Low Blood Pressure in Children: Causes, Symptoms and Treatment


Feeling dizzy or lightheaded, frequent fainting, having an irregular heartbeat, increased thirst, and lack of concentration are some of the symptoms of low blood pressure in children.

What is low blood pressure?

Blood pressure is an automatically regulated mechanism in our body. It is designed to provide oxygen through the blood, through our brain, as well as to various parts of our body. The regulation of blood pressure falls within many factors. Blood volume can affect the blood pressure, the endothelial wall of the blood vessel itself constricting and dilating through what we call baroreceptors or blood pressure sensitive receptors can help modulate the blood pressure, and of course electrolytes and the sodium balance can also play an important factor.

Low blood pressure, also called hypotension, is blood pressure low enough that the flow of blood to the organs of the body is inadequate.

Cause of low blood pressure in children

One of the main causes of low blood pressure in children is adrenal fatigue. When the blood pressure is not regular, the brain is not getting enough profusion or blood flow, and then the body will suffer. In the case of adrenal fatigue, what happens is, because the adrenal glands regulate the sodium and potassium balance, there is a tendency, as the adrenals get weaker that the body is not able to regulate this as much as it should. As a result, the sodium is usually lost through the deficiency or the subclinical effectiveness of aldosterone: the hormone that is regulating the blood flow and the water flow.

Now, this hormone is critical because in adrenal fatigue this hormone aldosterone tends to be low. As a result, the sodium is not going to be easily maintained in the body. At this time the laboratory values may be the same or normal. Many children suffer from low blood pressure because they are losing sodium. Without sodium, the water inside their body does not flow. So, in other words, the water stays with the sodium, wherever the sodium goes the water goes. So as long as the sodium is high, the water will be retained in the body. When the sodium is low then the body will tend to lose water. If you lose water, then your blood pressure will go down; it will stay down consistently.
