body to retain water. There are many kinds of diuretics. Alcohol is one kind, but there are also natural diuretics that the body itself produces. Diuretics can be introduced orally or intravenously, but no matter the way they are taken they all cause the body to excrete large amounts of water (Donohue,81).Diuretics are used in sports by athletes who must weigh in before matches such as wrestlers and boxers. This is a help to the athlete because he/she can lose a lot of water weight just before the match without having to do extra exercise to work the weight off (Goldman,71). This is unfair to the other athletes who do it the harder original way and also have to lose a little bit of muscle mass to lose that extra pound unlike the athlete who uses the diuretic to get rid of the water weight and keep the extra muscle mass.There are several medical uses of diuretics. They can be prescribed for hypertension to lower a patients heart rate(Solomon,1). Also, it can be prescribed to patients who are at risk for stroke to lower that risk. Finally, diuretic can lower blood pressure when used with other medications. Diuretics, however, are being linked to and increased risk of hyponatraemia (low levels of salts needed in blood) and an increased risk is heart failure. In addition, the athlete also runs the risk of dehydration with urinating so frequently (Goldman,73).Human Growth Hormones (HGH) are chemicals produced in the pituitary gland in humans. HGH is also known as somatotropin. HGH is the chemical that makes kids grow. HGH, however, have now been produced in a laboratory (Goldman,108). HGH is difficult to test for because the structure of the molecule is almost exact to that of the one produced in the body (Growth,1).Athletes have gotten a hold of the laboratory synthesized HGH and use it to increase muscle strength and size. It is used by many different kinds of athletes including football players, body builders, basketball players, and w...
