My doctor and I strongly suspect I have reactive hypoglycemia, and I have been following a no-sugar (as well as other adjustments) diet for about three weeks now. He has ordered a 5-hour Glucose Tolerance Test to confirm the diagnosis.
For this test, the lab gave me a three-day "loading diet" of things I must eat in the three days preceding the test. This diet includes sugar specifically (2 tsp/day) as well as potatoes, desserts, and other such foods, which I have been avoiding. I have never heard of this type of "loading" in relation to the GTT in what I have read.
Going off of sugar has not been easy for me. I've really struggled with severe fatigue and headaches, and from what I read, this is not uncommon and will pass. My concern is that three days on this prescribed diet will cause a setback--that is, will put me back to square one in the typical 3 to 5 week "feeling crummy" phase of a hypoglycemic diet.
Is this type of "loading" diet a necessary part of the GTT? Is it likely that three days of eating this way will mean starting over in the "gets worse before it gets better" process of a hypoglycemic diet?
Thanks so much.
