Blood pressure is low (Hypotension)
Blood Pressure: What Is It?
One of the essential indications of the body is blood pressure (BP). When the heart muscle contracts and relaxes, blood exerts pressure against the blood vessel walls. The pressure in the arteries, the blood channels that transport blood away from the heart, is measured by blood pressure. Blood pressure is partly determined by how well the arteries respond to blood flow.

How Does Blood Pressure Work?
One of the body's key signals is blood pressure (BP). It describes the pressure that blood exerts against blood channel walls when the heart muscle contracts and relaxes. The vessels that transport blood out from the heart is measured by blood pressure in the arteries. Blood pressure is influenced by the arteries' receptivity to blood flow.

Why Is My Blood Pressure Low?
Inadequate blood flow (hypotension) causes the heart, brain, kidneys, and other organs to receive insufficient amounts of oxygen and nutrients. If the damage is permanent, this could be harmful and cause low blood pressure. Low blood pressure in adults is defined as readings below 90/60 mm Hg by some specialists, while.

Every time it beats, the heart pumps blood throughout the body. Systolic pressure is the name given to the force applied to the arteries during a heartbeat. It is the first or highest value used to calculate blood pressure. Diastolic pressure refers to the force applied to the arteries in between heartbeats. It's normal to have a blood pressure reading of less than 120/80 mm of mercury (Hg).
What Causes Blood Pressure to Rise?
Blood that has been oxygenated by the lungs enters the left lower chamber of the heart (ventricle) and is pumped throughout the body. Between heartbeats, the heart fills with blood. Diastole is the name of this stage of the heart cycle. Systole refers to the heart's pumping action as it pushes blood through the arteries.
To feel your heartbeat, place your fingers on the inside of your wrist or the back of your neck. The left ventricle of the heart contracts to give you a pulse.
Exactly how is blood pressure measured?
Blood pressure is influenced by numerous variables. Blood pressure is significantly influenced by two factors: blood volume and blood vessel wall activity. Blood pressure increases when the amount of blood pumped during each heartbeat increases. Blood pressure is also raised by the presence of stiff or narrow arterial walls that obstruct blood flow. Blood pressure is lowered by having open, flexible arteries and a decreased blood volume.
How Does the Body Keep Blood Pressure at a Normal Level?
Little nerve cells called baroreceptors are found in arteries close to the heart and assist in controlling blood pressure. The kidneys, arteries, veins, and other organs can all communicate through baroreceptors.
depending on the situation, the heart can raise, lower, or maintain blood pressure. The baroreceptors' job is to make sure that the body's organs and tissues receive enough blood.
Educated facts about low blood pressure (hypotension)
Low blood pressure, also known as hypotension, is when the blood pressure is so low that the blood flow to the body's organs is insufficient, leading to the onset of symptoms and/or indicators of low blood flow.
Low pressure on its own, without symptoms or warnings, is typically not unhealthy.
Dizziness, fainting, and feeling lightheaded are all signs of low blood pressure. When people go from a laying or sitting position to a standing position, these symptoms become more pronounced (orthostatic hypotension).
Low blood pressure prevents sufficient blood flow to the
Strokes, heart attacks, and kidney failure can be brought on by the body's organs. Shock is the severest kind.
Low blood volume, cardiac disease, and drugs are a few common causes of low blood pressure.
Using blood tests, radiologic analyses, and cardiac testing to check for heart failure and arrhythmias, the cause of low blood pressure can be identified.
The cause of low blood pressure will influence how it is treated.
The signs of low blood pressure
Low blood pressure symptoms, often known as hypotension, can include:
Fainting (syncope) (syncope)
Dizziness
a dizziness-like sensation
an ache in the chest
fuzzy vision
greater thirst
Nausea
What do the numbers on the blood pressure chart (with ranges) mean?
The force that blood flowing through blood arteries applies to their walls is known as blood pressure. It is a component of
example, 120/80.
The systolic blood pressure (the top number) represents the pressure in the arteries as the muscle of the heart contract and pumps blood into them.
The diastolic blood pressure (the bottom number) represents the pressure in the arteries as the muscle of the heart relaxes following its contraction.
Blood pressure always is higher when the heart is pumping (squeezing) than when it is relaxing.
The range of systolic blood pressure for most healthy adults falls between 90 and 120 millimeters of mercury (mm Hg). Normal diastolic blood pressure ranges between 60 and 80 mm Hg. Current guidelines define normal blood pressure range as lower than 120/80. Blood pressures over 130/80 are considered high. High blood pressure increases the risk of damaging the arteries, which leads to the development of:
Heart disease
Kidney disease
Hardening of the arteries (atherosclerosis or arteriosclerosis)
Eye damage
Stroke
Low blood pressure (hypotension) is pressure so low it causes symptoms or signs due to the low flow of blood through the arteries and veins. When the flow of blood is too low to deliver enough oxygen and nutrients to vital organs such as the brain, heart, and kidney, the organs do not function normally and may be temporarily or permanently damaged.
Unlike high blood pressure, low blood pressure is defined primarily by signs and symptoms of low blood flow and not by a specific blood pressure number. Some individuals routinely may have blood pressure numbers of 90/50 with no symptoms and therefore do not have low blood pressure. However, others who normally have higher blood pressure may develop symptoms of low blood pressure if their blood pressure drops to 100/60.
During pregnancy, blood pressure tends to decrease. Normal blood pressure during pregnancy may be lower than 100/60. Your ob-gyn or Midwife should monitor your blood pressure if you are pregnant.
What are the signs and symptoms of low blood pressure?
When blood pressure is not sufficient to deliver enough blood to the organs of the body, the organs do not work properly and can be temporarily or permanently damaged. Symptoms of low blood pressure caused by conditions or diseases depend upon the specific cause of the low blood pressure. For example, if insufficient blood flows to the brain, brain cells do not receive enough oxygen and nutrients, and a person can feel lightheaded, dizzy, or even faint.
The most common symptoms of low blood pressure include:
Lightheadedness
Dizziness
Fainting (syncope)
Symptoms of low blood pressure due to conditions or diseases include:
Orthostatic hypotension symptoms: Going from a sitting or lying position to a standing position often brings out symptoms of low blood pressure. This occurs because standing causes blood to "settle" in the veins of the lower body, and this can lower blood pressure. If the blood pressure is already low, standing can make it worse, to the point of causing symptoms. The development of lightheadedness, dizziness, or fainting upon standing caused by low blood pressure is called orthostatic hypotension. Normal individuals can compensate rapidly for the low pressure created by standing with the responses discussed previously and do not develop orthostatic hypotension.
Heart disease: Chest pain (a symptom of angina) or even a heart attack may occur when there is insufficient blood pressure to deliver blood to the coronary arteries (the arteries that supply blood to the heart's muscles).
Kidney disease: When insufficient blood is delivered to the kidneys, the kidneys fail to eliminate wastes from the body, for example, urea (BUN and creatinine), and increases in their levels in the blood occur.
Shock is a life-threatening condition where persistently low blood pressure causes organs such as the kidney, liver, heart, lungs, and brain to fail rapidly.
