Low Blood Pressure (hypotension)

Low blood pressure is generally considered as hypotension where the reading is lower than 90 mmHg for (systolic) or 60 mmHg for (diastolic). The low blood pressure might have noticeable symptoms and low blood pressure can be life-threatening.

Types of hypotension

Orthostatic hypotension

This hypotension is also called postural hypotension where the drop in blood pressure occurs when you move from a sitting and lying down position. As per the body, the position changes you may feel a kind of dizziness or light head, some of the other conditions affecting the autonomic nervous system like Parkinson’s disease and diabetes.

Postprandial hypotension

This postprandial hypotension is a drop in blood sugar after the consumption of this symptom is more common in older people and has automatic dysfunction.

Multiple System atrophy

This system of multiple atrophy also called shy-Drager symptoms affects the nervous system, which involves automatic functions like blood pressure, heart rate, breathing issues, and digestive problem this may be related when blood pressure is high and positioned while dying down.

Neurally mediated hypotension

This type of hypotension is generally balanced between the nervous system and other parts of the human body like organs.

This neurally mediated hypotension happens then there is an abnormal reflex interaction between the heart and brain.

Severe

A sudden drop in blood pressure can occur during shock. This can happen if you experience an injury or some kind of infection.

Other types

Some kinds of conditions may affect the heart, liver, hormones, and nervous system. Vitamin deficiencies can also be the reason to lower blood pressure.

Signs of low blood pressure

Hypotension symptoms may include

• Fading vision

• Fainting

• Light-headedness and dizziness

• Lack of concentration

• Nausea and fatigue

For some patients, hypotension may be an indication of a health condition when it drops it may occur with symptoms. A change of just 20mmhg – a drop from 110mmhg systolic to 90mmhg systolic, some conditions can lead to dizziness and fainting. A sudden drop can be caused by uncontrolled bleeding, allergic reaction, severe infection can be life-threatening. If it reaches below the range can lead to Shock.

Some of the symptoms of shock could be

• Cold clammy skin.

• Decrease in skin coloration.

• Week and rapid pulse rate.

• Shallow and rapid breathing.

Causes of hypertension

The causes are determined by the amount of blood pumped by the heart and the amount of confrontation to blood flow in arteries.

The situation during systolic pressure upper range pressure in the arteries when the heart beats

Diastolic pressure is the second bottom range, where the pressure in the arteries and heart rests between breaths.

Conditions that can cause blood pressure are as follow

• Blood loss

Due to injury, losing lots of blood or extreme internal bleeding can reduce blood volume, leading to a severe drop in blood pressure.

• Severe infection and allergies

infection and allergies enter in bloodstream and can lead to a sudden life-threatening, drop-in blood pressure called septic shock.
