Low Blood Pressure: Symptoms, Types, Causes, Risk Factors


You have probably heard that high blood pressure is a big issue. Sometimes low blood pressure can also cause problems.

Blood pressure is the force of the blood pressing on the walls of the arteries. All-time your heart beats, it pumps blood in your veins.

Your blood pressure is most leading when your heart beats and elevates blood. This is called systolic pressure. When your heart is at rest, your blood pressure will drop between beats.

This is the diastolic pressure. Your blood pressure reading uses these two numbers. They are usually written on top of each other or across from each other, such as 120/80. If your blood pressure is 90/60 or less, you have low blood influence.

Unusual people have low BP whole the time. They have no symptoms and their low levels are normal for them.

In other people, blood pressure drops below normal due to a medical condition or certain medications. Some people can develop symptoms of low BP if they get up too quickly.

Low blood pressure is only a problem if it causes dizziness, fainting, or, in extreme cases, shock.

Causes Of Low Blood Pressure

Blood pressure varies from person to person. A drop of just 20 mmHg can cause problems for some people. There are various kinds and causes of low blood pressure.

Exacting hypotension can be caused by immediate blood loss (shock), a severe infection, a heart attack, or a severe allergic reaction (anaphylaxis).

Orthostatic hypotension is caused by an immediate change in body condition. This is most common when switching from landscape to portrait. This type of low BP usually only lasts for a few seconds or minutes.

When this kind of blood pressure sinks after eating, it is called postprandial orthostatic hypotension. This type generally affects older adults, people with high blood pressure, and people with Parkinson’s disease.

Neuromedial hypotension (NMH) usually affects young adults and children. It can happen when a person has been paying for a long time. In general, children outgrow this type of hypotension.

Certain medications can cause low blood pressure, including:

Medications for anxiety
Coronary heart disease
Medications used in surgery
Certain antidepressants
Heart medications

Other causes of low blood pressure are:

Nerve damage from diabetes
Changes in heart rhythm (arrhythmias).
Not drinking enough (dehydration)
Heart failure

Symptoms Of Low Blood Pressure

For some people, low BP indicates an underlying problem, especially when it drops suddenly from signs and symptoms such as:

  • Nausea
  • Fatigue
  • Lack of concentration
  • Shock
  • Dizziness or vertigo
  • Pass out
  • Blurred from obscured vision

Extreme hypotension can result in this life-threatening condition. Signs in symptoms include:

  • Confusion, especially in older people
  • Rapid, shallow breathing
  • Weak in rapid pulse
  • Cold, clammy in pale skin

Types Of Hypotension

Hypotension is divided into different classifications based on when the blood pressure falls.


Orthostatic hypotension is the drop in blood pressure that occurs when you move from sitting or lying down to standing. It is common in people of all ages.

As the body adjusts to the change of posture, there may be a brief period of dizziness. This is what some people call “seeing stars” when they get up.

Postprandial Hypotension

Postprandial hypotension is a decrease in blood pressure that happens immediately after eating. It is a class of orthostatic hypotension. Maturer adults, mainly those with Parkinson’s disease, are more liable to amplify postprandial hypotension.

Neurally Mediated

Neurally mediated hypotension happens after prolonged standing. Children feel this form of hypotension more usually than adults. Severe emotional events can also cause this drop-in Bp.


Severe hypotension is related to shock. Illness happens when your organs don’t get the blood and oxygen they require to function accurately. Severe hypotension can be life-threatening if not handled quickly.

Risk Factor’s

Low BP (hypotension) can affect anyone, although certain types of low BP are more common, depending on your age or other factors:

Certain diseases: Parkinson’s disease, diabetes, and some heart diseases put you at a bigger risk of producing low BP.

Age: Decreases in BP when standing up or after eating occur mainly in adults over 65 years of age. Neuromediated hypotension mainly affects children and young adults.

Medicines: People who take certain medications, such as high BP medications such as alpha-blockers, have a higher risk of low BP.

Treatment Of Hypotension

Your cure will depend on the underlying problem of your hypotension. Treatment may include medications for heart disease, diabetes, or infections.

Drink plenty of water to avoid hypotension from dehydration, especially if you have vomiting or diarrhea.

Staying hydrated can also help treat and prevent the symptoms of nerve-mediated hypotension. If you experience low BP when standing for a long time, take a break to sit down. And try to decrease your tension levels to avoid emotional trauma.

Treat postural hypotension with slow, gradual movements. Instead of getting up quickly, you work in small movements until you are sitting or standing. You can also prevent orthostatic hypotension by not crossing your legs when sitting.

Shock-induced hypotension is the most severe form of the disease. Severe hypotension should be treated immediately. Rescuers will give you fluids and possibly blood products to increase your BP and stabilize your vital functions.


Most people can manage and prevent hypotension by understanding and educating themselves about the condition. Know your triggers and try to avoid them.

And if you have been prescribed any medication, take it as prescribed to raise your BP and avoid potentially harmful complications.
