Does fasting affect blood pressure measurements?
Measuring blood pressure is a commonly used method of examination, especially for patients with hypertension. Regular monitoring of blood pressure helps prevent diseases. When taking blood pressure measurements, it is important to understand some precautions. Generally, it is possible to measure blood pressure on an empty stomach, which will not have a negative impact on the results. However, it is recommended to avoid measuring blood pressure when one is overly emotional, and to pay attention to the proper techniques to avoid affecting the results.
As long as the method of measuring blood pressure is correct and the blood pressure monitor is functioning properly, the blood pressure measured on an empty stomach will be accurate. Generally, being on an empty stomach does not affect blood pressure measurements. Unlike other biochemical indicators, blood pressure can be measured at any time, but the measurement method must be correct. For instance, the indoor temperature should be appropriate and the environment should be quiet. Additionally, the person being measured should rest for 10 minutes before taking the measurement.
Step 1: Stabilize Emotions: Blood pressure fluctuates depending on a person's emotions and physical activity. To obtain accurate blood pressure readings, it is important to calm the person being measured and allow them to rest for several minutes before taking the measurement.
Step 2: Attention to Measurement Technique: When measuring, the person should be seated rather than standing. Their arm should be kept parallel to their heart, and the blood pressure monitor should be positioned at the same level as their elbow and heart.
Step 3: Start Measuring: In hospitals, cuff-type blood pressure monitors are commonly used as they provide accurate readings. When starting the measurement, the cuff should not be too tight or too loose to prevent inaccurate results. After the pulse disappears, the measurer should add 30 mmHg and then begin deflating the cuff.
