Although research on the efficacy of thyroid disorders is in its infancy, current studies regarding CBD’s influence on hormonal activity is promising.
CBD can also temporarily lower blood pressure, allowing the user to take deeper breaths. This, in turn, can have a positive effect on our physical response to stress (6).
As mentioned, the ECS is involved in regulating a wide range of critical functions, including the performance of the thyroid.
Does CBD Oil Help with Inflammation in Thyroid?
CBD is known to regulate metabolism through its interaction with the ECS. One positive effect worth mentioning is CBD’s ability to promote the fat browning effect.
In other words, CBD regulates our sleep-wake cycle. Taking lower doses in the morning may not only reduce anxiety but also improve focus and productivity (7). With heightened daily alertness throughout the day, our body starts to receive signals that it has done enough work for the day and it’s time to go to bed. Consistent supplementation with CBD can help the body manage its melatonin levels, which is a hormone that helps the body set the right gears in motion to fall asleep faster
The second scenario is more negative because it entails the risk of experiencing the second-hand side effects that don’t result from CBD alone but rather from the above interaction.
A 2015 study found significant concentrations of CB1 and CB2 cannabinoid receptors in the thyroid glands. These receptors were associated with the shrinkage of thyroid tumors, showing promise as potential blockers of the spread of malignant cells on the gland (1).
Certain nutrients are needed to make thyroid hormones, such as iodine, selenium, and zinc. A deficiency in any of these can impair proper thyroid hormone synthesis.
A clinical study looked at the role of the endocannabinoid system in thyroid tumors. They found an association between CB1 and CB2 receptors and tumor malignancy, meaning how likely a tumor is to spread and become dangerous. The study found that both of these receptors influenced thyroid tumors and believed they could both be a target of future therapies.
The thyroid is sensitive to nutrient deficiencies such as zinc, iodine, and selenium, as well as environmental pollutants which can cause it to over function (hyperthyroid), or under function (hypothyroid). In addition, the immune system can also begin attacking the thyroid gland, resulting in autoimmune thyroid conditions–Hashimoto’s thyroiditis and Grave’s Disease.
Hyperthyroidism can be caused by a few different circumstances, including autoimmunity where the immune system attacks the thyroid (known as Grave’s Disease), inflammation of the thyroid (Thyroiditis), as well as tumors that secrete excess thyroid hormones.
Other causes include treatment for hyperthyroidism which can result in diminished thyroid hormone output. Also, medications like Lithium for mental health conditions can lead to hypothyroidism.
These treatments include radioactive iodine and antithyroid drugs like methimazole and propylthiouracil (PTU). While effective, these drugs can cause severe side effects in the liver and immune system.
Doctors, scientists, and medical researchers are looking into CBD as an alternative treatment. More research is necessary to come to any definitive medical conclusions.
Conventional Thyroid Disorder Treatments (Not CBD)
The American Thyroid Association (ATA) estimates that thyroid disorders currently affect up to 20 million Americans. Furthermore, as much as 12% of the U.S. population will at some point in their lives develop a thyroid condition.
The three most common thyroid conditions are nodules, hypothyroidism, and hyperthyroidism. The causes of thyroid disorders are largely unknown. Researchers believe that autoimmune conditions, stress, high cholesterol, and smoking can be factors.
They are not recommended outside the most necessary of circumstances. Surgery can also be a common treatment method. Surgery may address lumps and masses that occur due to cancers or thyroid nodules.
