Check whether the nipples are flat, inverted, or newly changed
See a doctor if the change is sudden, one-sided, painful, or associated with discharge, a lump, redness, or skin changes
Use gentle stimulation or cold exposure if the nipples are naturally flat and you want temporary protrusion
Try a nipple suction device or breast shell if recommended by a clinician
Discuss a nipple everter with a healthcare professional if appropriate
Address any underlying hormonal, developmental, or breast tissue causes with a doctor
Consider surgical correction only after evaluation by a breast specialist or plastic surgeon
Avoid squeezing, pinching, or aggressive manipulation
Get medical evaluation if you are pregnant, breastfeeding, or concerned about feeding issues
