Treatment-Induced Neuropathy of Diabetes

Purpose of Review Treatment-induced neuropathy of diabetes ( TIND) is an under-recognized iatrogenic painful sensory and autonomic neuropathy. This review highlights the clinical symptoms and signs, raises awareness of the cause, and provides education about prevention of TIND. Recent Findings TIND may be triggered by a rapid decline in the blood glucose levels following the use of insulin, oral hypoglycemic medications, or even diet only to control diabetes. This may be seen in up to 10% of patients with diabetic neuropathy and has the potential for significant long-term complications that could be avoided through careful disease management. Based on the available evidence, a decrease in the glycosylated hemoglobin A1C of more than 3 points in 3 months in individuals with chronic hyperglycemia increases the risk of developing TIND. Summary TIND is more common than previously suspected, and is tied to rates of glycemic control. Slower changes to glucose control are suggested, although there is no prospective data on disease prevention. Future research is necessary to guide treatment recommendations.
