Which doctor treats this
- Start with your primary care provider (family doctor or internist).
- They may send you to a gastroenterologist or a colon and rectal surgeon.
Living with it
- Keep a simple diary of symptoms, triggers, and medicines to bring to visits.
- Bring a list of your medicines and questions to each visit.
- Note which foods make symptoms better or worse.
- Eat smaller meals and limit alcohol.
- Long-term illness can affect mood. Tell your doctor if you feel down or anxious.
Back to school, work, or sports
- Most people can keep working or going to school.
- Ask about changes that help, like extra breaks or a flexible schedule. Workers may be covered by the ADA. Students may get a 504 plan.
Children, pregnancy, and older adults
- Babies: Fissures are a common cause of blood in baby stool.
Pregnancy and breastfeeding
- If you're pregnant or planning to be, tell your prenatal provider about this condition.
- Don't start or stop any medicine on your own. Some are safe in pregnancy and some need to be changed.
- Ask before taking any pain reliever. The FDA advises avoiding ibuprofen and naproxen after 20 weeks unless your doctor says to.
- Breastfeeding: Most medicines are fine, but ask. The NIH LactMed database lists what's known about each one.
For caregivers
- Go to visits when you can and take notes.
- Keep a list of medicines, allergies, and doctors in one place.
- Learn the warning signs that need fast care.
- Take breaks and ask for help. Caregivers need care too.
Outlook
Most heal without surgery.
Getting ready for your visit
Bring a list of your symptoms and medicines.
Questions to ask
- Do I need a colonoscopy?
