Living with prediabetes or type 2 diabetes? 3 areas to consider!

The Bottom Line

  • From vision loss to nerve damage, type 2 diabetes can negatively impact the entire body.
  • Professional gum disease treatment and dietary modifications can decrease blood sugar levels in people living with type 2 diabetes, while vitamin D supplementation may do so in people living with prediabetes.
  • Consult your healthcare team about actionable strategies for managing or preventing type 2 diabetes.  

Type 2 diabetes, which accounts for more than 95% of diabetes cases, impacts everything from our eyes to our nerves. Overtime, it can lead to vision loss, heart attacks, and even limb amputations (1). Prediabetes refers to a condition where there is higher than normal blood sugar levels and thus a higher risk of developing type 2 diabetes (2).


Given the effects of living with type 2 diabetes, it’s important to discuss considerations for management and prevention. Gum health, diet, and vitamin D are examples of three areas we should pay attention to (2-4). Click on the links below to learn more. 


1. Gum health

Diabetes and gum disease have a close relationship. Diabetes can increase the risk of developing gum disease and having gum disease can increase blood sugar levels. Blood sugar control is essential for diabetes management. Research shows that professionally delivered gum disease treatment can lower blood sugar levels for up to one year in people living with both diabetes and gum disease (3).  


2. Diet

People living with type 2 diabetes are twice as likely as those without diabetes to develop and die from cardiovascular diseases (5). Modifying one’s diet is a common strategy for managing and preventing chronic diseases. Research shows that after six months, the low glycemic index (GI) diet, Mediterranean diet, plant-based diet, high protein diet, low fat diet, and moderate carbohydrate diet can improve blood sugar levels and body weight in people living with type 2 diabetes. The low GI diet also demonstrates a significant reduction in the risk of experiencing major adverse cardiovascular events. More research on long-term impacts is needed (4).


3. Vitamin D

The relationship between vitamin D and diabetes has been an area of interest for scientific studies. Research shows that vitamin D supplementation at a moderate-to-high dose of 1000 IU or more per day may decrease the risk of developing type 2 diabetes in people living with prediabetes, and especially in those who are not classified as obese. Further research on how dosing and body mass index impacts benefits is needed (2).  


While these strategies provide some positive benefits, there is no ‘one size’ fits all approach, meaning they may not be suitable for all people. Consult with your healthcare team about whether these strategies are a good and safe fit for you based on your own needs and preferences. Together you can develop a more tailored approach.
