What are the side effects of steroid use?

Steroid side effects depend on the type used, the dose, and how long treatment lasts, with corticosteroids commonly causing weight gain, mood changes, insomnia, high blood sugar, thinning skin, stomach irritation, and, over time, osteoporosis, cataracts, or higher infection risk, while anabolic steroid misuse is linked to acne, hair loss, liver strain, heart problems, infertility, and aggression. Some effects fade after stopping, but others can persist or require careful tapering, so there are several important factors to consider before assuming a symptom is harmless. See below for the full breakdown of short-term versus long-term risks, warning signs that need urgent care, and which effects differ between men, women, and adolescents. If you are noticing new symptoms while taking or after stopping steroids, it helps to sort out what is expected from what needs attention, and a free, instant symptom check can guide you in minutes. Answering a few simple questions gives you a clearer picture of possible causes and practical next steps to discuss with your doctor.

Explanation

Understanding Steroid Use

Steroids, in a medical context, refer to corticosteroids prescribed to reduce inflammation and treat a range of conditions—from asthma and arthritis to autoimmune disorders. Anabolic–androgenic steroids (AAS) mimic testosterone and are sometimes misused to boost muscle mass and athletic performance. While many people benefit from short-term, physician-monitored steroid therapy, misuse or long-term use can lead to significant health risks.

This article outlines the side effects of steroid use, helping you understand potential risks without creating undue alarm. If you notice any worrying symptoms, consider a free, online symptom check, using the doctor approved Ubie Symptom Checker. Always speak to a doctor about anything that could be life-threatening or serious.


Short-Term Side Effects

Even with prescribed, short-term steroid therapy, some people experience side effects. These often resolve once the medication is tapered off or discontinued, but they can still affect quality of life:

  • Fluid retention
    Puffiness in the face, ankles or hands due to water and salt retention.

  • Weight gain
    Increased appetite and fluid retention can lead to rapid weight gain.

  • Mood changes
    Irritability, anxiety or mild euphoria—sometimes called “steroid mood swings.”

  • Digestive upset
    Heartburn, stomach discomfort or nausea, especially if taken without food.

  • Sleep disturbances
    Trouble falling asleep or staying asleep, resulting from the stimulant-like effect of steroids.


Long-Term Side Effects

Prolonged use or abuse of steroids—especially at high doses—raises the risk of more serious, lasting complications:

Cardiovascular System

  • Elevated blood pressure
  • Unfavorable changes in cholesterol:
    • Increased LDL (“bad” cholesterol)
    • Decreased HDL (“good” cholesterol)
  • Greater risk of heart attack or stroke

Endocrine (Hormonal) System

  • Adrenal suppression
    Body’s natural steroid-making glands slow or stop, leading to fatigue, muscle weakness or low blood pressure if steroids are stopped too quickly.

  • Hormonal imbalances

    • In men: reduced sperm count, testicular shrinkage, breast enlargement (gynecomastia)
    • In women: irregular menstrual cycles, deeper voice, excess hair growth on face/body

Psychiatric/Mood Effects

  • Depression or persistent low mood
  • Aggressive behavior (“roid rage”) or increased irritability
  • Anxiety or panic attacks
  • Difficulty concentrating

Liver Damage

  • Elevated liver enzymes indicating stress or injury
  • Formation of liver cysts (hepatic adenomas)
  • Risk of liver tumors, particularly with oral anabolic steroids

Musculoskeletal System

  • Increased risk of tendon tears or ruptures
  • Stunted bone growth in adolescents
  • Osteoporosis (bone thinning) with long-term high-dose corticosteroids

Dermatologic (Skin and Hair)

  • Acne or oily skin outbreaks, especially on the back and shoulders
  • Thinning skin that bruises easily
  • Stretch marks (striae) on the abdomen, thighs or breasts
  • Increased hair growth on face or body (in women)

Immune System

  • Higher risk of infections due to immune suppression
  • Slower wound healing

Special Considerations

  • Age: Steroid use in children and teens can permanently stunt growth.
  • Preexisting conditions: People with diabetes may find it harder to control blood sugar; those with hypertension or kidney disease face added risks.
  • Dosage and duration: Side effects correlate closely with how much you take and for how long.

Reducing Your Risk

When steroids are medically necessary, your doctor will aim to minimize side effects:

  1. Lowest effective dose
    Using the smallest dose that controls symptoms.

  2. Shortest duration
    Stopping or tapering off as soon as it’s safe.

  3. Alternate-day dosing
    Taking a higher dose every other day to give adrenal glands time to recover.

  4. Local treatment
    Using inhaled, topical or injected steroids directly at the problem site rather than higher-risk oral therapy.

  5. Monitoring
    Regular blood tests to track blood pressure, cholesterol, liver and kidney function.


When to Seek Help

If you or someone you know experiences any of the following, get medical advice promptly:

  • Chest pain, rapid heartbeat or shortness of breath
  • Severe headaches, vision changes or neurological symptoms
  • Unexplained muscle weakness or severe bone/joint pain
  • Uncontrolled blood sugar or blood pressure
  • Signs of infection (fever, chills, persistent cough)
  • Mood changes causing self-harm thoughts or inability to function

For non-urgent concerns, you might consider a free, online symptom check, using the doctor approved Ubie Symptom Checker to help you decide on next steps and gather information before seeing your doctor.


Talking to Your Doctor

Never stop or change steroid doses on your own. Always follow your healthcare provider’s plan for tapering. If you’re concerned about side effects of steroid use, schedule an appointment to discuss:

  • Alternative treatments or therapies
  • Strategies to manage or reverse side effects
  • Safe approaches to start or stop steroid therapy

Your health is too important to leave to chance. Speak to a doctor about anything that could be life-threatening or serious—medical guidance tailored to you is the best way to minimize risks and protect your well-being.
