Swelling of the areola during breastfeeding may be caused by the child taking milk, caused by the child sucking on the nipple for a long time or incorrect posture while breastfeeding. However, it is important to look for redness, swelling, heat and pain in the breast and check for mastitis. If mastitis is present, anti-inflammatory medication can be applied. If the inflammation develops further and there is a fluctuating sensation, areolar incision and drainage should be considered. If it is not serious, you can use magnesium sulfate or cactus for wet compresses, which can also play a role in reducing inflammation and swelling. Before the swelling of the areola subsides, it is important to avoid spicy and irritating foods, as well as overly oily foods. If you want to take anti-inflammatory drugs, you need to apply them under the guidance of your doctor and not on your own. If the pain in the swollen area is severe, breastfeeding needs to be suspended.
