What type of deficiency is caused by inadequate absorption?

Inadequate absorption can lead to a malabsorption deficiency, where the body fails to adequately absorb nutrients from the diet. This can result in specific deficiencies, such as vitamin B12 deficiency, iron deficiency anemia, or fat-soluble vitamin deficiencies (A, D, E, K). Conditions like celiac disease, Crohn's disease, and certain pancreatic disorders can contribute to such malabsorption issues.
