Original title:
oral iron, drink more orange juice
iron is one of the essential trace elements of the human body, its role is significant, mainly involved in hemoglobin and myoglobin synthesis, to ensure the delivery of oxygen and nutrient storage. Iron is also an important component of cytochrome and cytochrome oxidase, which has important effects on breathing and energy metabolism. In addition, iron can also catalyz the body redox reaction and a variety of enzyme activities, to assist the body to complete various physiological functions. Iron deficiency and the resulting iron deficiency anemia are one of the major nutritional deficiency diseases in China, which has a particularly serious impact on pregnant, lactating and growing children.
, oral iron supplementation is more commonly used than intravenous iron supplementation because it is safe, economical and convenient. Oral iron agent mainly in the form of two-price iron salt (Fe2 plus) in the heteum and empty intestine absorption, once its oxidation to Fe3 plus, absorption and utilization will be greatly reduced. Oral iron supplements are mainly iron sulfate, iron sulphate, iron glucosic acid, iron fumarate and other "iron", in the weak acid media, the above-mentioned "iron" is the most easily absorbed. The pH of the human intestine is weakly alkaline, which is not conducive to iron absorption, while vitamin C regulates the pH of the intestinal environment. Therefore, taking 100 mg of vitamin C, or half a cup of orange juice, while taking iron ornate can promote iron absorption.
Also note when oral iron supplementation: 1. If there is no obvious gastrointestinal reaction, it is not recommended to take iron with food; 2. Iron should be taken 2 hours before taking antaminics (e.g. sodium bicarbonate), or 4 hours after taking antaminics, iron deficiency and mild, moderate anemia patients are mainly treated with oral iron, and improve diet, eating iron-rich foods such as lean meat, animal internal organs, etc. Fresh fruits, leafy greens, carrots and other vitamin C-rich foods can promote better absorption of iron. 4. For patients with poor oral absorption, inability to withstand oral iron, iron demand exceeding the maximum amount of oral iron can be satisfied, or poor compliance with oral iron, should be replaced with intravenous iron supplementation as soon as possible.
