Weight gain results from a variety of issues, including eating larger portions, inactivity and heredity, according to MedlinePlus. The best way to drop pounds is through diet and exercise modifications. If these lifestyle changes aren't assisting in your weight loss, diet pills might be an effective option for weight loss. The most effective pills are available through prescription. Consult your doctor for advice that is specific to your medical situation.
How It Works
Prescription weight loss pills are approved by the FDA for effectiveness and safety. Short-term prescription weight loss drugs, such as phentermine and diethylpropion, are used up to 12 weeks to decrease the appetite. Orlistat, which is the only long-term drug approved for use by the FDA, works to minimize the amount of fat absorbed into the stomach. Orlistat is also available in a lower-strength pill, Alli, which is available for purchase at drugstores.
Benefits
Using prescription weight loss pills may result in 5 to 10 percent body weight loss, according to MayoClinic.com. Losing this weight has many health benefits, such as lower blood pressure, lower lipid levels and decreased blood glucose levels.
Considerations
Diet pills aren't usually used alone for weight loss. The pills are part of a healthy routine, including diet and exercise modifications. The Healthy Weight Pyramid tool developed by MayoClinic.com allows you to learn the appropriate servings of food groups based on your height, weight, age and gender. Physical activity should involve 150 minutes of activity each week, according to the Centers for Disease Control and Prevention.
Side Effects
As with any medication, prescription weight loss pills have risks and side effects. Orlistat side effects may include gas, stomach cramps and oil spotting, according to MayoClinic.com. Even though the FDA is also investigating potential liver side effects with Orlistat, it hasn't found any evidence of risk yet, according to MayoClinic.com.
Phentermine and diethylpropion may increase blood pressure, cause insomnia, dizziness and increased heart rate, according to MayoClinic.com.
Warnings
Not everyone is a candidate for prescription weight loss pills. You must have a body mass index of 30 or higher or 27 with weight-related health risks, according to MayoClinic.com. Partner with your doctor to review your health history and determine if you are a candidate for weight loss medications.
