What causes weakness and tiredness when having bouts of low blood pressure?
Patient: I have been having bouts of low blood pressure ranging from high 90's to low 90's over high fifties to lower fifties. I AM A 53 Year old female who does smoke.  I have noticed that I feel very tired and weak when my pressure is this low. Thank you for any feedback that you may be able to provide. Doctor: hiyou should get a 2d echo done as soon as possibleheart has to pump a definite amount of blood to maintain the normal blood pressure but if the wall of the heart gets week as age progresses the left ventricular ejection fraction of the heart also drops down hence blood pressure can not be maintainedsecondly get your serum electrolytes check less sodium can also cause low b.pthanks
