Steroids, also known as corticosteroids, are a type of anti-inflammatory medicine used to treat a wide range of conditions. They are different from anabolic steroids, which are often used illegally by some people to increase their muscle mass. Steroids come in many different forms, including tablets, liquids, inhalers, nasal sprays, injections, creams, lotions, and gels. Some common uses for steroids include treating asthma, chronic obstructive pulmonary disease (COPD), hay fever, severe hives, eczema, arthritis, lupus, multiple sclerosis, and inflammatory bowel disease. Steroids work by reducing inflammation and swelling in the body, which can help ease symptoms of these conditions.

Steroids are a man-made version of hormones normally produced by the adrenal glands, which are two small glands found above the kidneys. Steroids reduce redness and swelling (inflammation) by reducing the production of chemicals that cause inflammation and by affecting the way white blood cells work. Steroids can also reduce the activity of the immune system, which can be helpful in treating conditions where the immune system is overactive and causing damage to the bodys tissues.

Its important to note that steroids can cause side effects, especially if used for a long time or in high doses. Some common side effects include weight gain, increased appetite, mood changes, difficulty sleeping, acne, and fluid retention. Steroid treatment can also stop the body from producing natural hormones, which can be dangerous if you get ill, have an accident, or need an operation. If you are prescribed steroids, your healthcare professional may give you a steroid card to carry with you, which lets other healthcare professionals and emergency workers know that you are taking steroids and has details of your medicine and dose.
