Read guide →At a glance
Irritable bowel syndrome often brings colorectal symptoms along with it. Chronic constipation, diarrhea, and straining can contribute to conditions like fissures and hemorrhoids. Many people find themselves managing two things at once. Our symptoms guide covers the common overlaps and when colorectal symptoms need their own attention.
Common symptoms people report
- Constipation or straining during bowel movements
- Diarrhea or frequent loose stools
- Urgency — a sudden, intense need to go
- A feeling of incomplete evacuation after a bowel movement
- Pain or discomfort during or after bowel movements
- Abdominal cramping or spasms that affect the lower bowel

Common questions
Can managing IBS help with colorectal symptoms too?
Often, yes. When constipation or diarrhea improves, the downstream colorectal effects tend to ease as well. Many people find that addressing their IBS and any colorectal condition together — rather than treating them separately — leads to better results.
Is it common to have both IBS and a fissure or hemorrhoids?
It is very common. The straining and altered bowel patterns that come with IBS are closely associated with conditions like fissures and hemorrhoids. If you are dealing with both, you are not unusual — and it is worth discussing the full picture with your doctor.
Should I change my diet if I have IBS-related colorectal symptoms?
Dietary changes are one of the most common approaches people try. What helps varies from person to person. Fiber adjustments, hydration, and identifying trigger foods are commonly discussed starting points. Our constipation management guide covers what people report in more detail.
Why do my colorectal symptoms get worse during IBS flare-ups?
IBS flare-ups often involve changes in stool consistency, frequency, or both. These changes put additional strain on the anal area. People commonly describe a pattern where an IBS flare triggers or worsens a fissure, hemorrhoid symptoms, or general discomfort.

- Symptoms that have changed significantly or are getting worse
- Severe abdominal pain that is different from your usual IBS discomfort

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)

- 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.
