⚠️ Steroid Side Effects

Understanding Steroid Side Effects

Anabolic steroids cause severe, long-lasting, and in some cases irreversible damage. They can lead to early heart attacks, strokes, liver tumors, kidney failure, and psychiatric problems [web:22]. Most data on long-term effects come from case reports documenting serious and life-threatening adverse events [web:22].

A variety of side effects occur when anabolic steroids are misused, ranging from mild effects to ones that are harmful or even life-threatening [web:22]. Most are reversible if the user stops taking the drugs, however others may be permanent or semi-permanent [web:22].

One animal study found that exposing male mice for one-fifth of their lifespan to steroid doses comparable to those taken by human athletes caused a high frequency of early deaths [web:22]. This systematic review synthesizes medical evidence on the full spectrum of steroid side effects across all major organ systems [web:22][web:23][web:24].

Cardiovascular System Damage

Steroid use has been associated with high blood pressure, decreased function of the heart's ventricles, and cardiovascular diseases such as heart attacks, artery damage, and strokes—even in athletes younger than 30 [web:22]. Cardiovascular complications represent the most serious life-threatening consequences of steroid abuse [web:22].

Heart Disease and Attacks

Cardiovascular disease occurs at alarmingly young ages among steroid users [web:22]:

• Early heart attacks: Documented in athletes younger than 30 years old [web:22]
• Decreased ventricular function: Impaired pumping capacity of the heart chambers [web:22]
• Coronary artery disease: Narrowing and blockage of arteries supplying the heart [web:22]
• Myocardial infarction: Complete heart attacks from blocked blood flow [web:22]
• Sudden cardiac death: Unexpected fatal cardiac events [web:22]

Cholesterol Abnormalities

Steroids contribute to cardiovascular disease partly by increasing low-density lipoprotein (LDL) and decreasing high-density lipoprotein (HDL) [web:22]:

• Elevated LDL cholesterol: "Bad" cholesterol that promotes arterial plaque buildup [web:22][web:24]
• Decreased HDL cholesterol: "Good" cholesterol that protects against heart disease drops significantly [web:22][web:24]
• Atherogenic profile: Cholesterol ratios that accelerate atherosclerosis development [web:24]
• Plaque formation: Fatty deposits narrow and harden arteries throughout the body [web:22]

Stroke Risk

Stroke risk increases dramatically among steroid users, even young athletes [web:22]:

• Ischemic strokes: Blood clots blocking brain blood vessels [web:22]
• Hemorrhagic strokes: Bleeding in the brain from weakened blood vessels [web:22]
• Hypertension-related strokes: High blood pressure causing vessel rupture [web:22]
• Young athlete vulnerability: Documented strokes in users under 30 years old [web:22]

Blood Pressure Elevation

Hypertension is common among steroid users and contributes to multiple cardiovascular complications [web:22][web:24]:

• Systolic hypertension: Elevated upper blood pressure reading [web:22]
• Diastolic hypertension: Elevated lower blood pressure reading [web:22]
• Persistent elevation: High blood pressure continuing even at rest [web:22]
• End-organ damage: Hypertension damaging heart, kidneys, eyes, and brain [web:22]

Hormonal System Disruption

Steroid use disrupts the normal production of hormones in the body [web:22]. Changes that can be reversed include decreased sperm production, decreased function of the testes (hypogonadism) that leads to low testosterone levels, and shrinking of the testicles (testicular atrophy) [web:22].

Testosterone Suppression

Exogenous steroids shut down natural testosterone production through negative feedback mechanisms [web:22]:

• Hypogonadism: Testes cease producing adequate testosterone naturally [web:22][web:24]
• LH and FSH suppression: Brain signals to testes are shut down [web:22]
• Recovery challenges: Natural production may take months to years to restore [web:22]
• Permanent dysfunction: Some users never fully recover natural testosterone production [web:22]

Testicular Changes

Physical changes to the testes occur during steroid use [web:22]:

• Testicular atrophy: Testicles shrink from lack of stimulation [web:22][web:24]
• Decreased sperm production: Reduced fertility and sperm count [web:22][web:24]
• Infertility risk: Temporary or permanent inability to father children [web:22]
• Structural damage: Long-term changes to testicular tissue [web:22]

Irreversible Hormonal Effects

Certain hormonal side effects are permanent [web:22]:

• Male-pattern baldness: Accelerated hair loss that cannot be reversed [web:22][web:24]
• Gynecomastia: Breast tissue development in men, often requiring surgery for removal [web:22][web:24]
• Testicular cancer risk: Increased risk especially when combined with growth factors [web:22]

Sexual Dysfunction

Sexual health complications are common during and after steroid use [web:22][web:24]:

• Erectile dysfunction: Inability to achieve or maintain erections [web:22]
• Decreased libido: Reduced sex drive during withdrawal [web:22]
• Impotence: Complete inability to perform sexually [web:24]
• Long-term dysfunction: Sexual problems persisting after cessation [web:22]

Liver and Kidney Toxicity

Steroid misuse has been associated with liver damage, tumors, and a rare condition called peliosis hepatis in which blood-filled cysts form in the liver [web:22]. The cysts can rupture, causing internal bleeding and even death in rare cases [web:22].

