Learn about its diverse causes, which range from medical interventions to alternative therapies. Understanding the symptoms and management strategies is crucial for effectively addressing this health concern, whether in children facing growth and mental development issues or adults experiencing metabolic changes. Gain insight into navigating the complexities of factitious hypothyroidism for optimal care.
Factitious hypothyroidism is a condition characterized by abnormally low activity of the thyroid gland, resulting in a slowing of growth and mental development in children, as well as metabolic changes in adults. This condition can be caused by various factors, including medical treatments or alternative therapies. It is essential to understand the causes, symptoms, and management of factitious hypothyroidism to effectively address this health concern.
Causes of Factitious Hypothyroidism
Factitious hypothyroidism can arise due to intentional misuse or overuse of thyroid hormones or thyroid support supplements. Individuals may purposely take excessive amounts of thyroid hormone medication and/or thyroid support supplements, leading to an imbalance in thyroid function. Additionally, alternative therapies or unconventional treatments, e.g iodine, may inadvertently disrupt thyroid function, contributing to the development of hypothyroidism symptoms.
Comprehensive Guide to Factitious Hypothyroidism
Factitious hypothyroidism arises from an abundance of thyroid hormones produced by the thyroid gland due to inappropriate use of thyroid medication, simulating the symptoms of hypothyroidism.
It’s pivotal for medical professionals to differentiate between authentic hyperthyroidism, non-thyroid conditions, and cases induced by medication abuse for accurate diagnosis and treatment.
Understanding Factitious Hypothyroidism
Factitious hypothyroidism, also termed factitious thyrotoxicosis, involves an individual deliberately ingesting excessive amounts of thyroid hormone medication or thyroid support supplements to reduce hypothyroidism symptoms. Factitious thyrotoxicosis (FTT) is a common form of thyroid hormone (TH) abuse involving voluntary but concealed intake of an excessive amount of Thyroid Hormone. In most cases, FTT seeks to improve body composition with a decrease in body fat and weight while maintaining apparent fitness. It is frequent in Munchausen syndrome, to attract attention for care.1Persani L, dell’Acqua M, Ioakim S, Campi I. Factitious thyrotoxicosis and thyroid hormone misuse or abuse. Ann Endocrinol (Paris). 2023 May;84(3):367-369. doi: 10.1016/j.ando.2023.03.008. Epub 2023 Mar 22. PMID: 36963754.
Motivations for factitious hypothyroidism vary and may stem from reduction of ubiquitous symptoms, weight loss goals, seeking medical attention for chronic unresolving health issues, or achieving personal aims.
It commonly manifests in individuals with Internet Influencer Munchausen syndrome by proxy or among individuals aiming for weight and fat reduction, often concealed and undetected, posing diverse health risks.
Symptoms of factitious hypothyroidism imitate genuine hypothyroidism but without typical signs like hair loss, dry skin or finger clubbing found in late stage Hypothyroidism.
Symptoms of Factitious Hypothyroidism
The symptoms of factitious hypothyroidism are similar to those of naturally occurring hypothyroidism. Patients may experience fatigue, weight gain, constipation, dry skin, hair loss, and cold intolerance. However, there are subtle differences that distinguish factitious hypothyroidism from other forms of the condition. Unlike hypothyroidism caused by thyroid gland disorders, factitious hypothyroidism typically does not present with a goiter. Additionally, the eyes do not bulge, and the skin over the shins does not thicken as observed in Graves disease, the most common type of hyperthyroidism.
Diagnosis and Management
Diagnosing factitious hypothyroidism requires a comprehensive evaluation by a healthcare professional. Laboratory tests, including thyroid function tests and imaging studies, may be conducted to assess thyroid hormone levels and detect any abnormalities in the thyroid gland. It is crucial to differentiate factitious hypothyroidism from other thyroid disorders to determine the appropriate course of treatment.
Management of factitious hypothyroidism involves addressing the underlying cause of thyroid hormone imbalance, which may not involve the thyroid. This may include discontinuing any unnecessary medications or supplements that are contributing to the condition. Healthcare providers may unknowingly prescribe thyroid hormone replacement therapy to restore normal thyroid function and alleviate symptoms, while worsening factitious hypothyroid symptoms. Additionally, patients may benefit from counseling or psychiatric intervention to address any underlying psychological factors contributing to the misuse of thyroid hormones.
