<s>[INST] I have typically had an average blood pressure of about 120 over 68-70. In the last week I have felt very faint and was very white in the face. I took my blood pressure and it was 80 over 44 on Sunday. Yesterday, Wednesday, it was higher - I think 90 over 45. I have never had low blood pressure like this and I just don t feel good. I have no idea what would cause my blood pressure to dip like this. What are some causes of low blood pressure? Are the latter ratios too low? Thanks:) [/INST] Hi, After going through your medical query I understand your concern and I would like to tell you that most likely insufficient diet or nutritional deficiencies and less liquid intake can be common cause of low blood pressure. It's recommended for you to take plenty of liquid intake with extra salt in diet .if it doesn't help then kindly a physician for proper evaluation and treatment.  Hope I have answered your query. Let me know if I can assist you further.  </s>
