what do steroids actually do

Steroids are a type of drug that can be used for medical purposes or illegally to enhance athletic performance. Anabolic steroids are synthetic hormones that help with the growth and repair of muscle tissue and imitate the male sex hormone, testosterone. Steroids can come in many different forms, including tablets, liquids, inhalers, nasal sprays, injections, creams, lotions, and gels. Steroids work by reducing redness and swelling (inflammation) and can help with inflammatory conditions such as asthma and eczema. They can also signal muscle cells to make more protein, which can lead to increased muscle mass. Steroids can have serious side effects, including psychological effects, and can cause harm with some ill effects not likely to turn up until years later. Steroids can be prescribed by a doctor to treat hormonal problems or loss of muscle caused by diseases like cancer or HIV.
