Aortic coarctation, one of the most aggressive diseases in vascular surgery, can predispose to the risk of death from aortic coarctation rupture if it is not well controlled. For patients with aortic coarctation, the diet needs to pay attention to the following points: First, low sodium diet, low sodium diet is to limit the food containing too much sodium, which can effectively reduce the risk of elevated blood pressure. If blood pressure increases, it will aggravate the development of aortic coarctation, causing the risk of death from continued tearing or rupture of the aortic coarctation. Secondly, balanced diet and balanced diet mainly ensure the balance of vegetables, fruits, meat and eggs, which can effectively ensure the necessary nutritional elements for patients. Third, easy-to-digest food is the main focus, if too much indigestible food is eaten, it will easily lead to constipation, straining to defecate, which will cause abdominal pressure or increased blood pressure, causing the aggravation of the disease. Fourth, abstain from alcohol, as drinking alcohol can increase heart rate and blood pressure, leading to the risk of further tearing or rupture of the aortic coarctation. Therefore, patients with aortic coarctation should pay attention to some of the above eating precautions.
