Dr. Gary Pepper and Dr. Paul Aoun discuss recent findings about thyroid hormone treatment at the 15th International Thyroid Congress
According to experts, 10 to 20% of hypothyroid individuals fail to respond completely to T4-only (levothyroxine, Synthroid) treatment. Dr. Anthony Bianco, the president of the American Thyroid Association, and his associates believe this is due to genetic variations in the way thyroid hormone is converted in the body from T4 into T3. T3 is the much more potent form of thyroid hormone and unless the cells of the body receive enough T3, normal function cannot be achieved and symptoms of low thyroid such as fatigue, mental fogginess, constipation, muscle aches etc, persist. Based on the research conducted by Dr. Bianco and colleagues it is thought that in those with the genetic trait making T4 treatment ineffective, blood tests would show low T3 levels. (more…)
By Gary Pepper, M.D. Last week I posted a few highlights from the just concluded International Thyroid Congress. One of the research papers presented at the meeting generated particular concern. Endocrinologists and scientists at UCLA Medical Center led by Dr. Jerome Hershman investigated the potential for pesticides to damage the DNA of thyroid cells. The group focused on double strand breaks, the type of damage that could eventually lead to cancer. This is a particularly relevant point due to the explosion in newly diagnosed thyroid cancers being reported in many areas of the world. The increase is likely related, at least in part, to improved diagnostic techniques for thyroid cancer but could also represent environmental influences. (more…)
Update from the 15th International Thyroid Congress, Orlando Florida, October, 2015 By Gary Pepper, M.D. Â Â Â Â I just returned from Orlando, Florida, where I attended the 15th International Thyroid Congress and want to provide a report of my experience, to readers of metabolism.com. This was truly an international event with an estimated 50% of the attendees from outside the U.S. Organizers of this event describe it as, â€œRenowned experts in thyroid function and biology, diagnosis and management of thyroid disease, and novel therapies for treating thyroid cancer are gathering at the 15th International Thyroid Congress (ITC) to present, discuss, and debate the latest advances in thyroidology. Held every five years, the ITC is a collaborative meeting of the four world thyroid associations; the ATA (American Thyroid Association), Asia-Oceania Thyroid Association (AOTA), European Thyroid Association (ETA), and Latin American Thyroid Society (LATS).â€ I was particularly excited to be attending this conference this year since my colleagues, Drs. Paul Cassanova and Kathryn Reynolds and I were presenting our study on the use of combination T3 plus T4 for the treatment of underactive thyroid (hypothyroidism). Here are some papers I found to be of particular interest; (more…)
Why Patients Arenâ€™t Receiving the Most Effective Treatment for Hypothyroidism By Gary Pepper, M.D.
For the past 3 to 4 decades endocrinologists worldwide have adhered to the belief that only synthetic T4 (the most abundant of 4 thyroid hormones produced by the thyroid) is appropriate therapy for a sluggish thyroid even though it is known that a substantial number of those treated with T4 only continue to suffer from persistent symptoms of the disease. This may be because under normal conditions the thyroid produces two principle hormones T4 and T3. In 2013 an NIH study showed that 50% of those with hypothyroidism preferred treatment which includes T3 and our group reported that 78% of a subgroup of patients preferred T3 containing medication to treat hypothyroidism . (more…)
The 2013 guidelines issued by the American Association of Clinical Endocrinologists and the American Thyroid Association reiterated their long standing opinion that only a single hormone, T4 (Synthroid, levothyroxine) is advised for treatment of hypothyroidism. These key organizations
The mission of the The Thyroid Project is to encourage sharing of information and experience between the public and the medical community about the treatment of hypothyroidism (low thyroid function). For at least the past few decades there is a growing awareness of â€œsomething missingâ€ in the way suffers of hypothyroidism are treated for their disease.
Too many patients, as documented in an on-line study of 12,000 individuals conducted by the American Thyroid Association published in June 2018, (https://doi.org/10.1089/thy.2017.0681) , complain of persistent symptoms of hypothyroidism despite what their doctors believe is successful treatment with levothyroxine (brands include Synthroid, Unithroid, Tirosent, Levoxl). We believe something needs to be done to resolve this conflict between patients and their doctors.
Diabetes can be defined simply as elevated blood sugar levels. What exactly is high blood sugar and when should someone be concerned about their level? Does having prediabetes mean diabetes is around the corner? Metabolism.com tackles this tricky but important topic in this comprehensive review.
