Laser Therapy for Thyroid

(Under-active / hypothyroidism)

What is Laser Therapy for Thyroid (LLLT)?

We have found Low Level Laser Therapy for Thyroid (LLLT) an effective natural health solution for the improvement of an under-active thyroid gland function (hypothyroidism), and for the relief of associated symptoms such as tiredness, muscle and joint pain, puffiness, weight gain, low mood and depression. Patients who experience the most benefit from Laser Therapy for Thyroid, do so in conjunction with maintaining a food nutrition plan recommended for Hashimoto’s Disease.

What is Hypothyroidism?

Hypothyroidism is the name given to the condition resulting from an under-active thyroid gland, which means that the thyroid is not producing enough thyroid hormone for the body’s needs. The most common cause for hypothyroidism is an autoimmune disease known as Chronic Autoimmune Thyroiditis (CAT) or ‘Hashimoto’s thyroiditis’, when the body’s immune system attacks thyroid cells as though they were foreign cells. This autoimmune dysfunction leads progressively to thyroiditis. Sometimes iodine treatment or other medical procedures for an over-active thyroid gland may also lead to hypothyroidism. Traditionally, a high incidence of hypothyroidism requires continuous treatment with levothyroxine (LT4).

Symptoms of Hypothyroidism

There are many symptoms associated with an under-active thyroid gland including fatigue and tiredness, increased awareness of the cold, dry and coarse skin, dry and thinning hair, hoarse or croaky voice, dysphagia (difficulty swallowing food), constipation, muscle weakness, cramps and aches, pins and needles in the fingers and hands (carpal tunnel syndrome), heavier and longer periods, fertility problems, low libido, weight gain, puffy face and bags under the eyes, slow speech, movements and thoughts, low mood or depression, memory problems, difficulty in concentration, slow heart beat, slightly raised blood pressure and raised cholesterol.

An under-active thyroid is typically associated with a thyroid-stimulating hormone (TSH) level above the reference range and a thyroxine (FT4) level that is below the reference range. It is reasonable to have a test for thyroid antibodies to confirm that the cause is autoimmune.

Laser Therapy for Thyroid offers patients a natural solution for addressing this condition.

Laser Therapy for Thyroid Treatment

We have developed Photobiomodulation protocols to treat Hypothyroidism in partnership with our patients over many years. We apply Infrared (IR) and Near Infrared (NIR) light wavelengths at a low power intensity, through the lymphatic system and key nerves throughout the body, without the need to apply the red light directly onto the thyroid gland itself. It is a standard medical procedure not to place any electrical device above the thyroid gland in the neck.

Many patients experience relief of their symptoms and report higher energy levels, less frequent Hashimoto’s attacks, improved digestion and weight loss after a course Laser Therapy for Thyroid treatments. Some patients experience full recovery from abnormal levels of T4 and T3, and with supervision by their prescribing doctor referring to the appropriate blood tests, they have been able to stop taking levothyroxine completely.

Some Red Light Therapy | LED products on the market have increased the power output. Class 2 lasers are limited to a maximum output power of 1 milliwatt or one-thousandth of a watt (abbreviated to mW). The NovoThor Red Light Therapy bed is a good example.

Class 1 devices cannot harm the eyes, which is why they are freely available for home use. Power output for Red Light Therapy | LED equipment is usually  can increase up 500 mW to fall within a low power laser category. We recommend a number of Class 1 home use laser devices for our patients to use in between treatments in the clinic, including the Handy Cure Laser and the B Cure Laser.

Class 3b Laser is widely used within most clinical Low Level Laser equipment used by the medical profession in the area of Photobiomodulation (PMBT). Class 3b Laser does not create a thermal effect so it does not burn, however Class 3b laser could damage the eyes if shone directly into them. Protective goggles are always worn and the treatment is administered by a professionally trained therapist.

Class 3b Laser is considered the most effective Red Light Therapy available and is employed for clinical trials and research in the Laser Therapy field. At Laser Medicine we use a variety of probes with different wavelengths and power output depending on the specific medical condition or type of treatment. Skin, as mentioned earlier, requires a different approach to for example, bone fracture repair.

Laser devices with an output power of above 500 mW can burn the skin. This kind of Laser should not be used for Low Level Laser | Photobiomodulation Therapy and is misleading if this is the manufacturer’s claim.

Hashimoto’s Low Thyroid Diet

At Laser Medicine we place a significant emphasis on nutrition and personally follow a whole food diet that leaves out sugar, processed food and chemically farmed produce. We believe that organic vegetables, grass fed meat, wild fish and good fats all combine to reduce inflammation in the body, whereas sugar, flour, processed foods and microwave meals have an inflammatory effect.

A good diet supports good health, and never more so than in the case of Hashimoto’s Disease. Many foods can trigger Hashimoto’s low thyroid flares as well as cause fatigue, rashes, joint pain, digestive issues, headaches, anxiety, depression, and more. Many people with Hashimoto’s hypothyroidism react to gluten, dairy, different grains, eggs, nuts, or nightshades. Sugar, sweeteners, and sweet fruits can also trigger autoimmune thyroid flares.

We therefore highly recommend that our patients, in conjunction with Laser Therapy for Thyroid, are mindful about their diet, and carry out the necessary research as to what works best for them. This article is a good place to start.


The benefits of Photobiomodulation Therapy (PMBT) for Hypothyroidism are supported in clinical trials, indicating both short and long term improvements in thyroid function, and affirming the positive long-term effects of Low Level Laser.
