What Is Considered A Dangerously Low Blood Pressure?

Hypotension, or naturally low blood pressure, affects certain people. However, there can be reason for worry if high blood pressure abruptly falls to low blood pressure. Hypotension, or low blood pressure, may indicate excellent health and a lower risk of heart disease. However, persistently low blood pressure or an abrupt decline in blood pressure can cause alarming symptoms and even life-threatening health issues. So what is considered a dangerously low blood pressure? This article will be focused on answering this question so keep reading to learn.


Understanding Low Blood Pressure

Systolic pressure and diastolic pressure are the two values that make up a blood pressure measurement. The highest, or initial, figure in your blood pressure reading—the systolic pressure—describes the pressure in your arteries as your heart pumps out blood. The bottom figure, or diastolic pressure, represents the pressure in your arteries as your heart fills with blood.


What Is Considered A Dangerously Low Blood Pressure?


It is considered normal to have a blood pressure reading of 120/80 millimeters of mercury (mm Hg) or below. Hypotension is the term used when the blood pressure level is below 90/60 mm Hg and is considered unusually low. Some individuals have blood pressure that is frequently in the hypotensive range but no symptoms and no need for therapy. However, in severe situations, hypotension can lead to a reduction in the amount of oxygen and nutrients reaching your brain and other vital organs, which can ultimately result in a life-threatening shock.

Although there are several forms of hypotension, certain populations are more susceptible than others to encounter it. For instance, older persons are more likely to experience orthostatic (positional) hypotension, which happens when you rise up after sitting or lying down. Orthostatic hypotension can also be brought on by dehydration or blood loss.


Types Of Low Blood Pressure

Orthostatic Hypotension

When someone rises from a sedentary or recumbent position, their blood pressure drops dramatically. Dehydration, prolonged bed rest, pregnancy, certain medical conditions, and some drugs are some of the causes. This form of low blood pressure is rather common among the elderly.


Postprandial hypotension

After eating, this decline in blood pressure happens one to two hours later. Older persons are most likely to be affected, particularly those with high blood pressure or disorders of the autonomic nervous system, including Parkinson's disease. Small, low-carb meals, increased water consumption, and abstinence from alcohol may all assist to lessen symptoms.


Neurally Mediated Hypotension

This is a dip in blood pressure that occurs after prolonged standing. Young people and children are most commonly impacted by this sort of low blood pressure. It might be caused by a breakdown in brain-heart connection.


Multiple System Atrophy With Orthostatic Hypotension

This uncommon condition, also known as Shy-Drager syndrome, affects the neurological system that regulates involuntary processes including blood pressure, heart rate, respiration, and digestion. When you're lying down, it's linked to having really high blood pressure.


When Is Low Blood Pressure Dangerous?

Some individuals have naturally low blood pressure and show no symptoms. However, for people whose blood pressure is typically high, a rapid drop in blood pressure might indicate a problem and result in the symptoms mentioned above.

The process of getting back into an upright position after having spent a significant amount of time lying down

Loss of a lot of blood

Using specific drugs, such as those for treating erectile dysfunction, Parkinson's disease, high blood pressure, heart disease, or Parkinson's, or tricyclic antidepressants

Being diagnosed with a heart condition, such as extremely slow heartbeat, difficulties with heart valves, having a heart attack, or having heart failure

Being diagnosed with a condition related to the endocrine system, such as hypothyroidism, parathyroid disease, Addison's disease (a dysfunction of the adrenal glands), low blood sugar, or diabetes

Having a serious infection that spreads throughout your body and gets into your bloodstream

Severe anaphylaxis, a severe kind of an allergic response that can be fatal

Having a disease of the nervous system that causes your blood pressure to fluctuate

Having an insufficient amount of a necessary nutrient, such as low levels of vitamin B12 and folic acid


Can Low Blood Pressure Make You Feel Tired or Fatigued?

Fatigue, which is described as an overpowering exhaustion and a lack of energy, can be a symptom of having low blood pressure. Chronic fatigue syndrome is a disorder that is characterized by extreme weariness, discomfort, and sleep problems that are frequently made worse by exercise. Research has revealed a connection between low blood pressure and chronic fatigue syndrome.

This particular kind of weariness cannot be cured, although medical professionals may recommend treating the underlying reasons, such as sleep difficulties or mental health problems. Alterations to one's diet as well as sustained effort in physical exercise can be of assistance in the management of low blood pressure.


When To See A Doctor For Low Blood Pressure?

There is often no need for alarm if your blood pressure is consistently on the low side and you do not exhibit any of the symptoms associated with risky conditions. In a similar manner, if you take one blood pressure measurement at home and it comes back abnormally low but you have no other symptoms, you probably do not need to make an appointment with your primary care physician. It is common for your blood pressure to fluctuate throughout time, and it is typical for your body to be able to return your blood pressure to normal once it has deviated from the norm.
