<s>[INST] Female 71 , 106 kilos. Blood pressure goes from normal to high then can drop very low . My heart rate slows down and I break out into sweats when I walk or do any house work. I become very ill in stomach when this happens and get dizzy and have to lie down . [/INST] Hello! Thank you for asking on Chat Doctor!  Regarding your concern it is necessary to perform a thorough monitoring of your vital parameters (especially blood pressure and heart rate and rhythm). Only after matching your clinical symptoms with possible corresponding BP and heart beating abnormal fluctuation, could be possible to follow the appropriate treatment strategy. I recommend performing an ambulatory 24 to 48 hours ECG monitoring coupled with very frequently BP measurements (even a BP ambulatory monitoring would be advisable). Some lab blood tests are also recommended (including complete blood count, fasting glucose, thyroid hormones, liver and renal function tests, etc). I recommend contacting your doctor (GP or internist) to build up a scheduled strategy of management that issue. Greetings!  </s>
