How Your (Hypo)Thyroid(ism) Impacts Your Metabolism

Written by

Gastrointestinal Function Chronic constipation is a common complaint of people with an underactive thyroid gland. Poor thyroid function slows down the amount of time it takes for food to move through the intestines. This increases the potential of gut infections from harmful bacteria and yeast, leading to inflammation, malabsorption, and increased risk of developing food intolerances. The production of gastric acid depends on the hormone gastrin, which diminishes with hypothyroidism. This can cause digestive complaints like bloating, heartburn, gas, and infections. In people with hypothyroidism and low stomach acid, protein deficiency may occur. Thyroid hormones strongly influence the tight junctions in the stomach and small intestine, which form the impermeable barrier of the gut. “Leaky gut” (increased intestinal permeability) is a major contributor to thyroid autoimmune diseases like Hashimoto’s thyroiditis. Studies showed that T3 and T4 thyroid hormones protect gut mucosal lining from stress induced ulcer formation. Inflammation in the gut […]

Hyperthyroidism vs. Hypothyroidism: Types of Thyroid Diseases

Written by

While addressing a thyroid dysfunction, it’s essential to consider the interconnected web of other imbalances, toxicities, and nutritional deficiencies that are always at play. Your thyroid gland is like the body’s energy factory. Every cell in the body requires thyroid hormones. When it’s operating effectively, you feel energetic, healthy, and in control. But it takes the right amount of thyroid hormones, in a careful balance, for the body to function properly. Too little thyroid hormone, and the body slows down. Too much thyroid hormone, and everything speeds up. When talking about thyroid dysfunctions and thyroid diseases, most people only think of hypothyroidism, but in reality there are many more thyroid conditions that can arise. Non-Autoimmune Hyperthyroidism  It’s estimated that between 3 and 10 million people actually suffer from an overactive thyroid, or hyperthyroidism. Hyperthyroidism is a condition that occurs when the thyroid is overactive and produces too much of one or both […]

What You Need to Know About The 4 “T”s to Thyroid Testing

Written by

What is happening here? Many doctors rely only on TSH marker to diagnose and manage thyroid disease; however, this is just one of the four needed markers to establish a correct interpretation and analysis of your thyroid status. Moreover, many doctors use the lab ranges (referred to as “pathological” or disease ranges) that come with the test results, instead of functional ranges, which have been carefully researched and formulated as parameters of good thyroid health. The lab ranges are simply the averages of all the people who have had blood work analyzed by that lab in the last year. They are so called “normal” or “healthy” places to be but are actually statistical averages. Different labs can and do have different reference ranges. It is common to have a test result come back “normal” from one lab and “out of range” for another lab. In truth, if your lab values […]

5 Tips to Thrive with Your Thyroid in 2017

Written by

Why is it that when having a thyroid dysfunction, one might feel so drained and unwell all throughout the body? Because the thyroid controls the rate of energy production, maintains body temperature, regulates body weight, menstrual cycles, muscle strength, heart rate, breathing, and affects brain chemistry profoundly, influencing mood and emotions. No wonder that any dysfunctions in its activity will be intensely felt throughout the body! Regard for Healthy Food Food IS the best medicine. The way our food is grown and consumed should be based on respect, both for the food and our body. It is estimated that today only 10% of all American adults consume enough healthy foods for their diet to qualify as “good,” according to researchers at the USDA Center for Nutrition Policy and Promotion. Fortunately, there is a wealth of information today that is accessible and meant to help you find out what diet is […]

The Best Clinical Guidelines Money Can Buy: A Look at Guidelines Bias and Thyroid Treatment

Written by

The article didn’t get much attention in the American medical community, and that’s no surprise. The title of the British Medical Journal article was “Evidence Based Medicine: Why we can’t trust clinical guidelines.” In the June 2013 article, author Jeanne Lenzer describes how drug companies can negatively influence members of committees that create clinical guidelines, to the detriment of patient care. What are Clinical Guidelines? According to the Institute of Medicine, clinical practice guidelines are “statements that include recommendations intended to optimize patient care that are informed by a systematic review of evidence and an assessment of the benefits and harms of alternative care options.” Ideally, these guidelines should be based on rigorous analysis, good science, and the best possible evidence and patient outcomes, without any influence from the manufacturers of the drugs being reviewed, and procedures or medical devices involved in the treatments. In reality, however, as Lenzer identifies, […]

Weight Gain Despite Thyroid Treatment May Be Hypothalamic Obesity Disorder

Written by

The research was presented in a poster session by Saad Sakkal, MD at the May 2014 annual meeting of the American Association of Clinical Endocrinologists (AACE). Before we take a look at the research, let’s explain a bit more about the hypothalamus and its impact on weight and metabolism. What is The Hypothalamus? Your hypothalamus is an almond-sized part of the brain that connects your nervous system to your endocrine system, with your pituitary gland acting as a go-between. The job of the hypothalamus is to release hormones that then cause the pituitary gland to release (or stop releasing) pituitary hormones. This hormonal process controls the body’s temperature, hunger, thirst, fatigue, sleep cycles, and daily cyclical rhythms. Cells in the hypothalamus take up the inactive form of thyroid hormone T4 (thyroxine), and convert the T4 into the active thyroid hormone, T3 (triiodothyronine.) The T3 then stimulates the production of TSH, […]

