What is Steroid?

Steroids are hormones produced by the body itself, these are a derivation of a primary molecule. It is a hydrocarbon from which other substances are also derived. Steroids are hormones secreted by body glands and dispersed through the bloodstream.


They are produced by:

        The pituitary gland
        Parathyroid glands
        Thyroid gland
        Pancreas
        Kidney glands
        The thymus
        The gonads
        Sex glands

And there are divisions in types:

        Corticoids
        Glcocorticoids
        Mineral-corticoids

Androgens:

        Androsterone
        Testosterone and
        Androstendione

Female sex hormones:
        Estrogens
        Prolactin Follicle-stimulating hormone and
        Luteinizing agent, progesterone, oxytocin.

Both androgen and female hormones are synthesized, anabolic steroids or simple steroids used to increase muscle mass.

Other types of steroids are vitamin D, and its derivatives, since they are pre-hormones.

Steroids are synthesized by cholesterol within the human body but are also synthesized artificially in specialized laboratories.


  What are steroids for?


Steroids have several functions within the human body. Among those that emphasize the regulation of different functions of the organism as the metabolism of carbohydrates, proteins and lipids. It regulates the balance of electrolytes and homeostasis (metabolism), which regulates the functions that exist within the body and water levels in the cells of the body.

It also regulates the levels of the cardiovascular, renal, skeletal muscle and nervous system.

  Regulatory Function:

Some regulate salt levels and secretion of bile, as well as the amount of water in the cells, and in general in the body, generating a state of homeostasis.

  Structural function:

Cholesterol is a steroid that is part of the structure of the membranes of cells. From the cholesterol are synthesized the other steroids, in the human body.

Hormonal Function:

Steroid hormones are: corticosteroids, male hormones (androgens), female sex hormones, vitamin D, and others.

What are steroids for?

In medicine they are used in the treatment of conditions that occur when the body produces a low amount of testosterone, such as delayed puberty and some kinds of sexual impotence.

They are also prescribed as treatment for patients with AIDS and degenerative diseases that cause loss of muscle mass.

And in cases such as lack of vitamin D (which is a steroid), in autoimmune diseases such as multiple sclerosis, rheumatoid arthritis, Crohn's disease, lupus, type 1 diabetes, chronic lymphocytic leukemia, certain types of cancer And even dementia.

The most abundant androgen in men is testosterone, primarily produced in the testes. Testosterone, as well as estrogen, is a powerful regulator of metabolism, testosterone is a beneficial hormone, as it increases muscle recovery and strength, as well as the body's metabolism to increase its muscle mass, regulates the amount of fat of the body.

Steroids also cause damage and disorders such as:

        Liver tumors
        Cancer
        Jaundice
        Edemas (fluid retention)
        Arterial hypertension
        Elevation of bad cholesterol
        Decreased good cholesterol.
        Renal tumors
        Acne
        Muscle spasms (in bodybuilders)
        Muscle hypertrophy
        Testicular hypertrophy
