<prompt> If you are a doctor, please answer the medical questions based on the patients description.I was on night shift for two weeks and this is my first week back on day shift I have felt dizzy and so tired and at every meal I get sick have thrown up once. I had three days to catch up on my sleep and everyday I feel more and more tired. I have hypoglycemia but I haven t gotten that checked in about 5 years.  <response>: Hi there... See first how can u see its hypoglycemia without even doing a sugar test... Hypoglycemia is said we blood sugar is less than 55 mgDL with symptoms like sweating palpitation tremors or sometimes if severe may lead to unconsciousness or convulsions. But usually it occurs in diabetic patients on medications. I think your symptoms are mainly due to disturbed sleep cycle. Though get your blood sugar and hemoglobin level checked. Take care.
