Effects of Glucocorticoid Steroid Therapy on Bone Health

• Bone Mineral Loss: Long-term or high-dose glucocorticoid therapy significantly accelerates the loss of essential minerals, particularly calcium, leading to reduced bone density.
• Suppression of Bone Formation: Steroids inhibit the activity of osteoblasts, which are the cells responsible for building new bone tissue.
• Increased Bone Resorption: They stimulate osteoclasts, the cells that break down and resorb bone, creating an imbalance where bone destruction outpaces formation.
• Risk of Osteoporosis: This dual action drastically increases the risk of developing glucocorticoid-induced osteoporosis (GIOP), making bones fragile and prone to fractures, especially in the spine and hips.
• Impaired Nutrient Absorption: Steroids negatively interfere with the intestinal absorption of calcium and its utilization within the body, further compromising skeletal integrity.
• Nutritional Support: Maintaining adequate intake of calcium, magnesium, and Vitamin D is critically important during steroid therapy to help mitigate these adverse skeletal effects.
