Orthostatic hypotension is the abrupt pressure drop , sometimes up to critical level . The phenomenon develops both as inveterate , and in ordinary , quite healthy the great unwashed under certain precondition ( protract stress , being in one stead without movement , sleep , etc . ) .
The mechanics of development of orthostatic hypotension lie in a sharp outpouring of line from the mental capacity and intellectual bodily structure when rise from a lying or sitting position . This is possible due to hemodynamic disruption in various pathology , both cardiac and extracardiac origin ( orthostasis is the vertical position of the organic structure ) .
Frequent culprits are heart failure , metabolic and lipid metabolism disorders , a want of hypertensive message in the torso with adrenal disease , etc .
The disease rarely provokes health and life - imperil outcome , but a similar scenario is potential . Therefore , neglecting handling , hope that the pathology itself will recede , is not worth it.(1 )
What Neurological Problems Cause Orthostatic Hypotension?
Patients with heart valve disease , gist failure , and heart attack may experience orthostatic hypotension . However , certainneurological disorderscan also make this status . Examples includeamyloidosis , Parkinson ’s disease , Shy - Drager syndrome ( or multiple system atrophy ) and other unvoluntary neurological disorders . These precondition hamper proper blood stream through the blood vessels precede to orthostatic hypotension .
The neurological form occurs in almost 60 % of cases , which makes it the main causal agency in the frequency of clinical situation . It is cause by neurocirculatory upset due to a modification in the nature of the work of the sympathetic and parasympathetic nervous system . The mechanisms are sometimes so complex that it is impossible to understand.(2 )
Is Orthostatic Hypotension A Disability?
Orthostatic hypotension may get severe disability , and patient experience giddiness , vertigo , fainting , and other problem that can have a unfathomed negative impact on daily life sentence that ask stand or walking .
If the symptoms of this upset severely strike your power to work , you may be eligible for social security disability benefit . Autonomic nervous disorder describe any disease that touch on the autonomic nervous system.(3)(4 )
Factors Causing Orthostatic Hypotension
Malnutrition : The deficiency of B vitamin affects the shape of the spirit and rip vessels , as well as the composition and quantitative and qualitative characteristics of the parentage . Most often , malnutrition and nutritional factors are mostly institute in young women who supervise their appearance . force factor are also possible : for certain societal reasons . Anorexia all the more direct to this consequence .
Varicose Veins Of The Lower Extremities : At first glimpse , it seems strange but everything is within the theoretical account of logic . As a outcome of varicose nervure of the lower extremities , blood stagnancy occurs . The loudness of circulating hematological fluid remains the same , but not all blood is involved in the hemodynamic process . Hence the decrease in line pressure sensation until the process normalizes .
Neuropathies Of Various Etiologies : include hepaticencephalopathy , deflower neurocirculatory role , etc . the reasons for orthostatic hypotension , in this case , lie in the violation of the regulating of vascular whole tone at the highest grade : the “ orders ” are give by the nervous organization , which is not at all in ripe condition to command . like phenomena occur in diabetes and hypothyroidism .
Brain tumor Of Various Types And Localizations : particularly often expressed misdemeanour of the regulation of blood force per unit area givegliomasof the brain stem , germinomas , big pituitary adenomas that constrict on the hypothalamus and others . A mass effect is created : neoplasia artificially stimulates brainiac tissue paper to give false signal , sometimes chaotic .
Another Significant Reason Is Cardiac Pathologies : Including inborn and acquired malformations of the organ , heart unsuccessful person , disease relate with myocardial lighting .
infective pathology : Here we are talking not only and not so much about common colds , but about severe pathologies of bacterial and viral pedigree , for example , about continuing tuberculosis . The torso gives all its energy to fight down infection . Also , the incursion of toxins farm bymycobacteriainto the structure of the brain pass . Hence the false stimulation of the hypothalamus and limited centers that cause an induced reduction in line pressure .
Thromboembolism : At the first moment , it is accompanied by arterial hypotension . It afterward cease with acute tissue ischemia and death in a little time .
Violations Of The Endocrine Profile : This also bear on the change in the nature of the work of the adrenal cortex ( Addison ’s disease , etc . ) , insufficient synthesis of specific substances of the thyroid gland gland ( hypothyroidism ) . This is the 2nd most common cause of orthostatic hypotension in people of all ages and grammatical gender .
The reasons can be not only pathological but also quite natural . They do not involve therapy , except in rarified cases : maternity , change of life , adolescence , protracted bed ease , lack of physical activity.(5 )
