what are steroids

Steroids are man-made versions of chemicals, known as hormones, that are made naturally in the human body. They are designed to act like these hormones to reduce inflammation and are also known as corticosteroids, which are different from anabolic steroids used by bodybuilders and athletes. Steroids are used to reduce inflammation and ease symptoms such as swelling, pain, and stiffness. Inflammation is the bodys natural reaction to infection or bacteria, and steroids can be used to reduce this immune response. Steroids come in many different forms, including tablets, liquids, inhalers, nasal sprays, injections, creams, lotions, and gels. Most steroids are only available on prescription, but a few can be bought from pharmacies and shops. Steroids do not tend to cause significant side effects if theyre taken for a short time or at a low dose, but sometimes they can cause unpleasant side effects, such as an increased appetite, mood changes, and difficulty. Corticosteroids are medicines that quickly fight inflammation in the body, and they work like the hormone cortisol, which the adrenal glands make. They slow or stop the immune system processes that trigger inflammation and help treat conditions that cause irritation and swelling, such as rheumatoid arthritis, asthma, and chronic obstructive pulmonary disorder. Steroids are strong medicines, and they can have side effects, including weakened bones and cataracts, so they are usually taken for as short a time as possible.
