Weight Loss Drugs Prescription and OTC »
Taking a weight loss drug may not result in weight loss by itself. But using diet pills can help an overweight person stay on a diet because nearly all of these medications work on suppressing appetite. "Feeling full" is believed to be related to a number of biochemical processes in the body. Signals to indicate fullness come from fat cells and the gastrointestinal tract; these converge with signals in the central nervous system. Appetite suppressants target a couple of key neurotransmitters in this process: serotonin and norepinephrine. Increased levels of serotonin result in a feeling of fullness. Increasing norepinephrine levels stimulate the central nervous system, decreasing appetite. Only one drug among the weight loss medications works in a different way. Orlistat (Xenical, Alli) works in the gastrointestinal tract to prevent absorption of about a third of ingested fat.