Preventing Factitious Hypothyroidism
Preventing factitious hypothyroidism involves promoting awareness and education about the appropriate use of thyroid medications and supplements. In addition to the five non-thyroid conditions that cause low thyroid symptoms.
1. Hypothyroidism Secondary to Pituitary Hypofunction AKA – Hypothalamus Pituitary Thyroid axis (HPT axis)
In this pattern, the hypothalamus, which sits in the base of your brain is not getting a good sample of thyroid hormones in the blood. This is likely due to ischemia (decreased blood flow) to the brain.
In this pattern the pituitary gland, which sits at the base of your brain, is getting inaccurate supply and demand messages from the hypothalamus. Consequently, the pituitary will then send the thyroid erroneous signals about the need to produce more thyroid hormones.
There’s nothing wrong with the thyroid itself, it’s just not being told to get to work! This pattern is associated with a Vasomotor Control imbalance of the blood flow in the body. Blood vessels in the abdomen are dilated resulting in a reduced sampling of hormones by the hypothalamus. Vasomotor Control imbalances can be caused by metabolic conditions, chronic stress levels or chronic bacterial and viral infections.
As you can see, thyroid physiology is complex and unique to the individual. There’s no such thing as a magic pill for everyone, and we need to get a comprehensive diagnosis to gain insight as to why someone is struggling with the symptoms they have. I consult people all over the world via Skype and phone consultations, clinically investigating these underlying factors.
3. Thyroid Under-Conversion
This pattern has been covered in medical literature for years, but is not effectively alleviated by thyroid replacement hormones. The majority of thyroid hormone is in the form of T4, which is metabolically inactive, and has to be converted to T3 for use in the body. Most thyroid drugs are synthetic T4, which isn’t deficient in this pattern. It’s the conversion of the hormone, which takes place in the liver and GI system, that’s the problem. This pattern is common with chronic adrenal stress and elevated cortisol levels in the body.
4. Thyroid Over-Conversion
You would think that if the body produces more T3, the metabolically active form of thyroid hormone, it would be a good thing. Too much of a good thing will overwhelm your cells and cause a resistance pattern. This thyroid pattern is seen in people with elevated testosterone levels, insulin resistance, type II diabetes and in women with PCOS (Polycystic Ovarian Syndrome).
5. Thyroid Binding Globulin Elevation
Thyroid hormones, as with all hormones, get transported throughout the body on protein carriers. When these protein carriers, thyroid-binding globulins (TBG), are elevated this will cause an increase of protein bound thyroid hormones which are inactive. This pattern is common with excess estrogen levels and women using birth control pills or estrogen creams.
6. Thyroid Resistance
Similar to insulin resistance, thyroid resistance is caused by cellular inflammation, which decreases hormone communication with the cell membrane. Thyroid hormone production isn’t the problem in this pattern, and TSH will be normal but the person will have symptoms. Labs such as homocysteine and reverse T3 will give us a look at the inflammation and hormone receptor site blunting that is seen with this pattern.
Thyroid Resistance is also created if replacement of thyroid hormones is not monitored adequately. Sometimes the phrase, thyroid hormone resistance is used to identify cases where patients with autoimmune thyroid disorders respond poorly to normal doses of replacement thyroid hormone. This is thought to occur when patients have developed antibodies to thyroid hormones. The majority of patients with thyroid resistance to TSH have compensated hypothyroidism.
Misdiagnosis and Mistreatment of Low Thyroid Symptoms
Healthcare providers should communicate the potential risks associated with misusing thyroid hormones and emphasize the importance of following prescribed treatment regimens. Patients should be encouraged to seek medical advice before starting any new medications or supplements and to adhere to recommended dosages to prevent adverse effects on thyroid function.
Conclusion
Factitious hypothyroidism is a condition characterized by abnormally low thyroid activity, often resulting from intentional misuse of thyroid hormones or supplements. Recognizing the causes, symptoms, and management of this condition is essential for healthcare providers to provide effective care and support to affected individuals. By promoting awareness and education, we can work towards preventing factitious hypothyroidism and ensuring optimal thyroid health for all.
