How to Improve Thyroid Function

Aug 23, 23 6 min

By Dr. Kenosha Gleaton, OBGYN

What Is the Thyroid?

The thyroid is a vital gland found in the front of the neck. The thyroid releases hormones that control and influence many major bodily functions, including breathing, digestion, weight, heart rate, and more. [1-2] Because the thyroid has such a large impact on the body, healthy functioning of the thyroid is extremely important. [2] It’s estimated that 20 million people in the United States have some kind of thyroid disorder. [1] Knowing what signs to look out for as well as what you can do to support thyroid function is a great way to prioritize your health and catch any problems early on. [1-2] 

Why Is Thyroid Health Important?

The thyroid is a vital gland that helps our bodies function properly. If the thyroid doesn’t produce enough hormones, produces too many hormones, or is otherwise growing or functioning in a strange manner, many different processes can be impacted. [1-2] Thyroid hormones are responsible for cardiovascular health, infant growth, concentration, metabolism, and so much more. [1-2] 

Thyroid Conditions

There are a few different conditions relating to the thyroid. When the thyroid produces too many hormones, it is known as hyperthyroidism. [1] Hypothyroidism refers to the thyroid not producing enough hormones. The thyroid can also grow in size or become enlarged, known as a goiter. [1] This can happen to the entire gland or to individual lumps in the gland. Depending on the condition, altered thyroid function may result in various symptoms and health effects.

Symptoms of Poor Thyroid Function

Symptoms can vary depending on the condition (hyperthyroidism or hypothyroidism), but some general signs or symptoms that may be tied to irregular thyroid function include [1-2]:

  • Weight fluctuations 
  • Forgetfulness
  • Dry or coarse hair, hair loss
  • Difficulty sleeping
  • Experiencing anxiety, irritability, nervousness
  • Irregular, frequent, or heavy menstrual periods (read How Does Hypothyroidism Affect Your Menstrual Cycle?
  • Fatigue
  • Muscle weakness
  • Enlarged thyroid gland
  • Vision problems
  • Sensitivity to heat or cold

If you are experiencing any new or abnormal symptoms, be sure to speak to a healthcare provider.

How to Support and Improve Thyroid Function

It’s not possible to prevent thyroid disease, however, there are some ways to reduce risk factors and improve overall health. The key to reducing risk factors for many conditions is to live a healthy and balanced lifestyle. [3] Maintaining a healthy weight, eating plenty of fruits and vegetables, and exercising regularly can improve well-being and lead to improved health outcomes. [3] Here are a few ways to prioritize a healthier lifestyle and potentially support thyroid health. 

Checking Your Thyroid At Home

Early recognition of a thyroid problem may lead to better outcomes. In some cases, you may be able to recognize a problem at home. [1] In order to check your thyroid at home, you’ll need to identify the location of your thyroid, tip your head back while looking in the mirror, and take a drink of water. Keep an eye on your thyroid as you swallow, try to look for any lumps or bumps. You may want to repeat the test a few times. You can also take hormone tests at home if you want to ensure your hormone levels are in the normal range. It’s important to note that you should always speak to a healthcare provider directly and should not rely on self-exams if you do have any suspicion or reason to believe you may have a thyroid condition. [1] 

Alter Your Diet

A large part of maintaining a healthy lifestyle is a balanced diet. Research also shows that certain nutrients can have an impact on thyroid function and hormone regulation. Increasing levels of iodine, selenium, and probiotics in your diet may have beneficial effects. [4-6] Some of these food sources include:

  • Fish and seafood
  • Dairy products
  • Pickles
  • Kombucha
  • Sourdough
  • Brown rice
  • Eggs
  • Nuts
  • Iodized salt

Additionally, cutting back on sugar and highly processed foods may improve thyroid function and regulate thyroid hormones. [7] 

Manage Your Stress

Long-term stress can be very detrimental to your health. Studies show that chronic stress can actually alter the activity of our brain and important glands, including the thyroid. [8]  If you are someone that is carrying a lot of stress at all times, you may want to speak to a healthcare provider about healthy ways to manage your stress, including therapy, physical activity, relaxing hobbies, and more.

Avoid Endocrine Disruptors

Endocrine disrupting chemicals (EDCs) are chemicals found in foods, packaging, water, personal care products, and more. [9] EDCs can be very harmful to your health and may have the ability to interfere with thyroid receptors, gland functioning, and hormone transport. [9-10] If you are hoping to reduce your exposure to endocrine disrupting chemicals, here are some tips [11]:

  • Avoid processed foods
  • Consume fresh, organic foods
  • Avoid using plastic containers, bottles, or packaging
  • Look into the ingredients used in your personal care and hygiene products
