Human Growth Hormone (HGH), or somatotropin, is a peptide hormone produced by the anterior pituitary gland. It plays a crucial role in growth, body composition, cell repair, and metabolism. HGH stimulates the liver to produce an insulin-like growth factor known as IGF-1, which is responsible for the growth-promoting effects of HGH on almost every tissue in the body.

The body naturally produces HGH, or human growth hormone, in the pituitary gland, which is responsible for cell development and regeneration. Better bone density and muscle mass are impossible without the growth hormone, and it plays a crucial part in maintaining human tissue, including that of the brain and other organs. When produced, this growth hormone remains all active in the bloodstream for a few minutes only, and this is somewhat enough for the liver to convert it into growth factors, the most important of which is IGF-1, or insulin-like growth factor 1, which is featured with several anabolic traits.

This article aims to provide an in-depth overview of HGH, including its physiological functions and therapeutic applications.

what is HGH

What is it, and how does it work?

Often called HGH, this hormone is produced by the pituitary gland, which is the pea-shaped structure at the base of one’s brain that helps properly grow muscles, bones, and other organs. Specifically, the somatotropic cells within the anterior lobe are responsible for synthesizing and secreting HGH into the bloodstream. The GH is also necessary for kids to grow properly, so if a child’s body is not able to make enough of the hormone, he or she might remain short. The amount of human growth hormones generally decreases in middle age and almost stops when one reaches the adult phase of life.

HGH in the Human Body

Human Growth Hormone (HGH) is a driver of physical growth and a key player in maintaining physiological homeostasis throughout adulthood. One of the most crucial arenas in which HGH exerts its influence is metabolism, the complex network of biochemical processes that govern energy utilization, storage, and expenditure within the body.

Functions:

HGH exerts its effects through both direct and indirect actions. It directly binds to specific receptors on target cells, initiating intracellular signaling cascades that modulate gene expression and protein synthesis. Indirectly, HGH stimulates the production of insulin-like growth factor 1 (IGF-1), a hormone that mediates many of HGH’s anabolic effects.

The key functions of HGH include:

    Growth and Development: HGH is essential for linear growth, promoting bone elongation and cartilage growth. It also stimulates muscle growth and development, contributing to overall body composition.

    Cell Regeneration and Repair: HGH promotes tissue repair and regeneration by stimulating cell proliferation, differentiation, and protein synthesis. This action is crucial for maintaining the integrity of various organs and tissues throughout the body.

HGH and Metabolism

HGH is pivotal in regulating carbohydrate, lipid, and protein metabolism. It influences glucose and fat utilization, promotes protein synthesis, and modulates energy expenditure.

HGH and Carbohydrate Metabolism: HGH exhibits a diabetogenic effect, meaning it opposes the action of insulin, the hormone responsible for regulating blood glucose levels. HGH increases blood glucose concentrations by decreasing glucose uptake in peripheral tissues and stimulating glucose production in the liver (gluconeogenesis). This counter-regulatory effect on insulin is essential for maintaining glucose availability during fasting or increased energy demands.

HGH and Lipid Metabolism: HGH plays a pivotal role in lipid metabolism by stimulating lipolysis, which is the breakdown of stored triglycerides in adipose tissue. This process releases free fatty acids into the bloodstream, providing an alternative energy source for tissues, especially during fasting or exercise. Additionally, HGH promotes fat oxidation and the utilization of fatty acids for energy production, contributing to overall metabolic efficiency.

HGH and Protein Metabolism: HGH exerts anabolic effects on protein metabolism, stimulating protein synthesis and reducing protein breakdown. This action is particularly evident in skeletal muscle, where HGH promotes muscle growth and repair. However, HGH’s impact on protein metabolism extends beyond muscle tissue, influencing protein turnover in various organs and tissues throughout the body.

HGH and Energy Expenditure: Research suggests that HGH may also influence energy expenditure, the total amount of energy the body uses over a given period. Studies have shown that HGH administration can increase resting energy expenditure, potentially contributing to weight loss and improved body composition.

HGH Deficiency

Growth Hormone Deficiency (GHD) is a medical condition characterized by the pituitary gland’s inadequate production or secretion of human growth hormone (HGH). This deficiency can significantly impact growth, development, and metabolic function, leading to various clinical manifestations across different age groups.

