It takes about 1-3 months for the milk to disappear completely after weaning, and some people may need 1 year or even longer. If the period is not accompanied by breast pain and swelling, most of them are normal and there is no need to panic. After weaning, the hormonal changes in women’s body need time to recover, and most of them can be fully restored to normal level in about 1 month without external environmental stimulation. However, the specific time depends on each individual’s diet and the stimulation of the breasts. When the stimulation of the breasts is continued, the disappearance of breast milk can be delayed to a certain extent, but generally not more than 1 year. It is also important to note that if a woman’s lactation remains large or gradually increases after weaning, it is recommended to visit a hospital promptly to rule out hyperlactation. It is recommended that women pay attention to keeping their breasts clean and hygienic after weaning to avoid retrograde bacterial infections, and that they pay attention to any abnormalities and go to the hospital for further examination and timely adjustment and treatment.
