Integrating blood sugar discussions into routine eye care can deepen patient relationships, promote better metabolic health, and foster comprehensive disease management, says optometrist Abigail Hartle.
Talking to patients about blood sugar can do more than fill a gap in routine eye care. It can deepen trust, encourage more regular follow-up and create a broader conversation about systemic health, especially for people with diabetes or prediabetes. Abigail Hartle, an optometrist, argues that these discussions remind patients that their clinician is looking beyond the eyes and that simple, practical advice can make the subject feel more manageable.
That advice is grounded in basic physiology. Johns Hopkins Medicine has highlighted how often doctors fail to discuss hypoglycaemia, or low blood sugar, even though it remains one of the most serious treatment-related risks for people with diabetes. At the centre of blood sugar regulation is insulin, which helps move glucose into muscle and fat tissue and supports metabolic balance, according to NCBI’s overview of insulin action. When insulin no longer works effectively, glucose remains in the bloodstream for longer, contributing to insulin resistance and, over time, type 2 diabetes.
NCBI reviews of insulin resistance describe how the condition typically affects skeletal muscle, the liver and adipose tissue, leading to poorer glucose uptake and greater fat storage. That helps explain why blood sugar management is influenced by more than food alone. Sleep quality, stress, muscle mass and other individual factors can all affect how sharply glucose rises after meals. In that context, the goal is not perfection but steadier patterns and fewer large spikes.
Hartle’s practical suggestions focus on small changes patients may be able to sustain. Eating vegetables and protein before carbohydrates, choosing a salad or vegetable starter, and saving sweets for after a meal can all blunt a rise in glucose. She also points to the value of a protein-rich breakfast, fewer grazing-style snacks, light movement after eating and pairing carbohydrates with fat, fibre or protein. Some people also use vinegar or cinnamon, while leftovers such as cooled starches may contain more resistant starch, which is digested more slowly.
The wider point is that blood sugar conversations can be a useful part of routine care, not an optional extra. They give clinicians a way to connect eye health with broader metabolic health, while offering patients specific steps they can act on immediately. For practices, that can translate into stronger relationships, more consistent annual visits and more referrals. For patients, it can mean a clearer understanding of how everyday choices may affect both short-term wellbeing and long-term disease risk.
