Sleep and Irritable Bowel Syndrome

0 3 years ago

IBS symptoms, such as abdominal pain and diarrhoea, can interrupt sleep patterns and consequently cause issues sleeping.

Sleep and IBS

There is little research on the link between sleep trouble and the gastrointestinal (GI) system. However, IBS has been linked with lower sleep quality, reduced light sleep, and significant sleep disturbance.

One study reports that IBS did not show any differences in areas such as total sleep time, the time it takes to fall asleep, or the amount of sleep in each stage. However, reported sleep trouble was more common in the IBS group. Additionally, a study that compared IBS patients to those without IBS showed that self-reported sleep trouble can be an indicator of “next-day” abdominal pain, anxiety and tiredness.

Other conditions affecting sleep quality and IBS symptoms

Sleep Apnea is a sleep disorder that affects roughly 20% of the population. Sleep apnea can interrupt sleeping patterns and lessen the quality of sleep. Common symptoms include snoring, witnessing temporary episodes of not breathing at night, and waking up with a dry mouth. Researchers found that people with sleep apnea were more likely to have IBS than patients without sleep apnea. However, increasing severity of sleep apnea was not linked with IBS. These findings show the importance of following a treatment plan for diagnosed sleep apnea, and discussing symptoms with your healthcare provider to determine if testing for sleep apnea is necessary.

Mood disorders are commonly linked with IBS. Sleep trouble is a classic feature of psychiatric and mood disorders and likely play an important role in the link between sleep disturbance and IBS. Psychiatric include treatment and or conditions relating to the mind, behaviours and emotions. It is important to recognize uncontrolled psychiatric symptoms (nervousness, inability to focus, changes in mood, appetite, sleep) and discuss them with your healthcare provider.

Melatonin is a hormone produced by the brain that helps prompt sleep. A study looked at the effect of IBS patients taking melatonin supplements. This study showed that 3 mg of melatonin before bed decreased abdominal pain, but did not seem to improve sleep trouble. Another study found higher levels of melatonin in patients eating or drinking a probiotic. This research suggests that probiotics can alter the creation of melatonin through changes in gut bacteria. This can affect sleep and IBS symptoms. It is stressed that additional studies are needed as this is very early work. However, this will hopefully encourage further investigation into the link between IBS, the gut microbiome, and sleep

Tips to improve sleep:

  1. Limit daytime naps to 30 minutes
  2. Avoid stimulants such as caffeine and nicotine close to bedtime.
  3. Exercise for at least 20 minutes per day- avoid activity in the few hours before bedtime.
  4. Get exposure to natural light during the day and darkness at night
  5. Optimize your sleep area by including comfortable bedding, “white noise”, blackout curtains, and avoid the use of electronic devices.
  6. If snoring or apnea (temporarily stop breathing) are witnessed, seek medical advice for further evaluation.
  7. Discuss sleep concerns with a healthcare provider including difficulty falling asleep or staying asleep.
  8. Discuss uncontrolled mood symptoms with your healthcare provider.

Unfortunately, it is safe to say that the average healthcare provider does not necessarily ask about sleep disturbance in patients with functional bowel disorders, and patients may not mention them to their treating healthcare provider.

Be sure to let your healthcare provider know if your IBS symptoms are disturbing your sleep. Treatment for sleep disturbance will likely improve your overall quality of life.
