Prediabetes and Chronic Stress: How Cortisol May Affect Blood Sugar

Prediabetes is one of the most important warning signs for long-term metabolic health. It means blood sugar levels are higher than normal, but not high enough to be diagnosed as type 2 diabetes.

Many people think of prediabetes as “not serious yet,” but it deserves attention. Prediabetes can increase the risk of developing type 2 diabetes, heart disease, and other health concerns over time.

Lifestyle factors such as nutrition, physical activity, sleep, weight, and stress management can all play an important role in supporting healthy blood sugar levels.

What Is Prediabetes?

Prediabetes occurs when the body has difficulty keeping blood sugar within a healthy range. This may happen when the body becomes less responsive to insulin, the hormone that helps move glucose from the bloodstream into cells.

A commonly used marker for prediabetes is hemoglobin A1C. An A1C between 5.7% and 6.4% is generally considered prediabetes.

Because prediabetes often has no obvious symptoms, many people do not know they have it until lab work is performed.

Common Risk Factors for Prediabetes

Prediabetes and type 2 diabetes share many of the same risk factors.

Common risk factors may include:

• Being overweight
• Low physical activity
• Eating a diet high in processed foods
• Drinking sugar-sweetened beverages often
• High blood pressure
• High triglycerides
• Low HDL cholesterol
• Family history of type 2 diabetes
• History of gestational diabetes
• Poor sleep
• Chronic stress

Many of these risk factors can be improved with a personalized wellness plan.

How Chronic Stress May Affect Blood Sugar

Stress is not just emotional. It creates a physical response in the body.

When you experience stress, your body releases hormones such as cortisol and adrenaline. These hormones help prepare the body to respond to immediate challenges. One way they do this is by increasing glucose availability in the bloodstream.

During short-term stress, this response can be helpful. The body releases extra energy, then returns to balance once the stress passes.

However, when stress becomes chronic and continues for weeks, months, or years, elevated stress hormones may contribute to ongoing blood sugar challenges.

Cortisol, Glucose, and Prediabetes

Cortisol plays a role in blood sugar regulation. When cortisol remains elevated, the body may release more glucose into the bloodstream. Over time, this may make it harder to maintain healthy blood sugar levels, especially in people already at risk for insulin resistance.

Chronic stress may also indirectly affect blood sugar by influencing:

• Sleep quality
• Appetite
• Food cravings
• Physical activity
• Caffeine intake
• Alcohol intake
• Motivation
• Weight management
• Inflammatory response

This is why stress management can be an important part of a blood sugar support plan.

Lifestyle Changes That Support Healthy Blood Sugar

Research consistently shows that lifestyle changes can help delay or reduce the risk of type 2 diabetes in people with prediabetes.

Helpful habits may include:

• Eating balanced meals with protein, fiber, and healthy fats
• Reducing sugar-sweetened beverages
• Limiting highly processed foods
• Increasing daily movement
• Strength training when appropriate
• Prioritizing quality sleep
• Managing stress
• Supporting a healthy weight
• Monitoring blood pressure and cholesterol
• Following provider-recommended lab testing

Small steps can make a meaningful difference over time.

Stress Management for Blood Sugar Support

If chronic stress is part of your daily life, stress reduction may be one more tool to support metabolic wellness.

Helpful strategies may include:

• Deep breathing
• Walking
• Prayer or meditation
• Journaling
• Gentle stretching
• Yoga
• Spending time outdoors
• Getting enough sleep
• Talking with a counselor or therapist
• Taking breaks from screens and work demands

The goal is not to eliminate all stress. The goal is to help your body recover more effectively.

Adaptogens and Stress Support

Some patients ask about adaptogenic herbs for stress support. Adaptogens are plant-based compounds often used to support the body’s response to stress.

Common adaptogens may include:

• Ashwagandha
• Rhodiola
• Eleuthero
• Schisandra
• Holy basil

Adaptogens are not appropriate for everyone and may interact with medications or medical conditions. If you have prediabetes, diabetes, thyroid concerns, autoimmune conditions, blood pressure concerns, or take prescription medications, speak with a healthcare provider before starting any supplement.

When to Talk to a Healthcare Provider

If you have been told you have prediabetes, it is important to take it seriously. A healthcare provider can help you understand your lab results, risk factors, and next steps.

Ask your provider about:

• A1C testing
• Fasting glucose
• Insulin resistance
• Blood pressure
• Cholesterol and triglycerides
• Weight management support
• Nutrition guidance
• Stress and sleep support
• Medication options, if appropriate

Prediabetes is not a life sentence. It is a signal to take action.
