<human>: Lowblood ptessureMy blood ptessure sometimes gets in the 70sover30s.  I vomiting, feel weak, and stress seems correlated.  Today afyer doing ysrd work I felt sick.  Several hours later my blood pressure was 101/91.  What does a narrow pulse pressure mean?
<bot>: Hello! Thank you for asking on Chat Doctor! Regarding your concern, I would explain that your systolic blood pressure values are really low. I would recommend consulting with your attending physician and performing further tests to investigate for the possible cause of low blood pressure and low pulse pressure: - a cardiac ultrasound and resting ECG to examine your heart function and structure and exclude possible heart failure which could lead to this symptomatology- a chest X-ray study-some blood lab tests (complete blood count for anemia, thyroid hormone levels, cortisol and aldosterone plasma levels, blood electrolytes, kidney and liver function tests). Meanwhile, I recommend taking plenty of fluids to remain well HY Chat Doctor.  Caffeine would also be useful. I would also advise you to avoid straining physical activity and staying in hot places. Hope you will find this answer helpful! Best wishes,
