It is true that losing weight is possible with the help of a low calorie diet and regular physical activities. However, some people, especially those who are severely obese may need some additional help along with a exercise program and a low calorie or low fat diet. Appetite suppressants are the medications that can help such obese people to lose weight. Appetite suppressants are usually helpful, when obesity is associated with sedentary lifestyle and over consumption. One of the widely popular appetite suppressants or diet pills in this regard is phentermine. Phentermine appetite suppressant was approved by the FDA (Food and Drug Administration) of United States in the year 1959, primarily for the short term treatment of obesity, when used in combination with exercise, diet and behavioral modification.
How Does Phentermine Work?
For anyone considering to take phentermine appetite suppressant for weight loss, it is quite natural to be a bit curious about how this diet pill works. Before we go into the details of how does phentermine work, it is important to mention that, this medication is used along with a low calorie diet, exercise and behavioral modification program, as approved by a physician. This appetite suppressant can help to lose weight only when it is used as per the direction given by the physician. Physicians usually prescribe this diet pill, when they feel that the health risks associated with obesity outweigh the side effects associated with the use of phentermine.
Phentermine works by helping to control appetite. It acts on the hypothalamus and the brain to suppress appetite or hunger. Hypothalamus is the part of the brain that regulates hunger, and phentermine appetite suppressant stimulates the hypothalamus to release certain neurotransmitters, which are known as catecholamines. Catecholamines signal the 'fight or flight' response of the body, thereby suppressing or overpowering the hunger signal. In this way, this weight loss pill helps to suppress appetite and reduce calorie intake. It also stimulates the body to release adrenaline or epinephrine, which speeds up the process of fat breakdown. You can buy Phentermine without prescription
