Arterial pressure in pregnancy is an important symptom that characterizes the course of pregnancy. This indicator may differ throughout pregnancy, and is due to hormonal changes in the body of a pregnant woman. Normal pressure in pregnant women is within 90 / 60-120 / 80 mmHg.
Pressure on early pregnancy
In the early stages of pregnancy, pressure is often reduced due to changes in the hormonal background. Often the first signs of pregnancy can be: general weakness, loss of consciousness, dizziness, nausea, ringing in the ears, increased drowsiness, etc. These complaints are characteristic in the morning. Therefore, low blood pressure during pregnancy can be the first sign of it. Such manifestations of toxicosis as nausea, vomiting, loss of appetite, can help reduce blood pressure during pregnancy.
Pressure in the last month of pregnancy
In the second half of pregnancy, the pressure may increase, as the volume of circulating blood increases and a third circle of blood circulation appears. A change in the pressure during pregnancy in later terms towards its increase suggests a beginning of pre-eclampsia, which disrupts the course of pregnancy and childbirth. With the development of preeclampsia, the increase in blood pressure, usually combined with edema and the appearance of protein in the urine. The terrible complication of preeclampsia is eclampsia, which is in fact a manifestation of cerebral edema and proceeds with loss of consciousness and the development of convulsive seizures. Therefore, in the late stages of pregnancy, daily monitoring of blood pressure and pulse is especially important, and also monitoring proteinuria (protein in the urine) every two weeks. Permissible pregnancy pressure, starting from week 20, should not be less than 100/60 mm Hg. and not higher than 140/90 mm Hg.
How does the pressure on pregnancy affect?
Both a decrease and an increase in blood pressure adversely affect the body of the expectant mother and the course of pregnancy. Thus, a decrease in pressure leads to a deterioration of blood circulation in the placenta and an insufficient intake of oxygen to the fetus, leading to hypoxia and a delay in intrauterine development.
Increase in blood pressure in the second and third trimester of pregnancy is higher than 140/90 mm Hg. is the reason for hospitalization in a specialized hospital. Increased blood pressure disrupts placental blood flow due to placental edema. Thus, the fetus suffers from a lack of oxygen and nutrients. The pressure rise is above the level of 170/110 mm Hg. threatens the development of acute disorders of cerebral circulation. Disturbing symptoms of an increasing clinic of pre-eclampsia is the difficulty of nasal breathing, the flashing of flies before the eyes, a headache and a violation of the level of consciousness.
Pressure jumps in pregnancy can be a symptom of increased intracranial pressure. Increased intracranial pressure during pregnancy is caused by increased production of cerebrospinal fluid in the plexus of the lateral ventricles. Most likely, that the woman and before pregnancy suffered intracranial hypertension, and during pregnancy this pathology became aggravated. In this case, you need to apply to the neuropathologist and check the intraocular pressure.
Eye pressure during pregnancy is checked for specific indications:
- decreased vision;
- increased blood pressure;
- blood pressure jumps.
We can conclude from the above that the pressure and pulse in a pregnant woman are important clinical symptoms by which such formidable complications as preeclampsia, placental abruption, increased intracranial pressure can be identified.
