  3. Alcoholism: Excessive alcohol consumption can interfere with vitamin A metabolism.
  4. Liver Diseases: Liver disorders can disrupt the storage and release of vitamin A.
  5. Inadequate Fat Intake: Vitamin A is fat-soluble, so a very low-fat diet can lead to deficiency.
  6. Intestinal Surgery: Surgical procedures affecting the intestines can affect vitamin A absorption.
  7. Zinc Deficiency: Zinc is essential for converting vitamin A into its active form.
  8. Protein Deficiency: Adequate protein is needed for transporting vitamin A in the blood.
