Low Blood Pressure During Pregnancy : Hypotension

Aku sgt la tak focus sejak preggy ni...Tgh kemas2 meja kat office..Tetiba rasa nak goolge psl low BP ni. FYI, before preggy pun my BP usually very low but there's no major concern so I just ignore it. But when you're pregnant low BP is something unusual. People usually suffer from high BP during pregnancy. Here's some interesting fact I've found all over the Internet :

  1. Low blood pressure, called hypotension in the medical field, occurs when the heart, brain and other parts of the body do not get enough blood after the heart pumps it out, explains Some women have low blood pressure before pregnancy but most women experience at least a slight decrease in blood pressure as a result of the bodily changes from pregnancy. Most cases are mild but if fainting occurs, medical treatment is necessary.
  2. In today’s world of modern times and modern living, a normal blood pressure is considered to be 120/80. If your blood pressure returns a figure such as this, then you are generally in good health (Mine is 90/55 on 1st check-up, 109/59 during 2nd check-up & 90/60 last Wednesday).Hypotension refers to abnormally low blood pressure, and a reading even as little as 20mmHg below normal can result in hypotension.
  3. Women with low blood pressure were generally younger, shorter, lighter, leaner, poorer, and more often a minority, and they gained less weight. ( comment)
  4. One common type of hypotension that occurs during pregnancy is supine hypotension. This occurs when a woman lies flat on her back. The American Pregnancy Association explains that the weight of the uterus rests on the major blood vessels in the body and slows or stops the transport of blood to some areas of the body. This is a temporary type of hypotension that can be alleviated by sleeping on the side or at an incline.
  5. Postural hypotension can occur in all individuals but it is very common in pregnancy. When a woman stands quickly from sitting, squatting or kneeling gravity can slow the speed of blood travel, creating a dizzy sensation from reduced blood pressure, explains the American Pregnancy Association. To avoid this temporary type of blood pressure drop a woman can change position more slowly to reduce the impact gravity has on the blood flow.
  6. When an individual becomes dehydrated she can trigger hypotension, explains This is because water is a critical component of blood cell production. A pregnant woman has a greater blood volume to support herself, the placenta and the baby. When the water levels are too low the heart is still pumping blood but it may not be a high enough quantity to provide for all the parts of the body, which results in hypotension. Pregnant women should drink at least 64 oz. of water per day and sometimes more depending on her health care provider's recommendations. Most women urinate more frequently due to the kidneys eliminating waste from the baby and due to increased pressure on the bladder from the weight of the womb. Frequent urination means a woman must replenish the fluids in her body.
  7. Severe hypotension can occur due to a sudden loss of blood, such as following the birth of the baby. refers to this severe decrease in blood pressure as shock. Most women recover fully from hypotension of this type due to being monitored closely after the baby has arrived. Blood loss is not always significant enough to cause shock.

Tak byk info about low BP during pregnancy. Most website only stressed about high BP (maybe because it's the most common case). Well... I'll keep searching about this. We'll see how this goes... And for those yg bg petua tu.. Thanks guys! :)
