How Phentermine Works: The Science Behind it

Phentermine is a drug that affects your central nervous system in order to suppress your appetite. However, it is a little bit more involved than this and it may help you to understand how this medication really works?

The science behind it might also help you determine whether this is a viable weight loss option for you. This information may change your life.

The Mechanics

Phentermine stimulates the nerve bundles which releases the following chemicals: catecholamines, these include dopamine, epinephrine (formally known as adrenalin), and norepinephrine (noradrenalin). The outcome is a fight or flight response, which helps suppress your appetite.

These neurotic chemicals (a.k.a. neurotransmitters) released stops your appetite by intercepting the “hunger message” that your brain would normally receive. There are many theories as to why this drop in appetite occurs, though.

One of the beliefs assigned to the cause of this decline in appetite is that phentermine has an affect on leptin levels. Leptin is the hormone responsible for satiety, which helps a person feel full and phentermine helps raise leptin levels.

Another theory behind this decreased desire for food is that neuropeptide Y transmission or production is stopped. This is the neurotransmitter that is responsible for impulses to eat, and it also encourages the storage of fat while inhibiting the expenditure of energy.

More Facts

Part of the reason why obesity occurs, among other mental and physical problems (anxiety, depression, panic attacks, and more) is due to low neurotransmitter levels. However, sometimes problems occur as a result of excess neuro transmitter production.

The focus of using a drug like phentermine is to provide balance. One school of thought suggests that this medication actually tricks the brain into thinking that there has been a certain level of nerve chemicals produced. Therefore, it stops or slows down the release of more.

Usage Info

Talk to your doctor before you try phentermine or any brand name equivalent such as one of these: Adipex-P, Ionamin, Obenix, Oby-Cap, Teramine, Zantryl. Numerous factors should be considered before you use this medication for appetite control.

For instance, have you been addicted to drugs or alcohol in the past? If so, this may not be the best solution for you because it is potentially habit-forming.

Another concern is whether you are pregnant or nursing. If so, talk to your doctor before you use it. You should also disclose any health conditions you have not yet shared with a medical professional before use, and be careful about mixing Phentermine with other drugs.
