About 20 percent to 30 percent of women with MS experience a relapse within the first three to four months after giving birth and there are no interventions for effective prevention of postpartum relapse. The effect of exclusive breastfeeding on postpartum risk of MS relapse is controversial with conflicting study results.
Kerstin Hellwig, M.D., of Ruhr-University Bochum, Germany, and coauthors analyzed data from 201 pregnant women with MS collected from 2008 to June 2012 with one-year follow-up postpartum in the nationwide German MS and pregnancy registry. Exclusive breastfeeding was defined as no regular replacement of breastfeeding meals with supplemental feedings for at least two months compared with nonexclusive breastfeeding, which was partial or no breastfeeding.
