Gastrointestinal problems and nausea are among the problems that can lead to consumption of certain vitamins in tablets.

Because every day people think more of the benefit that has vitamins in our physical, mental and physiological, consumption of vitamin supplements in tablets each day has increased in the last decade. However, high consumption has been overlooked that they can cause toxicity, although the absorption is lower than those from natural sources.

This problem occurs mainly in the case of lip soluble vitamins A, D, E, K and which by its chemical nature are more difficult to remove and deposit in the tissues.

Vitamin D and E are the market leaders, the first for its importance in calcium metabolism and therefore in the prevention and treatment of osteopenia and osteoporosis. In the case of vitamin E by its antioxidant property, its protective effect against oxidative damage at the cellular level, arterial vasodilators, regularization of the flow and for preventing thrombus formation, reduces the risk of developing myocardial infarction.

Necrosis confined to a more or less tissue myocardial ischemia resulting from a sudden coronary artery. During a myocardial infarction, irrigation is no longer; deprived of blood and oxygen, the myocardial cells suffer and die, releasing their cardiac enzymes, with destruction of surrounding tissue. Men are affected twice as often as women. Myocardial infarction is one of the most common causes of death.
Today, the very definition of myocardial infarction tends to disappear in favor of acute coronary syndrome ST more versus acute coronary syndrome not included ST.

Causes:
The occlusion of one or more coronary arteries is almost always due to the formation of a thrombus (clot) on a plaque consisting of cholesterol deposits against the inner arterial wall. This condition occurs most often in patients with risk factors such as smoking, hypertension, high cholesterol, diabetes, sedentary lifestyle.

Symptoms
In half the cases, infarction occurs after a period shorter or longer during which the subject suffers from angina.
The pain (tightness, burning, sometimes crushing) are felt behind the breastbone (retrosternal), and can radiate to the left arm to the jaw, sometimes in the back. They disappear in a few minutes rest, sometimes with the use of a spray nitro.
In the other half of the cases, stroke is opening, that is to say that there are no warning signs. It manifests itself by severe pain sharp retro sternal (such as angina but longer and more intense). The pain may radiate to the arm, jaw and back. It is often constrictive and accompanied by anxiety and feeling of impending death. (more…)