Hepatotoxicity

Oral anabolic steroids are particularly hepatotoxic due to chemical modifications allowing them to survive first-pass liver metabolism [web:22][web:24]:

• Elevated liver enzymes: ALT and AST levels indicating hepatic stress [web:22][web:24]
• Cholestasis: Impaired bile flow leading to jaundice (yellowing of skin and eyes) [web:22][web:24]
• Hepatic inflammation: Liver tissue swelling and damage [web:24]
• Chronic liver disease: Progressive liver dysfunction from prolonged use [web:22]

Liver Tumors

Both benign and malignant liver tumors are associated with steroid use [web:22]:

• Hepatic adenomas: Benign tumors that can rupture and bleed [web:22]
• Hepatocellular carcinoma: Malignant liver cancer [web:22]
• Tumor rupture risk: Internal bleeding requiring emergency surgery [web:22]
• Fatal outcomes: Life-threatening complications from liver tumors [web:22]

Peliosis Hepatis

This rare but serious condition involves blood-filled cysts throughout the liver [web:22]:

• Cyst formation: Multiple blood-filled cavities within liver tissue [web:22][web:24]
• Rupture potential: Cysts can burst causing massive internal bleeding [web:22]
• Life-threatening hemorrhage: Uncontrolled bleeding leading to shock and death [web:22]
• Rare but deadly: Uncommon but often fatal when it occurs [web:22]

Kidney Damage

Renal function can be compromised by steroid use [web:22][web:24]:

• Kidney failure: Progressive loss of kidney function [web:22]
• Protein in urine: Indication of kidney damage [web:24]
• Acute kidney injury: Sudden decline in kidney function [web:24]
• Chronic kidney disease: Long-term impairment requiring dialysis [web:22]

Psychiatric and Psychological Effects

Anabolic steroid users are more likely than nonusers to report anxiety [web:22]. Moderate to high doses of anabolic steroids are associated with major mood disorders such as mania, hypomania, and major depression [web:22].

Aggression and Irritability

Case reports and studies indicate that anabolic steroids increase irritability and aggression [web:22]:

• "Roid rage": Explosive anger and aggressive outbursts [web:22][web:24]
• Increased violence: More fights and violence toward significant others [web:22]
• Verbal aggression: Hostile and argumentative behavior [web:22]
• Criminal behavior: Increased risk of violent crimes [web:22]
• Relationship destruction: Damaged personal and professional relationships [web:22]

Mood Disorders

Major psychiatric disorders develop in significant percentages of steroid users [web:22]:

• Major depression: Severe depressive episodes, especially during withdrawal [web:22][web:24]
• Mania and hypomania: Elevated mood, grandiosity, and impulsive behavior [web:22]
• Bipolar symptoms: Alternating between manic and depressive states [web:22]
• Anxiety disorders: Excessive worry, panic attacks, and fear [web:22][web:24]

Cognitive and Behavioral Changes

Brain function alterations occur with steroid use [web:22]:

• Impaired judgment: Poor decision-making and risk assessment [web:22]
• Memory problems: Difficulties with learning and recall [web:22]
• Attention deficits: Trouble concentrating and focusing [web:22]
• Personality changes: Alterations in behavior and character traits [web:22]

Body Dysmorphia

Muscle dysmorphia and body image disorders are common among steroid users [web:22][web:24]:

• Distorted body image: Seeing oneself as small despite large musculature [web:22]
• Obsessive training: Compulsive exercise patterns [web:22]
• Continued use despite consequences: Unable to stop despite health problems [web:22]
• Social isolation: Withdrawal from activities and relationships [web:22]

Other Physical Side Effects

Musculoskeletal Effects

Rising testosterone levels normally trigger growth spurts during puberty and also signal bones to stop growing [web:22]. When adolescents take steroids, artificially high sex hormone levels can prematurely signal bones to stop growing [web:22].

• Stunted growth in adolescents: Premature closure of growth plates permanently limiting height [web:22][web:24]
• Tendon stiffness: Stiffer tendons increasing injury risk in weightlifters [web:22][web:24]
• Tendon ruptures: Increased risk of torn tendons and ligaments [web:22]
• Joint pain: Aching joints from structural changes [web:24]

Dermatological Effects

Skin-related side effects are extremely common and visible [web:22][web:24]:

• Severe acne: Cystic acne on face, back, and shoulders [web:22][web:24]
• Oily skin: Excessive sebum production [web:22][web:24]
• Hair loss: Accelerated male-pattern baldness [web:22][web:24]
• Stretch marks (striae): From rapid muscle growth [web:24]
• Jaundice: Yellowing of skin and eyes from liver damage [web:22][web:24]
• Injection site problems: Pain, abscesses, and scarring [web:22]

Infection Risks

Many people who inject anabolic steroids use nonsterile injection techniques or share contaminated needles [web:22]:

