Can CBD Oil Cause Diarrhoea?

Key Takeaways

  • CBD is known to alter gut motility, but any such impact is mild; thus, it is not likely to cause diarrhoea.
  • CBD oil may cause diarrhoea only in some susceptible individuals, and such incidences are rare.

CBD can influence various body functions. It is known to alter gut motility. However, its impact on gut motility is often unpredictable. Hence, it is right to ask, “Can CBD oil cause diarrhoea?”

Well, there is good news: diarrhoea is not a common CBD side effect. This means that CBD oil diarrhoea is a rare issue.

In my medical practice, there are almost no reports of diarrhoea due to a legal CBD oil. Here, I will explain the chance of gut issues due to CBD oil, if any.

Studies confirm that the endocannabinoid system (ECS) can influence gut motility, and CBD affects ECS. However, its effects vary among individuals. Thus, in some, it may reduce motility, while in others, it may increase.(1)

Further, one must understand that diarrhoea may occur for various other reasons. For example, poor-quality products are more likely to cause such side effects due to higher levels of impurities or a lower-quality CBD extract.

Yet, another rare cause could be allergy or intolerance to certain components of CBD oil. CBD oil contains terpenes and other organic compounds that are generally good for gut health. However, individual sensitivities exist.

So, when people ask, “Can CBD cause diarrhoea?” It would be right to say that though such chances are slim, there is some possibility. Such side effects are more likely to occur due to sensitivity to specific products, overdosing, or may occur in those who have earlier not used CBD.(2)

Experience shows that some people may experience specific gastrointestinal issues like nausea or even diarrhoea when they start using CBD oil. However, such events are rare, mild, and transient. In most cases, such issues would disappear within a few days of regular use as the body gets used to CBD.

However, if issues like diarrhoea persist, such an issue is more likely to occur due to certain additives in CBD oil. In such cases, it would be better to just change the brand. It is improbable that one will continue to experience such issues for a long time.

How to stop diarrhoea from CBD oil? Well, if that is mild, it is most likely a transient issue. However, if it persists, then change your brand. Do not forget that high-quality CBD products are less likely to cause such issues. Someone might rarely experience diarrhoea for long, and in such instances, one might need to discontinue using CBD oil.

CBD oil diarrhoea how long does it last? It is usually mild and barely lasts for more than a few days.

However, those starting to use must know about the side effects of CBD. Most side effects are mild nausea, dryness in the mouth, fatigue, and rarely changes in appetite or gut function.

Further, it is worth noticing that CBD oil and stomach problems are a commonly discussed topic. This is because CBD is not just safe. It is rather helpful in many stomach problems. For example, it may be good for gastroparesis. It may also help some people with heartburn. It is also one of the good natural remedies for irritable bowel syndrome (IBS).(1)

If, for some reason, your gut does not tolerate CBD oil well, there is still a way of enjoying its health benefits. Though CBD oil is one of the safest ways to enjoy it, one may also consider a CBD vape pen.

To conclude, diarrhoea is rarely a cause of concern when using CBD oil, especially when using high-quality products. On the contrary, it may have a calming effect on the brain and gut. CBD is even a good remedy for various gut issues, including IBD. Nonetheless, if diarrhoea occurs and persists, one may choose a different brand as the issue may be due to certain additives, or one may consider CBD vape pens.
