All you indoor cycle enthusiasts probably got the reference pretty quickly… Tap Backs are not only good for your core and your gluts but for your quads and your arms (and they are sort of fun at the same time). Dancing on a bike is liberating, to say the least, and lets you think, at least for 45 minutes, that you too could be Beyoncé’s next back-up dancer!
Tap backs are not just good for the body; they are good for the soul (no pun intended!). In the same way, add-back hormonal therapy is good for many different organs. With oral progesterone + estrogen, you are hitting many of those key areas and shaping your future.
Let’s take a seat in the saddle and review why you would need add-back therapy and how it does its job. Many GYN pathologies think fibroids, endometriosis, and adenomyosis run on hormones. No hormones usually = no pain/no symptoms. Therefore, our treatment choices for such problems frequently center on taking the hormones away. Our first line of attack usually includes oral contraceptive pills (OCPs). The synthetic estrogen and progesterone in OCPs feeds back on your brain and shuts off your natural production of estrogen and progesterone. It’s a complicated pathway of events, but this one daily pill is usually very good at putting the brakes on the body’s own hormone production and keeping those pesky symptoms (pain, bleeding) at bay.
However, in certain cases, the OCPs are no match for the pathology pervading your pelvis—in these instances, we need to look into our bag of tricks and pull out something more powerful. Cue GnRH agonists (a.k.a. Lupron). These injectable (and in some forms nasal) medications shut off the brain’s production of the hormones that stimulate ovarian estrogen production. They don’t waste their time with feedback but rather go right to the source and turn off that switch. And while they are good at keeping things dark when this switch has been flipped to OFF by Lupron, it’s like a major blackout occurred in your body.
Everything hormonal goes dark. And while this darkness is good for stopping endometriosis, fibroids, and the like, it is not so good for those organs that desperately depend on estrogen (think bones). Therefore, in order to satisfy both parties (those that like the dark and those that need some light), we give what is called hormonal add-back therapy alongside the Lupron.
Think of the add-back therapy as a flashlight. It shines light on the areas that are really afraid of the dark (a.k.a. the bones). And like all good nightlights, it does its job well—it can keep the bones happy without reducing the efficacy of the Lupron. It also quells those crazy hot flashes that women can get while taking a GnRH agonist (Lupron). You may be making a funny face, thinking this doesn’t really make sense? If endo is fed by estrogen and then the doctor gives estrogen, won’t that make matters worse? You are sort of right and also sort of wrong. Here’s why.
The doses at which you are taking oral add-back therapy are right at the hormone sweet spot. They are just enough to protect your bones and stop the hot flashes but not enough to fuel your disease (endo, fibroids, etc.). As a result, add-back therapy has become all the rage for women taking GnRH agonists (Lupron). By supplying it, we can give Lupron without much stress over the possible negative side effects. Examples of add-back therapy include norethindrone acetate alone or norethindrone acetate + estrogen. Either combo has been shown to work; however, what works for you must be figured out with your doctor. Most of the time, we start add-back right when the agonist is started. While we used to wait a few months before initiating add-back, we now don’t really think there is any benefit to delaying its start.
Whether you are a SoulCycle or a Flywheel girl, an Equinox fan or a Crunch crazy, you know that, while on the bike, you will burn a serious number of calories. Add-back therapy is the lubricant that allows those wheels to keep turning. Without a little juice, over time, the bike will break down, and you will come to a screeching halt. We want to prevent that in your body by giving add-back hormonal therapy alongside a GnRH agonist. It will allow you to keep “cycling” without much pain. Not bad… Now, let’s see you Tap It Back!
