A tear or surgical incision requiring sutures is a common part of recovery after vaginal childbirth. Stitches (sutures) are used to bring together the edges of injured tissue around the vagina and perineum, the area between the vaginal opening and the anus. Their purpose is to stabilize the tissue layers, supporting the body’s natural ability to heal the wound. Understanding the materials used and the healing process helps manage expectations during the postpartum period.
Understanding Postpartum Sutures
The vast majority of sutures used for tears or episiotomies after birth are absorbable, meaning they are designed to break down within the body and do not require manual removal. These materials, often synthetic polymers, gradually lose their tensile strength as the body’s natural processes degrade them. Only in rare circumstances, or for more complicated surgical repairs, might a non-absorbable material be used, which would then need to be taken out by a healthcare provider.
The extent of the tearing dictates the number and depth of the stitches placed. Perineal tears are graded into four degrees based on severity. First-degree tears are minor, involving only the skin, and may not require stitches. Second-degree tears extend deeper into the perineal muscle and typically require suturing. Third- and fourth-degree tears are more complex, involving the anal sphincter muscle or the rectal lining, and require extensive stitching to repair multiple tissue layers. The depth of the tear affects the healing time because deeper repairs require more support from the sutures.
The Expected Timeline for Dissolution
The time it takes for absorbable stitches to disappear completely varies based on the material used and the depth of the repair, but a general timeframe is predictable. Most dissolvable stitches begin to break down and lose their strength within the first one to three weeks postpartum. This initial degradation occurs after the stitches have finished holding the wound edges together during the critical phase of tissue regeneration.
It is common to notice small pieces of thread in the toilet or on sanitary pads during this period, which is a normal sign of dissolution. While the stitches dissolve within a few weeks, the underlying tissue takes longer to fully heal. The tissue area usually requires four to six weeks or more to regain its full strength and flexibility. For more extensive repairs, such as third- or fourth-degree tears, the complete healing process can take six weeks or longer.
The type of suture material chosen also influences the timeline. Some materials are “fast absorbing,” designed to disappear quickly, while “standard absorbing” materials offer support for three to four weeks before fully dissolving. The goal is to match the suture’s lifespan to the time needed for the specific tissue layer to heal adequately. Pain and discomfort associated with the stitches should generally diminish steadily after the first week.
Managing Pain and Promoting Healing
Managing discomfort is a significant part of recovery. Applying cold therapy, such as an ice pack or a cold gel pad wrapped in a cloth, for 10 to 20 minutes at a time helps reduce initial swelling and pain. Positioning is also important; sitting squarely on the buttocks rather than leaning to one side helps prevent undue strain on the stitched area.
Maintaining cleanliness is paramount to prevent infection and promote healing. Using a peri bottle filled with warm water to gently rinse the perineum during and after urination helps dilute urine, which can cause stinging. After rinsing, gently patting the area dry with a clean, soft cloth or tissue, moving from front to back, is advised. Regular changing of sanitary pads also helps keep the area dry and clean.
Soaking in a shallow, warm bath, known as a Sitz bath, provides significant comfort by increasing blood flow to the area. Over-the-counter pain relievers, such as ibuprofen or acetaminophen, are recommended to manage pain and swelling. Staying hydrated and using stool softeners, if recommended, can prevent straining during bowel movements, which puts pressure on the healing stitches.
When to Contact Your Healthcare Provider
While some pain and discomfort is expected, certain signs indicate the healing process is not progressing normally and require immediate medical attention. If pain begins to increase significantly after the first week, rather than steadily decreasing, it may signal an underlying issue. This worsening pain, especially when accompanied by new or spreading redness, warmth, or excessive swelling around the stitches, should be evaluated promptly.
A fever of 100.4°F or higher, or a general feeling of being unwell, can be a warning sign of infection. A foul odor or an unusual discharge, such as pus, coming from the wound, is another concerning symptom, distinct from the normal postpartum bleeding (lochia). If the wound appears to open up or separate (dehiscence), or if there is excessive and persistent bleeding, contact your care team without delay.
