Growth hormone and liver function are connected through a complex relationship involving hormone production, metabolic regulation and cellular signalling. The liver is a major target of growth hormone (GH), but it is also responsible for producing most of the insulin-like […]
Growth hormone and kidney function are closely connected through the regulation of renal blood flow, filtration and electrolyte balance. Although growth hormone (GH) is primarily associated with growth and metabolism, the kidneys are important targets of GH and insulin-like growth […]
Growth hormone and cardiovascular health are connected through several endocrine pathways that influence cardiac muscle, blood vessels and metabolic regulation. Growth hormone (GH) and insulin-like growth factor 1 (IGF-1) contribute to normal cardiovascular physiology, but their effects depend on hormone […]
Growth hormone and immune function are connected through interactions between the endocrine and immune systems. Although growth hormone (GH) is best known for its involvement in growth and metabolism, researchers have also examined its effects on lymphocyte development, thymic tissue […]
Growth hormone and bone metabolism are connected through the regulation of skeletal growth, bone formation and tissue remodelling. Growth hormone (GH) and insulin-like growth factor 1 (IGF-1) influence bone cells throughout life, from childhood growth plate activity to the maintenance […]
Growth hormone receptor mutations provide some of the clearest evidence that producing growth hormone (GH) and responding to it are separate biological processes. The growth hormone receptor (GHR) allows cells to recognise GH and activate intracellular pathways involved in growth, […]
Growth hormone sex differences are an important feature of human endocrine physiology. Although growth hormone (GH) performs similar fundamental functions in males and females, its secretion patterns, hormonal regulation and downstream effects are not identical. Studies of the GH–IGF-1 axis […]
Growth hormone and ageing are closely linked through changes in the hypothalamic–pituitary endocrine system. Human studies consistently show that growth hormone (GH) secretion declines with advancing adulthood, accompanied by changes in circulating insulin-like growth factor 1 (IGF-1). However, declining GH […]
Growth hormone and fasting have a distinctive relationship. During food deprivation, pituitary growth hormone (GH) secretion often increases, even though circulating insulin-like growth factor 1 (IGF-1) may remain unchanged or decline. This apparent contradiction reflects nutritional regulation of the GH–IGF-1 […]
Growth hormone and exercise are closely connected through the body’s endocrine response to physical activity. Both resistance and endurance exercise can temporarily increase circulating growth hormone (GH), although the magnitude varies with intensity, duration and individual physiology. Importantly, a larger […]
