Can Cold Laser Therapy Regenerate Thyroid Tissue?

There is controversy over whether the cells of the thyroid gland can regenerate.  Some claim that any damage to the thyroid gland is permanent, although others like myself do think it is possible for the thyroid gland to heal if the trigger has been removed.  But it does seem to depend on the patient, as while some people who are taking thyroid hormone medication are eventually able to wean off of it once the autoimmune component has been suppressed, others will need to remain on thyroid hormone even after restoring their immune system health.

There is no question that different areas of the body will heal at a different rate.  For example, the liver has a remarkable regenerative capacity after a partial hepatectomy (1).  On the other hand, as I mentioned earlier, many don’t consider the thyroid gland as being a regenerative organ.  For example, whereas the liver usually returns to close its original weight after a partial hepatectomy, after a partial thyroidectomy the thyroid gland exhibits hypertrophy and hyperplasia (2), but it doesn’t return to its original weight as the liver does.  However, hyperplasia is an increase in cell production, and so this suggests that regeneration of this gland is possible, although admittedly it’s not a quick process when compared to other parts of the body.  And it also seems to depend on how much damage takes place to the thyroid gland, as I’m not suggesting that someone who has received a partial thyroidectomy can expect complete regeneration to occur.

Even if the thyroid gland can heal on its own, if there are methods that can speed up the healing process, or cause tissue regeneration to occur when it normally wouldn’t happen on its own, then it makes sense to consider such a treatment.  Many people are familiar with the benefits of cold laser therapy with regards to helping people with musculoskeletal conditions, pain, and wound healing.  However, most people aren’t aware that cold laser therapy can potentially benefit thyroid health by helping with the regeneration of thyroid tissue.  Before specifically talking about this, it probably would be a good idea to briefly talk about how cold laser therapy works.

How Does Cold Laser Therapy Work?

Lasers were actually discovered in the 1960s, and not too long after this it was found that laser therapy can help with wound healing, pain reduction, decreased inflammation, etc.  Studies were first conducted on mice, where it was demonstrated that lasers can help to speed up wound healing.  Eventually studies were conducted on humans and it was also found that laser stimulation helped with wound healing (3) (4).  Low level light therapy involves exposing cells or tissues to low levels of red and near infrared (NIR) light (5).  It is also known as “cold laser” therapy because the power densities used are lower than those needed to produce heating of tissue (5).

Although low level laser therapy (LLLT) has been proven to help with numerous conditions, there are controversies surrounding it.  First of all, the exact biological mechanism still isn’t completely known.  In addition, a large number of parameters such as the wavelength, fluence, power density, pulse structure, and timing of the applied light must be chosen for each treatment (5). A less than optimal choice of parameters can result in reduced effectiveness of the treatment, or even a negative therapeutic outcome (5).  This is important to understand, as some studies have demonstrated that LLLT wasn’t effective for certain conditions, but the reason might have been due to an inappropriate light source and dosage.

How Can Cold Laser Therapy Help People With Thyroid Conditions?

There are a few small studies which show that using cold laser therapy can help to improve vascularization and perhaps help to regenerate the thyroid cells in some people with hypothyroidism.  One of these studies involved 43 patients with autoimmune thyroiditis who were on levothyroxine, and the results suggested that LLLT can improve thyroid parenchyma vascularization (6).  The same study showed a significant difference in the average levothyroxine dose required between those who received the treatment, and those who received a placebo treatment (6).  They not only had an improvement in thyroid function, but the group treated by LLLT also had lower TPO antibodies, although there wasn’t a change in the thyroglobulin antibodies.  Another study involving fifteen patients who had hypothyroidism caused by autoimmune thyroiditis showed that LLLT promotes the improvement of thyroid function, as patients experienced a decreased need for levothyroxine, a reduction in the TPO antibodies, and an increase in parenchymal echogenicity (7).

Of course more studies need to be conducted to show further proof of the benefits of LLLT on thyroid health, but these results seem very promising.  One important thing to keep in mind is that even if LLLT can help to regenerate the tissue of the thyroid gland, it still won’t do anything to remove the underlying cause.  For example, if someone has Hashimoto’s Thyroiditis due to an infection, which in turn caused a leaky gut, these factors need to be addressed.  And while the studies demonstrated a decrease in TPO antibodies, they didn’t help at all with elevated thyroglobulin antibodies, which also demonstrates that the cause of the condition needs to be detected and removed.

