The Cardiovascular System in Adrenal Insufficiency: Understanding Circulation, Orthostatic Instability, Stress Physiology, and Early Warning Patterns

Living with adrenal insufficiency can feel unpredictable.

One day your blood pressure drops when you stand. Another day it rises without explanation. Your heart races. You feel weak, lightheaded, overheated, or suddenly exhausted — and routine tests may look normal.

Adrenal insufficiency is not just a hormone disorder.
It is a disorder of regulation.

In The Cardiovascular System in Adrenal Insufficiency, Rick Disler explores how cortisol and aldosterone shape circulation, orthostatic stability, sympathetic activation, and stress physiology. This focused guide helps readers understand why symptoms fluctuate — and how to recognize meaningful patterns without fear.

Whether you live with:

• Primary adrenal insufficiency (Addison’s disease)
• Secondary adrenal insufficiency
• Tertiary adrenal insufficiency
• Steroid-induced adrenal insufficiency

this book explains the cardiovascular impact in clear, structured language.

Inside, you’ll learn:

• Why blood pressure may fall — or rise
• Why some patients experience hypertension
• How aldosterone differences affect primary vs secondary adrenal insufficiency
• What orthostatic hypotension and POTS overlap can look like
• How stress, illness, dehydration, and heat influence stability
• Early cardiovascular warning signs before adrenal crisis
• When to monitor, when to call your clinician, and when to seek urgent care

Grounded in established endocrine guidelines and peer-reviewed physiology, this book bridges the gap between what patients experience and what clinicians are trained to measure.

It is written for patients, caregivers, and clinicians alike.

Clear understanding reduces uncertainty.
Structured knowledge improves safety.
Recognizing regulation changes everything.

Part of the My Adrenal Life Mini Series, this volume offers calm, evidence-based insight into one of the most misunderstood aspects of adrenal insufficiency.
