Wendi,
Generally, diabetes occurs when the pancreas is not producing enough insulin, or the insulin is 'defective,' which causes your blood glucose levels to shoot up.
I'm no doctor, but if your mom is producing *too* much insulin, she probably is dealing with something called hypoglycemia. That's fancy medical speak for chronic low-blood sugar. When your mom overproduces insulin, it may cause her glucose levels to crash, causing sweats, shakiness. Sometimes if things get really serious, it can cause fainting, incoherence, or unconsciousness. Usually a low-blood sugar episode can easily be avoided by drinking some juice or carrying glucose tablets with you.
There are tons of websites out there that can give you an idea about your mom's diagnosis. If you have any other questions about diabetes, or insulin, drop me a line.
Don't worry! Your mom will be just fine.
LIEP,
Maria
