The Major Contributor To Diabetes We Don't Talk About Enough

The consequence is insulin resistance, which is when your body builds up a tolerance to insulin. In response, your body needs to produce more and more insulin to try to get the glucose in your blood into your cells. If your body can’t keep up and it develops insulin resistance, you get chronically high blood sugar or type 2 diabetes. 

The blood sugar problem in our country isn’t a secret. You’re probably already aware of the dangers of diabetes and what you need to do to prevent it. What isn’t common knowledge is the fact that blood sugar health is intricately connected to our gut and our stress levels.

Currently, there’s a great focus on high blood sugar being caused by too much sugar intake, but the truth is that the causes of diabetes are more complex than that and are intricately related to the gut and our stress levels.

Your gut health plays a key role in blood sugar regulation and insulin resistance.

A study from the Center for Individualized Medicine at the Mayo Clinic3 followed a group of 300 over the course of six days. The researchers tracked glycemic responses to foods and found that they could only accurately predict blood sugar between 32-40% of the time when they took into consideration simply what foods the subjects ate and how many calories they consumed. But when the scientists factored in the specific composition of the microbiomes of participants, they were able to accurately predict blood sugar response 62% of the time. 

Other studies also support the connection between blood sugar and the microbiome. Those who are overweight or have trouble losing weight—a symptom of underlying metabolic problems—tend to have lower4 microbiome diversity, with fewer beneficial microbes and more harmful bacteria and fungi.

In another fascinating study5, scientists were able to transplant the microbiome of diabetic mice into healthy mice to make them diabetic as well—without changing what the mice were eating at all. It’s also been postulated that changes in the gut microbiome lead to metabolic issues, which lead to a type of low-grade chronic inflammation that puts you at risk for obesity and diabetes.

These days, stressful events like family losses or trouble at work are well-known to be risk factors for triggering the onset of diabetes6. In addition, studies have shown that traumatic experiences, family chaos, and behavioral problems during childhood are also linked to diabetes7.

So what explains this connection? It turns out that the main stress hormone, cortisol, causes blood sugar levels to go up8. Technically, this is an evolutionary adaptation. When we’re trying to fight or flee, we need immediate sugar in our blood to fuel our muscles and cells to get out of a dangerous situation.

It, therefore, makes sense that when we encounter a threat, our body does what it’s designed to do, stopping digestion and other less critical bodily processes, like repair and cleanup mechanisms, and funneling its resources to the heart, brain, and muscles. The only problem occurs when stress is chronic. Too much cortisol for too long can lead to chronically high blood sugar, which can contribute to diabetes and insulin resistance. 

If you’ve got a blood sugar issue, I’m sure that your gut-feeling connection is playing an important role in your imbalance, and that healing will require an approach that tackles both the physical causes of blood sugar imbalances—such as gut microbiome imbalances and excess sugar intake—and the emotional ones, such as chronic stress or the effects of trauma.
