Phentermine is actually an appetite suppressant that is helpful in an effective weight loss, but what is noteworthy, is that, Phentermine is meant for a short term weight loss.

There are many drugs that work in coordination with the brain chemicals called nurotransmitters, like anti-depressants, stimulants etc. Phentermine, like many other prescription drugs, works with our brain chemicals- the neurotransmitters. Neurotransmitters are chemicals in our nervous system and brain that act as messengers, transmitting electrical messages between the cells (neurons) of the nervous system or brain. Some people have naturally low levels of neurotransmitters. This condition may lead to diseases such as depression, anxiety, panic attacks, and obesity, and others.

There is a particular class of neurotransmitters in the brain, called catecholamines which are released when Phentermine actually stimulates the neuron bundles in our brain. These neuron bundles include, basically the following three: - Dopamine, Epinephrine and Norepinephrine. Epinephrine was formally known as adrenalin and norepinephrine as noradrenalin.

Phentermine affects the hypothalamus gland in the central nervous system of the brain. It works by disrupting the transmission of signals from brain chemicals known as neurotransmitters thus feigning the brain to believe that the body is not hungry at all. This is perhaps due to Phentermine's effects on leptin levels in the brain. Leptin is a hormone secreted by the fat cells, playing an important role in the regulation of body weight by acting upon the hypothalamus gland in our nervous system. This suppresses appetite and burns body fat from the adipose tissue, the tissue specialized for fat storage. It is theorized that phentermine can raise levels of leptin which signal satiety. It is also theorized that increased levels of the catecholamines are partially responsible for halting another chemical messenger know as neuropeptideY. This chemical initiates eating, decreases energy expenditure, and increases fat storage.

Although Phentermine has been shown to be effective in weight loss yet it is not recommended to be used for a prolonged period of time. In fact it should be preferably used for less than six months. Studies show that subjects who took Phentermine along with a nutritious diet and exercise lost an average of 5 to 22 pounds more than the subjects who were on placebo. But in real life settings, results have been even better. Thus, this can be a motivation for all those who really want to win their battle of flab.
