Very Low Risk for breastfeeding

Safe. Compatible.
Not risky for breastfeeding or infant.

Insulin is a component present in breast milk that helps to lower the risk for Diabetes Mellitus Type I among breastfed infants.

A small quantity of insulin is absorbed orally which is a factor that promotes maturation of the intestine, induces glucose tolerance and prevents development of Diabetes type 1.

Insulin requirements decrease about 25% after birth in diabetic mothers who breastfeed their babies. Those mothers are in need of higher self-control of disease, and, higher caloric intake is required (500 to 800 kcal/day).

Attachment and nursing should be started as soon as possible since second stage of Lactogenesis may be delayed in diabetic mothers.

Diabetic mothers who breastfeed would attain a better metabolic control of the disease while breastfeeding.


We do not have alternatives for Insulin since it is relatively safe.

Suggestions made at e-lactancia are done by APILAM´s pediatricians and pharmacists, and are based on updated scientific publications.
It is not intended to replace the relationship you have with your doctor but to compound it.

Your contribution is essential for this service to continue to exist. We need the generosity of people like you who believe in the benefits of breastfeeding.

Thank you for helping to protect and promote breastfeeding.
