Long-Term Steroid Use and Central Fat Accumulation

• Direct Answer: Yes, long-term use of corticosteroids (such as prednisone, cortisone, or dexamethasone) can indeed cause central fat accumulation, including the characteristic buffalo hump (an abnormal fat pad forming on the upper back between the shoulders).

Why This Happens

• Metabolic Alterations: Corticosteroids significantly alter how the body metabolizes and distributes fat, protein, and carbohydrates.
• Redistribution of Fat: While causing fat loss in the extremities (arms and legs), these medications often stimulate fat deposition in specific central areas of the body, primarily the abdomen, face (moon facies), and the back of the neck (buffalo hump).

Underlying Mechanism

• Hormonal Imbalance: High levels of synthetic steroids mimic the condition known as Cushing's syndrome (often called iatrogenic or drug-induced Cushing's syndrome).
• Lipogenesis: Corticosteroids promote the activity of certain enzymes involved in fat creation and storage while inhibiting the breakdown of fat in central adipose tissues.

Important Considerations

• Dose and Duration: The risk and severity of developing a buffalo hump and other fat redistribution patterns generally increase with higher dosages and longer durations of steroid therapy.
• Consultation: Patients should never abruptly stop or alter their corticosteroid dosage without medical supervision, as doing so can be dangerous. Any concerns regarding body composition changes should be discussed with the prescribing physician to evaluate the risk-benefit ratio of the treatment.
