Comprehensive Thyroid Management


t zone cover 5c93bcbc91bc2


After years of development and experience Dr. John Robinson and Dr. Cristina Bosch wrote ThyroZone to offer a medical solution to patients who are simply not being provided the answers they need and deserve about their thyroid and metabolism. The science based ThyroZone system surpasses the typical advice and provides unique, practical instruction that offers real results. If you or a loved one have ever experienced a thyroid condition but have always been told the test results are “normal” then this book is for you.

ThyroZone offers a revolutionary approach to thyroid disease, a disease that afflicts millions of people who are often left with no real solution to alleviate their pain and suffering. The truth is that the medical community has yet to understand the causes — or even the symptoms — of thyroid disease. This means patients have no strategy to address their disease or ways to optimize their health to provide any meaningful quality of living. Drs. Robinson & Romero-Bosch address the solutions in their book ThyroZone. They bring their passion for healthy living and graceful aging to their patients every day at the Hormone Zone.

Low Thyroid: Hypothyroidism

This is the medical condition associated with a slow metabolic rate due to inactivity of the thyroid gland. It is very common condition, particularly in women and even more common in women with perimenopause or menopause. But men suffer from this condition also.

Do You Have Symptoms of Low Thyroid?

  • Fatigue
  • Increased sensitivity to cold
  • Constipation
  • Dry skin
  • Unexplained weight gain
  • Puffy face
  • Muscle weakness
  • Elevated blood cholesterol level
  • Muscle aches and pain
  • Pain, stiffness or swelling in your joints
  • Heavier than normal or irregular menstrual periods
  • Thinning hair
  • Slower heart rate
  • Depressed mood
  • Impaired memory

High Thyroid: Hyperthyroidism

This is the medical condition associated with a very fast metabolic rate due to an over-active thyroid gland. This condition is less common but more acutely serious. This condition is more common in people who have a history of smoking.

Do You Have Symptoms of High Thyroid?

  • Appetite change (decrease or increase)
  • Difficulty sleeping (insomnia)
  • Fatigue
  • Frequent bowel movement or diarrhea
  • Heart palpitations
  • Heat intolerance
  • Increased sweating
  • Irritability
  • Light menstrual periods
  • Mental disturbances
  • Muscle weakness
  • Nervousness
  • Shortness of breath
  • Tremor/shakiness
  • Vision changes
  • Weight loss-but perhaps weight gain
  • Thinning of hair
  • Possible increase in blood sugar

Autoimmune Thyroid Disease

This is the medical condition associated with a very fast metabolic rate due to an over-active thyroid gland. This condition is less common but more acutely serious. This condition is more common in people who have a history of smoking.

Hashimoto’s Thyroiditis

This is the condition where the immune system attacks the thyroid leading to destruction of thyroid tissue and resultant hypothyroidism (low thyroid).

Do You Have Symptoms of Hashimoto’s? Same Symptoms of Hypothyroidism Plus:

  • Goiter (swollen and enlarged thyroid)
  • Tongue swelling
  • Voice changes and hoarseness

Grave’s Disease

This is the condition where the immune system attacks the thyroid leading to dysfunction of thyroid tissue and resultant hyperthyroidism (high thyroid).

Do You Have Symptoms of Grave’s? Same Symptoms of Hyperthyroidism Plus:

  • Bulging eyes (exopthalmos)
  • Goiter (swollen and enlarged thyroid)
  • Pretibial myxedema (swelling of the skin on the shin)

The Thyrozone™ System

In Depth Medical History

The ThyroZone™ system employs the most comprehensive medical questionnaires available. Your symptoms matter to us. How you are feeling matters. Listening will be the foundation upon which we build our medical relationships and your diagnosis.

Thyroflex™ by Nitek

Reflex speed is one of the physical tests used to determine metabolic rate and therefore thyroid function. This type of assessment has been used by physicians for decades. The ThyroFlex™ machine provides an instant measurement of your reflexes and helps to determine the need for thyroid hormone balance and optimization.

Resting Metabolic Rate Analysis With Reevue by Korr

Historically, thyroid disease was diagnosed using a resting metabolic assessment, or RMR. Specifically, this is known as indirect calorimetry. For decades, physicians utilized this type of test to measure metabolic rate and therefore thyroid hormone function, but it went out of popularity when laboratory blood analysis started to dominate the medical landscape and specifically thyroid treatment. The ThyroZone™ system makes this technical machine available to patients for accurate diagnosis and monitoring, beyond the simplistic and singular view of blood analysis.

