Low blood pressure ranges are much more difficult to quantify even if the current guidelines state that the normal range is 120/80. However, some health care experts identify low blood pressure ranges as values that are way lower than ninety systolic pressure and sixty diastolic pressure. Similarly, a blood pressure reading that has one lower number either in systolic or diastolic pressure can be considered as low blood pressure. Even if the systolic pressure is 120 (normal) but the diastolic pressure is fifty, this can be considered as hypo tension.
Detecting the symptom is difficult until it is too late. But most of the time, common signs include light headedness, dizziness, and fainting. The lowest category of hypo tension is when the pressure significantly drops to a much lower level that is way below the normal range. A systolic pressure that is below sixty coupled with a diastolic pressure of below forty is a very low blood pressure which can expose the person to various risks associated with chronic hypo tension. Dangerous low ranges have readings of 50/33 and this is common to those suffering from atherosclerosis, arteriosclerosis, kidney problems and other related illnesses. A sudden drop in blood pressure can be very dangerous. A sudden change of 20 systolic pressure from 130 to 110 can result to fainting and dizziness. This happens because the brain is not able to get enough supply of oxygen and other nutrients usually carried by the blood. When this happens other related ailments may occur such as stroke, hardening of arteries, and visual damage among others.
Causes Of Low Blood Pressure
The sudden drop of pressure ranges from the chart can be attributed to a lot of factors. For example, your level can significantly drop due to shock. Severe dehydration often results to hypovolemic shock which is also a life threatening condition. Other types of shock that cause the blood pressure to drop is anaphylaxis. This is an allergic reaction due to insect bites, food allergies, and a septic shock when an infection is integrated with your blood stream.
Medications can also drop the level of your pressure. Drugs used for treating high blood pressure (diuretics) can cause your blood to lose pressure. According to the American Heart Association, majority of heart medications like antidepressants and beta blockers as well as the drugs used for treating Parkinson's can significantly drop the levels of blood pressure. Using narcotics and overconsumption of alcohol can also drop it as well as other over the counter drugs that can interact with hypertension medications. You can also suffer because of other underlying conditions such as low blood sugar, thyroid problems, and heart failure. Pulmonary embolism and Addison's disease can also result to a lower blood pressure level.
Risk Factor And Complications
Hypo tension or can easily happen to anyone although there are several types of hypo tension that are common based on your age and other relevant factors. For example, the drop in blood pressure when standing suddenly or after eating a meal usually happens to adults with ages sixty five and above. The drop in blood pressure when suddenly standing up is known as orthostatic hypo tension. The drop that occurs after eating a meal is also known as postprandial hypo tension. Neurally mediated hypo tension on the other hand occurs due to the miscommunication between the heart and the brain. This type of hypo tension is more common among younger adults and children. Even the moderate types of hypo tension or low pressure can not only cause light headedness and dizziness but also fainting. Chronic low blood pressure from any cause of hypo tension can deprive your system with ample amounts of oxygen that will impede it from performing its normal functions. This can lead to brain or heart damage which further increases the risk for fatality.
