Brief Answer:
About diabetic neuropathy:

Detailed Answer:
Hello and thank you for asking!
There are some types of diabetic neuropathy; periferal neuropathy ( the most common) that is manifested with pain, numbness or feeling cold in the lower extremities and there is autonomic neuropathy.
The autonomic nervous system controls your heart, bladder, lungs, stomach, intestines, sex organs and eyes. Diabetes can affect the nerves in any of these areas, possibly causing:

-A lack of awareness that blood sugar levels are low (hypoglycemia unawareness)
-Bladder problems, including urinary tract infections or urinary retention or incontinence
-Constipation, uncontrolled diarrhea or a combination of the two
-Slow stomach emptying (gastroparesis), leading to nausea, vomiting, bloating and loss of appetite
-Hypotension and tachychardia. ect.

It can be fatal if very low blood sugar occur or if periferal neuropathy causes severe wounds otherwise it is not fatal.
Hope the information will help.
Best wishes,
