Primary hypotension can be treated with physical measures very well, although secondary hypotension, e.g. resulting from inadequate cardiac performance, must be excluded as a cause. The unpleasant symptoms of hypotension, such as general weakness and apathy, fatigue and dizziness, especially when changing body position and with high ambient temperatures, are caused by an inefficient distribution of blood that is normally available in sufficient amounts. The inadequate venous tone leads to blood accumulation in the legs and the pelvic and gastric areas. The systolic blood pressure falls and the diastolic pressure increases. Brain perfusion is reduced so that the above mentioned symptoms occur.
