Causes of High Blood pressure in Pregnancy Preeclampsia
Causes
|
|
Preeclampsia used to be called toxemia because it was thought
to be caused by a toxin in a pregnant woman's bloodstream. Although this theory has been debunked,
researchers have yet to determine what causes preeclampsia.
|
Possible causes may include:
|
|
Uterine ischemia/ underperfusion Insufficient blood flow to
the uterus
Prostacyclin/thromboxane imbalance (ASA) Disruption of the balance of the hormones that maintain
the diameter of the blood vessels.
Endothelial activation and dysfunction Damage to the lining of the blood vessels that regulates the
diameter of the blood vessels keeping fluid and protein inside the blood vessels and keeps blood
from clotting.
Calcium deficiency Calcium helps maintain vasodilation, so a deficiency would impair the function
of vasodilation
Hemodynamic vascular injury Injury to the blood vessels due to too much blood flow,i.e. the garden
hose hooked up to a fire hydrant
Preexisting maternal conditions Mother has undiagnosed high blood pressure or other preexisting
problems such as diabetes, lupus, sickle cell disorder, hyperthyroidism, kidney disorder,
etc.
Immunological Activation The immune system believes that damage has occurred to the blood vessel
and in trying to fix the "injury" actually makes the problem worse (like scar tissue) and augments
the process.
Nutritional Problems/Poor Diet Insufficient protein, excessive protein, not enough fresh fruit and
vegetables (antioxidants), among others theories.
High Body Fat High body fat may actually be the symptom of the tendency to develop this disorder
linked to the genetic tendency towards high blood pressure, diabetes and insulin
resistance.
Insufficient Magnesium Oxide and B6 Magnesium stabilizes vascular smooth muscles and helps regulate
vascular tone. Too much magnesium acts as a laxative and is not absorbed into the
body.
Genetic Tendency
There is nothing that any woman can do to prevent preeclampsia from occurring. Therefore, it is
both unhealthy and not helpful to assign blame and to review and rehash events that occurred either
just prior to pregnancy, or during early pregnancy that may have contributed to the development of
preeclampsia.
