Which scenario is a contraindication to breastfeeding in many settings?

• A. Maternal HIV infection
• B. Maternal diabetes
• C. Maternal hypertension
• D. Maternal hypothyroidism

Answer: (A)

Breastfeeding safety depends on whether a maternal condition could be passed to the infant through breast milk or requires treatments that would affect the baby. When HIV infection is present and antiretroviral therapy is not accessible or reliably suppressive, breastfeeding can transmit the virus to the baby via breast milk, so it is considered a contraindication in many settings. In those contexts, alternatives like formula feeding are recommended to reduce the risk of mother-to-child transmission.

The other conditions listed—diabetes, hypertension, and hypothyroidism—are not contraindications to breastfeeding. With proper medical management (keeping diabetes under good control, managing blood pressure safely, and using thyroid hormone replacement appropriately), a mother can breastfeed. Some medications for these conditions may need to be reviewed for lactation safety, but none universally prevent breastfeeding.
