gobbles - I gained weight, and I think I will be trying forever to lose it. I was on the Pill for 10 years, starting my freshman year in college, and instead of the “Freshman 15,” I gained the “Freshman 50.” But I had doctors who were honest with me, so a lot of that was my own fault.
There is another thread out there on the SDMB somewhere about, ahem, “sexual side effects” of the Pill, where I posted that I read the insert that came with my Pills every month. Said inserts did say that weight gain can be a side effect, at least for my Pill (I was taking Triphasil 28). Both my gyn and my regular doctor told me as much when I started the Pill.
However … I believe my weight gain was MUCH more than normal. My eating and exercise habits both changed significantly (and for the worse) when I started college. Both of my sisters are on the Pill - different ones, and different from the one I took - and they did have some slight weight gain that they were able to combat with minor changes to their exercise routines. Also, drinking extra water helps.
Just based on what I have heard from friends and family on the Pill, Ortho Tri-Cyclen is one of the worst Pills for weight gain. Hormones tend to do that to people - I have heard tell of some people who gain 20 pounds in the first month of their Depo “cycles,” then they lose the weight before their next shot, only to gain weight again. Little changes in hormone levels can affect your metabolism in big ways.
My best advice is this: talk to your doctor. If you don’t like the answers s/he gives you, talk to a different doctor or someone at your local Planned Parenthood office (or a similar-type clinic). Ask your friends who their doctors are, and talk to their doctors until you find a doctor who will answer your questions. You may find yourself with a new doctor, but it is worth it.
One other thing … there are ALWAYS work-arounds to weight gain from any kind of birth control, but you need to talk to your doctor about it. Sorry to preach (I didn’t mean for this to be so long), but I would hate for you to find yourself in a position you don’t want to be in because someone else didn’t answer all the questions you had (interpret however you want).
