Vitamin K deficiency can commonly develop in people who:
- have cystic fibrosis
- have a condition that impairs fat absorption
- have liver disease
People with cystic fibrosis may have difficulty absorbing fat and fat-soluble vitamins, including vitamin K. Conditions that impair fat absorption (such as Crohn's disease, celiac disease, or pancreatitis) can also lead to vitamin K deficiency. Liver disease can affect the synthesis of proteins that require vitamin K, leading to deficiency as well.
While type 2 diabetes can have various complications, it is not commonly associated with vitamin K deficiency compared to the other conditions listed. Therefore, the first three options are correct.
