Weight gain is a problematic side effect for many patients who take Lithium. Unfortunately, it is unclear as to why this is. One theory is that Lithium alters the endocrine system, which results in a lowered metabolic rate. This causes the body to burn fewer calories than when it is at a normal level. Another theory is that Lithium works to raise serotonin levels in the brain, which increases appetite. Approximately 75% of people who take Lithium will experience side effects. To understand that weight gain is a possibility and to make a plan of action ahead of time is the best way to maintain a healthy weight while taking Lithium.
Discuss concerns about weight gain with the prescribing doctor. Lithium tends to cause weight gain at higher doses. Work with the doctor to take the lowest dose possible. Learn his experience with the drug and whether or not weight gain has been common among patients he has treated.
