Nasal polyp surgery is possible with diabetes, but the blood sugar status needs to be maintained at a stable state during the perioperative period. Nasal polyps are mainly soft tissue protrusions of the nasal mucosa caused by various reasons, which may lead to blockage of the nasal passages and cause obvious symptoms such as nasal congestion and runny nose, and can be treated with surgery. It is possible for diabetic patients to have nasal polyp surgery, but the perioperative period should be stabilized by controlling the blood glucose status, otherwise there may be infections, wounds that are difficult to heal, and other undesirable conditions that may affect the results of the surgery. When diabetic patients have nasal polyps, they need standardized treatment under the guidance of clinicians to avoid delays.
