Stomach Pain

Medical Cannabis and Stomach Pain

Stomach pain is uncomfortable and, depending on intensity, can have debilitating effects on day-to-day life. It’s often caused by something as simple as trapped wind or indigestion, but it could also be a symptom of something more serious. It's important to note that sudden and severe stomach pain requires urgent medical attention.

Stomach pain is uncomfortable and, depending on intensity, can have debilitating effects on day-to-day life. It’s often caused by something as simple as trapped wind or indigestion, but it could also be a symptom of something more serious. It's important to note that sudden and severe stomach pain requires urgent medical attention.

Long-term and recurring stomach pain, sometimes referred to as chronic stomach pain, is often caused by gastrointestinal conditions including irritable bowel syndrome, Crohn’s disease, ulcerative colitis or coeliac disease. IBS pain often feels like cramping and is sometimes relieved after a bowel movement. Crohn’s disease and ulcerative colitis pain also feels like cramping but is usually more severe and can be associated with other symptoms like blood in the stool, while coeliac disease pain is usually felt in the abdomen after ingesting gluten. 

However, gastroenterological issues aren’t always to blame for stomach pain; it can also be explained by endometriosis. The pain that comes with endometriosis is often felt in the abdomen or pelvis. It’s sometimes likened to period cramps, but it’s usually much more intense; it’s sometimes experienced as stabbing, sharp and throbbing. Unlike standard period pain, endometriosis pain can be felt at any stage of the menstrual cycle.

Certain studies have suggested that medical cannabis might be able to ease stomach pain among patients with these conditions. This is possibly due to the way THC interacts with the endocannabinoid system to activate receptors that help to dull pain and slow the gut down to reduce cramping. While scientific evidence is currently limited, CBD’s potential pain-relieving properties may also be able to help ease stomach pain in some patients.

  1. Yes, patients legally prescribed medical cannabis in the UK can drive, provided that they:

    • Are not impaired in any way
    • Can prove that the cannabis medication has been legally prescribed
    • Are taking their prescribed cannabis medication as directed by your specialist consultant 

    The Cannabis Industry Council (CIC) states that as long as the above criteria are met, legally prescribed medical cannabis patients have a legal defence, even if they have over 2μg/L of THC in their blood and are subsequently arrested/charged.
    That said, it is the patient’s responsibility to judge whether they are fit to drive before getting behind the wheel.

Learn more about stomach pain and medical cannabis

What causes long term stomach pain?

Stomach pain that persists or recurs regularly can sometimes be explained by chronic gastroenterological conditions such as irritable bowel syndrome, Crohn’s disease, ulcerative colitis or coeliac disease. However, it could also be explained by gynaecological issues including endometriosis, which is sometimes misdiagnosed as IBS due to its similar symptoms.

It’s important to note that stomach pain with no clear cause should be investigated by a medical professional. Sudden, acute stomach pain could be a medical emergency. 

Can medical cannabis help with stomach pain?

There is promising evidence to suggest that medical cannabis could help some patients manage stomach pain. This is most likely due to the cannabinoid receptors in the gut’s nervous system, which medical cannabis can activate to dampen pain signalling and reduce gut motility. A reduction of gut motility could reduce the painful stomach cramps that accompany diarrhoea in IBS, coeliac disease and endometriosis patients. 

What’s more, both THC and CBD (the active compounds in medical cannabis) have been shown to have anti-inflammatory properties that could help patients with Crohn’s disease and ulcerative colitis manage stomach pain, which is often driven by inflammation of the intestine. 

Stomach pain and IBS

Irritable bowel syndrome is incredibly common, with 10-20% of adults thought to be affected. The exact cause of IBS is still unclear and can differ between patients, but doctors believe it’s usually caused by a malfunction in the brain-gut axis. The brain and the gut usually communicate very closely but this communication doesn’t always work properly for IBS patients, making their gut very sensitive. IBS can also be triggered by a stomach bug or infection, which can make nerves in the gut more sensitive. 

Along with constipation and diarrhoea, stomach pain is a major symptom of this condition. IBS stomach pain is usually described as cramping, and sometimes it’s worse after eating and better after a bowel movement. 

Studies suggest that medical cannabis could be a way for some patients to manage pain symptoms. This is due to the potential way in which THC might suppress pain signalling and slow stomach cramps in some patients. 

Medical cannabis could also help patients manage other IBS symptoms, including nausea and sleep issues. Nausea is a common IBS symptom and studies have shown that medical cannabis can provide relief from sickness and nausea for some patients as it potentially interacts with the endocannabinoid system in a way that activates receptors in the brain that can ‘switch off’ feelings of nausea. 

Stomach pain and endometriosis

Stomach and pelvic pain is a key marker of endometriosis, which affects around one and a half million people in the UK. Endometriosis happens when tissue similar to the uterine lining starts growing outside the uterus – most commonly on the fallopian tubes, ovaries, pelvic lining, bladder or bowel. The inflammation and irritation caused by this can be very painful and, when endometriosis grows on the bowel, it can trigger gut symptoms that mirror IBS. 

Additionally, the inflammation can lead to adhesion and scarring, which can create painful stabbing sensations during digestion if the bowel is affected. As well as the stomach pain of endometriosis itself, people who live with this condition often experience intense period cramps that impact their plans and wellbeing. 

Sleep, pain and the cycle

Stomach pain at nighttime can lead to disturbed sleep and insomnia, which medical cannabis may be able to provide some relief from for certain patients. There are cannabinoid receptors that help regulate sleep cycles and the THC in medical cannabis is thought to interact with these in a way that creates a sedative effect, leading to easier and longer sleep. There’s less evidence about CBD and sleep, but some studies suggest that it can ease symptoms of anxiety in a way that allows for more peaceful sleep.

When to speak to your doctor

Mild stomach pain shouldn’t usually cause alarm, but it’s important to seek medical attention if you experience severe stomach pain, blood in your stools or a change in bowel habit, unintended weight loss or vomiting that won’t stop.

6. FAQs

Is medical cannabis prescribed for IBS?

In some cases, medical cannabis is prescribed for IBS. However, every patient is assessed individually by a certified clinician. Eligible patients can only be prescribed medical cannabis if they’ve tried two traditional ways to manage symptoms first. 

Which cannabinoids affect the digestive system?

THC and CBD are both thought to affect the digestive system, but in different ways. THC works to slow down the digestive tract, which can sometimes reduce diarrhoea and stomach cramps. CBD has anti-inflammatory properties, which may be able to reduce inflammation and pain in the gut. Overall, THC’s effects on the digestive system are more well founded and thought to be more potent.

Can cannabis cause stomach pain?

In a very small number of cases, yes. It can happen when someone develops Cannabinoid hyperemesis syndrome, a medical condition caused by long-term and heavy cannabis consumption. Its main symptoms are nausea, vomiting and stomach pain. However this condition is relatively rare and following your clinician’s dosing advice should help prevent it.
