Low Blood Pressure
Low blood pressure accompanies chest discomfort as an indication of MCAS or mast cell activation in the heart. There is no clear trigger for this, but many patients complain about rapid heart rates and low blood pressure.
Low blood pressure or hypotension occurs when the blood pressure is lower than 90 mm of mercury (mm Hg) for the systolic or top number or 60 mm Hg for diastolic or bottom number. Low blood pressure may be dangerous and life-threatening, but it does not appear with symptoms for everyone. Some may report fainting and dizziness, while others do not feel anything at all.
Low blood pressure may be caused by simple dehydration to other medical conditions like MCAS. The patient should determine what is causing their low abnormal blood pressure levels, with the help of a medical professional, to treat it properly. Otherwise, it could lead to severe heart and brain damage complications, which occur when the body suffers from extremely low oxygen levels.
