What does it mean if you have low blood pressure?

Another name for low blood pressure is hypotension.
Blood pressure is a measure of how hard the blood pushes against the walls of your arteries as it moves through your body.
Within certain limits, the lower your blood pressure reading is, the better. There is also no specific number at which blood pressure is considered too low, as long as none of the symptoms of trouble are present.

Nothing will delay it, but drinking some lemon (squeeze 3) would cut it, making it last a few days, but its not good to do that. won't hurt you but the next month will be more cramps.. take some advils with you on the trip
