Pathology
Pathology refers to the deviations from a healthy system, thereby characterizing a disease state. Just like any physiological system in the body, the
endocannabinoid system (ECS) can be dysregulated as well. As a system that tries to keep a balance in the body, this dysregulation is typically caused by other pathological changes in the body. In addition, there are theories which suggest the ECS dysregulation could also be the cause of such changes.
ECS dysregulation due to pathology
The endocannabinoid system (ECS) is responsible for maintaining homeostasis in the body. It has been shown that changes in the ECS are evident in various disease states, such as Parkinson’s disease, depression, anxiety, post-traumatic stress disorder (PTSD), amyotrophic lateral sclerosis (ALS), and others.
1, 2, 3, 4, 5 By up- or down-regulating the system, for example by producing more
endocannabinoids, the ECS tries to compensate for dysregulations of endocannabinoid system in pathology. Targeting a dysregulated ECS might help symptom treatment. However, in those cases, it should not be expected to cure the underlying pathological disorder.
ECS dysregulation as a source of pathology
Some scientists argue that an intrinsic dysregulation of the endocannabinoid system (ECS) can be the cause of pathology in humans.
6, 7 According to them, these patients need to use cannabis products to bring their ECS back to the levels that are considered normal in healthy people. They concur that the symptoms can include migraines, fibromyalgia, irritable bowel syndrome, autism spectrum disorder.
6, 7 For example, a study in humans has found that the ECS is associated with serotonin release from platelets in patients that suffer from
migraines, but not when they are headache-free.
8 With regards to the
irritable bowel syndrome, Izzo and colleagues were able to show that a lower CB
1-receptor concentration lead to decreased gastrointestinal motility, leading to constipation in mice.
9 However, to confirm the hypothesis, further studies need to be done in humans. It is important to note that some cannabis-based product users that suffer from effects such headaches or
sleep problems, after quitting the products (for example, when they go on vacation to a place where they cannot bring their cannabis products), claim that their products help them with their naturally low ECS tone. In many cases, however, these people suffer from a dependence or an addiction to the products. Always consult a medical professional for information on this topic.
