Thyroid Issues

The thyroid is the butterfly-shaped gland in your neck, and it’s part of your hormone or endocrine system. The gland has a lot to do with energy, metabolism, and body temperature. It is a crucial component of many systems and organs, including the heart, brain, liver, kidneys, digestive tract, sex hormones, and skin. The functionality of this vital gland will affect your body’s overall wellness.

Symptoms of Dysfunction

  • Cold body temperature
  • Hair loss

  • Constipation
  • Dry skin and nails
  • Infertility
  • Joint pain and swelling
  • Lethargy/sluggishness

The Importance of Checking TSH

TSH stands for thyroid stimulating hormone, and it’s the number one thyroid hormone to have checked. A TSH test is a blood test that measures this hormone. TSH levels that are too high or too low may be a sign of a problem in the gland.

The normal range on TSH can be .4 to 4.5 and varies from lab to lab. The functional range Dr. Olivia Joseph has, for example, is 1.8 to 3.0, and she likes to see a patient’s level between a 1 and a 2.

T3 and T4 Hormones

The T3 and T4 hormones come out of your thyroid gland. Triiodothyronine (T3) specifically supports brain function, heart function, and digestion, and plays a role in your metabolic rate and bone health. You can consider it the gas pedal for all the cells in your body. Thyroxine (T4) is responsible for your mood, metabolism, and body temperature, among other things.

The Two Main Types of Thyroid Disease


Hypothyroidism occurs when there is too little T3 and T4 in your system. Some symptoms associated with hypothyroidism are trouble sleeping, difficulty concentrating, weight gain, and depression. The number one cause of hypothyroidism is Hashimoto’s, an autoimmune disease that attacks the thyroid. When you have the disorder, your risk for other autoimmune diseases is higher.


Hyperthyroidism occurs when there is too much T3 and T4 in your system. Symptoms include sweating, unexpected weight loss, rapid or irregular heartbeat, and irritability, although seniors often don’t experience symptoms. Hyperthyroidism is much more dangerous and has to be caught and managed, because it can cause significant heart issues and even fatal.

How We May Help

Dr. Olivia and Dr. Anthony provide functional medicine at The Wellness Connection and can do testing (e.g. blood work) to determine if your thyroid is functioning as it should. Our doctors also check all eight thyroid markers—something most practitioners don’t do.

Our goal is to protect this gland to find out what other systems of the body are working against it. We can also order ultrasounds and work with endocrinologists to co-manage your case.
