Blood pressure is the force that the blood applies on the inner walls of the artery. Normal pressure in a healthy person would read 120/80. When the pressure falls below 90/60, the condition is referred to as low blood pressure or hypotension. While low pressure is indicative of some underlying health problem, it might appear in otherwise healthy people also.
While some reasons for low pressure are harmless, others can be due to health complications. A heart disease such as low rate of the heart, problems with the valves, or failure of the heart causes low pressure. Thyroid disorders, a disease in the liver, over dosage of medicines for hypertension, low levels of blood sugar, deficiency of nutrients, side effects of certain medication, or allergy also cause fall in blood pressure. In the initial six months of pregnancy, women experience low blood pressure because of expansion of the blood circulation system. Children experience this condition for a while when they exert themselves by standing for long periods of time, have loss of blood or also as a result of dehydration.
Symptoms of low pressure
Dizziness, faintness or lightheartedness
Severe conditions show the state of confusion, a lapse in concentration, or spells of unconsciousness. Continued low blood pressure can result in depression. Such patients also complain of vision getting blur, tiredness, nausea or skin becoming clammy and cold.
Low pressure affects the heart and lungs
The former manifests as pain in the chest, or angina. While the later causes breathing difficulty, or shallow or rapid breathing If any symptom persists along with headaches, unconsciousness or trouble in speech, immediate treatment is a must.
Low blood pressure may sometimes also result in fatigue, weakness, and even depression
However, this has not been proven. Research, however, does indicate that individuals having a steady low blood pressure tend to weigh less and be short in stature compared to those with an average reading. These individuals don’t necessarily suffer from weakness or fatigue.Often, chronic fatigue sufferers are misdiagnosed with low blood pressure, as symptoms are the same. Some instances of low blood pressure may be observed during the day as pressure fluctuates according to activity. These low systolic and diastolic readings cannot be considered as low blood pressure. It is only when there is a steady low reading for a particular period that the individual may be diagnosed with low blood pressure
Doctors and other medical practitioners continue to argue about low blood pressure symptoms and whether they exist or not. There are those who say it is all down to the chance association and that there is no connection between cause and effect.
