Can Estriol Cream Cause Constipation? | PYHP 103

Mary’s Question: Hi. I just started estriol cream a couple of weeks ago. I am fifty-three years old and have been told I have PCOS for the past twenty years with a history of absent periods, heavy facial hair growth, and moodiness, and PMS. I have managed my PCOS through diet change, supplementation, and exercise. And I am told I am quite healthy. I began taking the estriol cream for bladder urgency and frequency and for the mucous membrane support for vaginal dryness. Sex had become very painful. I am experiencing some really wonderful positive benefits from the estriol. And in some ways, I realize I have probably been short of this for many many years likely due to the malfunctioning of my ovaries with the PCOS. The skin over my shinbones that has always been flaky no matter how much I moisturize, now, is soft, smooth, and supple for the first time in many years. The skin on my elbows, knees, and heels is softening. And it seems to have helped my skin tremendously. Even my facial hair is coming in much lighter. It seems to be reducing my belly fat in some ways. It is kind of a miracle. And I wish I had known about this years ago. The possible deal-breaker here is that I have become so painfully constipated over the past few weeks. And the estriol cream is the only thing that has changed. I also take bioidentical progesterone in a troche form which I have been taking for about ten years without a problem. The estriol is the only thing that has changed. The only time I can remember being this consistently constipated over a long period of time was during my two pregnancies. Any thoughts?
Short Answer: For constipation, the common advice is to drink more water and eat more fiber. However, for some, this does not work. It may seem strange to think that bioidentical hormones could impact digestion, but it is certainly possible for either progesterone or estrogen to cause someone to become constipated. We look at constipation as being a liver issue. Taking hormones can put a slightly extra burden on the detoxification capacity of the liver, which can slow down digestion.

Dr. Davidson: How is your summer going? 
Dr. Maki: Well, it is a rhetorical question, because I know exactly how your summer has been, because mine has been pretty much the same as yours. So I cannot complain. But you are right. It is going by way too fast. I cannot believe it is already August. But we still have a couple of months of nic
