Fatter mothers behind rise in perinatal complications

The increasing BMI of first-time pregnant women is behind a rise in adverse perinatal outcomes over a 25 year time period, a new retrospective Australian study suggests. Analysing data from one major Sydney teaching hospital, researchers found that the prevalence of overweight among women having their first baby increased from 12.7% in 1990-94 to 16.4% in 2010-14, and that of obesity rose from 4.8% to 7.3%. More importantly they found this increase in BMI was associated with a range of adverse perinatal outcomes particularly pre-eclampsia, macrosomia and gestational diabetes. Other complications believed to have increased as a result of the maternal weight gain included caesarean deliveries, post partum haemorrhage, prematurity, admission to the special care nursery and fetal abnormalities. “We found that a substantial proportion of the burden of adverse perinatal outcomes for Australian women is linked to maternal overweight and obesity, and that this proportion has steadily increased over the past 25 years,” the Sydney researchers said. The study involved the analysis of the data recorded on over 42000 singleton births delivered to previously nulliparous women at the Royal Prince Alfred Hospital Sydney between 1990 and 2014. Interestingly over the course of the study period, the mean age for first time mothers rose from 28.7 to 31.6 years, however having adjusted for this as well as other possible confounders such as changing smoking rates, socioeconomic status, and country of birth of the mother the findings confirmed the relative risks of adverse perinatal outcomes had increased in association with rising prevalence of overweight and obesity. Researchers calculated that should overweight or obese women move down one BMI category (for example from obese to overweight) 19% of pre-eclampsia, 15.9% of macrosomia and 14.2% of gestational diabetes could be averted. “Our results indicate that the frequency of adverse perinatal outcomes could be reduced by shifting the distribution of overweight and obesity among first-time mothers by a single BMI class. Investing in obesity prevention strategies that target women prior to their becoming pregnant is likely to provide the greatest benefit,” they concluded. Ref: MJA doi:10.5694/mja17.00344

Pregnancy doesn’t ‘cure’ endometriosis, so where does this advice come from?

Many Australian women with endometriosis are reporting they’re being advised a reliable treatment or even possible cure for their endometriosis is to “go away and have a baby”. This message is consistent with what women from other countries are also being told by a wide range of sources from self-help books to web forums to medical professionals. Pregnancy as a natural cure for endometriosis appears to date back to the early 20th century. However, even into the 1950s and 1960s, when pregnancy was commonly recommended as a treatment for endometriosis, this evidence was based mostly on case reports of women whose endometriosis improved during pregnancy. Case reports are often unusual findings and don’t necessarily reflect what happens to most people. Pregnancy as a treatment for endometriosis does not appear in current international guidelines for the management of endometriosis. It’s also not mentioned as a treatment by Australian pelvic pain specialists and is classed as a “myth” by reputable endometriosis support sites.

Endometriosis and the lack of a cure

Endometriosis is the presence of tissue similar to the lining of the uterus outside the uterus itself. Accurate estimates of how many women in Australia have endometriosis are hard to find, but a common figure is around one in ten women during their reproductive years. While severe pain during the period is a common symptom of endometriosis, it’s so much more than just a “really bad period”. There’s almost no area of women’s lives that is not negatively affected by the condition. Current medical treatments, often using hormone therapy, are not always effective. And the side effects of many of the hormonal treatments can be particularly unpleasant for women, leading them to stop treatment. Excision surgery, in which the endometrial lesions are cut away, is the most effective current treatment. But surgery is not something most women enter into lightly, given the cost and risk of undergoing surgery. Unfortunately, even surgery is not always successful with around 50% of women having symptoms reoccur after five years. When we look at women around the world, it looks like having children does decrease the amount of period pain women have. A significant problem with this is we don’t know if these women had endometriosis, and these kinds of studies can’t tell us for sure if getting pregnant was responsible for this reduction in period pain.

