Once a diagnosis of pouchitis is made, the condition is further classified. The activity of pouchitis is stratified as:

- remission (no active pouchitis).

- mild to moderately active (increased stool frequency, urgency, infrequent incontinence).

- severely active (hospitalised for dehydration, frequent incontinence).

The duration of pouchitis is defined as acute (less than or equal to four weeks) or chronic (four weeks or more) and the pattern classified as infrequent (1-2 acute episodes), relapsing (three or fewer episodes) or continuous. Finally, the response to medical treatment as labelled as treatment responsive or treatment refractory, with the medication for either case being specified.

Pouchitis is inflammation of the ileal pouch (an artificial rectum surgically created out of ileal gut tissue in patients who have undergone a colectomy), which is created in the management of patients with ulcerative colitis, indeterminate colitis, FAP, or, rarely, other colitides.

A variety of pathophysiological mechanisms have been proposed for pouchitis, but the precise pathogenesis (biological cause) remains unknown. A pilot study on the effect of reducing dietary FODMAP intake on bowel function in patients without a colon ran by Croagh C, Shepherd SJ, Berryman M, Muir JG, Gibson PR indicates there might be a relation between Pouchitis and FODMAP content of diets.

The incidence of a first episode of pouchitis at 1, 5 and 10 years post-operatively is 15%, 33% and 45% respectively.

Patients with pouchitis typically present with bloody diarrhea, urgency in passing stools, or discomfort while passing stools. The loss of blood and/or dehydration resulting from the frequent stools will frequently result in nausea. Extreme cramping and pain can occur with pouchitis.

Endoscopy in patients with pouchitis usually reveals erythematous pouch mucosa, loss of pseudocolonic vasculature or other architecture, and friability of the mucosa. Biopsies show evidence of inflammatory cells or red blood cells in the lamina propria.

Surgery-associated ischemia may contribute inflammation at the anal transitional zone.

Patients whose cuffitis is refractory to mesalamine and/or corticosteroids should be evaluated for other disease in the cuff area, such as fistula or anastomotic leaks. Cuffitis that is refractory to medication can also be a sign of Crohn's disease of the pouch.

Chronic cuffitis can also contribute to the development of anastomotic stricture.

Cuffitis that is refractory, Crohn's-related, or is associated with surgical complications can contribute to pouch failure.

While IBD can limit quality of life because of pain, vomiting, diarrhea, and other socially undesired symptoms, it is rarely fatal on its own. Fatalities due to complications such as toxic megacolon, bowel perforation and surgical complications are also rare..

Around one-third of individuals with IBD experience persistent gastrointestinal symptoms similar to irritable bowel syndrome (IBS) in the absence of objective evidence of disease activity. Despite enduring the side-effects of long-term therapies, this cohort has a quality of life that is not significantly different to that of individuals with uncontrolled, objectively active disease, and escalation of therapy to biological agents is typically ineffective in resolving their symptoms. The cause of these IBS-like symptoms is unclear, but it has been suggested that changes in the gut-brain axis, epithelial barrier dysfunction, and the gut flora may be partially responsible.

While patients of IBD do have an increased risk of colorectal cancer, this is usually caught much earlier than the general population in routine surveillance of the colon by colonoscopy, and therefore patients are much more likely to survive.

New evidence suggests that patients with IBD may have an elevated risk of endothelial dysfunction and coronary artery disease.

A recent literature review by Gandhi et al. described that IBD patients over the age of 65 and females are at increased risk of coronary artery disease despite the lack of traditional risk factors.

The goal of treatment is toward achieving remission, after which the patient is usually switched to a lighter drug with fewer potential side effects. Every so often, an acute resurgence of the original symptoms may appear; this is known as a "flare-up". Depending on the circumstances, it may go away on its own or require medication. The time between flare-ups may be anywhere from weeks to years, and varies wildly between patients – a few have never experienced a flare-up.

Life with IBD can be challenging, however, it should not impede your ability to live a normal life. Patients with IBD can go to college, hold a normal job, get married, have children etc. As is the nature of any chronic, unpredictable disease, there will be ups and downs. The progress made in IBD research and treatment is astounding and will only improve in the years to come.

Although living with IBD can be difficult, there are numerous resources available to help families navigate the ins and out of IBD. The Crohn's and Colitis Foundation of America (CCFA) is an excellent resource. CCFA is a vital resource to getting questions answered and finding support about life with IBD.

IBD resulted in a global total of 51,000 deaths in 2013 and 55,000 deaths in 1990. The increased incidence of IBD since World War 2 has been linked to the increase in meat consumption worldwide, supporting the claim that animal protein intake is associated with IBD. Inflammatory bowel diseases are increasing in Europe.

Cuffitis is inflammation at the anal transition zone or “cuff” created as a result of ileal pouch-anal anastomosis (IPAA). It is considered a variant form of ulcerative colitis that occurs in the rectal cuff. Cuffitis is a common complication of IPAA, particularly when a stapled anastomosis without mucosectomy procedure has been used.
