The top weight loss drugs are provided by prescription under the supervision of a doctor. Weight loss medications are typically recommended for use only in patients who are moderately to severely obese and have struggled to lose weight with diet and exercise alone. These medications are usually prescribed as a part of a complete medical weight loss program that includes behavioral counseling, medical monitoring, and ongoing education about proper exercise and nutrition.
Types of Medications
The most widely prescribed weight loss drugs are appetite suppressants and lipase inhibitors. Appetite suppressants such as phentermine and diethylpropion are typically prescribed for short-term use and they reduce hunger, allowing the individual to consume less food. Lipase inhibitors, such as orlistat, block the absorption of fat in the gastrointestinal system, which allows the body to burn off pre-existing weight.
Results
According to the National Institutes of Health, individuals who use weight loss medications lose an average of ten pounds more than patients who do not. Long term weight loss results are typically seen six months or more after use, but short-term health benefits, such as lower blood pressure and cholesterol levels, can be observed in as little as 12 weeks.
Side Effects
Health providers such as the Mayo Clinic and The National Institutes of Health note that weight loss medications have a variety of potentially uncomfortable side effects. Appetite suppressants can cause an increase in blood pressure and heart rate and are often associated with restlessness, anxiety, and insomnia. Lipase inhibitors, such as orlistat, can cause a variety of gastrointestinal issues, such as diarrhea, gas, and oily stool. Medical supervision is highly recommended for safe use of these medications.
Expert Tips
Individuals who use medications to assist their weight loss program should also seek behavioral and nutritional counseling to prepare them for long-term lifestyle changes after the use of medication. These drugs can help you to lose excess weight, but severely overweight and obese individuals will typically only maintain their weight loss by learning new diet and exercise habits. A healthy, balanced diet and daily physical activity are the basis of any successful weight management program.
