In the thesis are described main causes and consequences of vitamin and mineral deficiency in patients with inflammatory bowel disease. Inflammatory bowel disease, including Crohn's disease and ulcerative colitis, causes malabsorption in the gastrointestinal tract. Micronutrient deficiency can be a result of blood loss, chronic diarrhea, dysfunction or resection of certain parts of bowel. In addition, patients often try different diets to control the disease, with exclusion of wheat and dairy products, fruits and vegetables etc. The most common complications of inflammatory bowel disease are vitamin and mineral deficiencies. Vitamin D, vitamin K and calcium deficiency can lead to osteoporosis and osteopenia. Iron, vitamin B9 and B12 deficiency can cause anemia and hypercoagulability. Regular screening for certain deficiencies and maintaining a good nutritional status of patient is extremely important because it can affect the course of disease, improves chances of successful treatment and it also improves patient’s quality of life.