Pregnancy, pain and the brain

Women with endometriosis, like other chronic pain conditions, have changes in the way their brains process pain. Nerves, especially in the pelvis, are also more sensitive than in women without chronic pain. The concept of “calming” these hyperactive pain pathways is an important treatment strategy in treating chronic endometriosis pain. Each time menstruation occurs it irritates these sensitive nerves and reinforces these pain pathways. One way to prevent this reinforcement of pain pathways can be by stopping regular menstruation entirely. This is a key reason women with endometriosis are so often treated with continuous use of hormonal contraceptives. During pregnancy there’s also a suppression of menstruation. So it’s possible during pregnancy there will be a reduction in endometriosis-related pain. It’s also just as possible pregnancy will make endometriosis-related pain worse, due to extra pressure on these sensitive pelvic nerves. We just don’t have the research to be able to answer this.

After giving birth, it’s quite possible the pain, if it had decreased, will return. This is especially true once women start having regular periods again, as there’s no evidence pregnancy shrinks endometrial lesions or changes pain processing in the long term, both major drivers of endometriosis pain.

Should pregnancy be recommended as a treatment?

Pregnancy might help reduce endometriosis symptoms, if only temporarily. But women with endometriosis often rightly feel upset and offended when advised to have a baby as a treatment strategy. There are also risks involved, as women with endometriosis are more likely to have pre-term births, increased rates of caesarean sections and an increased risk of miscarriage. Women shouldn’t have to bring another human into the world to relieve the pain of endometriosis. This is why we need to prioritise understanding the cause of endometriosis, finding effective treatments and eventually a cure.

Could It Be Endometriosis?

Endometriosis, or more particularly diagnosis of endometriosis is often a challenge in general practice. When should you start investigating a young girl with painful periods? Is it worth investigating or should we just put them on the Pill? At what point should these young women be referred? Consequently, the most recent NICE guidelines on the diagnosis and management of endometriosis, published in the BMJ will be of interest to any GP who manages young women. According to the UK guidelines, there is commonly a delay of up to 10 years between the development of symptoms and the diagnosis of endometriosis, despite the condition affecting an estimated 10% of women in the reproductive age group. Endometriosis should be suspected in women who have one or more of the following symptoms:

chronic pelvic pain

period pain that is severe enough to affect their activities

deep pain associated with or just after sex

period-related bowel symptoms such as painful bowel movements

period-related urinary symptoms such as dysuria or even haematuria

Sometimes it can be worthwhile to get the patient to keep a symptom diary especially if they are unsure if their symptoms are indeed cyclical. Women who present with infertility and a history of one or more of these symptoms should also be suspected as having endometriosis.

Investigations

With regard investigations, the guidelines importantly state that endometriosis cannot be ruled out by a normal examination and pelvic ultrasound. Nonetheless after abdominal and pelvic examination, transvaginal ultrasound should be the first investigation to identify endometriomas and deep endometriosis that has affected other organs such as the bowel or bladder. Transabdominal ultrasounds are a worthwhile alternative in women for whom a transvaginal ultrasound is not appropriate. MRI might be appropriate as a second line investigation but only to determine the extent of the disease. It should not be used for initial diagnosis. Similarly, the serum CA-125 is an inappropriate and unreliable diagnostic test. Diagnostic laparoscopy is reserved for women with suspected endometriosis who have a normal ultrasound.

Treatment

If the symptoms of endometriosis can’t be adequately controlled with analgesia, the guidelines recommend hormonal treatment with either the combined oral contraceptive pill or progestogen. Women need to be aware that this will reduce pain and will have no permanent negative effect on fertility. Surgical options to treat endometriosis need to be considered in women whose symptoms remain intolerable despite hormonal treatment, if the endometriosis is extensive involving other organs or if fertility is a priority and it is suspected that the endometriosis might be affecting the woman’s ability to fall pregnant. All in all, these guidelines from the Royal College of Obstetricians and Gynaecologists don’t offer much in the way of new treatments but they do provide a framework to help GPs manage suspected cases of endometriosis and hopefully reduce that time delay between symptom-onset and diagnosis.
