Up to 16% of people in the United States live with irritable bowel syndrome (IBS), a condition that involves gastrointestinal issues like constipation, bloating, and diarrhea.

While sleep disturbances aren’t an official part of the IBS diagnostic criteria, research has found that roughly half of all people with IBS have sleeping difficulties, which might include:

  • insomnia
  • waking up
  • It is daytime.
  • Getting less refreshing sleep can make you feel less rested.

There are a lot of things you can do to improve your rest, even if you have an illness like Irritable Bowel Syndrome.

There is a connection between sleep and gut health, and a few tips to have a more relaxing night.

A complex communication system called the gut-brain axis connects your brain and gastrointestinal tract, or gut. This connection means gut disturbances can disrupt the parts of your nervous system that control sleep. A lack of sleep, meanwhile, can worsen IBS symptoms.

There are several theories on how sleep and irrthropsy affect each other. Many of these issues are related.


It can be hard to drift off when you feel like someone is holding your small intestine, as some people might describe their symptoms of Irritable bowel syndrome.

A 2018 survey of Dutch university students linked IBS pain to:

Constipation and diarrhea symptoms also affected these sleep variables. However, pain was by far the most influential factor. of the IBS symptoms affected total sleep time.

On the other hand, poor sleep may also cause IBS pain. A small 2014 study involving 24 women found they were more likely to have abdominal IBS pain if they reported poor sleep the night before.

“When your scuplture muscles move during digestion, your body knows that it’s normal.”

Sleep-deprived nerves can forget that fact and see peristalsis as dangerous. They send signals to your brain that cause pain when food moves through your gut.


Your intestines don’t just hold stool. They also contain your microbiome, a complex ecosystem of microbes that help your body break down food for digestion.

Disruptions to this ecosystem, called dysbiosis, can interfere with your bowel functioning. Nearly 3 in 4 people with IBS have dysbiosis, estimates 2015 research.

Animal research suggests that when your microbiome doesn’t correctly break down food, the leftover chemicals can interfere with your circadian rhythm. If your body’s internal clock is thrown off, you may have trouble falling or staying asleep.

Chronic sleep issues can disrupt your microbiome. Getting enough sleep can help restore balance to the community ofbacteria in your gut.

Autonomic system

People with IBS tend to have more inflammatory agents, such as tumor necrosis factor α (TNFα), in their gut. TNFα can inhibit the internal clock that tells organs what to do when. This may throw off your sleep schedule.

The reverse pattern is also possible. Sleep disturbances often raise your inflammation levels. Inflammation, in turn, can cause cramping, diarrhea, and constipation.

In many cases, the sleep disturbances found in IBS involve symptoms severe and persistent enough to qualify as clinical sleep disorders.

Researchers in a 2018 review analyzed 36 IBS studies with more than 63,000 total study participants.

37.6% of people with Irritable Bowel Syndrome also have a sleep disorder. If you have the condition, you are more likely to have a sleep disorder than someone without it. Children and adolescents with Irritable Bowel Syndrome are seven times more likely to have sleep disorders than the general public.

The 2018 review didn’t cover specific diagnoses, though. But a smaller 2021 survey of U.S. adults examined how often certain sleep issues appeared with IBS. After controlling for demographic variables, researchers found people with IBS were:

  • It is more likely to have insomnia symptoms.
  • 4.6 times as likely to have symptoms of hypersomnia (excessive sleepiness)
  • 5 times as likely to have insomnia and hypersomnia.

Even if you have irrthropsy, other conditions can contribute to sleep issues. This condition is often accompanied by other concerns that affect sleep.

Chronic pain

According to the 2021 survey mentioned above, 63% of people with IBS have chronic back or neck pain — in addition to any bowel pain they have from IBS.

Pain can activate your sympathetic nervous system, which tells your body to stay alert and prepare to act. Your body may divert resources from the parts of your brain in charge of sleep, which makes your sleep less restful. Severe pain may even wake you up from sleep.

Mood disorders

That 2021 survey also found that more than 1 in 4 people with IBS live with a mood disorder, including depression and bipolar disorder.

Mood disorders, also called affective disorders, can affect how your brain moves through the phases of sleep, especially REM sleep. This is why sleep issues are among the main criteria for these mental health conditions.

In fact, over 90% of people with depression experience some kind of sleep disturbance, according to a 2019 review. People living with bipolar disorder also commonly report sleep problems.


Around 37% of people with IBS also have an anxiety condition.

People living with anxiety often have higher levels of the stress hormone cortisol in their bodies. This hormone also helps you wake up in the morning.

But high nighttime levels of cortisol can make it hard to fall asleep, which helps explain why anxiety and insomnia often come hand in hand.

It is possible to improve your sleep andIBS symptoms at home with some lifestyle changes. You can try these strategies right away.

