Does Hypoglycemia Cause Severe Fatigue?

Glucose levels
Detailed Answer:
Sorry to learn about your bothersome symptoms.
Next time you feel off, please check your blood glucose levels with a fingerstick check using a glucose monitoring device. If the reading is less than 70 it is possible you have low glucose reactions called hypoglycemia.
When I see someone like you in my practice, I typically order the following blood tests in addition to a detailed physical examination:
CBC (Complete Blood Count, also known as Hemogram; includes Hemoglobin, WBC and Platelet counts)
Electrolytes (Sodium and Potassium in particular)
HbA1c (Glycosylated Hemoglobin = your last 3 months' glucose average). Also known by other names such as GlycoHemoglobin or Glycated Hemoglobin or A1c
Liver function tests (SGOT , SGPT, Albumin, Bilirubin, Alkaline Phosphatase)
Kidney function tests (BUN, Creatinine)
TSH (checks your thyroid)
25 hydroxy Vitamin D levels (ideal range 40 to 60 ng/ml = 100 to 150 nmol/liter)
None of these tests require any fasting and can be done at any time of the day
