Anabolic Steroids , what are they?
Friday, March 30th, 2007Anabolic androgenic steroids are a class of natural and synthetic steroid hormones that promote cell growth and division, resulting in growth of several types of tissues, especially muscle and bone. Different anabolic androgenic steroids have varying combinations of androgenic and anabolic properties, and are often referred to in medical texts as AAS (anabolic/androgenic steroids). Anabolism is the metabolic process that builds larger molecules from smaller ones.
Anabolic steroids were first discovered in the early 1930s and have since been used for numerous medical purposes including stimulation of bone growth, appetite, puberty, and muscle growth. The most widespread use of anabolic steroids is their use for chronic wasting conditions, such as cancer and AIDS. Anabolic steroids can produce numerous physiological effects including increases in protein synthesis, muscle mass, strength, appetite and bone growth. Anabolic steroids have also been associated with numerous side effects when administered in excessive doses and these include elevated cholesterol (increase in LDL, decreased HDL levels), acne, elevated blood pressure, hepatotoxicity, and alterations in left ventricle morphology.
Today anabolic steroids are controversial because of their widespread use in competitive sports and their associated side effects. While there are numerous health issues associated with excessive anabolic steroid use, public understanding of the true risks remains limited. Anabolic steroids are controlled in a few countries including the United States, where they are listed as Schedule III in the Controlled Substances Act, as well as Canada and Britain who also have laws controlling their use and distribution.
