What Causes Increased Blood Sugar After Taking High Calorie Diet?

My boyfriends blood sugar on a good day is normally between 70-80. Sometimes after eating a large meal or one high in carbs it will spike up to 100 or more. He becomes very disoriented ,lightheaded, slurs his words and is very shakey. Sometimes it takes a few hours to get back to his NORMAL in the 70's. His doctors say that he isn't diabetic. They never see the spike and won't listen to him. What do you think the problem could be and what should we do to make them listen. He is a former combat medic and EMT. His doctors are at the VA clinic and they instantly discount him because it is always so low when he goes in for a check up.

Hi,

As you have mentioned Blood sugar levels of your boy friend, all Blood sugar level reading are normal, there is no evidence of diabetes.

For diagnosis of diabetes one of the following criteria need to be full filled
1) Oral glucose tolerance test
Fasting Blood sugar level more than 125 and/or 2hours post glucose blood sugar level more than 200.
2) HbA1c level more than 6.5.
3) Symptomatic for diabetes ie increased frequency of urination, unusual thirst, unusual hunger, weight loss, along with this random blood sugar levels more than 200.

Whatever symptoms mentioned by you like disorientation, slurred speech, abnormal shakiness, light headeness do not denote Diabetes.

Taking in to consideration of profession of your boy friend it looks like a possibility of anxiety.

Better to consult another doctor during period of symptoms or you can make video during symptomatic period.
