Introduction to Thyroid Nodules and Hair Loss

The thyroid gland is a butterfly shaped gland in the neck just below the voice box. Thyroid gland produces hormone that is required for our metabolism with under or over hormone secretion both causing physical problems. Thyroid nodules are abnormal lumps (growths) within the thyroid gland.

Thyroid nodules are common, with 8% of women and 2% of men having nodules that are large enough that they can be felt. Fortunately, many of these nodules are small and asymptomatic, but as they grow larger, they can cause  a variety of issues. Thyroid nodules can either increase or reduce the amount of thyroid hormone produced by the gland, and one of the symptoms this can cause is hair loss.

Thyroid Nodules and Hormonal Imbalance: How They Affect Hair Health

Hair loss can be a result of both an overactive thyroid and an underactive one. “Cold” thyroid nodules produce less thyroid hormone, resulting in hypothyroidism, while “hot” nodules produce more, resulting in hyperthyroidism.

The hair loss is of a type called telogen effluvium, which is caused when your hair roots enter the resting stage of their cycle too early. Normally, each hair follicle goes through a cycle. It starts in the growth cycle, when a new hair is produced. Variations in the growth cycle caused by genetics are why some people naturally grow longer hair than others. After a few years, the follicle takes a break, and other follicles take over. The hair eventually falls out or sheds. Telogen effluvium means that your follicles go into resting stage too early, meaning your hair falls out prematurely and is less likely to be replaced.


Recognizing Hair Loss as a Symptom of Thyroid Nodules

Hair loss caused by thyroid issues is typically diffuse. It affects the entire scalp, and can also affect other parts of the body, such as the underarm area or, in men, the face. Body and facial hair loss, however, may not be noticed by individuals who routinely shave.

The hair loss can be dramatic, however, with hair coming out in chunks. Hair loss warrants a check of thyroid levels and a check for nodules if it is accompanied by other thyroid symptoms, such as weight gain or loss, fatigue, or changes in sleep patterns.


Treatment Approaches: Addressing Thyroid Nodules to Improve Hair Growth

The good news about telogen effluvium is that while it is dramatic, it is also temporary. The hair cycle returns to normal and hair grows back, although this can take some time, once the thyroid imbalance has been addressed.

Thyroid nodules that are not causing symptoms are generally not treated. When they are, a common treatment is radiofrequency ablation to shrink the size of the nodules. This is typically recommended for nodules that are large enough to be felt and may be causing problems like pain when swallowing. You may also receive medication – either levothyroxine to supplement underproduction of thyroid hormone or antithyroid medication to reduce hormone production (note that these medications can sometimes cause hair loss as a side effect).

Once hormone levels are back to normal, hair regrowth will resume. However, it can take several months. Also, hair loss can sometimes occur after treatment has started because it takes several months to show up as a symptom. This is normal and should not be a sign to stop treatment.


Lifestyle Modifications: Supporting Hair Health Alongside Treatment

Hair loss is cosmetic, but can have significant effects on your self esteem and mental health, not to mention being obvious to those around you. Some thyroid patients may choose to wear a wig in public until their hair recovers.

You should support your hair’s recovery alongside treatment for your thyroid by eating a balanced diet and including foods and supplements to encourage hair growth. Look for foods rich in omega-3 such as soy and tofu, or a flaxseed oil supplement. If you don’t eat meat, consider supplementing vitamin B12, and add foods containing B6 such as bananasb and potatoes. Take a daily vitamin, and make sure it contains biotin, which is an essential nutrient for hair and nail production. Read more about having a thyroid-healthy diet here in our other blog post. Make sure you manage stress and get enough sleep. Don’t be afraid to take steps to hide your hair loss and keep yourself looking good as worrying about your hair loss can slow regrowth.


Looking Ahead: Long-Term Care and Maintenance of Hair Health

As long as you keep your thyroid hormones in balance, your hair will grow back the way it was before. The keyis to monitor thyroid function and go to all followup appointments. If prescribed medication, take it as required. As long as you do this, the long term outlook for your hair is better. Thyroid nodules can impact thyroid function and this can, in turn, cause a form of hair loss. Treating the thyroid nodules should cause your hair to come back. However, you do need to take steps to keep your thyroid healthy.

If you have thyroid nodules and are experiencing hair loss, the Supreme Vascular and Interventional Clinic in Singpore can help.

Thyroid Nodule Radiofrequency Ablation (RFA) Treatment

Radiofrequency ablation aims to give patients a non-surgical option for treating thyroid nodules. This procedure is a minimally invasive option that a surgeon can perform, should the preliminary tests determine that you would benefit from it.

The Advantages of RFA of Thyroid Nodules
The major advantages of the technique are as below.

  1. It is done as day surgery procedure under light sedation.
  2. It takes about 45 minutes to one hour to complete the entire procedure.
  3. Patients are discharged the same day.
  4. Normal thyroid tissue adjacent to the nodule is preserved.
  5. It does not affect thyroid function.
  6. Multiple nodules can be treated at same time.
  7. The treated nodules do not regrow again.
  8. No surgical scar with needle mark on the skin.
  9. Quick recovery and back to full activity and normal lifestyle.
  10. The technique is suitable to treat even large thyroid nodules.

How to Keep Thyroid Healthy for Optimal Well-Being

As part of the endocrine system, the thyroid hormones must be perfectly balanced at all times for the body to function normally.

Caring For Your Thyroid Health

Have you ever experienced difficulty swallowing or breathing? You may have risk factors including a family history of thyroid nodules or iodine deficiency. Thyroid nodules are abnormal lumps (growths) within the thyroid gland, a butterfly-shaped gland located below your voice box. Even if most thyroid nodules are benign, 10-15% of nodules are cancerous. Sometimes overgrowth of normal thyroid tissue can lead to hyperthyroidism. In other cases, multiple nodules can form in the thyroid called multinodular goiter. Fluid filled thyroid cysts can be one type of thyroid nodule within the thyroid. More complex nodules may lead to thyroid cancers. Depending on the root cause and type of nodule you have, patients can monitor with regular ultrasound or even have a thyroid fine needle aspiration biopsy (FNAC) if required. Surgery to remove partial or whole thyroid gland can be done but thanks to minimally invasive treatments such as Radiofrequency Ablation (RFA), this procedure can treat noncancerous and cancerous thyroid lumps.
