There are no special dietary contraindications for patients with aortic coarctation, but the general principle is to eat a light diet and not to consume too much salt and greasy food every day, as salt and greasy food can elevate the blood pressure and aggravate the burden on the heart, which can lead to poor control of the blood pressure and put patients with aortic coarctation at risk. It is also recommended to eat more fiber-rich vegetables and fruits, vegetables such as celery, spinach, etc., and fruits including apples, pears, bananas, oranges, etc. These fiber-rich foods can promote gastrointestinal peristalsis and reduce abdominal bloating and constipation caused by bedridden patients with aortic coarctation. Once aortic coarctation patients are constipated, straining to defecate can lead to an increase in blood pressure, causing aortic coarctation rupture, which is a higher risk.
