Alcohol is a factor leading to atherosclerosis, which is not conducive to the recovery of the condition. You should quit smoking and drinking, and eat a light diet with less oil and salt. Alcohol will stimulate the blood vessels, which is not conducive to the recovery of the condition after surgery. Moreover, smoking, drinking alcohol, and eating a greasy diet are all factors that lead to atherosclerosis, which in turn leads to the development of aortic coarctation. Therefore, after surgery for aortic coarctation, you should quit smoking and drinking, eat a light diet, and supplement some high-quality proteins, such as eggs, lean meat and soy products. After the surgery, you should pay attention to regular checkups to prevent related complications, and if you have any discomfort symptoms, you should consult a doctor in time for active treatment and strive for a speedy recovery.