By Gary M. Pepper, M.D. Ozempic, Rybelsus, Trulicity, Wegovy, Saxenda are the central players in the weight loss craze sweeping across the globe. Metabolisim.com has been monitoring this phenomenon from its beginnings in 2008 with its report “Lizard Spit Reduces Blood Sugar and Appetite”, regarding the first drug in this class, Byetta (exenatide). Caught In the middle of the current chaos are the medical experts who treat diabetes and have been prescribing these medications for more than a decade. Here is a brief commentary from one such board certified endocrinologist; “I started treating Type 2 diabetics with GLP-1 agonists more than 10 years ago. In some respects, these medications have revolutionized the treatment of diabetes by lowering blood sugar effectively and promoting weight loss at the same time, a unique combination of benefits. Not everyone benefits from these drugs to the same degree unfortunately, and I have seen lots of patients experience unacceptable side effects from them. Nothing though, has prepared me for what is happening now. Too often, I find myself confronting someone who expects me to prescribe one of these drugs just so they can lose weight. Sadly, one extreme example was someone who, despite battling a life threatening medical condition, was insistent on getting a prescription. At the same time my diabetic patients are scrambling to find a place to buy their medications if they can even afford it. It is disheartening, to say the least, and I dread the negative interactions with some of my patients I now face almost daily.”
Off- Label Use
The FDA is the U.S. government’s department tasked with evaluating and approving drugs for specific medical conditions. When a new medication is approved for treating a medical condition by the FDA the agency will, at the same time, set strict guidelines for exactly which patients may use the newly approved drug. When a medication is used “off-label” it means that these limitations are being overridden by the provider for a potential benefit which outweighs the drugs risks. It is a general misconception that off-label means illegal; it does not. This practice has been going on for ages and more than 20% of prescriptions in the United States are prescribed off-label. A common example is the use of beta-blockers (approved for heart problems) for the treatment of performance anxiety.
GLP-1 agonist drugs, as discussed recently by metabolism.com. were originally approved for the treatment of Type 2 diabetes in adults. In the past few years most of these same medications have gained unprecedented popularity for their “off-label” weight loss benefit. Of the 5 GLP-1 agents presently in U.S. pharmacies only Wegovy (semaglutide) and Saxenda (liraglutide) are FDA approved for treating obesity. Of these two, Wegovy is the newer and had been much more popular that its sister drug Saxenda, probably due to being dosed only once weekly compared to daily for Saxenda and less likely to cause side effects. Due to Wegovy’s soaring popularity, its manufacturer, Novo Nordisk, increased the price of Wegovy two times since its initial release.
by Gary M. Pepper, M.D. and Sam Jeans, MSc The global anti-obesity drug market, in 2021was valued at over $2 billion. Within one year this figure had skyrocketed to $8 billion and is expected to climb to nearly $ 20 billion by 2027. This astounding growth is a reflection of soaring obesity rates, and the arrival of a new class of weight loss medication fueling a craze both in the USA and across the world.
The FDA and global health regulators, until very recently, had maintained a very tight ship when it comes to treating obesity with medication, placing the emphasis on diet and exercise rather than weight loss drugs. Since the 80s, anti-obesity drugs continued to be controversial, and a more stringent FDA implemented ongoing safety trials along with other precautions. There is some speculation that a shift in attitude toward approval of weight loss medication by the FDA , is underway
Weight loss drug controversies are far from over and, in fact, may soon rival the amphetamine crisis of the 70’s. For that reason, metabolism.com has felt it important to provide our guide to weight loss drug issues, past and present.
Anti-Obesity Drugs Timeline
Prescription drugs for lifestyle diseases such as obesity were marketed heavily throughout the 1950s to the 1970s. Amphetamines entered the public domain after the Second World War where they were used extensively in the military.
In the 50s, walk-in clinics prescribed diet pills with other medications almost at random, with or without genuine concern for one’s weight. These brightly colored pills became known as “rainbow pills”.
In the 1960s and 1970s, the so-called “rainbow pill diet” of pills was finally coming to an end as the FDA began to systematically ban many of the drugs involved. A high-profile expose by investigative journalist Susanna Mcbee, published in Life magazine, brought attention to this new modern public health crisis.
The rainbow pill diet combined amphetamines, laxatives, thyroid hormones, and even diuretics to produce extreme weight loss, combined with benzodiazepines, barbiturates, and steroids to reduce side effects, and antidepressants to suppress medication-induced insomnia and anxiety.
In 1968, rainbow pills were linked to over 60 deaths, with numerous accounts of their devastating impact surfacing in the news and media. Within just two months, 48 million pills were seized and destroyed. Nevertheless, amphetamine-based diet pills remained extremely popular throughout the 1970s. In 1978, some 3.3 million prescriptions for amphetamines were written each year, with some 50 million pills a year ending up in the black market.
In 1979, the FDA banned amphetamines as a weight loss aid, but that is hardly the end of the USA’s love affair with obesity medication.
Here’s a brief timeline of recent anti-obesity drugs:
