Low Blood Pressure

Steven seemed very tired and lethargic today, this often is the case the day after he has seen Miles. 

There is also concern that his blood pressure is low

Hypotension is the medical term for low blood pressure (less than 90/60 mm/Hg).

A blood pressure reading appears as two numbers. The first and higher of the two is a measure of systolic pressure, or the pressure in the arteries when the heart beats and fills them with blood. The second number measures diastolic pressure, or the pressure in the arteries when the heart rests between beats.

Normal blood pressure is usually in the range of 120/80 mmHg (systolic/diastolic). In healthy people, especially athletes, low blood pressure is a sign of good cardiovascular (heart and blood vessel) health. But low blood pressure can be a sign of an underlying problem - especially in elderly people - where it may cause inadequate blood flow to the heart, brain and other vital organs
