If medically represented, low blood pressure refers to hypotension. It refers to the blood pressure that is below normal or required range. It weakens the action of the heart forcing the blood through the arteries. Some general symptoms include dizziness, weakness, fatigue, light headedness and lethargy. A routine medical check-up and identified examination is essential to avoid the case from worsening.
In many cases, hypotension gets better without any treatment. Various reasons including, reduced cardiac output, abnormal heart rhythms, pulmonary embolism, weakened heart muscles, reduced blood volume, excessive dilation of the blood vessels, exposure to heat etc are highly responsible for lowering the blood pressure from normal.
Other specific diseases that are associated with low blood pressure include fainting, hypoaldosteronism (deficiency of the steroid hormone that is generated by the adrenal glands). Apart from this hypotension can be caused by intake of certain medications like antidepressants, diuretics, nitrates and calcium channel blockers. Untreated diabetes and spinal cord injuries may result in hypotension that damages the regulation of the blood vessels.
Low blood pressure may not require treatment, again it depends on the severity. Pregnant women have got greater risks of developing low blood pressure levels.
