Changing The Body’s Position

Blood pressure can vary throughout the body due to the direct action of gravity. When a person is standing, blood pressure is higher in the legs than in the head, much in the way that the water pressure at the bottom of a swimming pool is higher than that at the top. When a person lies down, blood pressure tends to be more equal throughout the body.

When a person stands up, blood from the veins in the legs has a harder time getting back to the heart. As a result, the heart has less blood to pump out, and blood pressure may temporarily drop throughout the body. When a person sits down or lies down, blood can more easily return to the heart, and cardiac output and blood pressure may increase. Elevating the legs above the level of the heart can increase return of blood to the heart, which increases cardiac output and raises blood pressure.

Common Causes Of Postural Hypotension Include:

  • Age-related drops in blood pressure which certain medications or health conditions may worsen.
  • Electrolyte loss and dehydration due to diarrhea, vomiting, excessive loss of blood during menstruation, and/or other conditions.
  • Certain diseases or disorders that may cause Postural Hypotension such as: Cardiovascular disorders, Central nervous system disorders including multiple system atrophy or Shy-Drager syndrome, Nerve issues such as autonomic neuropathy or peripheral neuropathy, Nutritional disorders.
  • Alcohol intake.

How Does This Condition Affect My Body

Blood Pressure Drop Symptoms : Blood pressure drops when doctors ...

Under normal circumstances, your body can automatically control your blood pressure and keep it from dropping too much. If it starts to drop, your body tries to compensate for that, either by speeding up your heart rate or constricting blood vessels to make them narrower. Symptoms of hypotension happen when your body cant compensate enough to offset the drop in blood pressure.

For many people, hypotension doesn’t cause any symptoms. Many people don’t even know their blood pressure is low unless they get their blood pressure measured.

For people with symptoms, the effects depend on why hypotension is happening, how fast it develops and what caused it. Slow decreases in blood pressure happen normally, so hypotension becomes more common as people get older. Fast decreases in blood pressure can mean certain parts of your body arent getting enough blood flow. That can have effects that are unpleasant, disruptive or even dangerous.

If you have hypotension with symptoms, the best thing you can do is follow your healthcare provider’s guidance on managing this condition. Their recommendations may include any of the following:

  • Manage your diet. Following diet recommendations, especially how much salt you should have in your diet, can help avoid symptoms of hypotension.
  • Take your medication. These can help you avoid the disruptive symptoms and effects of this condition.
  • Dress up. Compression socks, which put light pressure on your legs and feet, can push blood upward and raise your blood pressure.
  • Take it slow. Avoid standing up too quickly, especially with orthostatic hypotension. That can help you avoid the dizziness and fainting effects of hypotension.
  • Have a seat. If you notice yourself feeling dizzy or lightheaded, sit down. Falling from standing height can put you at risk for severe or even catastrophic injuries from a fall, such as a broken hip, concussion, skull fracture or broken ribs.

Low Blood Pressure Symptoms

Reducing your risk of fainting

Low blood pressure 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.

The study, published in the May 7, 2018 Journal of the American Heart Association, tracked more than 9,100 middle-aged adults for more than two decades. Researchers found that people with OH had a higher risk of future heart attack, heart failure, and stroke than those without the condition. They were also more likely to have early signs of heart disease, such as plaque buildup in the carotid arteries and elevated levels of blood proteins indicating heart damage.

Orthostatic hypotension could be a red flag for latent cardiovascular disease. Its important to be aware of this possible link because some of the treatments for OH could make heart disease worse.
