Eating corn usually does not affect warfarin. However, it is important to avoid overconsumption, which can cause gastric bloating and other digestive discomfort. Warfarin belongs to the bicoumarin class of intermediate-acting anticoagulants, which are mainly capable of competitively opposing vitamin K and thus have an anticoagulant effect. It is mainly used to prevent the formation and development of blood clots, and can also be used as an auxiliary and preventive drug for myocardial infarction and postoperative thrombotic complications. During treatment with warfarin, avoid foods rich in vitamin K, such as pig liver, soy milk and soybeans. Corn, on the other hand, contains components such as protein, fat, sugar, calcium, phosphorus, iron, and carotene, and is not a vitamin K-rich food. Corn can usually be consumed in moderation, but excessive consumption should be avoided to avoid digestive discomfort. All of the above medications should be used under the guidance of a doctor, avoid self-medication to avoid adverse consequences.
