Wegovy Side Effects, Acne Treatments, and Health Misinformation Insights · Morning Medical with Dr. Chow

• 0:00
  Welcome to another episode of Morning Medical with Doctor Chow, where we dive into the latest
• 0:05
  medical and health news from around the globe.
• 0:08
  I'm your host, Chi-Ming Chow, and today we're exploring some intriguing developments in the
• 0:13
  world of medicine.
• 0:14
  Let's kick off with a fascinating topic that's been making waves in the medical community:
• 0:20
  hair loss as a potential side effect of the weight loss drug Wegovy, also known as
• 0:25
  semaglutide.
• 0:29
  Recent reports have surfaced suggesting that women who use semaglutide may face a
• 0:35
  significantly higher risk of hair loss compared to those using another weight-loss medication,
• 0:40
  bupropion-naltrexone, marketed as Contrave.
• 0:44
  A preprint study, employing a random sample of 16 million patients, discovered that women
• 0:50
  initiating semaglutide had more than a twofold increased risk of hair loss.
• 0:56
  The incidence rate for these women was more than double that of those on
• 1:00
  bupropion-naltrexone, at 26.5 versus 11.8 per 1,000 person-years, respectively.
• 1:07
  This research, led by Mahyar Etminan and his colleagues at the University of British
• 1:12
  Columbia, highlights a new phenomenon that doctors should be aware of.
• 1:17
  While semaglutide offers benefits like heart attack reduction for people with diabetes, the
• 1:23
  risk-benefit tradeoff might differ for those who are otherwise healthy and seeking weight
• 1:28
  loss.
• 1:29
  The findings suggest that hair loss could be a potential limitation for women considering
• 1:35
  semaglutide for weight loss purposes.
• 1:38
  The study also references clinical trials for semaglutide and another weight-loss drug,
• 1:45
  tirzepatide, where an imbalance in hair loss was noted among female participants.
• 1:51
  Interestingly, hair loss was more pronounced in those who achieved greater weight loss.
• 1:57
  This suggests a possible link between rapid weight loss, nutrient deficiencies, and
• 2:02
  hormonal changes as contributing factors.
• 2:06
  Despite these findings, there are still many unanswered questions, such as the severity and
• 2:12
  duration of hair loss, and whether it is reversible.
• 2:16
  The United States Food and Drug Administration has been reviewing reports of hair loss among
• 2:22
  users of GLP-1 receptor agonists, a class of drugs that includes semaglutide.
• 2:29
  However, they have not yet provided a definitive update on this particular side
• 2:34
  effect.
• 2:36
  Etminan and his team propose that the physiological stress from rapid weight loss
• 2:40
  could lead to a condition known as telogen effluvium, where hair enters the shedding phase
• 2:45
  prematurely.
• 2:46
  Additionally, the appetite-suppressing effects of GLP-1 agents could lead to nutrient
• 2:52
  deficiencies, particularly in protein, which is essential for hair health.
• 2:57
  Other side effects, such as nausea and vomiting, could further exacerbate the risk of
• 3:03
  hair loss due to the loss of vital nutrients and vitamins.
• 3:08
  While the data is still limited, this emerging link between GLP-1 agents and hair loss
• 3:13
  warrants further study.
• 3:15
  We need more research to fully understand the implications and help guide patients and
• 3:19
  healthcare providers in making informed decisions about weight-loss medications.
• 3:25
  Today, we're delving into an issue affecting one of the key regulatory bodies in the United
• 3:29
  States.
• 3:31
  Thousands of employees at the Food and Drug Administration returned to their headquarters
• 3:34
  recently, only to be met with a slew of challenges as they adjusted to the
• 3:39
  return-to-office mandate.
• 3:40
  This mandate was part of a broader initiative from the Trump administration aiming to
• 3:45
  significantly reduce the federal workforce.
• 3:48
  On the first day back, employees encountered overflowing parking lots and long security
• 3:53
  lines, creating a chaotic start to their workday.
• 3:58
  The Food and Drug Administration's main campus in White Oak, Maryland, was particularly hit
• 4:03
  hard.
• 4:05
  This site, originally a naval weapons testing facility, was not designed to accommodate the
• 4:10
  full workforce of the agency, which includes around 20,000 scientists, attorneys,
• 4:16
  inspectors, and support staff.
• 4:20
  Staff members reported spending hours searching for available office space and basic supplies
• 4:24
  like chairs and desks.
• 4:26
  Some employees even resorted to borrowing supplies from conference rooms and other
• 4:30
  buildings due to the shortage.
• 4:32
  Photos from the scene showed makeshift office setups with folding chairs and tables in
• 4:38
  hallways and lobbies.
• 4:40
  This lack of organization led to significant disruption and lost work hours.
• 4:46
  Beyond the logistical issues, there was also a concern regarding the safety of the drinking
• 4:51
  water at the facility.
• 4:53
  The presence of Legionella bacteria, which causes Legionnaires’ disease, was detected in
• 4:59
  several buildings.
