Normal blood pressure standards are obtained from measurements taken by the body at rest. Generally speaking, a systolic blood pressure of 90-120 mmHg and a diastolic blood pressure of 60-80 mmHg in a 40-year-old woman can be called normal blood pressure. A systolic blood pressure of 120-139 mmHg and a diastolic blood pressure of 80-89 mmHg can be called high normal blood pressure and is still within the normal range. For 40-year-old women, belonging to the menopause, blood pressure values will occasionally fluctuate due to emotional or external causes, generally have little effect. In daily life, you can buy a blood pressure meter to self-measure and pay attention to the blood pressure index in time. Eat a reasonable diet, eat less food high in oil and salt, it is generally recommended that the daily intake of salt should not exceed 6g. Obese people should control their diet and exercise reasonably, while maintaining a good state of mind and avoiding mood swings in order to control blood pressure within the normal range. If the blood pressure is measured on different days in a row and the systolic pressure is >140mmHg and diastolic pressure is >90mmHg, the possibility of hypertension is considered and should be taken seriously. If a woman has a family history of inherited hypertension, she has a higher chance of developing hypertension and should monitor her blood pressure at any time with regular measurements. Or those who often smoke, drink alcohol, stay up late, are stressed, and rarely exercise are also the people who are prone to hypertension. Usually hypertension can be treated by taking antihypertensive drugs, such as diuretics, calcium antagonists, angiotensin-converting enzyme inhibitors and other common drugs, which need to be selected according to medical advice. Some women in their 40s who are weak or suffering from chronic wasting diseases may have hypotension, i.e. systolic blood pressure <90mmHg and diastolic blood pressure <60mmHg. They may experience dizziness, blurred vision, nausea and other symptoms, so they need to pay attention to strengthening nutrition and applying medication as prescribed by the doctor.
