Dear Doctor,
I recently had a 5 hour glucose test. I ate normally all week prior to the fast, and then fasted for 13 hours. (My normal diet is relatively low carb, but at least 150 to 200 carbs a day.)
There were six blood draws. My first blood draw at 9AM was 106; then I drank the glucose. The second draw was 193; third was 138. After the fourth at Noon, at around 12:15, I suddenly became dizzy and disoriented. I was shaking uncontrollably; sweating profusely. I bought water, and drank most of the bottle. As soon as I sat down, I fell asleep. I managed to wake up before my 1:00 test, and was no longer trembling so severely. I did not feel well at the 1:00 blood drawing. It turns out that at 12:00 just before this episode, the glucose level was 65, and at 1:00, after the episode, it was 64. ( By 2 PM it was at 79.)
I know that those levels of 65 and 64 are borderline hypoglycemic, and I feel that I was having a hypoglycemic reaction after 12:15 and before 1 PM. Is this normal? I have often had similar reactions three to four hours after eating. This is why I lowered my carb intake in 2004. However, I have never had a reaction this severe, with the profuse sweating, etc.
Could you tell me what this means in terms of the test?
