ICD-10: E31.1

Clinical Description of ICD-10 Code E31.1: Polyglandular Hyperfunction

Polyglandular hyperfunction refers to a condition characterized by the overactivity of multiple endocrine glands. This condition can lead to a variety of hormonal imbalances and associated symptoms, depending on which glands are involved and the hormones they produce. The ICD-10 code E31.1 specifically categorizes this condition under the broader classification of disorders of the endocrine system.

Key Features of Polyglandular Hyperfunction

1. Definition and Mechanism:
   - Polyglandular hyperfunction is defined as the simultaneous hyperactivity of two or more endocrine glands. This can result from various underlying mechanisms, including autoimmune processes, genetic predispositions, or neoplastic changes (tumors) affecting the glands.

2. Common Glands Involved:
   - The condition often involves the following glands:

   • Thyroid Gland: Overproduction of thyroid hormones (hyperthyroidism).
   • Adrenal Glands: Excess production of cortisol (Cushing's syndrome) or aldosterone (Conn's syndrome).
   • Pituitary Gland: Overproduction of hormones that stimulate other glands, such as ACTH (adrenocorticotropic hormone) or TSH (thyroid-stimulating hormone).

3. Symptoms:
   - Symptoms can vary widely based on which glands are hyperactive. Common manifestations may include:

   • Weight loss or gain
   • Increased appetite
   • Anxiety or mood changes
   • Fatigue
   • Changes in skin pigmentation
   • Hypertension (high blood pressure)
   • Hyperglycemia (high blood sugar levels)

4. Associated Conditions:
   - Polyglandular hyperfunction can be part of broader syndromes, such as:

   • Polyglandular Autoimmune Syndrome (PAS): A condition where multiple autoimmune disorders affect different endocrine glands.
   • Multiple Endocrine Neoplasia (MEN): Genetic syndromes that predispose individuals to tumors in multiple endocrine glands.

5. Diagnosis:
   - Diagnosis typically involves a combination of clinical evaluation, laboratory tests to measure hormone levels, and imaging studies to assess gland size and function. Endocrinologists often conduct these evaluations to determine the specific glands involved and the nature of their hyperfunction.

6. Management:
   - Treatment strategies depend on the specific glands affected and the severity of symptoms. Options may include:

   • Medications to control hormone levels.
   • Surgical interventions to remove hyperactive glands or tumors.
   • Hormone replacement therapy if gland removal leads to deficiencies.
