SBO stands for small bowel obstruction, which is a partial or complete blockage of either the small intestine or the large intestine. This condition is a medical emergency that requires immediate care, and it can be caused by various factors such as cancer, intussusception, gallstone ileus, and neoplasms. The symptoms of bowel obstruction include pain, vomiting, obstipation/absolute constipation, and distention. The management of bowel obstruction depends on the severity of the condition and may involve non-operative treatment or surgical intervention.

It is important to note that SBO can seriously impact the quality of life and health of the affected person. Therefore, it is crucial to seek medical attention as soon as possible if you experience any symptoms of bowel obstruction.

Apart from small bowel obstruction, SBO can also refer to a type of retirement savings plan called SBO 401(k), which is a tax-deferred, government-registered retirement savings plan designed for small business owners. Only businesses that employ the business owners and their spouses, and no other employees, are eligible for a SBO 401(k) . The contribution limit for a SBO 401(k) is $20,500 for 2022 (increasing to $22,500 in 2023), and catch-up contributions of up to $6,500 are allowed for those age 50 and above who have SBO 401(k)s (increasing to $7,500 for 2023) .
