The anatomical closure of the foramen ovale is 5-7 months after birth, while the functional closure depends on the heart function of the newborn, and the closure will be earlier if the heart function is strong. How to accelerate the closure? It is necessary to strengthen nutrition and physical fitness, and then it is possible to promote the perfection of heart function, as well as heart function, in other words, to feed well. If the heart is strong enough during the first 5-7 months of life, especially if the heart itself is strong enough and grows smoothly, the closure will be complete. Anatomical closure is six months after birth, and if functional depends on the congenital condition of the heart itself. If the heart is congenitally deficient, it can gradually recover after birth, depending on the growth and development of the person and the nutrition of the person.
