There is a very fine line between preeclampsia and pregnancy hypertension. However, it is vital that one be aware of these differences for the safety of both the mother and child. Remember that during the pregnancy period, blood pressure is often checked because high blood pressure is a common sign of preeclampsia. However, there are many other signs that one has to watch out for.
If there is a persistent rise in the blood pressure, the doctor may ask you to undergo a proteinuria test too, which basically tests the urine levels in the body. In case the proteinuria levels are not as per defined norms, there is a chance that you have preeclampsia.
The symptoms of pregnancy high blood pressure and preeclampsia are often the same, but it is tests like these, which help in differentiating between the two. Other symptoms that you may experience during high blood pressure and preeclampsia include weight gain, swelling in the feet, headaches, etc. Considering these are symptoms that occur commonly during pregnancy, discriminating or sorting them out becomes difficult.
But unlike high blood pressure, there are a lot of risks involved in preeclampsia. Diagnosed around the 20th week of pregnancy, this disease may result in the baby not being delivered the right way. In some cases, the baby is not full delivered or is preterm. There are some other serious complications that may occur for the mother too. So it could mean termination of pregnancy for some.
What you should do is keep a watch out for the different kinds of symptoms that are mentioned above. In case, you are unsure or have a bad feeling, you can ask your doctor for a check up or test for proteinuria. In all probabilities, it is just a little high blood pressure that will go away as you get ample rest :)
