ALL YOU NEED TO KNOW ABOUT MALE HEALTH...
| Chronically elevated blood pressure is a risk factor for heart attack, heart failure, and stroke, and is one of the most prevalent causes of kidney failure. In most cases, treating high blood pressure begins with a series of lifestyle changes such as diet modification and increased exercise. Such lifestyle changes are not always successful, however, and in these cases medication may be added to the treatment regime. Answering the question of how to treat high blood pressure is a highly individual matter which partially depends on the cause of the condition. High blood pressure can be caused by medical conditions such as kidney cancer or other types of kidney disease, but up to 95% of cases of high blood pressure have no specific medical cause. In most cases, therefore, lowering high blood pressure is the goal of treatment. In those cases where there is an underlying medical cause of high blood pressure, medical intervention may be aimed at treating the cause, rather than the high blood pressure itself. Another consideration is the individual’s current lifestyle. For some people, the best way to treat high blood pressure is with a combination of lifestyle changes such as diet and exercise. | |
| This is not always the most effective method, however. Someone who already gets plenty of exercise and has a healthy diet will probably get more of a benefit out of medication. For an individual who has high blood pressure with no underlying medical cause, there are several options for treatment. Before medication is tried, most doctors will attempt to treat high blood pressure with lifestyle changes. Often, the initial recommendation is cardiovascular exercise such as walking or running, perhaps accompanied by a weight loss diet. Adoption of a diet high in foods to treat high blood pressure, such as high-fiber vegetables, legumes, and grains, as well as a reduction in salt and excess alcohol, can have some benefit. The typical diet suggested is called Dietary Approaches to Stop Hypertension, or the DASH diet. This diet includes plenty of fresh vegetables and fruit, as well as low-fat dairy products, and reduced sodium. When dietary changes and exercise do not achieve the desired result, the next step is usually to prescribe medication to treat high blood pressure. The most common types of medications are ACE inhibitors, calcium channel blockers, and diuretics. Often a doctor will prescribe multiple drugs, as each drug can lower blood pressure by a small amount, with multiple drugs increasing the benefit. |

After a few years in the market, and their emergence has led to
prejudice and false beliefs, which were eliminated. In the early stages
of research and clinical use, has proven highly effective with few side
effects. Today, sildenafil citrate, known as Viagra has become one of
the most used drugs, and that in recent years, its worldwide sales rose
a dizzying manner. Commotion by the appearance of the famous pill, which was originally developed Viagra (sildenafil citrate) as a treatment for heart problems. However, later studies showed that this pill also increased blood flow to the penis, so quickly was considered effective for the treatment of erectile dysfunction (impotence). Viagra was approved by the Agency of food and medicine in the United States in 1998. Since then it has become popular, and today is available in over 90 countries. Has proven effective in treating impotence. |  |
 | This may be caused by aging, vascular disease, diabetes,
prostate operations, spinal cord injuries and even have psychological
origins. Sildenafil, which is marketed under the name Viagra, favors
the increase of blood supply to the penis, causing erection. But this
drug only works when the man is sexually aroused. Despite the
upheaval that brought the advent of Viagra, in the medical, media and
popular at first sales were not expected and the acceptance by the
patients was with some trepidation and reluctance. However, sildenafil
is a drug, both in the stages of research and in clinical use, has
proven highly effective with few side effects. It is important to note that this is a drug for a specific medical and psychological condition: erectile dysfunction. Although there are people who use it to improve sexual performance, and is even being considered for use in women. |
Along with the emergence of Viagra media began reporting the deaths allegedly attributed to the product. Should be clarified, in addition to bad that some patients make use of any drug, the FDA (Food and Drug Administration) requires a report every time you get a new drug on the onset of disability, death, injury and side effects those who are taking, whether or not caused by it. In the past two years has noticed the ease with which certain drugs are purchased over the Internet, and Viagra is the most sold through this channel. This really is a danger because they can be sold to patients for whom is not indicated, causing health problems or simply not giving results.
When to take
A complete medical examination and review of the patient's medical history should be performed to determine a diagnosis of erectile dysfunction, and so detect and identify probable causes appropriate treatment. For most patients, we recommend a dose of 50 mg, which should be eaten an hour before sexual activity. However, Viagra can be taken anytime within a range from four hours to half an hour before intercourse. The maximum dose can reach 100 mg or decreased to 25 mg, but the maximum recommended dose is once daily, no more.
Benefits of Viagra
Mainly, Viagra helps to regain confidence in sexuality and sexual relationships of men suffering from erectile dysfunction. Allows you to have and maintain an erection, orgasm, and restore the pleasure during sexual encounter. These benefits improve the quality of life and interpersonal relationships.
