What is a complication that can occur after colectomy?

After a colectomy, a common complication that can occur is dehydration. This is largely due to the role the colon plays in water absorption. When a section of the colon is removed, the ability of the body to absorb water decreases, which can lead to fluid loss and dehydration. Patients who have undergone a colectomy may experience changes in their bowel habits, including increased stool frequency and looser stools, further contributing to fluid loss.

Maintaining hydration is essential after surgery, especially given the altered gastrointestinal function. Monitoring fluid intake and adjusting dietary habits can help mitigate this complication. By contrast, increased bile salt absorption, improved digestion, and reduced energy demands do not typically associate directly with colectomy effects and may not represent complications in a postoperative context.
