I have never heard that high triglycerides could cause neuropathy, although I have read medical journal articles which indicate they can accompany some hereditary neuropathies. There is also a hereditary type of high triglyceride. As I have no other markers for heart disease and cannot take Tricor or statins I largely ignore my numbers beyond trying to watch what I eat and exercise as possible.

My triglycerides were well over 500, and fish oil has reduced them by nearly half.
