Gestational Glucose Tolerance, 3 hour LabCorp

This test checks how your body processes sugar during pregnancy, helping to identify gestational diabetes which can cause symptoms like excessive thirst, frequent urination, fatigue, blurred vision, and sugar in urine.

Finding the cause(s) of:

• Blurred vision: High blood sugar levels from gestational diabetes can affect the fluid balance in your eyes, leading to blurred vision.
• Excessive thirst: High blood sugar pulls fluid from your tissues, making you feel very thirsty as your body tries to dilute the sugar.
• Fatigue: Your body struggles to use sugar for energy properly when blood sugar is high, leading to tiredness and fatigue.
• Frequent urination: Excess sugar in your blood spills into your urine, pulling water with it and making you need to urinate more often.
• Screening for gestational diabetes: This test is the standard way to screen for gestational diabetes, which is crucial for a healthy pregnancy.
• Sugar in urine: When blood sugar levels are high, the kidneys can't reabsorb all the sugar, causing it to appear in your urine.
