Are you always exhausted? If so, you're not alone. Up to 72% of people with active Crohn's or colitis experience fatigue compared with 47% of those in remission (1). 

What may be causing your fatigue?

According to a recent study, the most common risk factors for fatigue included:

  • Sleep disturbances (such as nighttime bowel movements or pain)
  • Anxiety
  • Depression
  • Anemia (a condition where your red blood cells don’t carry enough oxygen to your body)

Other factors that may contribute to fatigue include:

  • Iron deficiency
  • Infections
  • Certain medications
  • Other medical conditions (such as IBS, fibromyalgia, chronic pain syndrome)
  • Malnutrition
  • Nutrient deficiencies
  • Dehydration
  • A lack of exercise


How can you feel less tired with Crohn’s/colitis?

  • Ask your doctor to check your labs regularly (download our free guide on what labs to ask for)
  • Work with a dietitian with experience treating IBD (like us!) to make sure you’re getting the right amount and type of nutrients to optimize your energy levels
  • Practice stress and anxiety management (like meditation, yoga, diaphragmatic breathing, mindfulness)
  • If you’re feeling depressed, ask your doctor or dietitian for a referral to a gut-specific therapist
  • Exercise regularly - even short, low-intensity exercise is be beneficial
  • Stay well hydrated
  • Prioritize sleep - implement sleep hygiene techniques such as setting a consistent bedtime and avoiding large meals or alcohol before bed and work with your doctor to identify the root cause of your sleep disturbances
We can help you reduce your symptoms without a restrictive diet
