With Lyme Disease, I gained 50 lbs, suddenly, but, at the time I was recently given anti-depressants, which I believe that and LD was the cause.

Then, in my treatment, long down that road and off all meds, I started on my way back down and lost 63 lbs in just a few months.

If you'll do a search, here of previous posts on the subject, you'll begin so see that most LD patients have either weight gain, or weight loss. Learn how to do a search by clicking this link:
