Overview

Addison's disease, also known as primary adrenal insufficiency, is a long-term disorder where the body does not produce enough of certain essential hormones. It occurs when the adrenal glands are damaged and cannot produce sufficient cortisol or aldosterone.

Understand this condition

The adrenal glands are tiny organs that produce hormones necessary for almost every body function. When these glands fail, the body loses its ability to balance minerals and handle physical stress. This disruption affects energy levels, blood pressure, and how the body processes nutrients.

Why it happens

The condition usually develops when the immune system attacks the adrenal cortex, destroying hormone-producing cells. This process typically happens slowly over many years before symptoms become noticeable. Triggers like injury or illness can then push a compromised system into a crisis.

Real-world scenarios

  • This often appears as extreme fatigue that does not improve with rest.
  • People may notice their skin darkening as if they have a perpetual tan.
  • This often appears as an intense, unusual craving for salty foods.
  • People may notice dizziness or lightheadedness when standing up quickly.

Common vs serious explanations

Common
  • General physical exhaustion from overwork
  • Mild iron-deficiency anemia
  • Chronic stress or anxiety disorders
  • Nutritional deficiencies or poor diet
Serious
  • Addisonian crisis requiring immediate medical intervention
  • Severe internal bleeding or hemorrhage
  • Acute systemic infection or sepsis
  • Pituitary gland failure or tumors

Primary symptoms

No symptoms mapped yet.

Causes

  • Autoimmune response attacking the adrenal glands
  • Tuberculosis or other infections
  • Gland damage from surgery or cancer
  • Genetic disorders affecting hormone production

Risk factors

  • Having another autoimmune disease (like type 1 diabetes)
  • Family history of adrenal insufficiency
  • Chronic infections like TB or HIV
  • Recent major physical trauma or surgery

How it progresses

3 stages
  1. Stage 1 — Early
    Mild or intermittent symptoms; easily mistaken for something minor.
    Often missed
  2. Stage 2 — Progressive
    Symptoms become more frequent or severe.
  3. Stage 3 — Established
    Daily life affected; medical care strongly recommended.

How it's diagnosed

  • Blood tests for sodium and potassium levels
  • ACTH stimulation test
  • Cortisol level measurement
  • CT imaging of the adrenal glands

Treatment options

General educational information only — no dosage advice. Always follow guidance from a qualified clinician.

Medical
  • Hormone replacement therapy (Hydrocortisone)
  • Aldosterone replacement (Fludrocortisone)
  • Adjusting medication doses during illness or surgery
  • Emergency corticosteroid injections for crises
Home care
  • Wearing a medical alert bracelet
  • Carrying an emergency corticosteroid injection kit
  • Maintaining a consistent salt intake
  • Managing stress levels through lifestyle habits

Complications

  • Long-term damage if untreated
  • Reduced quality of life
  • Worsening symptoms over time
  • Recurrence of addison's disease

Prevention

  • Maintain a healthy lifestyle
  • See a clinician for routine check-ups

When to seek help

Urgent — same-day care
  • Symptoms persist beyond a few days
  • Symptoms interfere with daily activities
  • New or worsening symptoms appear
  • Concerning changes related to addison's disease
🚨 Emergency — call now
  • Severe vomiting and diarrhea
  • Fainting or loss of consciousness
  • Sharp pain in the lower back or abdomen
  • Dehydration and extreme weakness
  • Confusion or mental agitation

In any emergency, call your local emergency number or go to the nearest emergency department.
