Disordered growth hormone secretion in fibromyalgia: a review of recent findings and a hypothesized etiology
1Dept. Medicine (L329A), Oregon Health Sciences University, Portland 97201, USA.
Abstract:
Growth hormone (GH) deficiency occurs in about 30% of fibromyalgia patients. Treatment of GH deficient fibromyalgia patients with recombinant growth hormone improves several clinical features, including the tender point count. Defective GH secretion in these patients appears to be due to increased somatostatin tone in the hypothalamus. An hypothesis is presented which relates dysfunctional GH secretion to the effects of intermittent hypercortisolemia on upregulating the density of beta-adrenergic receptors in the hypothalamus. The resulting augmentation of beta-adrenergic tone stimulates the release of somatostatin, thus, impairing GH secretion.

Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss.
