Symptoms Of Low Blood Pressure


Symptoms Of Low Blood Pressure refer to a blood pressure reading below 90 millimeters of mercury (mm Hg), or 60 for the highest number (systolic), and mm, Hg for the lowest number (diastolic).

Low blood pressure may not be a problem for everyone. Low blood pressure may not cause any noticeable symptoms but it can cause fainting and dizziness. Low blood pressure can sometimes be life-threatening.

Low blood pressure can be caused by dehydration or serious medical conditions. Low blood pressure can be caused by many things. If necessary, it should be addressed.


Symptoms Of Low Blood Pressure can be caused by:

  • Postural hypotension (or orthostatic hypotension). A sudden drop in blood pressure after a prolonged sitting or lying down. Dehydration, long-term hospitalization, certain medical conditions, and certain medications are all possible causes. This is a common condition in older adults.
  • Postprandial hypertension. This drop in blood pressure happens within 1 to 2 hours of eating. This is more common in older adults with high blood pressure and autonomic nervous system disorders such as Parkinson’s. It is possible to reduce symptoms by eating small, low-carbohydrate foods, drinking more water, or avoiding alcohol.
  • Hypotension that is not mediated by the Neurally. It occurs when you stand for a long time. This form of low blood pressure is most common in children and young adults. This could be due to miscommunication between the brain and heart.
  • Multiple system atrophy and orthostatic hypotension. This rare disorder, also known as Shy-Drager syndrome is thought to affect the nervous system, which controls involuntary functions like blood pressure, heartbeat, breathing, and digestion. It is associated with high blood pressure when lying down.


Hypotension (Symptoms Of Low Blood Pressure) may be accompanied by symptoms such as:

  • Vision blurred or fading
  • Dizziness and lightheadedness
  • Fainting
  • Fatigue
  • Concentration problems
  • Nausea

Low blood pressure can be a sign that someone has an underlying condition.

Sudden drops in blood pressure could be fatal. Just 20 percent of a change in blood pressure is considered dangerous. mm, Hg A drop of 110 mm, Hg Systolic to 90 mm, Hg Systolic, for instance — can cause fainting and dizziness. Big drops can also be dangerous, especially if they are caused by severe infections or uncontrolled bleeding.

Shock can be caused by extremely low blood pressure. Shock symptoms include:

  • Confusion, especially among older people
  • Cold, clammy skin
  • Diminution in skin color (pallor).
  • Rapid and shallow breathing
  • Rapid pulse and weak

When should you see a doctor?

You should seek emergency medical attention if you experience symptoms such as hypotension (extremely low blood pressure) or shock.

Blood pressure is considered too low by most health care professionals if it causes symptoms. You can experience lightheadedness and dizziness occasionally, but this could be due to a number of things. A correct diagnosis is essential.

Your provider might just check you for low blood pressure if you feel fine but have a tendency to be consistently low. It is helpful to keep track of your symptoms, their timing, and what you are doing.


The amount of blood that the heart pumps and resistance to blood flowing through the arteries determine blood pressure. The mercury value (mm Hg) is used to measure blood pressure. It has two numbers.

  • Systolic Pressure. This is the pressure in your arteries at the time that the heart beats.
  • Diastolic Pressure. This is the pressure in your arteries at rest between beats.

American Heart Association defines ideal blood pressure as normal. Ideal blood pressure is typically lower than 120/80 mm, Hg.

The following factors can affect blood pressure throughout the day:

  • Position of the body
  • Breathing
  • Food and drinks
  • Medications
  • Physical condition
  • Stress
  • Time of day

The night is when blood pressure is lowest and the morning is when it rises. Low blood pressure can be caused by certain health conditions or medication.

Symptoms Of Low Blood Pressure can be caused by certain conditions

Low blood pressure can be caused by:

  • Pregnancy. The rapid growth of blood vessels during pregnancy. These changes can cause blood pressure to fall. Low blood pressure is common during the first 24 weeks. After giving birth, blood pressure returns to its pre-pregnancy levels.
  • Heart conditions and heart valve problems. Low blood pressure can be caused by a heart attack, heart failure, or heart valve disease.
  • Endocrine disorders (hormone-related diseases) Conditions that affect the adrenal glands or parathyroid glands may lead to blood pressure dropping. Blood pressure can be affected by low blood sugar (hypoglycemia), and sometimes diabetes.
  • Hypohydration. The body loses water. This causes a decrease in blood volume. This can lead to blood pressure dropping. Dehydration can be caused by severe vomiting, fever, severe diarrhea, excessive use of diuretics, strenuous exercise, and overuse of them.
  • Blood loss. A lot of blood can cause a significant drop in blood pressure.
  • Severe infections (septicemia) can cause a drop in blood pressure that could lead to death.
  • Severe allergic reactions (anaphylaxis)
  • Insufficient nutrients in the diet can cause low blood pressure and anemia.

Symptoms Of Low Blood Pressure can be caused by medications

Low blood pressure can be caused by certain medications, such as:

  • Water pills (diuretics) such as furosemide, Lasix, and hydrochlorothiazide(Microzide), are available in water pills
  • Alpha blockers, such as prazosin (Minipress)
  • Beta-blockers such as Atenolol, Tenormin, and Propranolol (Inderal. Innopran XL. Hemangeol).
  • Parkinson’s drugs, such as pramipexole or Mirapex (Mirapex), and those containing levodopa
  • Tricyclic antidepressants include certain types of antidepressants, such as doxepin (Silenor), and imipramine(Tofranil).
  • Viagra, sildenafil, and tadalafil are drugs that treat erectile dysfunction. They can be combined with the heart medication Nitroglycerin (Nitrostat (Ni-Dur), Nitromist).

Risk factors

Hypotension can be experienced by anyone. Risk factors for hypotension include:

  • Age. Blood pressure drops after standing or eating are more common in older adults than 65. Children and young adults are most affected by hypotension that is not mediated neurally.
  • Medications. Some medications, such as blood pressure medication, can increase the chance of low blood pressure.
  • Some diseases. Diabetes, Parkinson’s, and other heart conditions can increase the likelihood of low blood pressure.


Hypotension can lead to hypotension, which can cause complications.

  • Dizziness
  • Weakness
  • Fainting
  • Falls-related injury

Low blood pressure can cause severe damage to the heart and brain.
