Dear Dr. Motola,
Can sexual activity just before a PSA blood test make PSA results jump from 2 to 12?
PSA testing immediately after sexual activity remains controversial. The most widely held belief is that patients should wait 3 days after sexual activity prior to obtaining a PSA, however some recent studies suggest that sexual activity will not cause a rise. Repeating the PSA after 3 days of abstinence will be the easiest way to resolve this.
So you don’t have diabetes. Should you still be worried about having an elevated risk of Alzheimer’s disease? A new study out of the University of Arizona suggests that you could still have reason for concern.
The study looked at whether elevated blood sugar levels in people who do not have diabetes might indicate higher risk for developing Alzheimer’s disease. The link between diabetes and Alzheimer’s disease already has been studied.
The researchers used a specific type of positron electron tomography (PET) imaging technique to produce three-dimension images of metabolic activity in the brain. As part of the study, researchers used the PET imaging to look at fasting serum glucose (blood sugar) levels that study participants experienced after several hours of not eating.
The researchers analyzed data on 124 adults who were cognitively normal and did not have diabetes. Each of these participants had a family history of Alzheimer’s disease. They ranged in ...
I just saw the following question:
I recently had carpal tunnel surgery on both hands at the beginning of June. It's now late July and my blood sugar levels are still in the 230s. I take Lantus twice a day. What can I do? I have a constant headache, jaw pain, teeth hurt; can this be making my level stay high?
Something doesn’t quite fit together here. As I understand it, you have had elevated blood glucose levels continuously since hand surgery that was done almost two months ago.
Surgery certainly can cause pain, and pain is a stressor that can raise blood sugar levels. Plus, after most surgical procedures, there’s decreased physical activity for a while, which also would contribute to high sugar levels. With that in mind, I think people with diabetes who are on insulin shots or pumps should be given explicit instructions on what target ranges to aim for post-operatively, and how to adjust their insulin to meet these targets.
