Why Deficiency In
Human Growth Hormones
Can Make You Depressed
One of the depression causes that is less commonly known is deficiency in the human growth hormone (HGH) hormone.
Importance of HGH
HGH is produced by the pituitary gland and it helps children grow, while it helps adults maintain optimal health and youthful vigor .
Unfortunately, levels of this hormone decline as we age. This decline starts when we are in our 20s to 30s, and levels become half when we reach age 60, and it is estimated that about 50% of those at 65 years old are partially or wholly deficient in this hormone .
According to Thierry Hertoghe, M.D., an expert on hormone deficiency, over-anxiety or hyper-emotionality is a sign of growth hormone deficiency. This is because the growth hormone has a calming effect and helps us to deal with stresses. 
It is also found that adults with deficiency in HGH tend to have decreased energy and quality of life .
Research on HGH deficiency and depression
In turn, researchers at St. Thomas Hospital in London and Benzt-Ak Bengtsson, M.D., at Sahlgrenska Hospital in Sweden found that HGH had the ability to reverse chronic fatigue and depression. It is believed that HGH crosses the blood-brain barrier to raise endorphin levels, so as to improve mood and energy levels. It possibly also lowers dopamine, too much of which leads to agitation. 
Besides the ability to improve depression and fatigue, HGH also plays an important role in our immunity [2, 3]. HGH boosts our thymus gland (which produces all the immunity factors we need) and reverses the thymus shrinkage that occurs with age . This means that HGH can protect us from diseases, including systemic infections like candidiasis, which has been found to contribute to depression.
HGH also has the ability to reverse the shrinking and functional decline of organs (e.g. heart, liver and kidneys) due to aging [2, 3]. Studies at the University of California at Berkeley found that HGH was also able to reverse shrinking of the brain in aging rats, possibly by stimulating neurons to regrow dendritic connections, and the glial cells (which nourish the neurons) to regenerate .
In turn, this ability could mean that HGH could offer protection for those with depression against depression related brain injury.
Using HGH to deal with depression
Given the efficacy of HGH in addressing HGH-linked depression causes, this may be a worthy path for you to pursue.
However, first, you have to ascertain if HGH deficiency is indeed one of your depression causes.
To do so, you should first assess your current levels of HGH by measuring your body’s level of somatomedin C (IGF-I or Insulin-Growth-Factor I; a growth hormone marker) via a blood test. The ideal would be to have the IGF-I level of a normal 30 to 40 year old person (i.e. high 200s or low 300s). 
Subsequently, when it comes to fighting HGH-linked depression causes, there are three possible natural methods of increasing HGH levels in your body in order to deal with your depression. Read more about them.
Other hormonal imbalances linked to depression
Besides deficiency in the Human Growth Hormone, other hormonal imbalances that can bring about depression include:
- DHEA deficiency
- Thyroid hormone deficiency
- Melatonin imbalances
- Pregnenolone deficiency
- Sex hormone imbalance