Melatonin: For Sleep, Thyroid, Hormones and More

Written by

Melatonin is produced — primarily at night — by the pineal gland, a tiny gland located in the brain. The pineal acts as a controller of our body’s clock, including the day-to-day 24-hour clock that tells us when to sleep and when to wake. It also controls our lifetime biological clock that decides on bigger hormonal issues, such as when we enter puberty and when we enter menopause. Melatonin and Sleep Melatonin is known to be a help for sleep. Various studies have shown it to help people fall asleep more quickly, to stay asleep, have more refreshing sleep, and reduced daytime fatigue. The main side effect of melatonin is morning grogginess. If you experience this, you can drop down to a lower dose, and determine what dosage will help you sleep, without causing any morning side effects. Some research into melatonin have reported that it improves mood upon waking, […]

Is Thyroid Disease the Cause of Your Low Libido?

Written by

Studies show that even slightly reduced thyroid levels, even considered still in the “normal” range can dramatically decrease libido in women as well as causing fatigue, weight gain and depression. How Does Thyroid Dysfunction Affect Libido Hypothyroidism reveals itself in a very gradual manner. Low thyroid symptoms are very subtle and are often similar to the ones of aging. Low thyroid levels affect different parts of the body in different ways. Patients more often reporting loss of libido are those with hypothyroidism. Those with hyperthyroidism can also experience this symptom, but they can also experience episodes of increased sex drive, due to the sped up metabolism hyperthyroidism can cause. With hypothyroidism, the metabolism is slowed down, which means the reproductive organs are slowed down as well. The adrenal glands that produce hormones that convert into the sex hormones are also slowed down. Both men and women can see decreased testosterone […]

Treating Thyroid Conditions

Written by

It’s important to address the real cause of your imbalances and use the most effective combination of thyroid hormones so you can feel at your best. Everything You Need To Know About Thyroid Treatment Hypothyroidism is generally treated with synthetic T4 (Levothyroxine). Products such as Synthroid and Levoxyl are the most widely accepted forms of thyroid replacement. This is based on an assumption that the body will convert what it needs to the biologically active form T3. However, many people cannot efficiently convert T4 to T3. This is a problem because T3 is the more active form of thyroid hormone. Even if your T4 and TSH levels are optimal, if your T3 levels are imbalanced, you may still experience symptoms. A study published in the Journal of Clinical Investigation in 1995 demonstrated that the normalization of plasma TSH and T4 levels with T4-only preparations provide adequate tissue T3 levels to […]

Talking With Your Doctor About Your Thyroid Concerns

Written by

If you feel frustrated because your TSH results are “normal” and your doctor tells you there is nothing wrong, but you still experience a wide range of thyroid-related symptoms, we understand and we know why. The Reality About Thyroid Testing The TSH (Thyroid Stimulating Hormone) is the test that most doctors use to screen for hypothyroidism. But this test actually measures how well the pituitary is “talking” to the thyroid gland, rather than measuring actual thyroid hormones or, more importantly, the level of thyroid activity in the body. To date, in most clinical practices in the United States, hypothyroidism is diagnosed solely when the TSH level is consistently above the upper limit of normal of 4.0 to 5.0 ng/dL. Unfortunately, this assumption no longer holds true when we delve into the domain of thyroid function in the aging population. There’s a better way to measure your thyroid health. Comprehensive testing should […]

Thyroid and Obesity: Is There a Connection?

Written by

Increasing prevalence of overweight people is a major concern globally; and in the United States, nearly one third of adults were classified as obese at the end of the 20th century. But minimal data has been presented regarding an association between variations in thyroid function seen in the general population and body weight. The Thyroid and Body Weight Connection The thyroid provides important bodily functions. Because it stimulates the production of cellular energy, production of all other hormones will be negatively impacted when thyroid hormone levels are less than optimal. Every aspect of health is affected by low thyroid function. The association between serum thyroid hormones and body mass index (BMI) or obesity was examined in a cross-sectional population study (The DanThyr Study) of 4,082 eligible participants. The results suggested that thyroid function (also within the normal range) could be one of several factors acting in concert to determine body weight […]

Common Thyroid Tests To Diagnose Thyroid Diseases

Written by

Most physicians, including endocrinologists, rely on standard thyroid tests to determine their patients’ “proper” dose of thyroid replacement. The evaluation of a patient’s signs and symptoms to determine the proper dose has been reduced to the point of being unimportant to most physicians. What Is Wrong With Standard Thyroid Tests? Thyroid Stimulating Hormone (TSH) is a pituitary hormone whose function is to stimulate thyroid hormone production by the thyroid gland. It is considered the only diagnostic test for hypothyroidism and the most sensitive marker of peripheral tissue availability of thyroid hormones. The clinical reality is that relying on standard thyroid tests to determine optimal doses of thyroid replacement is inaccurate and doesn’t offer relief or proper treatment for the patient. Unfortunately, most physicians, including endocrinologists, lack the ability or confidence to clinically evaluate a patient’s thyroid status and lack understanding of the limitations of standard thyroid function tests. Reliable studies already […]
