Growth Hormone

What is Human Growth Hormone (HGH)?

Human growth hormone (HGH) is a protein hormone secreted by the anterior pituitary gland. It stimulates growth, cell reproduction and cell regeneration in humans. It is also very important for several complex physiologic processes, such as metabolism.

The hypothalamus of the brain produces GHRH (growth hormone releasing hormone), which stimulates the pituitary gland to produce human growth hormone (HGH). HGH is converted into IGF-1 (insulin-like growth factor-1) in the liver, which has many important functions. The anterior pituitary gland releases growth hormone in spurts every 3 to 5 hours throughout the day. Growth hormone levels are often the highest about an hour after the onset of sleep, and 50% of daily growth hormone production is produced during deep sleep (stages 3 and 4 of NREM).

Growth hormone levels can be affected by many factors, including:

Human Growth Hormone-data

Increases Human Growth Hormone Decreases Human Growth Hormone
  • Deep sleep
  • Exercise
  • Nicotinic acid (Niacin)
  • Fasting
  • Increase in sex hormones such as testosterone
  • replacement in men or women and estrogen
  • replacement in women
  • GHRH (i.e., ghrelin, sermorelin)
  • Stimulators of GHRH (i.e., clonidine and L-DOPA)
  • Inhibitors of Somatostain (i.e., hypoglycemia, arginine and propranolol)
  • Dihydrotestosterone (DHT)
  • Medications (i.e. glucocorticoids)
  • High blood sugar (hyperglycemia)
  • Somatostatin (a.k.a. growth hormone inhibitinghormone GHIH), a hormone produced in the brain
    that inhibits growth hormone production by the
    pituitary when serum HGH (or IGF-1) levels are too high

Functions of Growth Hormone in the Body

Growth hormone is considered an anabolic hormone because it stimulates the

build-up of tissues and cells. Growth hormone has many important functions in the
body, including:

  • Promotes bone growth and strength
  • Increases muscle mass and strength
  • Promotes fat breakdown (lipolysis)
  • Increases protein synthesis
  • Stimulates all organs to grow (except the brain)
  • Increases height in children and adolescents
  • Plays a role in homeostasis (balance in the human body)
  • Stimulates the immune system
Growth Hormone Deficiency

Adult-onset growth hormone deficiency is diagnosed in adults who have symptoms of low growth hormone as well as a medical condition causing low growth hormone levels. Medical conditions causing low growth hormone levels are often conditions that cause damage of the pituitary gland (from a tumor, radiation, surgery, trauma, or loss of blood supply). Growth hormone deficiency in adults due to pituitary disease is rare, occurring in 10 out of every 1 million people.

Like the other hormones in the human body, human growth hormone significantly declines with aging. The symptoms that people often attribute to aging are actually due to low hormone levels caused by age-related hormone decline. Human growth hormone (HGH) is a perfect example of this. Human growth hormone is measured by the amount of insulin growth factor (IGF-1) in the blood. On average, IGF-1 levels decline from 260 ng/ml at age 20 to 120 ng/ml at age 45. That’s more than a 50% decline! The decline then continues to an IGF-1 level of 50 or less by age 85.

Symptoms of low growth hormone levels include:

  • Fatigue and low energy levels
  • Increased body fat, especially around the waist
  • Decreased muscle mass and strength
  • Worsening concentration and memory
  • Baldness in men
  • Reduced bone mass and osteoporosis
  • Increased LDL (bad) cholesterol
  • Cardiovascular disease

Your Solution: HGH Treatments for Low Growth Hormone Levels

There are many treatment options for low growth hormone levels. Balancing other hormone deficiencies often significantly improves growth hormone levels. Lifestyle changes such as sleeping better, regular exercise, and healthy eating can improve growth hormone levels. There are also some pharmaceutical-grade supplements that will stimulate growth hormone levels. Your physician may recommend medications for growth hormone if you are symptomatic and your growth hormone levels remain low despite balancing of the other hormones and incorporation of healthy lifestyle changes.

Hormone balance with natural bioidentical hormone replacement therapy significantly improves the patient’s quality of life and health while preventing chronic disease and illness. Balancing growth hormone levels will have the following benefits:

  • Improves energy levels
  • Increases fat loss, especially abdominal fat
  • Increases muscle tone, muscle mass, and strength
  • Improves mood and general sense of well being
  • Improves memory and concentration
  • Improves skin thickness and reduces wrinkles
  • Decreases the risk of heart disease and osteoporosis (weak bones)
