Weight-loss drugs can cause nausea, fatigue, and dehydration during treatment and are being misused for minor weight loss despite not being designed for that purpose. The body develops more fat-storing cells during weight gain, making it harder to maintain weight loss afterward—a biological mechanism creating the rebound effect.

Consumers face potential health risks from weight-loss medications including nausea, fatigue, and dehydration. Long-term effectiveness is questioned as rebound weight gain is common, making these treatments economically inefficient for households investing in repeated medication cycles and health complications.
Regulatory bodies may need to strengthen approval criteria and labeling requirements for weight-loss pharmaceuticals, similar to depression medications. Potential restrictions on off-label use and marketing practices. Healthcare systems may face increased costs from treating rebound obesity and medication side effects.
