Growth hormone plays an essential role in the regulation of growth, metabolism, and bone development. Abnormal levels can lead to conditions such as gigantism or dwarfism. Managing levels of this hormone is crucial for proper growth and overall good health.
Growth hormone (GH), also called somatotropin, is a hormone produced by the pituitary, a small gland located at the base of the brain.
GH plays a key role in regulating growth, especially during childhood and adolescence. It influences the body's ability to build muscle, break down fat, and maintain a healthy metabolism.
It also controls protein production and supports bone development.
Growth hormone is often measured to assess growth-related problems in children or metabolic disorders in adults. Abnormal levels may indicate pituitary disorders or other health conditions that affect growth and metabolism.
A growth hormone test is prescribed when there is a suspicion of abnormal production of this hormone in the body, often indicated by symptoms related to growth, metabolism, or bone health.
Common cases where testing may be recommended include:
To measure growth hormone levels, a venous blood test is usually done. As GH levels fluctuate throughout the day, special test methods can be used to get accurate results.
Besides fasting, it may be advisable to avoid certain medications or stressful activities before the test, as these can influence hormonal levels.
Normal levels of growth hormone vary by age and gender:
Kids
Adults
Note: Normal measurement units and ranges may vary depending on the laboratory and the methods used.
High GH levels may indicate hyperactivity in the pituitary gland.
