Can steroids cause vitamins deficiency in dogs?

Steroids, particularly corticosteroids, can have several side effects in dogs when used long-term or in high doses. While they do not directly cause vitamin deficiencies, they can contribute to conditions that might lead to or exacerbate nutritional imbalances. Here are some ways steroids can affect a dog’s nutritional status:

Altered Metabolism:

• Protein Metabolism: Corticosteroids can cause muscle breakdown, leading to increased protein requirements.
• Fat Metabolism: They can cause fat redistribution and increased fat breakdown, potentially affecting lipid-soluble vitamin status (Vitamins A, D, E, and K).

Increased Appetite and Weight Gain:

• Dogs on steroids often experience increased appetite, which can lead to overeating and obesity. Obesity can result in nutritional imbalances and increased stress on joints and organs.

Calcium and Vitamin D:

• Long-term steroid use can interfere with calcium absorption and metabolism, potentially leading to conditions like osteoporosis. This can indirectly affect Vitamin D status, as calcium and Vitamin D metabolism are closely linked.

Electrolyte Imbalance:

• Steroids can cause sodium retention and potassium loss, leading to imbalances that might affect overall nutritional status and health.

Gastrointestinal Issues:

• Steroids can increase the risk of gastrointestinal ulcers and other digestive issues, potentially affecting the absorption of various nutrients, including vitamins.

While steroids themselves do not directly cause vitamin deficiencies, their impact on metabolism, appetite, and gastrointestinal health can lead to secondary nutritional imbalances. Monitoring and managing the dog’s diet and overall health is important during steroid therapy.
