Which of the following is NOT a common cause of hypertension?

Low sodium intake is recognized as a factor that can actually help reduce blood pressure, rather than contribute to hypertension. In contrast, factors such as obesity, stress, and tobacco use are commonly associated with an increase in blood pressure. Obesity is linked to higher blood volume and resistance in blood vessels, leading to hypertension. Stress can cause temporary spikes in blood pressure, and chronic stress may have long-term effects that contribute to hypertension. Tobacco use damages blood vessels and can result in elevated blood pressure. Thus, among the options provided, low sodium intake stands out as not being a common cause of hypertension.
