A 60-year-old woman with type 2 diabetes mellitus complains of tingling in her feet. She also has a history of hypertension and high cholesterol. What could be the cause and what are the next steps?
The patient's symptoms are suggestive of diabetic peripheral neuropathy, a common complication of long-standing diabetes. Her high cholesterol and hypertension also contribute to the risk of developing neuropathy. Optimal control of her glucose, blood pressure, and cholesterol levels are key to managing her symptoms and preventing further progression. Regular foot care and potentially medications to manage the neuropathic pain could also be part of her treatment plan.
