Dr. Lyn Berutti, Dynamic Life Health Center

Our Dynamic Life Health Center in Southlake treats thyroid disorders. Dr. Berutti is Board Certified in Internal Medicine and has done additional extensive training in the latest advances in diagnosing and treating hormone disorders. She has seen a lot of success in treating a wide array of thyroid disorders.

Most conventional medicine approaches to thyroid problems are outdated in both their testing and their treatment protocols. As a result we see many patients who have symptoms of thyroid disorders, but they’ve been told that because their lab results are in the “normal” range, that no treatment is necessary. This can create a lot of unneeded frustration for people who really could benefit from proper thyroid treatment.

Another scenario that we often run into is with patients who have been diagnosed with thyroid disorders, but the medication they are on is not alleviating their symptoms. In most of these cases, we can prescribe a more tailored form of thyroid replacement that will relieve those symptoms and in many cases can make a world of difference. 

We screen for vitamin and mineral deficiencies which may also be preventing your thyroid from performing optimally. Additionally, we screen for Hashimoto’s, a disease that causes the body to produce antibodies against thyroid hormone production. If one is diagnosed with Hashimoto’s disease, we search for the underlying or root cause of the disease.

When lab values for thyroid fall within a normal range, it doesn’t mean the levels are optimal for the patient. Normal lab values are set as an average for the population. If you are diagnosed with hypothyroidism, it is important that your doctor replace both T4 and T3. Patients on both therapies have reported improvement in mood, memory, and physical health.

Our testing looks at all aspects of the thyroid gland including TSH levels, Free T3 Hormone, Free T4 Hormone, antibody levels, and Reverse T3 Hormone. Dr. Berutti treats Hypothyroidism, Hashimoto’s Disease, Hyperthyroidism, and Graves’ Disease. Additionally, the time that Dr. Berutti spends with her patients is much longer than other physicians. This allows better communication between doctor and patient with time to explore what all might be contributing to root causes versus just prescribing a pill to treat a symptom.

The Thyroid Gland

Thyroid disordersThe thyroid is a small butterfly-shaped gland located at the front of your neck and is sometimes referred to as “The Master Gland.” It is important for your overall health and is responsible for regulating your metabolism; it affects every single cell in your body. It is also responsible for:

  • Energy levels
  • Temperature control of your body
  • Fat breakdown
  • Hair growth of the scalp and eyebrows
  • Cholesterol levels
  • Weight
  • Fertility in women
  • Mood (decreased thyroid levels can contribute to anxiety and depression)
  • Cognitive function

Thyroid disorders

In the conventional medicine world, thyroid testing usually only addresses the TSH (thyroid stimulating hormone) and possibly the T4 hormone levels. This is an outdated system of testing and is inadequate to be able to discover exactly what is occurring within the thyroid gland. T4 is the hormone that is secreted by the thyroid gland into the bloodstream. In order to use that hormone for energy, the cells must be able to convert the T4 hormone into T3 hormone and many people’s bodies are unable to do this. Because the conventional method “standard” is to test TSH levels and T4, this problem with T3 conversion will not show up on their lab work and their thyroid will be treated incorrectly. Typically, patients are prescribed medications that mimic the T4 hormone. This does nothing to address the T3 deficiency so patients will be taking a medication that doesn’t treat their condition. In some cases, instead of the body converting the T4 hormone into T3, it converts it into Reverse T3 which only intensifies the symptoms of Hypothyroidism especially fatigue and weight gain. Dr. Berutti is well-educated on the up-to-date testing of all aspects of the thyroid gland and the appropriate treatments. Prescribing bioidentical T3 when indicated correctly treats the problem and symptom relief can be felt within just a few weeks, though with thyroid disorders it can take months before all symptoms abate.

Hypothyroidism (Under-Functioning Thyroid Gland)

Hypothyroidism is one of the most common types of thyroid disorders that we see. The thyroid gland is unable to provide enough hormone to meet the needs of the body. This can drastically slow the metabolism and cause other symptoms including:

  • Consistent fatigueThyroid disorders
  • Weight gain and/or difficulty losing weight
  • Hair loss or change in hair texture
  • Dry skin
  • Cold intolerance
  • Joint aches
  • Muscle aches and muscle cramps
  • Constipation
  • Memory loss
  • Depression
  • Abnormal menstrual cycles/infertility
  • Decreased libido

Underactive thyroid conditions have become more and more common, but because many doctors perform limited testing, many times this can go undiagnosed. 

Hashimoto’s Disease

Hashimoto’s Disease is an autoimmune disorder characterized by the body attacking the thyroid gland. It is one of the biggest contributors to Hypothyroidism (a low functioning thyroid gland) in this country. Initially, Hashimoto’s symptoms can cause swings of both too little thyroid hormone (Hypothyroidism) and too much hormone (Hyperthyroidism). Because the thyroid is constantly under attack, it reaches the point to where it can’t produce enough hormone and can eventually lead to Hypothyroidism.

