Changes in pregnancy
The main changes in the body of a woman during pregnancy occur under the influence of hormones, the ratio of which varies radically.
For example, the yellow body of the ovaries increases the production of progesterone, which not only secures the attachment of the fetal egg to the wall of the uterus, but also makes fat stores in the body of a pregnant woman.
Prolactin hormones and chorionic somatomamotropin make changes in the body of a pregnant woman in the form of an increase in the size of the mammary glands that must be ready for the production of breast milk.
During pregnancy, the abdominal muscles of the woman stretch and become longer, and the lumbar muscles that straighten the spine are shortened. And the volume of blood in a pregnant woman increases by 33-34 weeks by almost a third.
