Dialysis Changes the Rules: What Happens When Patients With Diabetes Use Real-Time CGM?

Patient with Type 2 diabetes using real-time CGM while receiving maintenance hemodialysis.

Managing glucose is rarely simple for people with Type 2 diabetes who receive maintenance hemodialysis. Dialysis can change glucose patterns, insulin needs, and the reliability of familiar measures such as A1C. As a result, clinicians may have an incomplete picture when making treatment decisions. New randomized research on CGM use …

Two Shots a Year for Hypertension? How RNA Silencing Could Transform Cardiometabolic Care

RNAi hypertension diabetes therapy concept showing an investigational injection, blood pressure monitor, liver, heart, and kidneys.

Poor medication persistence remains one of the hardest barriers to long-term blood pressure control. For people with diabetes, the stakes are especially high because hypertension adds to cardiovascular and kidney risk. Now, research into RNAi for hypertension in people with diabetes is raising an intriguing possibility: could an injection given …

GLP-1s and Vision Loss: What Prescribers Should Know About the Emerging NAION Signal

Patient eye with semaglutide injection illustrating the potential GLP-1 NAION risk and sudden vision loss.

GLP-1 receptor agonists have transformed type 2 diabetes and obesity treatment, but a rare vision safety signal deserves clinicians’ attention. Emerging evidence has raised concerns about a potential NAION risk with GLP-1 therapy, particularly with semaglutide (Ozempic, Rybelsus, and Wegovy). Non-arteritic anterior ischemic optic neuropathy (NAION) can cause sudden, usually …

The Hidden Hyperglycemia Trigger: When Dehydration Makes Blood Sugar Worse

Person with diabetes reaching for water beside a glucose meter, illustrating how dehydration can worsen high blood sugar.

For people with diabetes, an unexpected glucose spike may have a less obvious cause than food or missed medication. Dehydration and high blood sugar can create a self-reinforcing cycle. When the body loses too much fluid, glucose becomes more concentrated in the bloodstream. At the same time, rising glucose can …

Your Eye Exam May Be Predicting More Than Vision Loss: AI Is Finding Hidden Diabetes Risks

Retinal AI analysis identifying cardiovascular, kidney, and metabolic risks in a patient with diabetes

For people with diabetes, a retinal photograph has traditionally answered one major question: Is diabetic retinopathy developing? However, artificial intelligence is beginning to uncover much more. Emerging retinal AI models for systemic risk assessment can detect patterns associated with cardiovascular disease, kidney disease, blood pressure, and metabolic health. As a …

LDL Is Under Control—So Why Is Heart Risk Still High? Solving the Lipoprotein(a) Puzzle

Lipoprotein(a) screening in diabetes showing a blood test, glucose meter, heart, and artery to illustrate residual cardiovascular risk.

For many people with diabetes, lowering LDL cholesterol is a major part of preventing heart attack and stroke. Yet an important clinical puzzle remains. Why do some patients experience cardiovascular events even after LDL reaches recommended targets? Growing evidence points toward lipoprotein(a), or Lp(a), as one possible piece of that …

The Biotin Blind Spot: How Everyday Supplements Can Skew Critical Diabetes Lab Results

High-dose biotin supplement bottle beside diabetes testing supplies, laboratory blood sample, and thyroid and cardiac lab reports illustrating biotin interference with diagnostic testing.

Biotin supplements have become increasingly popular among people living with diabetes. Many individuals take them to support healthy hair and nails, while others use high-dose formulations in hopes of easing neuropathy symptoms. An often-overlooked concern is biotin interference with laboratory tests used in diabetes care. Although biotin itself does not …

Rethinking Sugar-Free: Are Artificial Sweeteners Raising Cardiovascular Risk?

An anatomical heart model surrounded by erythritol, xylitol, stevia, and a blood glucose meter, illustrating the potential link between artificial sweeteners and cardiovascular risk in people with diabetes.

For years, artificial sweeteners have been promoted as an important strategy for reducing sugar intake in people with diabetes. They help lower carbohydrate intake, reduce post-meal glucose spikes, and support weight management without adding calories. However, recent research has challenged the long-held assumption that all non-nutritive sweeteners are metabolically neutral. …
