How long after a meal should I measure my blood pressure

People with high blood pressure and low blood pressure must always have a blood pressure monitor so that they can know their blood pressure at any time. Some people like to measure their blood pressure after getting up in the morning, while others are used to measuring it after meals, but how long after a meal is normal to measure blood pressure? We know that blood pressure is more easily affected by other factors, such as emotions, exercise, mood, etc. Therefore, if you want to measure a normal blood pressure, you should measure it when the body is quiet, preferably two hours after a meal.

When should blood pressure be measured?

Frequency of blood pressure measurement: Measuring blood pressure is one of the necessary prenatal examination items. Under normal circumstances, blood pressure is measured once in the early stages of pregnancy (3 months of pregnancy), and this value is used as the baseline blood pressure during pregnancy, and is checked regularly during subsequent prenatal examinations. The ideal number of prenatal checkups during the entire pregnancy is 9-13 times, that is, the ideal situation is to measure blood pressure 9-13 times during the entire pregnancy.

Precautions for blood pressure measurement: Blood pressure measurement is easily affected by the expectant mother's own emotions, exercise, psychological state and other factors. Therefore, it is necessary to measure when the mind and body are in a quiet state. Otherwise, the data will be distorted and have no reference value.

1. Expectant mothers should relax their body and mind: they must be in a quiet state when measuring blood pressure, and avoid measuring blood pressure under stressful conditions such as with a full bladder or after smoking, catching a cold, or drinking coffee.

If the expectant mother has just done some light activities before the measurement, she should rest for 10-15 minutes and measure her blood pressure after she calms down. Otherwise, measuring blood pressure immediately will result in an artificially high blood pressure reading.

2. Avoid eating: It is best not to eat within half an hour before blood pressure measurement, as this may affect the accuracy of the measurement.

3. Don’t hold your breath: Don’t be nervous when measuring your blood pressure and don’t hold your breath, because holding your breath can increase your blood pressure.

Normal range of blood pressure

The normal blood pressure range for pregnant women is: not exceeding (130/90 mmHg), or not exceeding (30/15 mmHg) compared with the baseline blood pressure.

The current blood pressure judgment standards in my country are:

Category Systolic blood pressure (mmHg) Diastolic blood pressure (mmHg) Remarks

Ideal blood pressure <120 <80

Normal blood pressure <130 <85

The normal high value is 120-13980-89, and only one of the data needs to be met.

Hypertension ≥140≥90 only needs to meet one of the following criteria to be diagnosed as hypertension.

However, there is no uniform standard for the diagnosis of hypotension. Generally speaking, hypotension is an upper limb arterial blood pressure of less than 90/60 mmHg in adults.

How to read blood pressure values? For example, 120/70 mmHg. The number 120 in front is the systolic pressure, which refers to the pressure exerted by the blood on the large blood vessels when the heart contracts and supplies blood to our body. The number 70 at the end is the diastolic pressure, which refers to the pressure in the blood vessels when the heart stops contracting.

Unit description: Blood pressure is usually measured in millimeters of mercury (mmHg). 1 mmHg is equal to 133.3224 Pa (Pa).
