What are the Dangers of Low Blood Pressure
Low blood pressure refers to the condition of abnormally low pressure exerted by the circulating blood on the arterial wall. This condition can give rise to some really grave situations. Discover more about the dangers of lower blood pressure with this article.
Though much attention has been paid to the risk associated with high blood pressure, low blood pressure can be equally dangerous. Dangerously low blood pressure for a prolonged duration can deprive the vital organs, like the heart and the brain, from oxygen and cause extensive damage. Therefore, it is very important to monitor the level of blood pressure, especially if you witness the signs of low blood pressure. Here is an account of some of the really serious conditions that can be caused by low blood pressure.
Dangers of Lower Blood Pressure
One of the main dangers of lower blood pressure is reduced flow of blood through the arteries and veins. This can seriously impair normal blood circulation to other parts of the body including the brain, kidney and liver. In the case of insufficient supply of blood and oxygen, the organs cannot work properly. As for example, if the kidneys do not get sufficient amount of blood and oxygen, they cannot completely eliminate the waste material like urea and creatinine, from the body, leading to a consequent rise in their levels. If blood pressure is so low that it even fails to deliver enough blood to the coronary arteries, then there is a probability of developing chest pain and even a heart attack.
A person with significantly low blood pressure is likely to experience frequent fainting spells, palpitations, lightheadedness, blurred vision, dizziness, cold and clammy skin and rapid breathing. Abnormally low blood pressure can also affect the level of concentration and general well-being of an individual by causing nausea, weakness and fatigue. Shock is the most serious condition associated with prolonged low blood pressure, where failure of vital organs like kidneys, liver, heart, lungs and brain can occur due to oxygen and nutrient deprivation caused by the poor circulation of blood.
Causes of Low Blood Pressure
Hypotension or low blood pressure, is mainly caused by a reduction in the volume of blood due to conditions like hemorrhage or excessive loss of blood. It can also be caused due to low intake of fluids as well as loss of fluids or dehydration. Diseases like congestive heart failure and myocardial infarction can cause low blood pressure by reducing cardiac output. In many instances, hypotension is caused by the overuse of certain medications like diuretics and hypertension medications, such as beta blockers, calcium channel blockers and ACE inhibitors. Some other causes of low blood pressure are high levels of acid in the blood, infections like sepsis, low levels of oxygen in the blood as produced by the conditions like asthma and pneumonia.
The treatment of low blood pressure is determined by the underlying causes. Proper monitoring of the signs and symptoms of low blood pressure could play an important role in warding off the dangers associated with the condition. It is also important to avoid overuse of hypertension medications, as it is one of the most significant causes that can dangerously lower blood pressure to an abnormal level.
