Last week I had a relatively simple laser procedure in the office to break through the capsule and get rid of the scar tissue from a previous cataract surgery. The doctor advised me to see my family physician because he saw changes in the eye that could indicate diabetes.
Yesterday I had my first ever 3-hour Glucose Tolerance Test. The first fasting reading was 100. Then I drank the "sugar water." It reminded me of Orange Crush pop, but was sickeningly sweet. She told me it has 75 grams of sugar. If I entered the figure right in the calculator converter, that's the equivalent of 2/3 cup of sugar. No wonder I felt sick. She said some people complain of it feeling heavy and they feel better when they burp. That helped a little, but I felt nauseous and headachey.
She drew blood two more times the first hour, half hour apart, after the nasty drink. Then I could leave and come back at one hour intervals for another blood draw. The final reading was 70.
MEDLINE PLUS says: Normal blood values for a 75-gram oral glucose tolerance test used to check for type 2 diabetes in those who are not pregnant:
•Fasting: 60 -100 mg/dL
•1 hour: less than 200 mg/dL
•2 hours: less than 140 mg/dL
I have to wait for the official reading but I'm guessing this means I've dodged the bullet again. Any comments from Spark Friends who know about GTT test readings?
By the last blood draw, I was starting to feel like myself, except for the headache that stayed with me the rest of the day, resistant to Tylenol. A late afternoon nap helped.
What did I learn from this? I would NEVER voluntarily eat something that sweet. The rest of the afternoon I avoided with horror anything even the tiniest bit sweet.
Mountain Dew is high in sugar. The Internet tells me there are 75 grams in a 20 ounce bottle. That puts it is perspective. I rarely drink pop, but Mountain Dew is one my favorites. It doesn't taste as nasty as the "sugar water" for the GTT test because it's not as concentrated and has much more carbonation. Still, I think I will give it a pass. I really do find our county well water very refreshing.
I am thankful that diabetes does not run in my family, perhaps banking too much on family "immunity." I know that's not how it works. People get diabetes who seem perfectly healthy and do not have diabetes in their family. Three of my closest friends and one sister in law are insulin dependent.
It strikes a little dread in me when doctors even suggest it. From time to time, one doctor or another will order an HGB A1C which always comes back negative for diabetes. I've dealt with so many medical issues in the last ten years, that I know I would handle this in the same manner once the shock wore off.
That's the second health scare I've had this year. Maybe I need to be a little more consistent in doing the things that result in optimal health.