• 5:00
  Although employees received an email assuring them the water was safe, the lack of detailed
• 5:05
  information about testing and corrective measures left many uneasy.
• 5:09
  As a result, most staff brought their own water to work.
• 5:14
  This situation highlights the difficulties that can arise when transitioning back to in-person
• 5:19
  work environments, especially in large organizations like the Food and Drug
• 5:23
  Administration.
• 5:24
  The agency is trying to ensure its staff can continue their critical public health work
• 5:29
  despite these challenges.
• 5:31
  However, the issues faced by the employees underscore the need for careful planning and
• 5:36
  communication when implementing such significant changes.
• 5:42
  Let's turn our attention to a medication that's been gaining traction in dermatology circles:
• 5:47
  spironolactone.
• 5:49
  Traditionally used for cardiovascular conditions, spironolactone is now being
• 5:54
  prescribed increasingly to address acne and other androgen-related issues, especially among
• 5:59
  young women and girls.
• 6:01
  However, this rise in usage comes with unresolved safety questions.
• 6:06
  According to a study published in JAMA Network Open, the use of spironolactone among young
• 6:12
  women and girls has seen a significant increase since the year 2000.
• 6:17
  The study highlights that new prescriptions for spironolactone in this demographic have risen
• 6:23
  from 17 per 100,000 covered individuals in 2000 to 88 per 100,000 in 2020.
• 6:32
  This data was drawn from a database of United States insurance claims, which included 38
• 6:38
  million generally healthy young women and girls.
• 6:41
  Of these, about 1.2 percent had initiated the use of spironolactone.
• 6:48
  Interestingly, the largest increase in spironolactone initiation was observed among
• 6:53
  women aged 19 to 25.
• 6:55
  The majority of these new users were diagnosed with acne, representing 55.5 percent of the
• 7:01
  cases, followed by hirsutism and polycystic ovary syndrome, both of which are also
• 7:07
  androgen-related conditions.
• 7:09
  It's important to note that these uses are considered off-label, as spironolactone is
• 7:14
  approved by the United States Food and Drug Administration for conditions like heart
• 7:18
  failure, hypertension, edema, and primary hyperaldosteronism.
• 7:24
  The growing use of spironolactone for acne is backed by studies supporting its efficacy as a
• 7:29
  hormonal treatment.
• 7:31
  However, the application remains off-label, and the safety profile of spironolactone in
• 7:37
  relatively healthy young individuals is still not well understood.
• 7:41
  The drug's established safety risks include hyperkalemia, hypotension, worsening renal
• 7:48
  function, electrolyte and metabolic abnormalities, and gynecomastia.
• 7:54
  These risks are primarily drawn from trials involving older patients with heart failure,
• 8:00
  rather than the younger population now using it for acne.
• 8:04
  Despite the American Academy of Dermatology's stance that potassium monitoring is not
• 8:08
  necessary for healthy young women using spironolactone for acne, many prescribers
• 8:14
  continue to monitor potassium levels.
• 8:16
  This is due to the potential risks associated with hyperkalemia, a condition characterized by
• 8:22
  elevated potassium levels in the blood, which can be dangerous if not managed properly.
• 8:28
  The study conducted by Sarah Soppe and her team at the University of North Carolina at Chapel
• 8:32
  Hill underscores the need for further safety studies.
• 8:36
  They utilized the Merative MarketScan Commercial Claims and Encounters Database to
• 8:40
  identify new prescriptions and noted that 11.5 percent of spironolactone initiators were
• 8:47
  between the ages of 12 and 18.
• 8:50
  These individuals typically did not have hypertension or congestive heart failure,
• 8:55
  conditions for which spironolactone is traditionally prescribed.
• 8:59
  The findings from this study suggest that the use of spironolactone among young women and
• 9:03
  girls is not only notable but growing.
• 9:07
  The majority of these users require higher doses than those examined in clinical trials
• 9:12
  for cardiovascular disease, highlighting the urgent need for more research into its safety
• 9:17
  and efficacy in this population.
• 9:21
  Today, we're diving into an important question that's been on the minds of many as measles
• 9:26
  cases continue to rise: Do adults need a measles booster?
• 9:31
  The good news is that most Americans are well-protected.
• 9:35
  Those who received two doses of the measles, mumps, and rubella vaccine, known as the MMR
• 9:40
  vaccine, have a 97 percent effectiveness rate against measles.
• 9:45
  Even for individuals who received just one dose of the MMR vaccine, typically those vaccinated
• 9:51
  between 1968 and 1989, the protection rate is still an impressive 93 percent.
• 9:57
  Experts also point out that people born before 1957 are generally considered to have natural
• 10:03
  immunity due to widespread exposure to measles during their early years.
• 10:07
  Doctor David DiJohn, a pediatric infectious diseases specialist at the University of Nevada
• 10:13
  Las Vegas, emphasizes that there are currently no recommendations for adults to get another
• 10:18
  measles shot.
