Can a lateral incision wound heal on its own if it has opened up?

In general, whether a lateral episiotomy wound that has reopened can heal on its own mainly depends on the size and location of the wound, as well as the individual's overall health. The specific analysis is as follows:

If the reopening of the episiotomy wound is small in extent, does not affect deep muscle tissues, and the individual has no underlying health conditions such as diabetes or malnutrition that impair healing, the wound can usually heal spontaneously under the condition of keeping it clean and dry. The body’s natural repair mechanisms will gradually restore the damaged tissue. During this period, avoid stretching or pulling on the wound to minimize interference with the healing process.

However, if the wound reopening is extensive, accompanied by persistent bleeding, discharge, redness, swelling, or pus formation, or if the individual suffers from conditions like diabetes or compromised immunity, spontaneous healing is unlikely. In such cases, the wound's healing capacity is weakened, increasing the risk of infection, delayed healing, or scar formation. Timely medical intervention is necessary to promote recovery.

After the wound reopens, wash the perineal area gently with warm water to maintain cleanliness, avoiding the use of irritating cleansers. Change cotton underwear frequently to reduce friction on the wound. Avoid excessive straining during bowel movements to prevent further wound separation. Increase intake of protein and vitamins in the diet to support tissue repair. Seek immediate medical attention if signs of infection—such as worsening redness and swelling, severe pain, or fever—develop, or if the wound fails to heal over time.