Move your body

Physical movement can help you blow off steam, which can leave you less restless at night. Exercise can also help reinforce your circadian rhythm.

You don’t have to run a marathon to wear yourself out, though. Gentle exercise like yoga or walking can improve your sleep.

A 2019 review suggests aerobic exercise may help improve IBS-related constipation, but many of the included studies had a low quality of evidence.

What’s more, exercise therapy may not work for everyone. If you experience bowel pain while working up a sweat, you may want to opt for gentler forms of exercise.

Cut back on caffeine before bed

Caffeine is a stimulant that can stay in your system for several hours. If you drink coffee or an energy drink within 6 hours of your bedtime, you may still feel wired when your head hits the pillow.

Caffeine can also rile up your intestines and may cause diarrhea, which can also keep you awake.

A 2021 study involving 3,362 Iranian adults linked drinking coffee at least once a week to a higher chance of developing IBS. People who consumed more than 106.5 milligrams (mg) of caffeine a day had a 47% greater chance of developing IBS symptoms than those who consumed less caffeine.

For reference, an 8-ounce cup of brewed coffee contains about 95 mg of caffeine on average.

Fill up on fiber

A national survey of more than 5,500 U.S. adults linked fiber intake to sleep duration.

Adults who reported “very short” sleep, or fewer than 5 hours, ate an average of 13.2 grams (g) of fiber per day. Meanwhile, adults who reported a “normal” amount of sleep, or 7 to 8 hours, ate 16.6 g of fiber per day.

Fiber can help improve the symptoms of Irritable Bowel Syndrome, since it can help stool move quickly and easily through your stomach.

Common sources of soluble fiber include:

  • Beans: black beans, lima beans, kidney beans
  • Vegetables: broccoli, carrots, Brussels sprouts
  • Fruits: pears, apricots, apples
  • Nuts and seeds: hazelnuts, sunflower seeds, flax seeds
  • Grains: oats, barley

Consider melatonin supplements

Your body produces the hormone melatonin to signal when it’s time to sleep. Some people take melatonin supplements to treat insomnia.

Research from 2014 suggests 3 mg of melatonin at bedtime may help improve abdominal pain related to IBS. Scientists theorize that melatonin affects your intestinal functioning by:

  • Making sure stool moves at an even pace.
  • Reducing inflammation in your colon is something that can be done.
  • Pain signals from the gut.

melatonin supplements are generally safe, but it is always best to ask a healthcare professional before adding melatonin supplements to your diet.

If your IBS symptoms don’t improve with lifestyle changes, or if they begin to affect your overall quality of life, you may want to visit a gastroenterologist. Getting treatment for your IBS symptoms may improve sleep and gastrointestinal issues.

Treatment usually involves a combination of changes to diet and medication. Depending on the type ofIBS you have, the specifics of your treatment plan may be different.

  • constipation subtype (IBS-C)
  • diarrhea subtype (IBS-D)
  • mixed subtype (IBS-M)

Dietary changes

Many people with IBS find the food they eat directly affects their symptoms. Any IBS treatment will most likely include a dietary component.

A survey of 1,562 U.S. gastroenterologists asked them which specialty diets they recommended in their practice:

A registered dietitian can be referred by your doctor to build a personalized nutrition plan.

The power of peppermint

Some evidence suggests peppermint supplements can also relieve IBS symptoms. Just keep in mind that supplements, or peppermint oil capsules in specific formulations, pack a lot more punch than a cup of peppermint tea.

While tea can certainly help soothe an upset stomach, you’ll generally want to opt for supplements over tea to help ease IBS symptoms. A doctor or other healthcare professional can offer more guidance on trying peppermint supplements.


OTC medications can help with occasional CSDs, but they may not be enough for persistent CSDs.

Your doctor may prescribe.


It may surprise you to learn antidepressants can also make up part of IBS treatment.

Inflammation and stress can contribute to Issitis pain. They can affect the function of the colon.

Tricyclic antidepressants (TCAs), an older class of antidepressants, can slow digestion and reduce diarrhea.

If you have constipation, your IBS care team might recommend the newer selective serotonin reuptake inhibitors (SSRIs). They can speed up your digestion, improving constipation.

In addition, antidepressants can indirectly improve sleep issues that relate to underlying anxiety or depression, whether these concerns relate to IBS symptoms or another cause.

Problems with one bodily function can cause problems with the other.

Disruption of your sleep can make you feel worse for yourIBS symptoms, and this can create a negative feedback loop.

The healing process has a different effect. Improving your sleep can help with the symptoms of the disease. You can sleep better if you treat Irritable Stool Disease.

If you have been having trouble sleeping, reaching out to a doctor or other healthcare professional is a good next step. They can help you build a treatment plan that addresses all your health needs.