• 10:20
  However, there are certain groups who might benefit from a booster.
• 10:25
  One such group includes people born after 1957 who were vaccinated before 1968.
• 10:32
  During that period, a single-dose inactivated measles vaccine was used, which was later found
• 10:38
  to be less effective and long-lasting compared to the current live-attenuated vaccine.
• 10:44
  Doctor Andrew Handel, a pediatric infectious disease physician at Stony Brook Medicine in
• 10:50
  New York, recommends that anyone who received the inactivated vaccine between 1963 and 1967
• 10:58
  should consider getting a dose of the current MMR vaccine.
• 11:03
  Another group that may want to consider a booster includes those who have regular contact
• 11:07
  with individuals who cannot receive the MMR vaccine, such as unvaccinated pregnant women
• 11:13
  and immunocompromised individuals.
• 11:16
  These vulnerable groups rely on others being vaccinated to help protect them from the virus.
• 11:22
  Additionally, healthcare workers should ensure they have two documented doses of the MMR
• 11:27
  vaccine, as recommended by a recent advisory from the Centers for Disease Control and
• 11:31
  Prevention.
• 11:33
  For adults who are not at high risk of exposure, the Centers for Disease Control and
• 11:39
  Prevention advises that they should at least have one documented dose of the MMR vaccine or
• 11:46
  other evidence of immunity, like a positive measles immunoglobulin G test.
• 11:52
  Doctor James Cutrell, an infectious disease specialist at UT Southwestern Medical Center,
• 11:58
  suggests that if a patient is unsure about their vaccination status, they could consider
• 12:02
  checking a measles titer to determine if they need a measles vaccine.
• 12:06
  For those without any medical contraindications, getting a booster shot could
• 12:10
  be a precautionary measure, according to Doctor Handel.
• 12:14
  Doctor DiJohn adds that there's no significant downside to getting an MMR vaccine in a healthy
• 12:21
  person.
• 12:22
  Although measles was declared eliminated from the United States in 2000, meaning it lacked
• 12:28
  continuous spread for over a year, recent years have seen a resurgence in cases.
• 12:33
  This resurgence underscores the importance of maintaining vigilance and ensuring adequate
• 12:38
  vaccination coverage to prevent further outbreaks.
• 12:43
  In today's world, we're constantly bombarded with information, and unfortunately, not all of
• 12:48
  it is accurate.
• 12:50
  Health misinformation is particularly pervasive, and it's critical to arm ourselves
• 12:54
  with the tools necessary to discern fact from fiction.
• 12:59
  Recently, infectious disease researcher Laurel Bristow shared her insights on how to spot
• 13:04
  misinformation in a conversation with Doctor Sanjay Gupta on his podcast, Chasing Life.
• 13:11
  Laurel Bristow, who gained recognition during the pandemic for debunking myths and conspiracy
• 13:16
  theories, emphasizes the importance of skepticism.
• 13:20
  First and foremost, if something seems too extreme—either too good or too bad to be
• 13:25
  true—it probably is.
• 13:28
  Bristow advises that we should approach such claims with caution and think critically about
• 13:33
  the information we're consuming.
• 13:35
  Another tip she offers is to avoid black-and-white thinking.
• 13:40
  Science rarely deals in absolutes, so if someone is presenting a health claim as a
• 13:44
  cure-all or an absolute danger, it's wise to question it.
• 13:49
  Are the limits of what's known about the situation clearly stated?
• 13:52
  Is the level of risk being properly contextualized?
• 13:55
  These questions can help us navigate the gray areas of scientific claims.
• 14:00
  Bristow also warns against emotional manipulation.
• 14:03
  Untrue medical claims often use fear to grab attention, emphasizing danger to you and your
• 14:09
  family.
• 14:09
  Instead of giving in to panic, she suggests delving deeper into the claims.
• 14:14
  Look for large, well-designed studies that back up the information, rather than relying on
• 14:19
  anecdotal evidence.
• 14:22
  It's also important to be wary of sales pitches.
• 14:25
  If someone is alerting you to a new health issue and simultaneously offering a solution,
• 14:30
  that's a red flag.
• 14:33
  Investigate the source of the information and check for any potential conflicts of interest.
• 14:39
  If the person or organization presenting the information stands to benefit financially, it's
• 14:44
  crucial to scrutinize their claims even more closely.
• 14:48
  Finally, Bristow encourages finding and following trusted science communicators.
• 14:53
  These individuals can help explain the limitations of current knowledge and provide
• 14:57
  context for new findings.
• 14:59
  By understanding the boundaries of what we know, it's easier to spot bad science and
• 15:03
  prevent the spread of misinformation.
• 15:06
  As we wrap up today's episode, remember that staying informed and critical of the
• 15:11
  information we consume is essential.
• 15:14
  By applying these tips from Laurel Bristow, we can better protect ourselves against health
• 15:18
  misinformation.
