Steroid addiction involves the continued use of steroids despite negative consequences and an inability to control use. Causes include a preoccupation with body image and performance due to social and media influences. Short-term effects of withdrawal include fatigue, insomnia, mood swings and loss of interest in sex. Long-term effects range from acne and baldness to heart disease and infertility. Treatment in a rehab center uses counseling and medication to manage withdrawal symptoms and underlying causes.
