Oh yes, triglycerides tell a story about sugar, as well as cholesterol. My glucose levels are always very good but for nerve health my integrative MD told me I should stop refined sugar, gluten and bad carbs. BOY did my next triglyceride etc testing come back good!
Learn all you can about your blood sugar and diet. Sugar/carbs are not good for the nerves and blood sugar, even if you have normal testing like me. It is great for everyone to have level blood sugar. Otherwise it is toxic to our nerves.
Good carbs are important but the processed ones, rice, potatoes,etc spike blood sugar.
Diet and supplements are really important.
I do think you are getting some good answers that will help.
