Dear madam i can understand your concern. with one random blood sugar reading its difficult to diagnose diabetes. i suggest you to check a test called Hba1c% for better analysis of the condition Hba1c% greater than 6.5% is considered as diabetes. i would like to tell you regarding diagnostic criteria of diabetes he diagnosis of diabetes requires one of the following: • A fasting glucose ≥ 126 mg/dL; • A hemoglobin A1c level ≥ 6.5%; • A random glucose level 200 mg/dL in a markedly symptomatic patient(symptoms like increased urination,thirst,weight loss,blurred vision and non healing ulcers. regarding neuropathy in diabetes. its a very late complication and seen in diabetes uncontrolled for a long time. its not expected in you vitamin b12 and vitamin D deficiency also which can give you the similar picture. go meet your gp and ask him for B12 and vit D testing. hope this explains regards Dr vamsi Diabetologist
