4. Pregnancy
It’s not uncommon for pregnant women to experience low blood pressure. Like virtually every other part of your body changed during pregnancy, so, too, can your blood pressure. While pregnant, a woman’s circulatory system rapidly expands in order to meet the increased metabolic demand of the tissues throughout the body. As a result of the rapid expansion of the circulatory system, the blood that’s pumping through the heart may not be putting enough pressure on the arteries, which can result in lower blood pressure.
It’s most common for pregnant women to experience lower than normal blood pressure during the first 24 weeks of gestation. There are several other factors that can lead to hypotension during pregnancy; dehydration, bed rest for prolonged periods of time, nutritional deficiencies, and anemia, and conditions of the heart (such as those described above), for example, are some factors that can contribute to pregnancy-related hypotension.
