Causes of Low Blood Pressure
Like high blood pressure, low blood pressure or hypotension can also result in some very serious side effects. Causes of low blood pressure are incredibly widespread and include among others: conditions of the nervous system, heart disease, medication, pregnancy and orthostatic hypotension.
It is relatively common for conditions of the nervous system to result in lower than normal blood pressure readings. The reasons behind this are varied and depend on the precise nature of the condition concerned. Peripheral Neuropathy is a debilitating condition whereby the nerves transmitting signals from the brain and spinal cord become severely damaged. Individuals suffering from this condition often experience incredibly low blood pressure levels. Similarly, shock and emotional stress can both result in reduced blood pressure, as can strokes, fits and Parkinson's disease.
Orthostatic hypotension or postural hypotension occurs when the body is brought very quickly to a sitting or standing position after having been in a horizontal position for an extended period of time. This causes blood to drain rapidly from the brain, resulting in dizziness and in some cases loss of consciousness for a brief period of time. This type of low blood pressure is a normal bodily response and is no cause for alarm. It will correct itself naturally and does not require any form of medical treatment.
Individuals suffering from cardio vascular diseases and heart conditions will often experience symptoms of hypotension. This is primarily due to the fact that their hearts are weaker than those of healthy individuals and thus are not able to pump blood as forcefully through the arteries. Diseases such as blood poisoning, kidney infections, haemophilia and toxic shock syndrome are also common causes of low blood pressure.
Certain medications and drugs have the effect of substantially lowering blood pressure. Heart medicines and diuretics have been known to cause hypotension, as have various high blood pressure medications. Anti- depressants, medicine used in surgical procedures and alcohol are also recognised triggers of low blood pressure.
Low blood pressure can also be caused by other more common conditions such as everyday infections, blood loss, stress, extended bed rest, and pregnancy. Generally, low blood pressure is viewed by medical practitioners as being far healthier than high blood pressure due to the fact that it places far less strain on the arteries and heart. When blood pressure drops too low however, it can result in unpleasant side effects and even become life threatening. It is therefore essential that individuals suffering from even slight hypotension ensure that they adopt a healthy lifestyle and have their blood pressure checked on a regular basis.
