Breastfeeding Does NOT sag New Mother's Breast

Breastfeeding won’t make a new mom’s breasts sag, but having more babies might, a new study indicates.
“A lot of times, if a woman comes in for a breast lift or a breast augmentation, she’ll say ‘I want to fix what breastfeeding did to my breasts’,” University of Kentucky plastic surgeon Brian Rinker told Livescience. So he decided to study any possible connection. Rinker and his colleagues interviewed 132 women who came in for breast lifts or augmentation between 1998 and 2006. On average, the women were 39 years old, and 93% had experienced at least one pregnancy. Among the mothers, 58% had breastfed at least one of their children. The average duration of breastfeeding was nine months.
The researchers evaluated the study particpants’ medical history, body mass index, pre-pregnancy bra cup size and smoking status.
The results of the study, presented this week at a conference of the American Society of Plastic Surgeons, showed no difference in the degree of breast ptosis (or sagging) between women who breastfed and those who didn’t. The main factors that did affect sagging were age, smoking status and the number of pregnancies.
Rinker noted that the smoking connection made sense because “smoking breaks down a protein in the skin called elastin, which gives youthful skin its elastic appearance and supports the breast”.
Pregnancy also “has a very strong contribution to breast ptosis (sagging)”, Rinker said. “In fact, our study showed that those negative effects increase with each pregnancy.”
Rinker says this finding should alleviate the fears of new mothers over what nursing their child might do to their breasts in the long run and will encourage them to breastfeed because of the health benefits to their infant. “Women may be reluctant to breastfeed because of this unfounded myth that doing so means the end of youthful breasts,” Rinker said. “Now, expectant mothers can relax knowing breastfeeding does not sacrifice the appearance of their breasts.”

Long-Term Breastfeeding Does Not Reduce Children's Risk Of Suffering Asthma

Long-term breastfeeding, while famously rich in nutrients for baby, does nothing to reduce the risk of developing childhood asthma and allergies, a new study suggests.

Canadian and Belarusian doctors recruited 17,046 breastfeeding women who were attending maternity clinics in Belarus in the late 1990s.

The volunteers were split into two groups.

In one group, the women (and the healthworkers at the maternity clinics) carried out their normal practices and policies of breastfeeding.

In the other, breastfeeding was promoted and supported, with the result that more infants of women in this group were breastfed exclusively for their first three months of life, and for longer periods, at up to 12 months.

When the children reached the age of six and a half, they were tested for any symptoms of asthma and their parents were asked to detail any symptoms of wheezing, chest tightness, hay fever and eczema.

In addition, the children were given allergy pricks to test for any response to house dust mites, cats, birch pollen, mould and grass pollen.


A total of 13,889 youngsters were followed up this way.

There was no difference between the groups on the questions of asthma, hay fever or eczema - and the results from the allergy pricks showed that in the "pro-breastfeeding" group, the youngsters were more sensitive to dust mites and grass pollen than their counterparts.

"These results do not support a protective effect of prolonged and exclusive breastfeeding on asthma or allergy," say the investigators, led by Michael Kramer of The Montreal Children's Hospital, Canada.

They note that asthma and allergies have surged in incidence in the past few decades while breastfeeding has enjoyed a renaissance.

This "strong suggests that breast feeding does not have a potent protective effect (against these disease) at population level."

In 2002, a smaller study, conducted among 1,037 New Zealand infants, found that babies who had been breastfed for more than four weeks rank almost double the risk of contracting asthma and allergies in their childhood compared with counterparts who had been fed on infant formula.
