Holy Pregnancy Vasodilation, Batman!! Did you know that during pregnancy that the blood vessels dilate, which decreases blood pressure? It can cause fainting!!

Changes in the Body

Between the period of the pregnancy, there are changing of:

· Centre of gravity

· Cardiac changes

· Renal function changes

· Body water metabolism

· Respiratory changes

It's a whirlwind of change! But I've got you covered!

Important Issues

Here are some of the most important things to be aware of with fainting during pregnancy:

· Because blood pressure drops due to Vasodilation, it means that there is a risk of fainting when moving from sitting to standing, or from lying to standing. So, take your time moving from one position to the next, or if you are going from lying down to standing, put in a seated exercise.

· Because of blood pressure dropping reaching the arm up over the head can also create a dizzy feeling and/or fainting. If you or your client suffers from this then do not take the arm up over the head!

· Other causes of fainting or feeling faint is the uterine pressure of the inferior vena cava, which is one reason why we now do not exercise lying on the back from 16 weeks. (The inferior vena cava is a large vein that carries deoxygenated blood from the lower and middle body into the right atrium of the heart).
