Although obesity in itself is associated with increased morbidity and mortality, massive, poorly monitored weight loss and/or weight cycling can have equally dire consequences. Among the important potential complications to watch out for in the setting of weight loss are the following:
- Cardiac arrhythmias;
- Electrolyte derangements – Hypokalemia is the most important of these;
- Hyperuricemia;
- Psychological sequelae – Including depression and the development of eating disorders (particularly binge-eating disorders);
- Cholelithiasis.