Hashimoto’s Disease can be caused by deficiencies of minerals such as iodine, iron, zinc, and selenium. Other things like genetics, poor diet, and inflammation can contribute as well. Those who have other autoimmune disorders are at greater risk too. Unfortunately, many patients who have Hashimoto’s are misdiagnosed as having depression, anxiety, bipolar disorder, PMS, Chronic Fatigue syndrome, or even Fibromyalgia.

Thyroid treatment for Hashimoto’s must be done comprehensively to include nutrients such as iodine, selenium, iron, and zinc along with thyroid hormone replacement. Other hormones can be affected by Hashimoto’s such as estrogen, progesterone, and testosterone. Gluten, GMO foods, and other inflammatory foods can also worsen and contribute to Hashimoto’s. Because the majority of physicians don’t run a complete thyroid panel test, Hashimoto’s is easily missed as being a cause of Hypothyroidism, and a patient might be diagnosed and treated for Hypothyroidism, when Hashimoto’s Disease is what is actually occurring. In order to be correctly identified, a Hashimoto’s blood test should include TPO Peroxidase, Thyroid Peroxidase antibodies and Anti-thyroglobulin antibodies. These elevated antibodies would indicate a Hashimoto’s diagnosis.


Hyperthyroidism is a thyroid disorder characterized by too much T3 and T4 hormone being secreted by the thyroid gland. It’s the complete opposite of Hypothyroidism and is less common. Symptoms can include:

  • Increased generalized anxiety and/or panic attacks
  • Rapid heart rate
  • Irritability
  • Tremors in the hands
  • Weight loss
  • Extreme thinning and loss of hair
  • Muscle aches and fatigue
  • Feeling short of breath
  • Inability to fall asleep and stay asleep
  • Excessive sweating
  • Thick patches of skin on tops of feet and shins
  • Frequent bowel movements and/or diarrhea
  • Irregular menstrual cycles
  • Infertility
  • Erectile dysfunction
  • Heat intolerance

Symptoms can be scary and can even land people in the emergency room. This type of disorder is often misdiagnosed as a cardiac disorder or an anxiety issue. Treatment for Hyperthyroidism is more complex and thus we recommend that you see an Endocrinologist for diagnosis and treatment. Once you have had treatment, if you then have hypothyroidism (low thyroid) symptoms, we may be able to help you with continuing treatment. 

Graves’ Disease

Graves’ Disease mimics a lot of the symptoms of Hyperthyroid (overactive thyroid) disorder, however, it’s cause is autoimmune in nature. Hashimoto’s Disease is also an autoimmune disease however it leads to Hypothyroidism (low thyroid) whereas Graves’ causes the opposite. Antibodies can malfunction causing the thyroid gland to imitate the pituitary gland. This causes the thyroid to not regulate and it will overproduce thyroid stimulating antibodies. This type of thyroid disorder causes some of the same symptoms as Hyperthyroidism, but can also include complications including:

  • Enlargement of the thyroid gland (goiter)
  • Heart arrhythmia or rapid heart beat
  • Osteoporosis
  • Graves’ Ophthalmopathy (bulging eyes)

Ophthalmopathy can occur because the tissue behind the eyes can become swollen and inflamed. This also can create sensitivity to light, vision changes, red eyes, and feelings of gritty eyes. Risk factors for Graves’ Disease include:

  • Women under 40 years old
  • Smoking
  • Other autoimmune disorders such as Rheumatoid Arthritis, Lupus, Type 1 Diabetes, etc.

Because Graves’ Disease is an autoimmune disorder and its symptoms are largely that of Hyperthyroidism, it’s important to have a doctor who is experienced in treating it. It often requires a comprehensive treatment plan in order to treat both the Hyperthyroidism symptoms and the autoimmune factor. Dr. Berutti can help you with this.

Starting as a New Patient

When you start with us as a new patient, you will initially need two different appointments, approximately three weeks apart. At the first appointment, Dr. Berutti will go over your reasons for seeking help, your medical history, your health goals, and all of your symptoms. This appointment will also serve to answer any additional questions you may have. After that first appointment, an individualized lab order will be drawn up based on all of the information gleaned from that first appointment.

Your labs will need to be drawn after your first appointment. The lab panel is quite comprehensive and may include other hormones, including adrenal function, cortisol levels, a complete thyroid panel, as well as vital markers such as A1C, blood sugar, cholesterol, liver and kidney function, inflammation levels among others. 

Your thyroid hormones can have an effect on your other hormones and in some cases other hormonal imbalances may occur alongside the thyroid disorder. Your endocrine system contains many hormones and glands that operate synergistically. Dr. Berutti is going to test the right things exactly tailored to your symptoms and needs. Thyroid treatment should always include the big picture. A functional medicine approach such as Dr. Berutti’s is holistic and looks for root causes of all symptoms.

At your second appointment, once the lab results are in, Dr. Berutti will go through those lab results and how these relate to your symptoms. At that time she will prescribe appropriate treatment protocols and will discuss other measures to improve your overall health.

After prescribing  your custom treatment protocol, we will want to follow up with you every three months during the first year to check progress and to make sure that your treatment is working ideally for you.  Once you are established and balanced after the first year, she will want to see you bi-annually.
