(Ivanhoe Newswire) -- Women with multiple sclerosis who exclusively
breastfeed for at least two months after giving birth may be less likely to
experience a relapse within a year of their baby's birth than new mothers with
MS who opt to forgo breastfeeding in order to restart MS therapies, according to
a new study.
Frequently, MS patients suffer from fewer relapses during pregnancy but there's
a high risk of relapse during the postpartum period, doctors said. Medications
used to treat MS are not recommended for use during pregnancy or breastfeeding,
so many women with MS must choose between nursing and resuming MS treatment.
In this study, researchers at Stanford University School of Medicine observed
that of the 52 percent of women with MS who did not breastfeed or who began
regular supplemental formula feedings within two months, 87 percent had a
postpartum relapse compared with 36 percent of the women with MS who breastfed
exclusively for at least two months postpartum.
Among those who did not breastfeed exclusively for two months, 73 percent said
their primary reason for doing so was to take their MS medications.
“Why breastfeeding might be beneficial in humans with an autoimmune disease like
MS has not been studies,” the authors said. “Studies of immunity and
breastfeeding, while plentiful, are predominantly focused on breast milk content
and health benefits to the infant. Little is known about maternal immunity
during breastfeeding.”
Although they believe larger studies should be done, the study's authors said
their findings suggest that women with MS should be encouraged to breastfeed
exclusively for at least the first two months instead of resuming medications.
