Gastric or ileal disease can block absorption of vitamin B12. Cystic fibrosis, chronic liver disease, and short-bowel syndrome can impair the absorption of fat-soluble vitamins, such as vitamin E. Liver disease, kidney disease, or malabsorption maladies can trigger a deficiency of vitamin K, which is essential for blood clotting and may help keep bones healthy. A lack of stomach acid -- which often occurs among the elderly -- makes it hard to absorb calcium and vitamin B12 from food. Crohn's disease and conditions that affect the small intestine can interfere with vitamin D absorption. In addition, medications for many health conditions can interfere with the absorption of some vitamins and minerals.
