What will be an ideal response
Many women suffer nausea until their systems become adjusted to elevated levels of hCG, estrogens and progesterone. Heartburn is common due to displacement of the esophagus and crowding of the stomach by the growing fetus in the uterus. Additional wastes from fetal metabolism cause the production of more urine. Due to pressure on the bladder by the uterus, urination is more frequent. Tidal volume increases during pregnancy, as does respiratory rate. Residual volume decreases and many women exhibit dyspnea (difficult breathing). Total body water rises, acting as a safeguard against blood loss during birth. Blood volume increases, blood pressure and pulse rise, and cardiac output increases.
