Antidepressants Can Affect Breast Feeding

If a woman is planning on breast feeding, and has been having treatment for anxiety or depression that involves taking selective serotonin reuptake inhibitor (SSRI) drugs may find that it delays their ability to produce breast milk after their baby is born.

This study at the University of Cincinnati was just reported in the Journal of Clinical Endocrinology and Metabolism and its findings are significant.  Although this is only a small study, 87.5% of women on SSRI drugs had delayed milk delivery compared to 43.5% of those not taking the drugs.   Delayed milk production is an early breastfeeding difficulty faced by many women, particularly those who are first term time mothers, and defined as being over 72 hours after giving birth.  This difficulty also contributes to the mother ceasing to breastfeed before the recommended time. These women also are at risk of early cessation of breastfeeding.

SSRI drugs are the most commonly prescribed class of antidepressants and are typically used to treat ‘baby blues’ depression.  A more natural solution would be to turn to natural medicine such as St John’s Wort, or more particularly natural progesterone as that is the hormone that drops most dramatically after giving birth and the one that could most help elevate mood without any ill effects for the baby.

Smoking in Pregnancy can Permanently Affect a Baby’s Blood Pressure

A Swedish study has shown that babies born to women who smoked during pregnancy show evidence of persistent problems in blood pressure regulation that start at birth and get worse throughout their first year.

The study was reported in the journal of the American Heart Association and raises serious concerns that the seeds being sown in pregnancy will reap a lifetime of ill health for the baby. Normally, when a person stands, the heart rate increases and the blood vessels constrict to keep blood flow to the heart and brain and so there is a standard repositioning test to see how a baby’s blood pressure responds to tilting them upright during sleep. The results were dramatically different in those born to mothers who smoked during pregnancy compared to those who did not.

The non-smoking mothers (on average 15 cigarettes a day) saw only a 2% increase in blood pressure in their babies when they were tilted upright at one week of age and later a 10 percent increase in blood pressure at one year. But, the babies of smoking mothers saw the exact opposite with a 10% increase in blood pressure during a tilt at one week and only a 4 percent increase at one year. At three months and one year, the heart rate response to tilting in the tobacco-exposed infants was abnormal and highly exaggerated, researchers reported.

The concern obviously is that early life exposure to tobacco can lead to long-lasting reprogramming of the baby’s blood pressure control mechanisms. The researchers found that such babies have a hyper-reactive system in the first weeks of life because the blood pressure increases too much when they are tilted up, but at one year they under-react and are less effective in adapting to an upright position. Despite any amount of health warnings some mothers still do smoke, and one argument I have heard is that it is better to smoke as it reduces the mother’s stress levels. A stressed mother is certainly not good for the baby, but this research shows the long-term implications are even more serious if she continues to smoke – or those around her do.

Birth defects – How men can help

Women are encouraged in pregnancy to have a reasonably high intake of folic acid as it is known to help prevent neural tube birth defects, but now an important groundbreaking study shows that a father’s intake of the nutrient might also be just as important.

Men with a high intake of folic acid are significantly less likely to produce sperm with the chromosomal abnormalities that can lead to birth defects.

Researchers from the University of California at Berkeley analyzed sperm from 89 healthy, non-smoking men for a condition called aneuploidy, in which a sperm cell carries the wrong number of chromosomes. While in most cases, aneuploidy leads to either a failure to conceive or to miscarriage, sometimes the foetus can be carried to full term where conditions such as Down’s, Klinefelter’s or Turner’s syndrome (sexual chromosome abnormalities) occur.

Men who want to make the best contribution to having a healthy child should start making changes at least 3 months before they want to start a family as it takes that time to produce sperm. Although you can take folic acid supplements, a good place to start would be to make sure you are a non-smoker, and include plenty of folic acid rich foods such as liver, green leafy vegetables, broccoli, peas and brussel sprouts.

Pets and pregnancy – A warning

A new study shows that pregnant women who use flea and tick shampoos on pets may double the risk of autism in their children. This preliminary finding comes from the Childhood Autism Risks from Genetics and the Environment study (CHARGE) – a case-control study from the University of California Davis, in the US.

The results are part of an ongoing research project which is following 2,000 children – some with autism, some with developmental delay, and some with typical development – and compares individual genetic patterns with exposure to medications, chemicals, food products, and other environmental factors.

It is believed that it is pyrethrins, commonly used chemicals in insecticides, that may play a role in triggering autism in certain children. Pyrethrins are extracted from Chrysanthemum flowers and are regarded as low in toxicity and there are commercial pyrethrum formulas that are considered safe to use in food preparation areas where flies and other insects can be found. One other product where Pyrethrins are widely used is in lice-control shampoos for humans and pets.

As I mentioned earlier, this is only a preliminary study but it would be a sensible precaution for pregnant women to avoid contact with lice-control shampoos. Let someone else shampoo the dog, or look for shampoos that treat lice naturally with ingredients such as tea tree oil, and not pyrethrins.

Caffeine risk in pregnancy

Caffeine is a stimulant and too much of it can jangle your nerves and keep you awake, however for pregnant women it can have a far more serious impact. Caffeine, whether from coffee, chocolate or sot drinks like colas, has been linked to a higher risk of miscarriage reported this week by the American Journal of Obstetrics & Gynaecology.

Even a small amount of caffeine can increase the risk, but if the daily intake is the equivalent of at least two cups of coffee or five cans of a soft drink with caffeine, then women in the study were twice as likely to miscarry as women who never, or rarely, had any caffeine in their diet. Women who suffer a lot of nausea in pregnancy, and had a high caffeine intake, had an even higher risk of miscarriage.

The study was based on 1,063 pregnant women living in the San Francisco area and confirmed previous studies about the increased risk of caffeine intake and miscarriage. These studies found that caffeine crosses the placenta but is poorly metabolised by the foetus and may influence cell development and decrease placental blood flow.

To put it into perspective, the risk factor is substantially elevated if you have over 200mg a day from all sources and a large mug of 150 mill of coffee contains 100 mg of caffeine.

However, as I have previously mentioned in this article about caffeine, caffeine-free doesn’t quite mean what it says. It depends on a number of factors such as what process of decaffeinating is used and what different manufacturers product requirements and standards are.

Remember that there is approximately 2mg caffeine in decaf coffee and hot chocolate and if tea drinkers are not immune either as there is approximately 39 mg of caffeine in the average mug of tea.

High blood pressure in pregnancy may pose long-term risk

High blood pressure is closely monitored during pregnancy but there is new evidence from a study at the Mayo Clinic in the USA that it is an under-recognized risk factor for cardiovascular disease. Compared with women who have had normal blood pressure throughout their pregnancies, those who had high blood pressure are at greater risk of heart disease later in life. One reason could be that having high blood pressure in pregnancy has some of the same risk factors for cardiovascular disease such as diabetes or obesity. Another theory is that hypertension in pregnancy could induce long-term metabolic and vascular abnormalities that might increase the overall risk of heart disease later in life. Anyone with a family history of heart disease is well advised to have their blood pressure very closely monitored during pregnancy.
