What Are the Different Types of Steroids?
Category 1: Corticosteroids (The Anti-Inflammatories)
Corticosteroids are synthetic drugs that closely resemble cortisol, a hormone naturally produced by your adrenal glands. Their primary function in medicine is to quickly and powerfully suppress inflammation and reduce overactive immune system responses.
Common Uses for Corticosteroids:
- Asthma and COPD: (Inhalers like fluticasone/Flovent) to reduce airway inflammation.
- Autoimmune diseases: (Rheumatoid arthritis, Lupus, MS) to suppress the immune system attacking the body.
- Skin conditions: (Hydrocortisone cream) for eczema, psoriasis, or poison ivy rashes.
- Severe allergies: (Prednisone pills or injections) for severe allergic reactions.
Examples of Corticosteroids
Oral/Injected: Prednisone, Dexamethasone, Methylprednisolone (Medrol Dosepak), Cortisone.
Topical/Inhaled: Hydrocortisone, Fluticasone, Budesonide.
Side Effects: Long-term use of corticosteroids can lead to weight gain, high blood pressure, osteoporosis, elevated blood sugar (diabetes risk), and a weakened immune system.
Category 2: Anabolic-Androgenic Steroids (AAS)
Anabolic-Androgenic Steroids (commonly just called “anabolic steroids”) are synthetic variations of the male sex hormone testosterone.
- Anabolic refers to muscle-building and bone-strengthening properties.
- Androgenic refers to the development of male sexual characteristics (deep voice, facial hair).
Medical Uses for Anabolic Steroids:
While infamous for sports doping, AAS have legitimate, though narrow, medical applications:
- Testosterone Replacement Therapy (TRT): Treating men with clinically diagnosed hypogonadism (low testosterone).
- Muscle-wasting diseases: Prescribed to prevent severe weight loss in patients with HIV/AIDS or advanced cancer (e.g., Oxandrolone).
- Delayed puberty: Administered to boys to stimulate natural development.
Understanding Steroid Chemistry (Advanced)
In biochemistry, a “steroid” simply refers to any organic compound with a specific core structure: four conjoined cycloalkane rings (three six-carbon rings and one five-carbon ring). Because of this shared core structure, many naturally occurring substances in your body are technically steroids, even though they aren’t drugs.
For example, Cholesterol is a steroid. Vitamin D is a secosteroid. Estrogen and Progesterone (female sex hormones) are steroid hormones. The chemical shape is what defines the category, not necessarily the effect on the body.
Frequently Asked Questions
No. Doctors prescribe corticosteroids (like prednisone) for coughs and inflammation. They break down tissues to release energy and reduce inflammation; they do not build muscle like anabolic steroids. In fact, long-term corticosteroid use can cause muscle weakness.
Anabolic steroids (testosterone derivatives) are Schedule III controlled substances and are illegal to possess without a prescription. Many topical corticosteroids (like low-dose hydrocortisone cream) are available over-the-counter legally.
No. Cortisone is a corticosteroid used to treat pain and inflammation (often via injections into joints). It has no muscle-building properties.
TRT (Testosterone Replacement Therapy) utilizes bioidentical testosterone to bring a deficient patient’s levels back to a normal, healthy baseline. “Anabolic steroids” used in bodybuilding utilize supra-physiological doses of testosterone and synthetic derivatives to push levels far beyond human limits.
Chemically, yes. Estrogen and progestin used in birth control pills are steroid hormones because they share the four-ring molecular structure. However, they are female sex hormones and are entirely different from muscle-building anabolic steroids.
