How long does it take for the fetus to absorb the food that a pregnant woman eats?

Everyone understands that things cannot be accomplished overnight. Just like eating something cannot be digested and absorbed immediately, the nutrients in it cannot be digested and absorbed by the human body all at once. So we need to wait. However, many people want to know: How long does it take for the fetus to digest a meal after the pregnant woman eats? In this way, pregnant mothers can grasp the method as soon as possible to make the baby grow better.

How long does it take for a pregnant woman's baby to digest and absorb a meal?

Pregnant women take food and it goes through a process of digestion and absorption by themselves, and the fetus absorbs nutrients through the embryo. Therefore, it is impossible to determine how long it will take the fetus to digest the food you eat.

1. Where do the nutrients for the fetus come from? In the uterus, all the nutrients needed for the fetus's development are transported by the fetal umbilical cord, and the blood in the fetal umbilical cord comes from the embryo.

Embryo: The structure of the embryo is relatively complex, and it has two blood circulatory systems: one set is connected to the mother's blood and respiratory system, and the other set is connected to the fetus's blood and respiratory system. The two blood circulation systems circulate in separate closed pipes and merge with each other, but can exchange substances.

The nutrients and carbon dioxide needed by the fetus enter the fetal blood from the pregnant mother's blood; while the fetal metabolic waste and carbon dioxide enter the pregnant mother's blood from the fetal blood and are excreted from the body through the blood circulation system.

2. Not all nutrients in the pregnant mother's body come from diet.

The source of nutrients in the blood is quite complex: one part comes from the diet, and the other part comes from the mutual coordination among various internal organs. Blood transports nutrients to corresponding organs and tissues of the human body for use or storage. For example: transporting carbohydrates (protein) and glucose to each organ of the human body for use, transporting calcium to bones for storage, etc.

In addition, the internal organs of the human body also need to exchange and provide nutrients to each other. This is also transported by blood, such as the glucose produced by the decomposition of glycogen in the liver is transported to the brain for use, and the fat produced by the liver is transported to the adipose tissue for storage. As parts of the pregnant mother, the embryo and fetus always have priority over the support of other human organs.

For example: if the expectant mother does not take in enough calcium, the calcium in the bones will be stimulated, transported to the embryo by the blood, and finally enter the bones of the fetus to ensure its growth and development; if the mother cannot eat on time and the blood sugar level is high due to diet, the glycogen stored in the liver will be dissolved into glucose and transported to the embryo by the blood for the fetus to use.

3. Even if the expectant mother eats a lot, the fetus will not get much. What the fetus uses directly is not the food eaten by the mother, but the mother's blood.

Blood is only a "transporter" of nutrients, not a "storage device". Therefore, even if the expectant mother takes in a lot of nutrients, they will not be stored in the blood, but will be stored in other organs and tissues of the human body.

Therefore, expectant mothers are advised not to eat too much, otherwise it will be very harmful to their health.
