Stroke is the third-leading cause of death after heart disease and cancer. A stroke occurs when blood to the brain is deprived for a period of time or when vital signs are temporarily impaired. The consequences of a stroke depend on the severity of the stroke: left untreated, it leads to paralysis (paralysis can be temporary or permanent) and death. Untreated, stroke may lead to permanent damage in the brain. This is why stroke is often called a silent killer.
There are many factors that make stroke risks higher in some people than in others. Stroke risk factors vary with the type of stroke (the result of a blood clot in arteries supplying the brain tissue), with the timing of onset, and with the extent of the injury. Although some diseases such as diabetes have no relationship with stroke risks, hypertension and other conditions may be a risk factor in combination with other risk factors.
Some diseases that increase stroke risks are family history of stroke, higher risk of suffering from ischemic strokes, and family history of heart disease. It has also been found that the risk increases greatly if one or both legs are disabled thuc pham chong dot quy. Other risk factors include: obesity (especially for women), diuretic abuse (including alcohol consumption), estrogen therapy, cigarette smoking, use of tobacco, high blood pressure, sedentary lifestyle, diabetes, and previous cardiovascular or kidney disease. Some studies have revealed that men who smoke have a 50% higher risk of suffering a stroke.
The family history of ischemic strokes can be an important determinant of stroke risks, especially in families where both members have had ischemic strokes. People who have other family members who have had ischemic strokes are also at greater risk. In addition, people who have experienced a family history of heart disease are at a higher risk of suffering a stroke.
The increased risk of stroke risks seems to be exacerbated by the fact that a high percentage of the population today consumes diets which are primarily saturated fats from animal sources. It is important to reduce consumption of foods that are high in saturated fat in order to reduce the stroke risks. Some of these include red meat, organ meats, butter, dairy products, cream, some fats derived from fish, sugar, potatoes, dried fruits, peanuts, refined vegetable oils, fried fatty foods and other foods that contain saturated fat.
Diabetes and birth control pills seem to increase the risk of stroke even more. Diabetes mellitus, which is a disease of the insulin-sensitive tissues, may be the underlying factor of some types of strokes. Birth control pills are hormonal contraceptives that prevent ovulation. They also reduce levels of testosterone, which can contribute to conditions like diabetes. However, some doctors believe that more studies are needed to investigate the possible link between diabetes and strokes.
