The most common autonomic symptoms that are reported are hypo or hyperhydrosis--disorders of sweating (and one of the most commonly used tests for autonomic small fiber involvement is the "sweat test"--sudomotor axon reflex testing), but there are a decent number who report some degree of orthostatic hypotension (blood pressure reduction on quick standing), and some even report problems with gastric emptying/motility/constipation.
Of course, gastric dysregulation is common in diabetes, in which the first nerves typically damaged are the small fiber ones; diabetic autonomic neuropathy is recognized as a specific clinical entity.

I agree on all points.
And although there are MANY causes of PN, Diabetic neuropathy and diabetic autonomic neuropathy are the most common causes of peripheral neuropathy.
