Some causes of secondary hypertension

About 90% of hypertensive patients, no known cause and circumstances are referred to as essential hypertension or primary hypertension. Essential hypertension is likely to have many causes, some changes on the heart and blood vessels may contribute to increased blood pressure.

If the cause is unknown, it is called secondary hypertension. In about 5-10% of patients with hypertension, the cause is kidney disease. And about 1-2%, the cause is a hormonal disorder or the use of certain drugs (such as birth control pills). Another rare cause of hypertension is Phaeochromocytoma, namely tumor on the adrenal gland that produces hormones epinephrine (adrenaline) or norepinephrine (noradrenaline).

Overweight (obesity), an inactive lifestyle (exercise lazy), stress, alcohol or salt in food, can trigger the occurrence of hypertension in people who have a sensitivity derivative. Stress tends to cause increased blood pressure for a while, if the stress has passed, then the blood pressure usually returns to normal.

The majority of people with moderate to severe blood pressure could not say when their blood pressure becomes high. In fact, about a third of people with hypertension are unaware of their circumstances. If symptoms begin to appear, the patient may experience chest pain (angina), shortness of breath or other symptoms associated with heart disease or damage to the underlying.

In most people with hypertension do not cause symptoms, even if by accident some of the symptoms can appear simultaneously and reliably associated with high blood pressure (hypertension).

Symptoms are:
Headache
Bleeding from the nose
Dizziness
Facial redness and fatigue
But that does not mean someone with the symptoms above certainly suffer from high blood pressure (hypertension), because the symptoms above are not only can occur in patients with hypertension, but also can occur in people with normal blood pressure.

If severe or chronic hypertension and untreated, can develop the following symptoms:
Headache

Throw up
Blown