Causes

  • Genetic Factors: Certain genetic mutations can impair the production or release of HGH. Conditions like Turner syndrome and Prader-Willi syndrome are associated with HGH deficiency.
  • Pituitary Disorders: Damage to the pituitary gland due to tumors, surgery, radiation therapy, or traumatic brain injury can reduce HGH production.
  • Hypothalamic Dysfunction: The hypothalamus controls the pituitary gland. Dysfunction in this part of the brain due to congenital conditions, tumors, or trauma can lead to HGH deficiency.
  • Chronic Diseases: Chronic kidney disease and autoimmune disorders can interfere with HGH production.
  • Idiopathic Causes: In many cases, the cause of HGH deficiency is unknown (idiopathic).
  • Age-induced HGH deficiency: As we age, HGH production has a natural decline.

Side Effects of HGH Deficiency

  • In Children:
    • Growth Failure: Significantly shorter stature than peers.
    • Delayed Puberty: Late onset of puberty or absence of puberty.
    • Increased Fat: Higher fat mass, particularly around the abdomen.
    • Poor Bone Density: Increased risk of fractures and delayed bone maturation.
  • In Adults:
    • Reduced Muscle Mass and Strength: Loss of muscle mass and decreased strength.
    • Increased Fat Mass: Accumulation of fat, especially around the waist.
    • Bone Density Reduction: Higher risk of osteoporosis and fractures.
    • Cardiovascular Issues: Higher risk of cardiovascular diseases due to altered lipid metabolism.
    • Decreased Energy Levels: Fatigue and reduced physical endurance.
    • Psychological Effects: Depression, anxiety, and impaired quality of life.

Symptoms

  • In Children:
    • Slow Growth Rate: Noticeably slower growth compared to peers.
    • Short Stature: Height significantly below the average for age and gender.
    • Delayed Development: Delayed tooth development and slower maturation of bones.
    • Chubbiness: A tendency to be chubby, particularly around the abdomen.
  • In Adults:
    • Decreased Muscle Strength and Mass: Noticeable loss of muscle and strength.
    • Increased Abdominal Fat: Higher levels of fat around the midsection.
    • Reduced Bone Density: Higher susceptibility to fractures and osteoporosis.
    • Fatigue and Weakness: Persistent tiredness and lack of energy.
    • Depressed Mood: Symptoms of depression and anxiety.
    • Poor Quality of Life: Reduced overall well-being and life satisfaction.

Diagnosis

  • Medical History and Physical Examination: Initial assessment includes a detailed medical history and physical examination to identify symptoms and potential causes.
  • Growth Charts: In children, growth charts are used to track growth patterns and compare them with standard growth percentiles.
  • Blood Tests: Measuring levels of HGH and other related hormones, such as insulin-like growth factor 1 (IGF-1), which reflects the amount of HGH in the body.
  • Stimulation Tests: Tests that stimulate the release of HGH to see if the pituitary gland responds appropriately. These tests include insulin tolerance, arginine, and glucagon stimulation tests.
  • Imaging Studies: MRI or CT scans of the brain to examine the pituitary gland and hypothalamus for abnormalities such as tumors or structural issues.
  • Bone Age Assessment: X-rays of the hand and wrist determine bone age, indicating delayed growth in children.

Understanding the causes, symptoms, and diagnostic methods for HGH deficiency is crucial for early identification and effective management.

HGH Therapy to Overcome Deficiency

HGH therapy involves the administration of synthetic or recombinant human growth hormone (HGH) for managing various medical conditions resulting from HGH deficiency.

The use of injectible HGH is approved for only clinically proven conditions that include:

  1. Growth Hormone Deficiency (GHD): The most well-established use of HGH therapy is in treating GHD, a condition characterized by insufficient production of HGH by the pituitary gland. GHD can occur in children or adults, leading to growth failure, metabolic abnormalities, and reduced quality of life. HGH therapy aims to restore normal HGH levels, promote growth, improve body composition, and enhance overall well-being.
  2. Other Approved Uses: In addition to GHD, HGH therapy is approved for several other medical conditions, including:
    • Turner Syndrome: A genetic disorder affecting females, characterized by short stature and ovarian insufficiency. HGH therapy can improve growth and development in girls with Turner syndrome.
    • Chronic Kidney Disease: HGH therapy may be used to treat growth failure and muscle wasting associated with chronic kidney disease in children.
    • HIV/AIDS-Related Wasting: HGH therapy can help to increase muscle mass and improve body composition in individuals with HIV/AIDS-related wasting syndrome.
    • Short Bowel Syndrome: HGH therapy may improve nutrient absorption and promote growth in children with short bowel syndrome.

HGH therapy is typically administered through subcutaneous injections, with the dosage and frequency varying depending on the individual’s age, weight, and specific medical condition.
