Growth Hormone Excess

Meaning

Growth Hormone Excess describes an endocrine condition characterized by abnormally elevated levels of growth hormone, typically from the pituitary gland. This disorder leads to distinct clinical syndromes: gigantism in children and adolescents before epiphyseal fusion, and acromegaly in adults.

Context

Growth hormone (GH) secretion is regulated by hypothalamic hormones and IGF-1 feedback. The pituitary gland produces GH. A somatotroph adenoma in the anterior pituitary autonomously secretes excessive GH, disrupting hormonal balance.

Significance

Identifying growth hormone excess is clinically important due to its progressive and debilitating systemic effects. Early diagnosis and intervention mitigate long-term complications, including physical changes, cardiovascular dysfunction, metabolic disturbances like diabetes, and increased mortality. Recognizing characteristic symptoms guides timely evaluation.

Mechanism

The core mechanism involves overproduction of growth hormone by a pituitary tumor, usually a benign somatotroph adenoma. Excess GH stimulates the liver and other tissues to produce increased insulin-like growth factor 1 (IGF-1). IGF-1 mediates GH’s anabolic and growth-promoting effects, leading to proliferation of bone, cartilage, and soft tissues, causing somatic overgrowth.

Application

Clinically, growth hormone excess manifests as gradually developing signs and symptoms, often making diagnosis challenging. Patients may present with subtle changes like increased shoe or ring size, headaches, or visual field defects. Comprehensive diagnostic protocols involve biochemical testing and imaging to confirm diagnosis and localize the source, guiding therapeutic decisions.

Metric

Diagnosis and monitoring of growth hormone excess rely on specific biochemical measurements. Serum IGF-1 levels serve as a reliable screening tool. A confirmatory test is the oral glucose tolerance test (OGTT), where failure of GH levels to suppress below a threshold confirms autonomous secretion. Pituitary magnetic resonance imaging (MRI) localizes the adenoma.

Risk

Uncontrolled growth hormone excess poses considerable health risks. Patients face elevated cardiovascular complications, including hypertension, cardiomyopathy, and arrhythmias, contributing to premature mortality. Metabolic disturbances, such as impaired glucose tolerance and type 2 diabetes mellitus, are common due to GH’s insulin-antagonistic effects. Other risks include arthropathy, carpal tunnel syndrome, and increased propensity for certain neoplasms.
