The safety of taking steroids depends entirely on which type you’re talking about and why you’re using them. There are two fundamentally different categories: corticosteroids, which are prescribed for conditions like asthma and arthritis, and anabolic steroids, which mimic testosterone and are sometimes misused to build muscle. Corticosteroids carry real but manageable risks under medical supervision. Anabolic steroids used without a prescription pose serious dangers to your heart, liver, hormones, and mental health.
Corticosteroids vs. Anabolic Steroids
These two drug classes share a name but do very different things in the body. Corticosteroids (like prednisone or hydrocortisone) reduce inflammation and suppress immune responses. Doctors prescribe them for autoimmune diseases, severe allergies, asthma flares, and joint inflammation. Anabolic-androgenic steroids are synthetic versions of testosterone. They increase muscle protein synthesis and are legitimately prescribed in narrow cases, such as delayed puberty or muscle-wasting diseases, but the vast majority of non-medical use is for physique or athletic performance.
If your doctor prescribed a corticosteroid, the risks are well understood and your dose is being managed. If you’re considering anabolic steroids without a prescription, the risk profile is far more serious.
Short-Term Risks of Prescribed Corticosteroids
Even a few days on oral corticosteroids can produce noticeable side effects. Blood sugar rises because the drug alters how your body processes glucose, though levels typically return to normal after you stop. Blood pressure often increases temporarily. Many people experience mood shifts ranging from anxiety, restlessness, and insomnia to, at higher doses, more severe reactions like mania or depression. One older but widely cited study found psychiatric symptoms in about 1.3% of patients on lower doses, jumping to 18.4% in those on the highest doses.
Wound healing slows while you’re on the medication, and your body excretes more calcium and uric acid through the kidneys, which can contribute to kidney stones. These effects are generally reversible once you taper off.
Long-Term Corticosteroid Use and Bone Loss
The most significant risk of staying on corticosteroids for months or years is bone thinning. Prolonged use increases the risk of hip fracture by roughly 60% and vertebral (spinal) fracture by about 160%, and that risk is similar regardless of your age or sex. Your doctor may monitor your bone density with imaging scans if you’re on long-term therapy, particularly if you develop back pain, lose height, or develop a hunched posture.
Stopping corticosteroids abruptly after extended use is its own problem. Your adrenal glands, which produce natural stress hormones, effectively go dormant while the medication does their job. Quitting suddenly can trigger steroid withdrawal syndrome: fatigue, nausea, loss of appetite, joint pain, weakness, weight loss, and sometimes fever or mood changes. This is why doctors taper the dose gradually rather than stopping all at once.
How Anabolic Steroids Damage the Heart
The cardiovascular effects of anabolic steroids are among the most dangerous and least reversible. The heart muscle itself can thicken in response to supraphysiological testosterone levels, a condition called cardiac hypertrophy. Imaging studies comparing long-term users to non-users consistently show this abnormal thickening, and clinical case reports have documented scarring of the heart muscle even in users with otherwise normal coronary arteries. Over time, the thickened, scarred heart loses its ability to pump efficiently, which can progress to heart failure.
Blood pressure elevation is common during use, driven partly by the kidneys retaining extra sodium and water. Some studies have found that elevated blood pressure can persist for 5 to 12 months after someone stops using anabolic steroids. Autopsy reports of sudden cardiac deaths among steroid users frequently reveal enlarged, damaged hearts as the underlying cause.
Liver Damage From Oral Anabolic Steroids
The liver is packed with androgen receptors, making it especially vulnerable to anabolic steroids. Oral forms like oxymetholone and stanozolol are particularly toxic because they pass directly through the liver during digestion. The range of damage spans from mildly elevated liver enzymes (which may produce no symptoms at all) to bile flow blockages, fatty liver disease, liver tumors, and in documented cases, liver cancer with multiple growths. One case report linked stanozolol use to hepatocellular carcinoma with multiple adenomas, while another showed liver enzyme levels more than ten times the normal range from injectable use alone.
Hormonal Shutdown and Recovery
Anabolic steroids flood the body with synthetic testosterone, which signals the brain to stop producing its own. The pituitary gland dials back its release of the hormones that tell the testes to make testosterone and sperm. The result is a state of artificially induced hormonal shutdown.
After stopping, recovery is possible but slow. Testosterone levels take roughly 3 to 6 months to approach baseline in most studies, though some individuals need 12 to 15 months. The signaling hormones from the pituitary gland (LH and FSH) generally recover within 3 to 6 months, but full recovery isn’t guaranteed for everyone. During this gap, users commonly experience fatigue, low sex drive, depression, and loss of the muscle mass they gained, which often drives them back to using.
Psychological Effects and “Roid Rage”
Anabolic steroid users report significantly more anger, irritability, and verbal and physical aggression than non-users, including violence toward partners. The term “roid rage” is colloquial but reflects a real pattern. At moderate to high doses, anabolic steroids are associated with major mood disorders including mania, hypomania, and major depression. The effects aren’t uniform: most users in controlled studies showed relatively little psychological change, while a smaller subset experienced dramatic shifts, making it hard to predict who will be affected.
Depression during withdrawal is the most dangerous psychiatric risk. The crash in testosterone after stopping, combined with the loss of the euphoric and energizing effects of the drugs, can be severe enough to lead to suicidal thoughts.
Specific Risks for Young Users
Adolescents and teenagers face a unique danger that adults don’t. The long bones in your arms and legs grow from areas called growth plates, which are still open during puberty. Anabolic steroids cause these growth plates to fuse prematurely, permanently stunting height. This effect is irreversible. Beyond that, younger users experience the same hormonal suppression, liver stress, and cardiovascular strain as adults, with the added vulnerability of a body still in development.
Roughly 25% of adolescent anabolic steroid users who inject share needles, which carries risks of HIV, hepatitis B, and hepatitis C. Documented infectious complications from non-medical steroid injection include abscesses at the injection site and, in rare cases, systemic infections.
The Bottom Line on Safety
Corticosteroids prescribed by a doctor for a specific condition are generally safe when used at the lowest effective dose for the shortest necessary time, with proper tapering. The side effects are real but predictable and manageable. Anabolic steroids used without medical supervision carry risks to virtually every organ system: the heart thickens and scars, the liver accumulates damage, natural hormone production shuts down for months, mood becomes unstable, and for young people, growth can be permanently cut short. The risks scale with dose and duration, but there is no established “safe” dose for non-medical anabolic steroid use.
