Constipation is a common problem affected by about 15% of the population, and patients usually diagnose and treat
In the past, the definition of constipation focused primarily on chronic constipation (CC), but in recent years there has been a growing recognition that Occasional Constipation (OC) is another subtype
The frequency threshold in the definition of chronic constipation is that patients have fewer than 3 bowel movements per
The term "OC" is derived from a panel of experts in the FDA's OTC Laxative Monograph, and "OC/Short-term Relief of Constipation" is an approved indication for many OTC laxatives
Therefore, this expert consensus recommends a practical definition of OC:
“
Intermittent or occasional symptomatic changes in bowel habits, including a decrease in annoying frequency and/or difficulty defecating, but without "alarm signs"
*Consensus emphasizes that patients who have blood in the stool, weight loss, or abdominal pain, or who have a personal/family history of colon cancer, or who have recently started taking new drugs that may be related to the onset of constipation symptoms should consult a physician
The consensus also states that since most OC patients do not attend the doctor, any management guidelines or recommendations should be disseminated through pharmacies and public channels and provide reliable information
.
Since the pathophysiology of OC is not fully understood, it is difficult to implement a "one-size-fits-all" algorithm
.
The table below summarizes the key knowledge gaps that remain today, and addressing them may contribute to the development
of future guidelines/recommendations 。 Compiled from: Rao S S C, Lacy B E, Emmanuel A, et al.
