111\/38 mmHg has a systolic (top) pressure of 111 and a diastolic (bottom) pressure of 38. The bottom number is low. This result needs a different interpretation from an ordinary normal reading, even though the top number is above 90. A single measurement does not establish a diagnosis or explain the cause.<\/p>\n\n\n\n
This page uses the term isolated diastolic hypotension for the numeric pattern of diastolic pressure below 60 with systolic pressure at least 100. The 2011 Guichard study<\/a> used this definition in adults aged 65 and older. Its findings do not establish a diagnosis or predict an individual outcome from this one reading.<\/p>\n\n\n\n Dizziness, fainting, blurred vision or unusual weakness may accompany low pressure. Some people have no symptoms. Symptoms alone do not identify the cause, and feeling well does not verify that the monitor reading is accurate.<\/p>\n\n\n\n Call your local emergency number if there are signs of shock, such as cold, clammy skin, rapid breathing or a weak, rapid pulse. Severe chest pain, trouble breathing or loss of consciousness also require urgent medical help. Do not delay care to keep taking measurements.<\/p>\n\n\n\n Low readings can occur with dehydration, blood loss, some medicines or underlying heart or hormonal problems. These are possibilities for clinical assessment, not conclusions that can be drawn from these two numbers. The American Heart Association describes causes and symptoms of low pressure<\/a>.<\/p>\n\n\n\n Record whether the result followed illness, a medication dose, a meal or standing up. Also note your pulse and any symptoms. Bring the record and your monitor to a healthcare appointment if the low results continue.<\/p>\n\n\n\n Pulse pressure is the difference between the top and bottom numbers. A mean arterial pressure (MAP) estimate combines both numbers using a formula. Any calculated value on this page is derived from the entered reading and inherits its measurement errors.<\/p>\n\n\n\n These estimates cannot establish that blood flow is adequate, identify arterial stiffness or diagnose shock. Interpret the original measurements, symptoms and medical history with a clinician rather than using a calculated value as permission to ignore symptoms.<\/p>\n\n\n\n If you feel faint, sit down safely and seek help if symptoms persist or worsen. Repeat the measurement when it is safe to do so. A clinician can decide whether the repeated low bottom number needs further assessment.<\/p>\n\n\n\n Use a validated upper-arm monitor with a cuff that fits. Rest quietly for five minutes, then measure with your arm supported at heart level and the cuff on bare skin. Avoid smoking, caffeine and exercise for 30 minutes beforehand. Take two readings one minute apart and record both, following the American Heart Association home measurement instructions<\/a>.<\/p>\n\n\n\n A repeated low diastolic value deserves clinical context, particularly in someone who already has cardiovascular disease or takes blood pressure medicines. Research associations in older adults cannot tell you the cause, urgency or long-term risk of this isolated result.<\/p>\n\n\n\n If the numbers repeatedly look unusual, have a healthcare professional check your technique, cuff and monitor. Use our blood pressure measurement guide<\/a> to prepare for that discussion.<\/p>\n\n\n\n Management depends on the cause and symptoms. A clinician may review medicines, hydration, illness and other health conditions before deciding whether treatment is needed. Do not stop prescribed medicine or change its dose because of this page.<\/p>\n\n\n\n There is no universal salt, fluid or medication prescription for a reading of 111\/38. Extra salt or fluid may be inappropriate for people with heart or kidney conditions. Ask for advice suited to your medical history. If pregnant, discuss unexpected low readings or symptoms with your maternity care team.<\/p>\n\n\n\n For an overview, read our guide to low blood pressure<\/a> and NHLBI guidance on symptoms, assessment and treatment<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":" 111\/38 mmHg has a low bottom number of 38.