If you have Graves’ Disease then you might wonder if  LLLT can be beneficial.  Although it’s common for people with Graves’ Disease to have elevated TPO antibodies, the primary autoantibody associated with this condition is the TSH receptor antibody…specifically thyroid stimulating immunoglobulins.  There is no evidence I’m aware of which shows that LLLT can lower these antibodies.  And the TSH receptor antibodies aren’t causing damage to the thyroid gland, as they are stimulating or binding to the TSH receptors, which in turn causes the excess production of thyroid hormone.  However, if someone with Graves’ Disease also has thyroid peroxidase (TPO) antibodies then they might benefit from receiving LLLT.

Other Chronic Conditions Which Can Benefit From Cold Laser Therapy

In addition to benefiting people with thyroid conditions, cold laser therapy can potentially help with other conditions as well.

Rheumatoid arthritis.  One study I came across showed that LLLT is able to help people with both early and late stages of rheumatoid arthritis by modulating the inflammatory response (8).

Trigeminal neuralgia.  This can be a very painful condition, and studies show that laser therapy was associated with significant reduction in the intensity and frequency of pain, and therefore LLLT can be considered for the treatment of trigeminal neuralgia without any side effects (9).

Discoid lupus erythematosus.  This condition is restricted to the skin, mostly the face.  And a small study involving 16 patients with this condition showed that laser therapy helped to improve the itching, erythema, scaling, scarring, and pain (10).

Hair loss.  A few studies have shown that LLLT can help with hair loss.  One study involved LLLT in the treatment of male and female pattern hair loss, and the authors concluded that LLLT may be an effective option to treat pattern hair loss in both men and women (11).  Another small study showed that LLLT may be a promising treatment option for patients to help with hair growth, although the technology appears to work better for some people than for others (12).

Acne Vulgaris.  This is a common skin condition, and in one study involving 28 patients, two different wavelenghts of LLLT (630 and 890 nm) were used (13).  Ten weeks after treatment the acne lesions were significantly decreased in those who were treated with 630 nm, but the decrease was not significant in those treated with 890 nm (13).

Bone repair.  A number of rat studies show that LLLT can help with bone fractures by augmenting bone tissue formation (14) (15) (16).  But of course it would be nice to see some human studies demonstrating this as well.

In summary, cold laser therapy can help with wound healing, pain reduction, decrease inflammation, and can therefore potentially benefit people with different conditions such as rheumatoid arthritis, acne, bone fractures, and other conditions.  There is also the possibility that cold laser therapy can help to regenerate thyroid tissue, which of course can benefit many people with Hashimoto’s Thyroiditis.  However, larger studies need to be conducted, and it’s important to keep in mind that even if cold laser therapy can help to regenerate thyroid tissue, it won’t do anything to address the underlying cause of the condition.

    Do you have any resources on where someone with Hashimoto’s could either participate in a study on LLLT for regenerating the thyroid, or where to go to receive LLLT treatment?

      Thank you for your excellent articles.

        Hi Laura,

        Unfortunately I don’t know of any clinical trials for LLLT that are looking for participants. I’m not sure if you read my “thyroid mastermind” blog post, but in it I mentioned Dr. Kirk Gair, who focuses on LLLT and has experience using it on thyroid patients. If you are unable to see him he might know of some other doctors who use LLLT, as I think he trains other doctors how to use LLLT on people with thyroid conditions. His website is http://www.laserpainreliefinfo.com/.

    Does ‘cold laser lifht therapy’ mean infrared saunas?

  3. Mahesh says:

    Hi,

    I am 21 year old, I am from India, 2 years back i have grave discease, After RAI treatment, thyroid cells are destroyed.. Main thing is hair loss.. Any Laser therapy is helpful for me..?
    Is this treatment available in India.. Pls suggest.. I am waiting for your response.

  4. Debbie says:

    Can you give me the settings I should be using on my LLLT? I would greatly appreciate it.

  5. Theresa says:

    I have a chiropractor might be open to LLLT on my thyroid. He has never heard using it on the thyroid. Do you have more specific information and settings that I can give him.

  6. Jill says:

    I have the same question that Theresa above me has, several chiropractors in my area practice cold laser therapy however they have no technique specifically to heal the thyroid and they wouldn’t want to just stab in the dark, so a protocol to share with them would be very helpful or some source would be even better. Threreme are several chiropractors in my area practice cold laser therapy however they have no technique specifically to heal the thyroid and they wouldn’t want to just stab in the dark, so protocol to share with them would be very helpful or some source would be even better. Thank you.

  7. Jen says:

    Hi, I am interested in knowing if cold laser therapy or infrared light therapy is better to help a thyroid with nodules and autoimmune disease? I don’t see responses to the people who have submitted questions previously which would be helpful for many to learn from but perhaps you write to us individually. I look forward to your professional response to my question. Thank you much…
