Low Blood Pressure (Hypotension) is the major cause of making you feel dizzy or tired. Blood keeps flowing in your blood vessels (arteries, veins and capillaries). A force is always compelling the blood to flow in blood vessels continuously without any break, the force is your blood pressure. When the blood leaves your heart , enters arteries, the blood pressure makes it flow. This means your blood pushes against your arteries with every bet and the pushing force is known as your blood pressure. Measuring units for measuring blood pressure is millimeter mercury also written as mm Hg. Sometimes it goes up, known as high blood pressure or hypertension and sometimes, it drops down and is called Low Blood Pressure or Hypotension.

The normal blood pressure reading is denoted as 120/80 mm Hg. There are two numbers that are representing your blood pressure reading, these are:

  • Systolic Blood Pressure: The top number denotes the pressure of blood recorded when blood leaves your heart and enters arteries. Ventricles of the heart squeeze to push blood into arteries.
  • Diastolic Blood Pressure: The bottom number is used to denote the blood pressure in your arteries when the heart relaxes between heart beats. Studies say that this reading shows your blood pressure when your heart is at rest or noted when blood comes back to your heart.

Your blood pressure doesn’t remain constant throughout the day. It keeps on changing. Changes in blood pressure are usually caused by different factors, such as your health status, diet, and activity level. That’s why the blood pressure goes up and down in response to the factors.

What is Hypotension?

Blood pressure is basically measured as two measurements. The higher measurement shows the readings noted when it strikes against walls of arteries after leaving heart, when your heart beats and the pulse is noted in the periods of rest between your heartbeats. Thus, your blood pressure measurement is the combination of two readings: the systolic pressure and the diastolic pressure.

According to medical researchers, having a low blood pressure is favorable in most cars i.e, below 120/80.

However, experts also explain that hypotension is treated is an underlying health condition that should be managed on an immediate basis. The blood pressure reading below 90/60 is considered as hypotension in adults.

Types of Hypotension

According to the situations when low blood pressure happens and its effects, hypotension is categorized in several ties, such as:

Orthostatic Hypotension

This is also known as postural hypotension. The drop of blood pressure happens due to your posture. For example, your blood pressure drops down when you move from lying down to standing or sitting to standing. This means the change in  position makes you feel lightheaded or dizzy. This hypotension can affect you at any age, but older adults experience this frequently. Because aging catalyzes an overall dropping of blood pressure.

In addition, pregnancy is also a major cause of orthostatic hypotension.

Moreover, certain autonomic nervous system disorders also cause this drop in blood pressure. Such conditions include diabetes, or Parkinson’s disease.

According to medical research reports, around 40% to 50% people develop symptoms of orthostatic hypertension due to other underlying health conditions.

Postparandial Hypotension

When you feel a sudden drop in your blood pressure right after eating, it is categorized as postprandial hypotension. Older adults usually experience this type of low blood pressure. In addition, some types of autonomic dysfunctions also cause obesity.

Neurally Mediated Hypotension

Your body is a systematized unit that works properly if all the sub-units work in symmetrical order. Similarly, your blood pressure remains balanced if the factors affecting it work in balance. The nervous system, body organs and hormones are the sub-units that work together to maintain a normal blood pressure. But if the balance between them gets disturbed, you may experience low blood pressure. When your heart and brain interact with an abnormal, reflex, neurally mediated hypertension happens.

Other causes of neurally mediated hypotension include:

Experiencing a sudden emotional set back, like a shock or fear. This is the reason, people have low blood pressure while going through a surgical procedure like digital cleaning. Standing in one position for the longest time. Most children experience this form of low blood pressure.

Severe Hypotension

A shock can cause a sudden drop in blood pressure. This type of low blood pressure often happens due to serious life accidents, injury or infection. The shock affects the working of your body organs and coordination system. That’s why the body organs can’t get the blood and oxygen supply that they need to function properly. If the shortage of blood or oxygen becomes severe the hypertension may become life threatening.

Other Types

Sometimes, it happens that certain medications cause permanent drops in blood pressure all the time. Medicines used to treat high blood tissue usually cause severe hypertension.

In addition, some underlying health conditions that affect functioning of heart, liver, nervous system or hormones just cause an overall drop in blood urea leading to severe hypertension.

Moreover, vitamin deficiencies are also a great cause of low blood pressure.
