Experts urge people to remain aware of as many potential warning signs of life threatening conditions as possible.
That includes the lesser-known sign, as spotting a rare or unusual symptom and flagging it to your GP could lead to early detection. An example of this may be bloodshot eyes, which can be a sign of high blood pressure, or hypertension.
The condition puts added stress on your blood vessels and vital organs, forcing your heart to work harder and increasing the risk of heart attacks and strokes, writes the Mirror.
