What Is HGH and How Does It Work in the Human Body?
Human Growth Hormone (HGH) plays one of the most important roles in human development, metabolism, tissue repair, and overall vitality. While most people associate HGH with childhood growth, adults rely on it just as much—just in different ways. Understanding what HGH is and how HGH works in the human body can help you recognize when hormone levels may be out of balance and whether you may benefit from specialized treatment such as HGH therapy for adults.
At Wellspring Medical, patients receive individualized hormone evaluations, HGH and IGF-1 testing, and physician-guided therapy programs designed to restore optimal health.
What Is HGH?
Human Growth Hormone (HGH), also known as somatotropin, is a peptide hormone produced naturally by the pituitary gland. It supports key functions such as:
- Cell growth and regeneration
- Metabolism of fats, proteins, and carbohydrates
- Immune system support
- Muscle development and recovery
- Healthy bone density
- Maintaining energy and cognitive performance
When you ask, "What is HGH?", the simplest explanation is that HGH helps the body repair, rebuild, and maintain itself. Without adequate levels, the body begins to age more rapidly and loses its ability to restore tissue efficiently.
How Does HGH Work in the Human Body?
To understand how HGH works, it helps to look at the chain of events it triggers:
-
HGH is released by the pituitary gland
The pituitary releases HGH in pulses, mostly during deep sleep. This is why poor sleep or high stress can significantly reduce natural hormone production. -
HGH travels through the bloodstream
Once released, it moves throughout the body, interacting with various tissues. However, HGH itself does not perform every action directly. -
HGH stimulates the liver to produce IGF-1
One of the most important functions of HGH is signaling the liver to produce Insulin-Like Growth Factor 1 (IGF-1). IGF-1 is responsible for most of the growth and repair processes associated with HGH.
(For more details, Wellspring Medical provides HGH Levels and IGF-1 Testing to measure these markers accurately.) -
IGF-1 drives cell regeneration, healing, and metabolism
This is the stage where patients feel the real benefits:
- Faster metabolic rate
- Better muscle tone
- Enhanced fat-burning
- Increased energy
- Improved skin elasticity
- Faster recovery from exercise
This is why low IGF-1 levels often indicate a deficiency even if HGH is still being produced in small amounts.

Signs of Low HGH in Adults
Adults do not stop needing HGH—production simply decreases with age. For some individuals, the decline is so severe that it leads to Adult Growth Hormone Deficiency (AGHD).
Common symptoms include:
- Low energy or chronic fatigue
- Increased belly fat
- Slower metabolism
- Loss of muscle mass
- Thinning or dry skin
- Reduced exercise performance
- Brain fog or low concentration
- Poor sleep
- Reduced sexual wellness
If several of these symptoms sound familiar, hormone testing may be beneficial.

FAQs
HGH (Human Growth Hormone) is a natural hormone produced by the pituitary gland. It supports metabolism, tissue repair, muscle development, energy levels, and overall wellness. Adults continue to need HGH for healthy body function, even after growth is complete.
HGH is released in pulses during deep sleep, travels through the bloodstream, and signals the liver to produce IGF-1. Together, HGH and IGF-1 regulate cell growth, fat metabolism, muscle repair, and energy levels.
Common symptoms include fatigue, increased belly fat, poor sleep, reduced muscle mass, slower metabolism, decreased libido, and difficulty concentrating. Blood testing is required for an accurate diagnosis.
HGH and IGF-1 levels are measured through lab blood testing. Wellspring Medical provides comprehensive hormone panel evaluations and physician-guided interpretation.
Patients may experience improved energy, increased lean muscle, fat reduction, enhanced sleep, better skin quality, stronger bone density, improved mood, and overall rejuvenation—when treatment is prescribed and monitored by medical professionals.
Yes—when administered under a licensed physician's supervision. Wellspring Medical ensures patients receive personalized dosing, ongoing monitoring, and FDA-approved medications.
Most patients start noticing improvements within 4–8 weeks, with continued benefits over several months of consistent therapy.
HGH supports fat metabolism and increases lean muscle mass, which helps improve body composition. It is not a standalone "weight-loss drug," but works effectively as part of a complete hormone optimization plan.
