While WebMD makes no distinction between safe, or normal, glucose levels for men and women, target blood glucose ranges for optimum health may in fact vary by gender. Age can also be a factor in determining optimal levels.
A fasting blood sugar test measures blood glucose after the patient has not eaten for at least eight hours. The normal level for this test is less than or equal to 100 milligrams per deciliter of blood, states WebMD. However, women with Type 1 or Type 2 diabetes who become pregnant are advised to keep blood glucose levels in the 60 to 99 milligrams per deciliter range. Women with gestational diabetes should aim for 95 milligrams per deciliter or less.
The two-hour postprandial blood sugar test measures blood glucose exactly two hours after the patient begins eating a meal. Normal levels for this test range between 140 and 160 milligrams per deciliter depending on age, according to WebMD. Once again, lower targets apply to women with specific health situations. Women with Type 1 or Type 2 diabetes who become pregnant should target blood glucose levels in the 100 to 129 milligrams per deciliter or lower range. Women with gestational diabetes are advised to target 120 to 140 milligrams per deciliter or lower.
