• Noise in the ears
• Cloudy sight
• Frequent hemorrhages in the nose and eyes

Nevertheless, high blood pressure may exist without symptoms, that is the reason why it has been given the name of "The Silent Killer"

Causes : There are many causes of physical  as well as psychological origin.

The ones of physical origin are in general due to the presence of atherosclerosis or arteriosclerosis or kidney problems (infection), as well as the obstruction of an artery.

Other associated causes are : Heredity, obesity, the intake of too much salt (since sodium causes a retention of liquids), smoking, drinking wine, coffee or tea in excess, and contraceptives.

The ones of psychological origin are accompanied by current anguish, nervousness and emotional imbalances.

Stress or tension causes the veins to contract, becoming smaller. This provokes an increase in pressure (this is the reason why we become pale when we are scared). The type of people with a high stress level should make a change in their way of life, eliminate worries and nervousness, change their nutrition, and exercise daily.
