Whether or not a blood pressure reading of 140/70 requires medication depends on a variety of factors. Blood pressure readings are typically categorized as normal, pre-hypertension, and high. A reading of 140/70 is considered pre-hypertensive, meaning that it is slightly higher than the ideal reading of 120/80.
In general, someone with a pre-hypertensive reading may not require medication. However, if a person is consistently experiencing pre-hypertensive readings, they should talk to their doctor about lifestyle changes that may help to reduce their blood pressure. This could include eating a healthier diet, exercising regularly, and reducing stress. It is also important for individuals to keep track of their blood pressure readings, so they can monitor any changes.
In some cases, a doctor may recommend medication even with pre-hypertensive readings. This could be the case if a person is at risk for developing hypertension or if they have other health conditions that put them at risk of complications from high blood pressure. For example, a doctor may recommend medication if a patient has diabetes, heart disease, or kidney disease.
Overall, whether or not a blood pressure reading of 140/70 requires medication depends on the individual's health and risk factors. It is important for individuals to talk to their doctor about their blood pressure readings and their options for managing them.
