Does a fetus really urinate in its mother's womb and drink its own urine? Isn't it harmful to his health?

The answer is
This may sound shocking or a bit disgusting, but we've all been swimming and drinking our pee before we were born, but it's not as bad as you often imagine!
During pregnancy, the fetus is surrounded by a fluid called amniotic fluid.
This liquid has several benefits, for example:
- Facilitate the movement of the fetus, which helps the development and growth of muscles.
- Protecting the fetus from trauma when the mother is exposed to any injury.
- Contribute to the formation and maturation of the digestive system; The fetus swallows it and is later absorbed from the intestine.
- Contains proteins, carbohydrates, and minerals necessary for the growth of the child during pregnancy; As these substances are absorbed from his digestive system to benefit his body.
Some studies indicate that the amniotic fluid is responsible for the maturation of the lungs and the formation of the lining layer of the alveoli, which facilitates gas exchange and prevents the walls of the alveoli from sticking when exhaled.
It also has several diagnostic benefits; It is used to diagnose some types of genetic abnormalities before birth.
What is the relationship of amniotic fluid to urine then?
At the beginning of pregnancy, this fluid consists of the mother’s blood plasma, which is transmitted to the sac that contains the fetus as a result of the difference in osmotic pressure between them, and then moves into the fetus’s body through the skin in the first months of pregnancy, and through the digestive system later.
When the kidneys form and begin to excrete urine, the urine mixes with the amniotic fluid, and most of it is; The kidneys also secrete some hormones, minerals, and some substances important for growth; It contributes to the complete development of the fetus when it drinks it later; It is absorbed by the intestines, then excreted through the kidneys to be drunk again, and so on.
What if there is low amniotic fluid?
Low levels of amniotic fluid, referred to as oligohydramnios, occur in 4 percent of all pregnancies and 12 percent of pregnancies after the due date.
Oligohydramnios is present when the amniotic fluid index (AFI) on ultrasound is less than 5 cm (normal index is 5-25 cm) and the maximum vertical sinus (MVP) is less than 2 cm.
This may be evident in cases of fluid leakage from a rupture of the amniotic membranes, a small measure of a certain stage of pregnancy, or if the fetus is not moving as much as expected.
It may also occur in mothers with a history of any of the following medical conditions:
- prior growth-restricted pregnancies
- chronic high blood pressure (hypertension)
- problems with the placenta, for example, abruption
- preeclampsia
- diabetes
- lupus
- multiple pregnancies, for example, twins or triplets
- birth defects, such as kidney abnormalities
- delivering past the due date
- other unknown reasons, known as idiopathic

So in answer to a question, yes we all drank our urine before we were born, and there are no health disadvantages to it; Rather, it is considered one of the most important means by which our bodies mature, frankly, the human race is a natural miracle in its creation.
