Growth hormone deficiency (GHD), also known as low growth hormone, is a condition where the body doesn't produce enough growth hormone (GH). This hormone, produced by the pituitary gland, is crucial for growth and development, especially during childhood and adolescence. It also plays a role in adults, influencing body composition, metabolism, and overall well-being.
Several factors can lead to low growth hormone. Sometimes, it's due to a genetic defect affecting the pituitary gland. Other times, it can result from brain injury, surgery near the pituitary gland, or certain infections. In some cases, the underlying cause remains unknown.
Key causes include:
The symptoms of low growth hormone vary depending on age. In children, the most obvious sign is significantly shorter height than their peers. They might also exhibit delayed puberty and have an underdeveloped appearance.
In adults, the symptoms are often subtler and may include:
Low growth hormone should not be ignored. If you are concerned about yourself or a child, consult a doctor.
Diagnosing GHD involves blood tests to measure GH levels. These tests are often conducted after a stimulation test, which involves administering specific substances to trigger GH release. Imaging tests, like MRI scans, may also be used to rule out other underlying conditions and assess the pituitary gland's structure.
Treatment typically involves growth hormone replacement therapy (GHRT). This involves administering synthetic growth hormone through injections. The treatment plan depends on the patient’s age and overall health. Injections are usually manageable, and the benefits often outweigh any inconvenience.
Low growth hormone impacts various aspects of health, and early detection and appropriate treatment can significantly improve quality of life. If you suspect you might have GHD, talk to your doctor. Early intervention is key. Consider contacting The Balance Clinic for more information.
