The Science Behind Your Symptoms: The Digestive System

Why can adrenal insufficiency affect your digestion from the very beginning of the digestive process to the very end?

In this episode, we explore the important relationship between adrenal insufficiency and the digestive system. Many people experience symptoms such as nausea, loss of appetite, abdominal pain, bloating, constipation, diarrhea, reflux, or feeling full after only a few bites—but few realize how closely these symptoms can be tied to cortisol and the body’s stress response.

We break down how cortisol helps support digestion by maintaining blood flow to the gastrointestinal tract, regulating inflammation, influencing gut motility, supporting nutrient absorption, and helping the body respond to the physical stress of eating and illness. When cortisol is insufficient or unable to rise appropriately during times of increased demand, digestion can become slower, less efficient, and far less predictable.

This episode also explores why stress, illness, dehydration, medication timing, and other hormone imbalances can worsen gastrointestinal symptoms, and why people with primary, secondary, tertiary, and steroid-induced adrenal insufficiency may experience digestive problems differently. We discuss why digestive symptoms are often misunderstood and why they can sometimes be mistaken for unrelated gastrointestinal disorders.

Most importantly, we focus on understanding the physiology behind these symptoms. Digestive issues with adrenal insufficiency are not simply “stomach problems”—they may reflect the body’s broader struggle to maintain balance when cortisol support is limited.

If you’ve ever wondered why your digestive system seems to stop working when you’re under stress, become ill, or experience an adrenal crash, this episode will help explain the science behind those experiences.
