Reviewed by: HU Medical Review Board | Last reviewed: May 2024 | Last updated: May 2024

There is no specific test for irritable bowel syndrome (IBS). It is an illness based on symptoms. The goal of treatment is to manage those symptoms.1

Keeping a written record of your symptoms can help you better understand your illness. This record is sometimes called a symptom diary. A symptom diary should include information about your pain level and bowel movements.2,3

The diary can also keep track of other important information. You can track how different factors affect your IBS. These factors may include:2

A symptom diary can help you figure out what might be triggering your IBS. With data from the diary, you and your doctor can work together to figure out the best treatment options for you.1-3

A detailed diary is most effective

To get the full picture of your IBS symptoms, fill out the diary for 2 to 4 weeks. You can use a notebook, journal, or printable diary.2

    • Sausage-shaped
    • Soft blobs
    • Watery stool
    • Diarrhea

    • Rectal pain (sharp, dull, burning, a cramping feeling, or feeling like there is a hard object in your rectum)
  • Medicines (including dosage)
    • Prescriptions
    • Over-the-counter drugs
    • Supplements
    • Herbs

Food and drinks

  • Food
    • Fruits and vegetables
    • Meat, fish, and poultry
    • Dairy products
    • Bread and pasta
    • Desserts
    • Spices
    • Condiments
  • Drinks
    • Drinks with or without caffeine
    • Zero-sugar drinks
    • Fruit juice
    • Soda or seltzer
    • Alcohol

Emotional state

Note whether you are feeling any of the following:

  • Happy
  • Sad
  • Relaxed
  • Depressed
  • Anxious
  • Tired (physically or emotionally)


Include how long you did any of the following activities:

  • Walking
  • Running
  • Biking
  • Swimming
  • Other aerobic exercise

The diary should be as detailed as possible. Since diet is a major factor in IBS, make sure to write down exactly what you ate. Instead of simply saying you had chicken, for example, write down whether it was baked, grilled, or fried. And don't forget to include drinks and snacks. This could help you figure out dietary triggers for your IBS.1-3

Write down what you were doing that day, too. Stress can worsen IBS symptoms, so make note of whether you had a rough day. You can't eliminate all the stress in your life. But you may be able to find techniques to deal with those daily challenges. Both CBT and meditation have been proven to help with IBS symptoms.2,3,7,8

Looking for patterns

After you keep a symptom diary for 2 to 4 weeks, begin to look for patterns. Did certain foods or drinks make your symptoms worse? Did your symptoms flare when you were anxious or stressed out?2,3

Pay particular attention to the bad days. What factors do they have in common? You can discuss what you have discovered at your next doctor's appointment. Together you can decide what changes might be made to your treatment plan.2,3
