Should I take medication for high blood pressure with a systolic reading of 145 mmHg and diastolic reading of 90 mmHg?

 　Whether medication is needed for a blood pressure reading of 145 mmHg systolic and 90 mmHg diastolic depends on individual circumstances. Typically, medication is not required if there are no accompanying symptoms; however, if clinical symptoms are present, treatment with medication may be necessary. The detailed analysis is as follows:
　　1. Medication not required
　The normal blood pressure range is defined as systolic pressure between 90 mmHg and 140 mmHg and diastolic pressure between 60 mmHg and 90 mmHg. Various factors can cause temporary increases in blood pressure, such as intense physical activity or dietary influences. If elevated blood pressure results from exercise or diet, drug therapy is generally unnecessary. Adjusting exercise routines and modifying dietary habits can often alleviate the condition. For example, adopt a light diet and avoid foods such as pickled vegetables and fried chicken. Additionally, manage emotional well-being by avoiding stress and excitement, and maintain a regular sleep schedule.
　　2. Medication required
　If abnormal blood pressure is caused by an underlying disease and is accompanied by symptoms such as headache, dizziness, or general weakness, drug treatment under a physician's guidance is necessary. Without proper treatment, persistently high blood pressure may lead to various complications and could even be life-threatening. Antihypertensive medications such as spironolactone tablets or benazepril hydrochloride tablets may be prescribed.
　If antihypertensive drugs are required to control blood pressure, it is essential to consult a doctor beforehand and strictly follow medical instructions to prevent adverse effects such as hypotension due to improper medication use.
