The sale of weight loss products has become an extremely large and profitable industry in the United States, as there is an epidemic of obesity, with physical appearances being focused on by the mass media. Appetite suppressants are an option that has existed for awhile, and they are intended to manager your hunger so you consume less calories throughout the day.
The hypothalmus (a part of the central nervous system) plays a key role in the successful use of appetite suppressants. Directly under the thalamus, just over the stem of the brain, is where the hypothalamus is. The responsibility for the control of a lot of your body, especially your appetite, belongs to the hypothalamus. When glucose levels fall to low levels, or the body senses a physical or emotional need for food, neurotransmitters are released by the hypothalamus to help fulfill the need.
Norepinephrine and serotonin are the two main neurotransmitters that control hunger. When the hypothalmus thinks you have had your meal, then it believes you are not hungry any more and makes appropriate hormones available to signal satisfaction to your brain. When you take an appetite suppressant it tricks your neurotransmitters into thinking you have already eaten. This full feeling can help you eat less food than you would normally would at mealtime, and help manage between meal cravings.
There are a few brands and types of suppressants for the appetite that are being sold. Two of the mainly employed appetite suppressants that are prescribed are Meridia, or sibutramine, and Adipex and Fastin, or Phentermine. Dexedrine, Adderall, and other amphetamines are occasionally prescribed for use as appetite suppressants, however, they can be addictive and lead to abuse, so they are only prescribed in extreme cases of obesity with close monitoring.
There is a chance of addition and dependence with all appetite suppressants that are prescription strength. Amphetmines can cause this also. There is also a chance of having an allergy to the suppressant’s ingredients. People with cardiovascular disease (e.g. arteriosclerosis, heart disease, high blood pressure) should not use appetite suppressants without a doctor’s supervision. Do not take other weight loss drugs with appetite suppressants.