Comprehensive Lab Analysis

One of the largest problems in the medical world of thyroidology is the poor interpretation of thyroid hormone blood analysis labs. Either not enough labs are drawn or when they are drawn, they are poorly interpreted, leaving patients usually under-diagnosed and under-treated.

The ThyroZone™ system directly answers this problem with not only additional labs that are usually not considered, but a unique medical interpretation of the values using a comprehensive view and optimization goal.

The typical thyroid labs ordered for the ThyroZone™ system are:

  • TSH (Thyroid Stimulating Hormone)
  • Total & Free T4
  • Total & Free T3
  • Reverse T3
  • Anti-TPO (anti-thyroid peroxidase antibody)
  • Anti-TG (anti-thyroglobulin antibody)
  • TSI (thyrotropin stimulating immunoglobins)

Optimization of Your Thyroid Hormone Prescription and Dose

In Depth Medical History

The ThyroZone™ system is dedicated to utilizing the most effective form of thyroid hormone for the individual patient. This is usually the prescription medication known as Natural Desiccated Thyroid Hormone (NDT). Common forms of this prescription are Nature Throid (r) and Armour (r) thyroid. The key to optimal thyroid hormone choice is a medication that contains the active thyroid hormone, T3. NDT contains this vitally important hormone. Prescriptions such as Synthroid (r), Levoxyl (r), and levothyroxine are T4 only therapy and do not contain the all-important T3, and patients normally suffer as a result. But again, the ThyroZone™ system is not beholden to any one type of thyroid hormone; only the one that best works for the patient in truly relieving symptoms and optimizing performance and safety.

Nutritional Thyroid Support and Optimization

The ThyroZone™ system is committed to improving the nutritional health of a patient’s thyroid gland. Thyroid hormone alone is not sufficient to bring the best possible clinical outcomes. With this understanding, you will be guided towards the best nutrients for your thyroid gland and also to optimize any thyroid hormone you may be prescribed. Thyroid hormone and proper thyroid nutrition works synergistically.

There are many nutrients important for your thyroid gland health, and the ThyroZone™ system will evaluate and consider as many as possible. Two of the most important nutrients for your thyroid are IODINE AND SELENIUM.

Ongoing Dose Monitoring for Optimization

The goal at The Hormone Zone is Patient Optimization. The ThyroZone™ system is no different. Your metabolic rate will be continually assessed, along with your subjective and objective clinical findings, with the ultimate goal of providing the best possible thyroid hormone dose and thyroid gland health. The goal is your reliefand performance, not simply what a lab value states.

Treating the Underlying Cause

The ThyroZone™ system helps to uncover the potential underlying cause of the thyroid hormone imbalance and the altered metabolism. Some of the typical reasons for a thyroid condition are:

  • Menopause or Male Low Testosterone
  • Adrenal Dysfunction & Stress
  • Insulin Resistance
  • Diet & Food Allergies
  • Environmental Toxins
  • Poor Aging

And very typically….

  • Autoimmune Thyroiditis (Hashimoto’s Thyroiditis or Grave’s Disease)

The ThyroZone™ system focuses on addressing all of the potential underlying causes of your thyroid condition. But one of the most common causes of thyroid disease is autoimmune reactions that lead to Hashimoto’s (low or hypothyroid) or Grave’s Disease (high or hyperthyroid).

An “autoimmune” reaction refers to the phenomena where your own immune system attacks your body, in this case the thyroid gland.

Removing as many of the typical causative factors to this autoimmune reaction is the key to improvement. There are also nutritional and herbal approaches to helping with this process. Additionally, one of the most cutting-edge tools the ThyroZone™ system uses is Low Dose Naltrexone (LDN), a prescription medication with virtually no down side. This is one of the most effective tools at directly addressing the autoimmune reaction in your body and has been used since the 1980’s to combat a variety of autoimmune reactions.

To hear Dr. Robinson discuss how this cutting-edge tool is helping his patients, listen to this interview with Linda Elsegood from The LDN Research Trust:

Global Optimization View of All Related Hormones

Your thyroid gland does not operate in a vacuum, away from the influences of your other hormones. The Hormone Zone strategy is to view your entire body in the context of a global comprehensive view of all your hormone systems. And the ThyroZone™ system considers this also. When your other hormones are optimized, then your thyroid is optimized.
