More than 38 million Americans have diabetes, and another 97 million have prediabetes. The condition affects virtually every system in the body: cardiovascular, nervous, renal, and ocular. Yet diabetes management has improved dramatically with advances in continuous glucose monitoring, newer medications like GLP-1 agonists, and better understanding of lifestyle interventions.

This hub collects every diabetes-related guide on MDTalks. From the fundamentals of Type 2 diabetes to specific complications like diabetic neuropathy, each guide explains what AI health tools say about these conditions and how it compares to established clinical guidelines.

Frequently Asked Questions

What is a normal A1C level? A normal A1C is below 5.7%. Prediabetes is 5.7% to 6.4%. An A1C of 6.5% or higher on two separate tests indicates diabetes. See AI Answers: Diabetes.

What are the first signs of Type 2 diabetes? Increased thirst, frequent urination, unexplained weight loss, fatigue, blurred vision, and slow-healing sores. Many people have no symptoms in early stages, which is why screening is important. See AI Answers: Diabetes Type 2.

What are GLP-1 drugs and who can take them? GLP-1 receptor agonists (like semaglutide and tirzepatide) are medications originally developed for Type 2 diabetes that also cause significant weight loss. They require a prescription and are not appropriate for everyone. See GLP-1 Weight Loss Drugs 2026 Guide.

Can diabetes be reversed? Type 2 diabetes can go into remission with significant weight loss, dietary changes, and exercise, particularly when caught early. Type 1 diabetes cannot currently be reversed. Consult your healthcare provider about your specific situation.
