First bowel movement after LIS

What this experience covers

This experience focuses on one specific moment in LIS recovery: the first bowel movement after surgery. It is the single event that generates more anxiety than any other part of the process. This is a composite drawn from many anonymised accounts.

The pattern

The build-up

People describe the anxiety about the first bowel movement as beginning before the surgery itself. It sits in the background during pre-operative preparation and surges the moment they wake up from anaesthesia. The question is always: how much will it hurt?

People who have been living with a chronic fissure have months of painful bowel movements behind them. The idea of passing stool over a fresh surgical site feels impossible.

The preparation

Every account that describes a manageable first bowel movement credits preparation:

  • Stool softeners started days before surgery
  • Fibre intake already established
  • Water intake high and consistent
  • Soft foods in the day or two after surgery

People who did not prepare — who started stool softeners on the day of surgery or the day after — consistently describe harder first experiences.

The moment

The first bowel movement after LIS typically happens one to three days after surgery. The range of experiences is wide:

  • Some people describe it as surprisingly easy — significantly less painful than their pre-surgery bowel movements
  • Others describe moderate pain that was manageable with deep breathing and prescribed pain relief
  • A smaller number describe significant pain, usually associated with harder stool consistency

The consistent finding: the stool consistency is the single biggest factor. Soft stools make it manageable. Hard stools make it very difficult.

Immediately after

People describe sitz baths as essential after the first bowel movement. The warm water soothes the area and helps with cleaning. Most people take their time — fifteen to twenty minutes — and describe the relief as significant.

Pain medication timing also matters. People who took their pain relief an hour before an anticipated bowel movement describe a better experience than those who waited until afterwards.

What people wish they had known

  • The anxiety is almost always worse than the reality
  • Stool consistency matters more than anything else
  • The first bowel movement does not predict the rest of recovery
  • Having a sitz bath ready and waiting makes the experience much better
  • It is okay if it takes a few days — not having a bowel movement on day one is normal

When to contact your doctor

Seek medical attention if you experience:

  • Heavy bleeding during or after the bowel movement
  • Pain that is extreme and does not respond to prescribed relief
  • No bowel movement for four or more days after surgery
  • Fever or signs of infection
  • Any symptoms that concern you

See all the signs

For this topic, get medical advice if you notice:

  • Severe or worsening pain
  • Heavy bleeding
  • Fever
  • Black stools
  • Fainting or dizziness
  • Pus or unusual discharge
  • Inability to pass stool or gas
  • Unexplained weight loss

Recording how you feel is not the same as being checked. These are the signs that need a doctor’s attention.

Call 911 or go to the emergency room now if you have:

  • bleeding that will not stop, a lot of blood (the toilet water turns red, or you pass large clots), or any bleeding with feeling faint or dizzy
  • fainting, a racing heart or trouble breathing
  • confusion or slurred speech, extreme shivering, no urine in a day, or blotchy skin
  • sudden severe belly pain, or a swollen, hard belly with vomiting or not passing stool or gas
  • you cannot pass urine at all, or your bladder feels full and painful and you can’t empty it
  • redness, swelling or severe pain spreading quickly around your anus, genitals or groin, especially with a fever or feeling very ill
  • a fever with a painful swelling near your anus if you have diabetes or a weakened immune system (for example, from chemotherapy or transplant medicines)
  • black, tarry stools

Call your doctor or go to urgent care today (or the ER if you can’t be seen today) if you have:

  • a temperature of 100.4°F (38°C) or higher, chills, vomiting, or feeling generally unwell
  • pain that is getting worse over days, or severe pain that stops you sitting or sleeping
  • a hot, swollen or very tender lump near your anus or at the top of the crease between your buttocks, or foul-smelling discharge
  • trouble urinating
  • bleeding that is getting heavier or more frequent, or blood mixed into your stool
  • feeling much more tired than usual, looking pale, or getting out of breath more easily than you used to
  • not passing stool for several days, or new belly pain

Make an appointment with your doctor if:

  • you have never had these symptoms checked by a doctor or nurse — whatever your age
  • you have had rectal bleeding for more than 3 weeks
  • your bowel movements have been looser, thinner or more frequent than usual for 3 weeks or more, or you have lost weight without trying
  • symptoms have not settled after a week or so, or keep coming back
  • you notice a new lump near your anus, between your buttocks or in your belly, or an itch or discharge that does not clear
  • you have new leakage or trouble controlling your bowels
  • you are 45 or over, or have a family history of bowel cancer or inflammatory bowel disease, and any of these symptoms are new for you

If you are unsure, it is always reasonable to ask. If things feel overwhelming, call or text 988 (Suicide & Crisis Lifeline) or chat at 988lifeline.org, any time. If you don’t feel safe, call 911.
