What complication can arise from a volvulus?

A volvulus, which is a significant twisting of the intestine, can lead to a number of serious complications due to the obstruction of normal intestinal flow. The primary concern with a volvulus is that it creates a blockage, resulting in intestinal obstruction. This obstruction can prevent the passage of contents through the intestine, leading to a buildup of food, fluid, and gas, which can cause severe abdominal pain, abdominal distension, and other gastrointestinal symptoms.

If not promptly treated, the obstruction can lead to ischemia (reduced blood flow) of the affected segment of the intestine, potentially resulting in tissue necrosis and perforation. These complications can be life-threatening, which underscores the critical importance of recognizing and addressing a volvulus in an appropriate and timely manner.

While the other options may be related to various medical conditions, they do not directly arise as a result of a volvulus specifically. For instance, excessive weight gain is not a complication associated with intestinal twisting, peptic ulcer disease relates to gastric conditions rather than bowel obstructions, and dehydration may occur as a consequence of a lengthy intestinal obstruction but is not the primary complication directly attributable to volvulus itself.
