CAN BIRTH CONTROL PILLS CAUSE ENDOMETRIOSIS?
Friday, May 8th, 2009Jacqui is a patient who for years suffered from infertility problems related to endometriosis. After surgery and medication, she was able to conceive two children. Now it appears that her disease is under control. When Jacqui came for a routine examination last spring, she mentioned that her sister was taking high-dosage birth control pills.
“Franny has been telling me how bad she’s been feeling”, Jacqui said. “I think of myself when I hear her—I could swear that the symptoms sound just like she’s got endometriosis. Franny never had any problems like cramps and pain before starting the Hill. She’s got a bit of a weight problem, and that worries me, too. What are the chances that the Pill is giving her endometriosis?”
Birth control pills do not cause endometriosis. In fact, they were once considered the treatment of choice to control the disease. Oral contraceptives are a balance of estrogen and progesterone, and the pills vary in formula and dosage. Although we know that estrogen influences the growth of endometrial cells, it has not yet been implicated in creating mutant cells that may become endometriosis. Let’s take the next step. If we examined under a microscope the endometrial tissue of women on oral contraceptives, we would find that the cells have become somewhat abnormal. This abnormality renders them inactive; that is, as a result of retrograde menstruation, they will not implant themselves on host organs and grow there.
About half of all such women, in fact, have suffered from some form of uterine cancer. High-fat or cholesterol-laden foods are most responsible for weight gain, and researchers are finding that these treacherous tats have the ability to convert into estrogen or stimulate hormone production. Greater production of estrogen influences buildup of the endometrium, causing a heavier menstrual flow.
A family predisposition to the disease could be conclusive here. There is a good chance that Franny already had endometriosis before taking oral contraceptives. The likelihood it that the estrogen in the pill stimulated the growth of endometrial cells to a certain degree. And since being overweight has been connected to higher levels of estrogen, we would strongly recommend that Franny keep her weight down.
Women with Jacqui and Franny’s history of endometriosis may find themselves facing a problematic option upon reaching menopause: should they have hormone replacement therapy? Such hormone therapy, in the form of estrogen supplements, is prescribed to control hot flashes, loss of vaginal elasticity, and other signs of aging related to lowering of female hormone levels. Mild endometriosis can occur as a result of estrogen replacement therapy, and this is not just the case with lifelong sufferers, women without any disabling symptoms of the disease may find that the estrogen has activated dormant cells. Jacqui and Franny, and women who share their problem, may have to battle a recurrence of the disease when they reach menopause. Perhaps by that time, however, doctors will have found a cure that trees a woman from the disease throughout her lifetime.
Scientists seeking the organic causes of endometriosis have scrutinized genetics, chemistry of the body, the influence of stress, distress, and the tempo of a woman’s life, hormonal responsibility, and even emotional attitudes. Sometimes there is great excitement in a laboratory or a doctor makes an astute observation and our knowledge of endometriosis is increased. Each quest for information brings us closer to the answer of why. Progress is being made. Until we can cite the precise components that cause endometriosis, we can work with effective methods for controlling and preventing the disease. That begins with you: your body will tell you what’s wrong, but you must be able to communicate your symptoms to a doctor. For now, let’s take the emphasis off why and learn what you can do to help yourself by understanding the disease more fully.
