This month is Irritable Bowel Syndrome Awareness Month.

IBS affects between 6–18% of people worldwide and is also known as spastic colon, irritable colon, mucous colitis, and spastic colitis. IBD is an inflammatory bowel disease which is a different condition. IBS is a conglomeration of symptoms that occur together pain in the abdomen, bloating and excess gas, mucus in the stool diarrhoea and constipation. IBS sufferers report differing severity and duration of the symptoms. However, it’s understood that the symptoms last at least 3 months for at least 3 days per month. In particularly severe cases, IBS can cause intestinal damage, but this is uncommon.

What causes IBS?

The cause of IBS isn’t currently well understood, and diagnoses are often based on symptoms. Some believe that diet, poor sleep, hormones, stress and changes in gut bacteria may all trigger symptoms. Unfortunately, diet affects everyone differently which makes it challenging to understand the triggers for each patient.

Other causes may be abnormalities in the gut flora (bacteria), severe gastrointestinal infections, and increased inflammation or overactive immune response in the digestive organs.

Another cause may be abnormalities in the digestive system nerve function which causes poorly coordinated signals between the brain and intestines.

What are the treatment options?

Treatment options for IBS include diet changes, management of lifestyle and stress, medication and counselling.

More than 50% of IBS sufferers report fatigue. IBS is related to insomnia – difficulty falling asleep, difficulty staying asleep and reporting of poor sleep quality.

One study found that the intensity of their IBS symptoms predicted the severity of fatigue  (

Another study found that poor sleep predicted more severe IBS symptoms the following day (

IBS Case Study

To start this month, we’ve prepared an IBS case study for you.

Betty Boop (not her real name), is a 32-year-old woman, who suffers from IBS. Her symptoms are chronic abdominal pain, diarrhoea, mucus and bloating. She was diagnosed with IBS on April 2017. She’d trialled multiple medications but found limited positive effects. She was also seen by a specialist and a dietician but was given little assistance besides dietary advice. She refused opioids due to her concern about addiction.

Betty obtained a referral from her GP and consulted with our Doctors and was approved for Medical Cannabis. Since then, her symptoms have improved. She has less bloating, less diarrhoea and her mood has improved.  Her pain is still present but is manageable. She’s combining Medical Cannabis therapy with a healthy diet to improve her symptoms also. Betty suffered no side effects from Medical Cannabis which is great, but this isn’t the case for everyone.


It’s important to note that Medical Marijuana may not work for everyone and that the potential side effects one may experience from Medical Cannabis may be:


CBD has a narrow side effect profile. Some reported side effects of Cannabidiol include dry mouth, low blood pressure, light-headedness, and drowsiness, however, these are very uncommon.

Patients with autoimmune disorders or those who suffer from a lot of allergies could have a negative response from carrier oil or capsule container. In those cases, CBD Isolate (which is 99% pure CBD) would be a better form to try CBD.

Signs of liver injury have also been reported in some patients, but this is very uncommon.

Side effects from CBD are very uncommon but they might include dry mouth, nausea or even allergy to the carrier oil in the CBD. We also look for other interactions with other medications, most commonly the P450 metabolism medications.


THC is a psychotropic Cannabinoid and the side effects include increased heart rate, dizziness, drowsiness, impaired short-term memory, dry mouth, nausea, anxiety, increased appetite and euphoria.

Disclaimer: This is not an inducement to use Medicinal Cannabis. Medical Cannabis doesn’t work for everyone, and it may not work for you. How Cannabis affects a person depends on many things, including their size, weight, age and health, dosage and tolerance and the results can vary. Some people may experience side effects when taking Cannabinoid medication.
