Strange case of pre-diabetes, any thoughts?

I'm new to the Diabetes forum, but I frequent the Lyme Disease forum as I have that too.

I had a 2 hour glucose tolerance test done in April. The results were 9.9mmol/178. I asked for the test because I had symptoms of hypoglycemia. I was shocked at this result! My BMI is 18 and I'm 30, doesn't make sense.

Started seeing an Endo this month and she tested me for islet cell antibody (negative), C-peptide (1744), insulin random (284) and glucose random 9.8/176. This would suggest insulin resistance, right?

I also have frequent episodes of hypoglycemia going as low as 2.2/39. This usually happens 2-4 hours after my first meal. My fasting glucose is almost always 4.5 and my a1c is 5.4. My highest meter reading was 14.7/265

Now I'm experiencing pain on both sides under my ribs. Endo thinks it could be gallbladder/and or pancreas. She is scheduling me for an ultra sound to see if there's something going on there.

I'm wondering if anyone else has seen this in their case, or has heard of any others who might be experiencing this.

My Endo is baffled. She seems very commited to find out what is going on with me. I don't fit the profile of type 2 and I definitely don't have type 1.

I would've put money on being LADA, but my antibody test was negative. My Endo says that if it was type 1 or LADA, I would be producing a lot less insulin.

My Endo came very highly recommended, she has lots of experience. I became very freaked out when she told me that she doesn't see this!

I'm worried there might be an underlying condition causing my symptoms.

Does anyone else have reactive hypoglycemia with type 2? I have been able to manage the hypo with eating very frequently, but I will drop quickly if I don't eat.

I really appreciate any input, I'm really freaking out about this now!
