What are the consequences of sodium intake with high blood pressure? I heard someone asking this question that is why I am asking you guys. Have any of you faced any problems with sodium when you have high blood pressure. My uncle has HBP and I want to tell him what he should and should not be having. What sodium present is in and how much is safe to take in. Can it be completely prevented? What are the side effects of having sodium when you have high BP. Does it cause long term problems?
