Irritable Bowel Syndrome (IBS): Symptoms, Causes & Treatment

What is Irritable Bowel Syndrome (IBS)?

Irritable bowel syndrome, or IBS for short, describes the occurrence of a group of symptoms that affect the digestive tract. Usually, these symptoms include abdominal pain combined with constipation, diarrhea or alternating bouts of both. These symptoms, as well as others associated with IBS, can have a negative impact on the quality of life of those who experience them.

People diagnosed with IBS don’t have any noticeable signs of disease or damage in the digestive system. Rather, IBS is considered a functional gastrointestinal disorder, meaning that the gut and the brain aren’t communicating properly. This results in problems with the way the muscles in the colon contract, causing some of the symptoms like diarrhea and constipation (x).

Even though IBS affects many people – about 10-15% of the global adult population – researchers are still trying to understand what causes it. Women, especially those under the age of 50, are twice as likely to be affected than men (x).

While the underlying cause is still unknown, there are known factors that trigger it. These triggers differ from person to person but may include sensitivity to certain foods, stress and hormone fluctuations (x).

Irritable bowel syndrome is also referred to as mucous colitis, IBS colitis, nervous colon, spastic bowel or spastic colon.

Symptoms of Irritable Bowel Syndrome

The main symptoms of IBS include (x):

  • Unusual bowel movements, like diarrhea and/or constipation — some individuals tend to suffer either diarrhea or constipation more frequently than the other, though they can also have bouts of both
  • Changes in the color and texture of stools — sometimes the stool may change color, be loose or contain mucus
  • Abdominal aches, pains and cramps (like those caused by a menstrual cycle)
  • Gas and burping
  • Stomach bloating
  • Nausea, acid reflux or heartburn
  • Loss of appetite or feeling full easily

While the following symptoms aren’t digestive problems themselves, they’re also common in people with IBS (x). These include headaches, sexual problems such as decreased sexual desire, muscle aches, particularly in the lower back, fatigue and trouble sleeping, depression or anxiety and heart palpitations. An urgent or frequent need to urinate may also occur.

Irritable Bowel Syndrome Symptoms

Forms of Irritable Bowel Syndrome

There are three major forms of IBS (x):

IBS-C (IBS with constipation): This is characterized by stomach discomfort, pain, bloating, delayed or infrequent bowel movements or lumpy or hard stools.

IBS-D (IBS with diarrhea): There’s stomach discomfort, pain, loose or watery stools, constant bowel movements or a pressing need to use the toilet.

IBS-M (IBS with a mix of bowel habits): With IBS-M, when you have one or more abnormal bowel movements, more than ¼ of the stools are lumpy or hard or more than ¼ of the stools are watery or loose.

Unspecified IBS (IBS-U) and post-infectious IBS (PI-IBS), which occurs after a bacterial infection in the digestive tract, are two additional subcategories (x).

Causes of Irritable Bowel Syndrome

It still remains unclear what causes irritable bowl syndrome. However, factors such as genetics and prior life experiences (e.g., infection, trauma) may play a role (x).

Treatments for Irritable Bowel Syndrome


Your doctor can suggest medications to ease your IBS symptoms. For IBS with diarrhea, you may be prescribed drugs such as (x):

  • Loperamide
  • Eluxadoline (Viberzi)
  • Antibiotics like Xifaxan (Rifaximin)
  • Lotronex (Alosetron)

For IBS with constipation, your doctor may recommend drugs such as:

  • Laxatives
  • Plecanatide (Trulance)
  • Lubiprostone (Amitiza)
  • Linaclotide (Linzess)

Since IBS appears to stem from a brain-gut connection that may involve neurotransmitters like serotonin, antidepressants might help with abdominal pain (x). Antispasmodics and peppermint oil may also improve symptoms (x).


Probiotics can also help. These are live microorganisms that serve as the “good” bacteria in the gut. Probiotics can help regulate intestinal function, reduce hypersensitivity and improve the protective mucosal barrier of the gut. They also modulate immunity and reduce chronic inflammation. While probiotics may be helpful for all types of IBS, it shows particular efficacy in IBS with diarrhea. Reasonable doses (as opposed to very large doses) of a Lactobacillus and Bifidobacterium appear to provide the most advantage, according to a 2019 review of research (x).

Mental Health Therapies

Mental health therapies can also help relieve your IBS symptoms. Many techniques exist including cognitive behavior therapy, hypnotherapy and relaxation training (x). Focusing on mental health does not imply symptoms are “all in one’s head”. IBS is a physical problem that can also in part be managed through increased awareness of the stress response.

Natural Remedies for Irritable Bowel Syndrome

While medications, therapies and probiotics might help, people suffering from IBS can also take charge of their condition through natural remedies and lifestyle choices. Here are some simple lifestyle changes to consider in order to reduce the occurrence and severity of irritable bowel syndrome.

Diet Modification

Since certain foods and eating habits bring on IBS symptoms, changing your dietary habits might help. Medical professionals recommend keeping track of your diet, activity and symptoms to see if a pattern can be uncovered. Tips include:

  • Avoid large meals and eat smaller, more frequent meals — this may reduce diarrhea and cramping (x)
  • Focus on healthy, “real” food over processed food
  • Increase fiber — vegetables, fruits, legumes, nuts and other fiber-rich foods can help boost gut health (around 20 grams of fiber is recommended daily) (x)
  • Try eliminating gluten — multiple studies have revealed that eating a gluten-free diet may promote bowel function in persons with certain forms of IBS (x, x)
  • Cut out dairy products like milk and cheese (x)
  • Ditch caffeine (contained in teas, coffee and sodas) (x)
  • Reduce alcohol consumption

Improve Hydration

Your bowels will have a difficult time moving if your stool is hard and dry, so make sure to hydrate properly. Drinking eight glasses of water daily is a great start. Healthy fluids like soothing teas and coconut water contribute to this total, but dehydrating fluids like alcohol, soft drinks and coffee don’t (x).

Drinking lots of water isn’t just for preventing constipation. It’s just as vital for people with diarrhea — in fact, even more so. As every bowel movement causes significant loss of water, you have a much higher risk of dehydration.

Get Moving

Physical activity not only burns fat and builds muscle — it’s also good for your gut. Exercise helps promote gastrointestinal function and reduces stress. Even if you don’t like intense sweat sessions, gentle exercise like yoga works just as well. In fact, research shows that having two yoga sessions daily is as effective as conventional treatments when it comes to improving IBS symptoms (x).

The Bottom Line

Irritable bowel syndrome is not life-threatening, but it can definitely impair a person’s quality of life. The symptoms of IBS vary, but can include abdominal pain, gas, bloating, diarrhea and/or constipation. Experts aren’t yet exactly sure what causes it, but it likely involves more than one factor including neurotransmitters, gut bacteria, diet, hormones and stress levels.

This frustrating, long-term condition has no known cure, but can be managed through medication, therapy, dietary supplements and/or lifestyle choices. Working with your healthcare professional to develop a comprehensive plan of action can provide relief.