• HIV transmission: Life-threatening viral infection from needle sharing [web:22][web:24]
• Hepatitis B and C: Chronic liver infections from contaminated needles [web:22][web:24]
• Bacterial infections: Abscesses and sepsis from improper injection technique [web:22]
• Immune suppression: Steroids weaken immune system increasing infection vulnerability [web:22]

Additional Side Effects

• Voice deepening: Irreversible voice changes, especially in women [web:24]
• Prostate enlargement: Benign prostatic hyperplasia in men [web:24]
• Sleep apnea: Breathing disruptions during sleep [web:24]
• Fluid retention: Edema and water weight gain [web:24]

Dependence and Withdrawal Syndrome

An undetermined percentage of steroid users develop a steroid use disorder [web:22]. Substance use disorders are defined by continued use despite adverse consequences, which for steroid users may include physical or psychological problems [web:22].

Steroid Dependence

A review of research suggests that about 32 percent of people who misuse anabolic steroids become dependent [web:22]:

• Tolerance development: Needing increasingly higher doses to achieve the same effects [web:22]
• Compulsive use: Unable to stop despite wanting to quit [web:22]
• Continued use despite harm: Using even when health problems develop [web:22]
• Loss of control: Using more or longer than intended [web:22]
• Psychological addiction: Feeling unable to function without steroids [web:22]

Withdrawal Symptoms

Withdrawal symptoms occur when steroid use stops [web:22]. Symptoms can be severe and prolonged [web:22]:

• Fatigue and exhaustion: Extreme tiredness and lack of energy [web:22]
• Restlessness: Inability to relax or feel comfortable [web:22]
• Loss of appetite: Decreased desire to eat [web:22]
• Insomnia: Difficulty falling or staying asleep [web:22][web:25]
• Reduced sex drive: Low libido during recovery period [web:22]
• Steroid cravings: Intense desire to resume use [web:22]

Depression During Withdrawal

The most dangerous withdrawal symptom is depression [web:22]:

• Severe depression: Profound sadness and hopelessness [web:22][web:25]
• Suicide risk: Depression sometimes leads to suicide attempts [web:22]
• Prolonged duration: Depressive symptoms may last months [web:22]
• Resumption trigger: Depression often leads users to restart steroids [web:22]

Reversible vs Irreversible Effects

Most steroid side effects are reversible if the user stops taking the drugs, however others may be permanent or semi-permanent [web:22].

Reversible Side Effects

These effects typically improve after steroid cessation [web:22]:

• Testicular atrophy: Testicles usually return to normal size after several months [web:22]
• Decreased sperm production: Sperm counts often recover over 6-12 months [web:22]
• Acne: Skin usually clears after hormones normalize [web:22]
• Fluid retention: Excess water weight dissipates quickly [web:22]
• Elevated blood pressure: Often returns to normal after stopping [web:22]

Irreversible Side Effects

These effects are permanent and cannot be reversed [web:22]:

• Male-pattern baldness: Hair loss is permanent once it occurs [web:22]
• Gynecomastia: Breast tissue in men usually requires surgery for removal [web:22]
• Heart damage: Cardiovascular structural changes persist [web:22]
• Liver tumors: Existing tumors do not disappear [web:22]
• Stunted growth: Premature growth plate closure cannot be undone [web:22]
• Voice deepening in women: Laryngeal changes are permanent [web:24]

Semi-Permanent Effects

Some effects may partially improve but not fully resolve [web:22]:

• Hypogonadism: Natural testosterone production may never fully recover [web:22]
• Infertility: Sperm production may remain impaired long-term [web:22]
• Psychiatric changes: Mood disorders may persist after cessation [web:22]
• Cognitive impairment: Brain function changes may be lasting [web:22]

Risk Factors and Vulnerability

Certain factors increase vulnerability to serious steroid side effects:

High-Risk Populations

• Adolescents: Stunted growth, premature bone fusion, and lasting brain changes [web:22]
• Pre-existing heart conditions: Accelerated cardiovascular disease progression [web:22]
• Family history of heart disease: Compounded cardiovascular risk [web:22]
• Mental health disorders: Exacerbation of existing psychiatric conditions [web:22]
• Liver disease: Further hepatic damage from already compromised organ [web:22]

Dose-Dependent Risks

Higher doses and longer duration increase side effect severity [web:22]:

• Supraphysiological doses: Doses exceeding natural testosterone levels carry highest risks [web:22]
• Stacking multiple compounds: Using several steroids simultaneously multiplies dangers [web:22]
• Long-term use: Cumulative damage increases over time [web:22]
• Cycling patterns: Even cyclical use causes lasting effects [web:22]

Individual Variability

Side effect severity varies significantly between individuals [web:22]:

• Genetic factors: Individual genetic predisposition affects vulnerability [web:22]
• Unpredictable responses: No way to predict who will experience severe complications [web:22]
• Age at first use: Earlier use associated with worse long-term outcomes [web:22]
• Polypharmacy: Combining steroids with other drugs increases unpredictability [web:22]
