Other diet pills side effects are psychological disturbances. These effects include mood swings or instability, increased paranoia, anxiety, nervousness, depression and low self-esteem or body image (Addiction Hope, n.d.). This is due to the fact that some diet pills contain many harmful chemicals that have adverse effects on emotions. These effects can give direct and indirect consequences to teenagers’ lives. For example, teenagers who use diet pills may have depression that causes loss of interest in daily activities. Those who have nervousness caused by diet pills may have poor concentration or difficulty making decisions.
