Some expectant women experience drop in their blood pressure during pregnancy, especially in the first weeks casing dizziness very often and they might even reach to the limit of being faint. However, low blood pressure, also known as hypotension, may not be as dangerous for pregnancy as high blood pressure.
The pregnant women may face it during the first 24 weeks, particularly in the second trimester between weeks 12 and 24. Normally it is caused by the pregnancy itself. When blood circulates and reaches to the fetus as well, the circulatory system of the woman is forced to work faster to fulfill the necessities of the baby being a reason of drop in the blood pressure. As the body stabilizes and adjusts to this situation, it will be having hypotension.
Another cause of hypotension during pregnancy is the pressure of uterus on aorta and vena cava. Therefore, the gynecologists make a suggestion for the pregnant women that they should not sleep on their back, but lie on the left side.
The normal blood pressure is considered when the values are around 11-7 (115 systolic pressure, generated by heart to pump blood to body’s arteries and 75 diastolic pressure, the pressure when heart is at rest between beats). Hypotension may be considered if the values are below 9-6 (90 systolic and 60 diastolic).
There are other causes of hypotension like endocrine issues and heart problems. In severe cases, it can give a location of hypovolemic shock (hypotension associated with severe dehydration). But these cases are rare and they happen with severe infection, allergic reaction or a huge blood loss. In typical situations, hypotension is not damaging to health.
A major symptom of hypotension is dizziness. When the expectant is lying or sitting for a while, giddiness may be felt all through the day. It has also been also noticed that they feel tired, constant fatigue and very sleepy. In some cases, they may feel depressed to some extent.
Another symptom of hypotension during pregnancy is the difficulty of concentration. They may have to read the same thing twice to understand what they read as it is very common in these cases. The vision can also be affected and many pregnant women with low blood pressure experience blurred vision.
Moreover, low blood pressure can cause fainting as well and it occurs when there is sharp and sudden drop in the blood pressure. At such a time, brain longer receives the appropriate level of oxygen, which causes fainting.
- Don’t change position suddenly and rapidly. Instead, make slow movements, especially while changing the posture i.e. from sitting to standing or lying to sitting.
- You should carry a water bottle in your bag at all times because water and minerals help control hypotension. Additionally, you must always ensure to be hydrated since dehydration causes hypotension.
- Be careful about your diet and include hydrating foods. If you face a drop in blood pressure, eat something rich in glucose. You should eat numerous times in the day and avoid spending too many hours without eating as it can be a cause of low blood sugar.
- Do the recommended exercises to maintain active circulation.
