- Tested in people
This was tested in people. That is the most reliable kind of research we share.
This looked back at records of people who already had surgery, so it is early information.
The short version
People with diabetes had more fluid leaks after surgery for a pituitary tumor.
What was studied. Doctors in Taiwan looked back at records of 970 adults. All had surgery through the nose for a benign pituitary tumor between 2009 and 2019. Of those adults, 144, or 15%, had diabetes.
What they found. Diabetes was not linked to a longer hospital stay. It was also not linked to going back to the hospital within 14 days. But people with diabetes had higher odds of a spinal fluid leak. They were also more likely to need antibiotics for 7 days or more.
What this means, and what it doesn't
What it could mean: If you have diabetes and need this surgery, your team may watch you more closely. Blood sugar may matter for how you heal. It can help to ask your doctor about your blood sugar before surgery.
What it doesn't mean: This does not mean diabetes will cause problems for you. The study only looked back at old records. That kind of study cannot prove what caused what. The authors call these findings early and say bigger studies are needed. This is not a treatment, and it is not a cure. It is one piece of information about surgery risk.
