Adrenal Insufficiency

Adrenal insufficiency is a condition in which the adrenal glands don't produce enough of certain hormones, particularly cortisol and sometimes aldosterone. This is different from the unproven concept of "adrenal fatigue" - adrenal insufficiency is a medically recognized, diagnosable condition. The adrenal glands sit on top of each kidney and produce hormones essential for life. Cortisol helps the body respond to stress, maintain blood pressure, regulate metabolism, and reduce inflammation. Without adequate cortisol, the body cannot respond properly to stress, leading to potentially life-threatening situations. There are two types: primary (Addison's disease) where the adrenal glands themselves are damaged, and secondary where the pituitary gland doesn't signal the adrenals properly.

Adrenal insufficiency has different causes depending on type: Primary (Addison's Disease): - Autoimmune destruction of adrenal glands (80% of cases) - Infections (tuberculosis, HIV, fungal) - Cancer that has spread to adrenals - Bleeding into adrenals - Genetic disorders Secondary: - Long-term corticosteroid use (most common) - Pituitary tumors or surgery - Traumatic brain injury - Radiation to the brain - Infections affecting the pituitary When cortisol production stops suddenly (adrenal crisis), it can be life-threatening and requires emergency treatment.
