At a glance
Anal fissures during pregnancy and the postpartum period are common. Hormonal changes, constipation, and the physical demands of delivery all contribute. Many people feel caught off guard by this symptom on top of everything else.
This page covers why fissures happen during this time, what safe self-care looks like, when to involve your provider, and what people report about postpartum healing timelines.
Why fissures occur in pregnancy and postpartum
Several factors come together to make this a high-risk time for fissures:
- Constipation from hormonal changes — progesterone slows the digestive system, making constipation more likely
- Iron supplements — commonly prescribed during pregnancy and known to cause harder stools
- Reduced physical activity — especially in the third trimester, which can slow digestion further
- Increased pressure — the growing uterus puts pressure on the pelvic area and can affect bowel habits
- Delivery itself — vaginal delivery involves significant strain on the perineal and anal area, which can cause or worsen a fissure
- Postpartum constipation — fear of pain after delivery, dehydration, and hormonal shifts can all contribute
Safe self-care during pregnancy
The foundation of fissure care remains the same, but some treatments need to be checked with your provider first.
- Fiber and hydration — increasing fiber through food or supplements and drinking plenty of water is generally safe and often recommended during pregnancy
- Sitz baths — warm water soaks are considered safe and many people find them soothing
- Responding to the urge — not delaying bowel movements helps prevent further hardening of stool
- Gentle movement — walking and light activity, as tolerated, can support digestion
- Stool softeners — some are considered safe in pregnancy, but check with your midwife or doctor before starting any
- Avoid self-prescribing topicals — some fissure ointments are not studied or approved for use in pregnancy. Always ask your provider first.
When to tell your provider
Many people hesitate to bring up fissure symptoms during prenatal or postnatal visits. Your provider has seen this before and can help.
Consider mentioning it if:
- You are experiencing pain with bowel movements
- You notice bleeding
- Constipation is persistent despite dietary changes
- You are avoiding bowel movements because of pain
- Symptoms developed after delivery and are not improving
You do not need to wait for the problem to become severe. Mentioning it early gives your provider the opportunity to help before things worsen.
Postpartum healing
After delivery, fissure healing depends on several factors. People commonly report:
- The first weeks are hardest — bowel movements after delivery can be painful, especially if there is also perineal tearing
- Consistency matters — people who maintain fiber, hydration, and sitz bath routines tend to report faster improvement
- Healing is not always linear — good days and setbacks are normal during recovery
- Most acute postpartum fissures improve — many people report significant improvement within a few weeks of consistent care
- Some become chronic — if a fissure has not healed after 6 to 8 weeks postpartum, it may need further evaluation
What tends to help
- Prioritizing fiber and hydration even when life with a newborn is chaotic
- Sitz baths after bowel movements — even a brief soak helps
- Accepting help so you can take care of basic self-care routines
- Talking to your provider early rather than waiting for symptoms to resolve on their own
What tends to make things worse
- Ignoring constipation because “it will pass”
- Skipping self-care due to the demands of a newborn
- Using over-the-counter treatments without checking with your provider
- Feeling that fissure symptoms are not “important enough” to mention at appointments
Talking to your doctor
Your midwife, obstetrician, or doctor can help. Useful things to mention:
- When symptoms started — during pregnancy or after delivery
- Whether constipation is a factor
- What self-care you have tried
- Whether symptoms are improving or getting worse
- Any concerns about treatments and breastfeeding safety
If you experience severe pain, heavy bleeding, fever, or symptoms that concern you, seek medical care.
