What patient condition may lead to postponing surgery?

The presence of an active infection at the surgical site is a critical condition that warrants postponement of surgery. Surgical procedures require a sterile environment to minimize the risk of complications, including the risk of postoperative infections. If there is an existing infection, it indicates that the body is already dealing with a potential source of inflammation and may not be in a suitable state to undergo additional stress from surgery.

Performing surgery on an infected site could allow the infection to spread, complicate the surgical procedure, lead to poor healing outcomes, and significantly increase the risk of postoperative infections. Therefore, it is standard practice to ensure that any active infections are thoroughly treated and resolved before proceeding with surgical intervention.

In contrast, conditions like controlled hypertension, previous surgeries, and stable diabetes may require careful management and consideration but generally do not have the same immediate contraindication for surgery as an active infection does. Controlled conditions are often permissible for surgery, provided they are well managed.
