The possibility of long-term pharmacotherapy is under consideration, but few clinical trials have been carried out for more than one year. Drugs are sometimes used as an intermittent treatment for patients who relapse to help curb weight regain before it undermines the previously successful weight loss. The scale and complexity of the epidemic of obesity makes this one of the most daunting problems facing healthcare professionals. Pharmacists can play a key role by providing accurate information, independent advice and long-term support to their patients. In particular, there is a need to recognise the limitations of current drug treatment and foster a desire among the public to take responsibility for their own weight today, by making appropriate changes in their lifestyle, rather than waiting for a magical cure tomorrow.
Pharmacists can become more involved in the management of obesity in a number of specific ways.
Identify those patients who would benefit from weight loss. Recognise the health risks of obesity and the benefits of weight loss. Reinforce the campaigns to promote a healthy lifestyle, including a low-fat diet and increased physical activity. Provide ongoing support and encouragement to overweight and obese patients.
