One of 80-100 cannabinoids found in the cannabis plant, there’s a lot more scientific evidence to support the benefits of CBD than many of the others, including support for pain relief, helping to relieve symptoms of anxiety, depression, epilepsy, and more. 

While CBD has been scientifically proven to offer a range of benefits and generally reacts well with the body, some reported side effects still exist, ranging from dry mouth to nausea. One of the less commonly reported side effects of CBD is constipation. Here’s the scoop on why CBD may cause constipation and what to do if it happens to you. 

Can CBD Cause Constipation?

Constipation is a common gastrointestinal issue, which usually presents as the inability to have a bowel movement. A number of everyday causes of constipation include lack of fiber in the diet, dehydration, lack of exercise, and even travel. CBD is a lesser-known cause of constipation. The main reasons people become constipated after consuming CBD are:

• Changes in gastrointestinal motility.
• Effects on gut microbiota.
• Influence on fluid absorption in the intestines.

One scientific study determined cannabinoids may cause “chronic constipation or symptoms associated with delayed gastric emptying.” In contrast, another study found “the safety and efficacy of CBD for several therapeutic applications, including seizure disorders, inflammatory responses, and upper gastrointestinal dysfunction.” 

These contrasting studies suggest that CBD may have positive effects on constipation for some subjects, while others may find it exacerbates the symptoms of constipation. 

CBD and Digestive Health

One of the main functions of the endocannabinoid system is to help regulate gastrointestinal health by preventing inflammation, maintaining the gut barrier, and more. CBD interacts with gastrointestinal motility or the movement of food from the mouth through the body.

CBD interacts directly with the CB1 receptor, part of the endocannabinoid system in the body. While THC activates these receptors, CBD alters how they work and can bring a better balance to the gut.

CBD also interacts with the CB2 receptor to reduce inflammation and other receptors to reduce symptoms of nausea. CBD has been shown in studies to help improve the symptoms of IBS and intestinal motility, but further tests are needed with specific quantities and strains to determine the best route to alleviate symptoms. 

CBD and Constipation - Anecdotal Evidence

Scientific studies can be more reliable than anecdotal evidence but are less readily available. There is mounting evidence that the way you consume CBD may be the reason you are constipated rather than the CBD itself.

CBD in tinctures is usually available in a carrier oil such as MCT oil. This oil has caused consumers to have adverse effects in the gastrointestinal region because lauric acid in the oil is often removed, and then infused.

Another common way to consume CBD is in edibles like gummies. Like tinctures, the other ingredients in these gummies could be what is causing issues in the gastrointestinal system. 

Managing Constipation Related to CBD Use

If you think CBD is causing constipation but also see its value, there are a number of things you can do before ditching your dosage. First, lower the amount of CBD you consume and switch the method of consumption.

It’s also important to look at your other lifestyle choices. Incorporate more fiber into your diet, stay hydrated, and exercise more to see if your constipation decreases. Don’t forget to consult a healthcare professional before you make significant lifestyle changes. 

Conclusion

CBD has the potential to cause constipation through changes in gastrointestinal motility, effects on gut microbiota, and influence fluid absorption in the intestines.

While CBD is not commonly associated with constipation, there is both anecdotal and scientific evidence that suggests it may cause it in some people.

Everybody’s guts differ, so be sure to “follow your gut” before making any changes and consult a medical professional if symptoms worsen.
