Giving bipolar patients Topamax (topiramate) plus lithium, the help stabalize mood, may help to maximize weight loss a new study suggests. Patients who had been taking Topamax (topiramate), lost an additional 3.7 pounds, on average, after lithium was add. Weight Loss with Lithium plus Topamax
Lithium increased weight loss by 3 to 9 pounds; average 3.7 pounds
Adding lithium to Topamax increased weight loss by 3.3 to 8.8 pounds.
One of the twelve patients did not lose any additional weight, while another gained 1.5 pounds.
The average weight loss after adding lithium was 3.7 pounds.
Lithium Dose: 600-1200 mg per day, average was 1009 mg
The average dose of lithium was 1009 mg per day. The range of dosing used was from 600 to 1200 mg per day.
Average BMI: 39
The average body mass index (BMI) of the patients was 39—severely obese.
Average age of obesity onset: 12-years-old
The average age when the patients became obese was 12-years-old.
Average age: 44-years-old
The average age of the patients was 44-years-old.
Gender: 11 of 12 were women
Eleven of the twelve patients—all but one—were women.
Topamax Treatment Duration
Had taken Topamax for average of 9 months
On average, patients had been taking Topamax (topiramate) for about 9 months to help with their weight and their binge eating.
Average dose of Topamax: 514 mg
The average dose of Topamax (topiramate) was 514 mg per day, with the range being from 75 to 900 mg per day.
Topamax for Binge Eating
Topamax controlled binge eating in two-thirds of patients
With Topamax (topiramate) alone, two-thirds of the patients—eight of twelve—had their binge eating under control.
Conclusion: Mood stabilization may be necessary to maximize weight loss in patients with biopolar disorder and binge eating
“Optimal weight loss treatment in obese patients with comorbid bipolar and [binge eating disorders] may require stabilization of mood,” the study concludes.
Comments: I’m surprised. Lithium usually associated with weight gain
I’m surprised by this study.
Lithium is associated with weight gain.
The results are nothing fantastic—an additional weight loss of about 4 pounds—but nevertheless, it is interesting.
It is important to keep an open mind to new ideas.
