When we talk about hormonal imbalance in the male middle-aged and elderly, men after the age of 40 years and older, we mean the following:
The level of growth hormone, which is one of the most important hormones necessary for maintaining health in the body decreases with time. Consequently, the reduced level of metabolism. All chemical reactions are slowed down within us. Organism can not produce enough cells to replace dead and damaged, and thus the volume of the internal organs of the heart, liver, kidney, thyroid, testes - decreasing.
Begins reducing hormone DNEA (degidroandrosteron) responsible for the production of sex hormones. These hormones are also responsible for producing antibodies, which protect the body from various diseases.
A person 65 years and the number of DNEA not exceed 30% of its level at a young age. If we consider that DNEA improves brain function - memory, and short and long, strengthens bone tissue, improves immune system function - is understood its importance. Starts and reduced levels of sex hormone - testosterone. This leads to a decrease in sexual activity due to reduced sexual desire, etc.
With age, the male also reduced the number of the hormone melatonin, is responsible for our biological clock. Melatonin affects sleep quality. Amount of melatonin is again a direct impact on the selection of sex hormones.
By 65 years, and the pineal gland (pineal gland), which distinguishes melatonin - lose up to 90% of its weight. Number releasing hormone also decreases sharply - this explains the sleep disturbance in older people.
Thyroid hormones also begin to function at a lower level, compared to younger years. Thyroid hormones are responsible for the metabolic process - so reduced with increasing age.
The second major direction of change in men after 40 years - a violation of patency of blood vessels due to deposits on the walls of cholesterol plaques. Initially, this leads to a decrease in the elasticity of the vessel, in the future with an increase in the number of plaques and their size that causes poor circulation due to partial or complete blockage of blood vessels.
