on the intestinal wall. Once the pouches become inflamed it is known as Diverticulitis, (or Diverticular disease.)

Endometriosis Endometriosis Affects the intestines, with similar symptoms to IBS.

Bowel twist (bowel strangulation) Bowel twist (bowel strangulation) Comparatively rare event (usually developing sometime after major

bowel surgery). It is, however, hard to diagnose correctly, and if left uncorrected can lead to bowel infarction and death. (The singer Maurice Gibb is understood to have died from this.)

Irritable Bowel Syndrome (IBS)Irritable Bowel Syndrome (IBS) No cure has been found for IBS, but many options are available to treat the

symptoms. Fiber supplements or laxatives for constipation or medicines to decrease

diarrhea, such as Lomotil or loperamide (Imodium). An antispasmodic is commonly prescribed, which helps to control colon muscle spasms and reduce abdominal pain.

Medications that relax muscles in the bladder and intestines, such as Donnapine and Librax.

A medication available specifically to treat IBS is alosetron hydrochloride (Lotronex).
