Hypotension is known as low blood pressure. Your blood puts pressure on your artery walls at every heartbeat. And this blood pressure against the arterial walls is referred to as blood pressure.
In the majority of cases, it is good to have a lower blood pressure (below 120/80). However, low blood pressure can sometimes result in fatigue and dizziness. In such cases, hypotension can be an indication of an underlying disease that needs to be treated.
Systole provides blood to your body, and diastole provides blood to your heart as it fills the coronary arteries. Blood pressure is indicated with the systolic number over the diastolic number. Hypotension among adults is defined as a blood pressure of 90/60 or less.
Blood pressure is determined when your heart is beating or pumping blood and during periods of rest between the heartbeat or the relaxing of the heart. The pressure while pumping blood into your arteries when the ventricles of the heart contract is referred to as systolic pressure and pressure in rest periods is referred to as diastolic pressure.
What causes hypotension?
The blood pressure of each one goes down at one time or another. And, in many cases, it does not produce remarkable symptoms. Some conditions may cause extended periods of hypotension which may become threatening if not treated. The following conditions apply:
- pregnancy, as a result of increased blood requirements of the mother and the growing fetus.
- Significant blood loss due to injury.
- decreased circulation as a result of heart attacks or faulty heart valves.
- weakness and shock, which sometimes comes with dehydration.
- anaphylactic shock, a serious form of allergic response.
- bloodstream infections
- endocrine-related disorders such as diabetes, adrenal insufficiency and thyroid.
Drugs may also reduce blood pressure. Beta-blockers and nitroglycerine are medications used to treat heart disease, are the common cause of hypotension. Diuretics, tricyclic antidepressants and erectile dysfunction medicines may reduce blood pressure.
Some people suffer from low blood pressure due to unknown reasons. This type of hypotension, known as chronic asymptomatic hypotension, is usually not harmful.
People suffering from low blood pressure may experience symptoms when their blood pressure drops below 90/60. Symptoms of hypotension may involve:
Symptoms may vary in seriousness. Some people may feel uncomfortable, whereas others may feel very sick.
Types of hypotension
Hypotension is categorized in many different classifications depending on when your blood pressure goes down.
Orthostatic hypotension is a decrease in blood pressure that occurs when moving from a seated or lying position to a standing position. This is common with people of any age.
As the body adjusts to the change in position, a great period of dizziness can occur. This is what some people call “seeing stars (spots of light)” when they get up or switch positions quickly.
Postprandial hypotension is a reduction in blood pressure that happens right after eating. It’s called orthostatic hypotension. Older adults, especially those who have Parkinson’s disease, are more potent for developing postprandial hypotension.
Neural hypotension takes place after a long period of time. It is more common in children than in adults. Emotional events may also cause a decrease in blood pressure.
Serious hypotension is related to shock. Shock happens when your organs are not receiving the blood and oxygen needed to function properly. Severe hypotension may cause death if left untreated immediately.
Treatment for hypotension
Your treatment will vary according to the root cause of your hypotension. Treatment may include medicines for heart disease, diabetes and infection.
Drink enough water to prevent hypotension from becoming dehydrated, especially if you vomit or have diarrhea.
Staying hydrated can also assist in curing and preventing symptoms of neural-mediated hypotension. If you suffer from low blood pressure for a long time, be sure to take a break to sit. and try to reduce stress levels in order to avoid emotional trauma.
Treatment of orthostatic hypotension with slow and progressive motion. Instead of getting up quickly, place yourself in a sitting or standing position with small moves. You can also prevent orthostatic hypotension by not crossing your legs when you are seated.
Low stress due to shocks is the most dangerous form of this condition. Severe hypotension should be deal with rapidly. Emergency staff will provide you with fluids and perhaps blood products to increase your blood pressure and normalize your vital signs.
