Exercise after LIS surgery

What this experience covers

This experience looks at when and how people return to exercise after lateral internal sphincterotomy (LIS) surgery for an anal fissure. It is a composite drawn from many anonymised accounts and covers the common patterns — the cautious first walks, the gradual return to activity, and the signals people use to gauge whether they are ready.

The pattern

Week 1: rest and gentle movement

Most people describe the first week as focused on recovery rather than exercise. The main physical activity is short, gentle walks — often just around the house or garden at first, progressing to short walks outside by the end of the week.

People describe these walks as serving two purposes: preventing blood clots and stiffness, and providing a mental break from being at home recovering. The walking is slow, deliberate, and usually short — ten to fifteen minutes at most.

Activities to avoid in week one: lifting anything heavy, sitting for extended periods, any impact exercise, and anything that involves straining.

Weeks 2 to 3: cautious increases

By the second week, most people are walking longer distances — twenty to thirty minutes at a comfortable pace. Some describe starting gentle stretching, particularly for the upper body and legs.

The key message from these accounts: people listen to their body closely during this period. If a walk causes discomfort in the surgical area, they scale back. If it feels fine, they gradually extend.

Activities people commonly add in weeks two to three:

  • Longer walks at a moderate pace
  • Gentle yoga or stretching (avoiding deep squats or poses that put pressure on the pelvic floor)
  • Light household activities
  • Short drives (when comfortable sitting)

Weeks 4 to 6: returning to more

This is when the range of experiences widens significantly. Some people feel well enough to return to the gym, swimming, or cycling by week four. Others are still taking it carefully at week six.

Common activities people try in this window:

  • Swimming — frequently mentioned as one of the first “proper” exercises people try
  • Cycling — with a padded seat, often starting with stationary bikes
  • Light resistance training — upper body first, avoiding heavy lifting
  • Jogging — usually short distances, building gradually

Beyond six weeks: full return

Most people describe being back to their pre-surgery exercise level by eight to twelve weeks, though some take longer. Heavy weightlifting and high-impact activities are typically the last to return.

What people wish they had known

  • That the return to exercise is genuinely gradual — weeks, not days
  • That walking is exercise in the early weeks and it counts
  • That one bad day after doing too much does not mean they have caused damage — it usually means they need to scale back temporarily
  • That sitting on hard surfaces (gym benches, bike seats) takes longer to become comfortable than they expected

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.
