Transcript
- 0:00Good morning, and welcome to another episode of Morning Medical with Dr.
- 0:04Chow.
- 0:06I am your host, Dr.
- 0:07Chi-Ming Chow, and today we have a comprehensive update on some of the most
- 0:12pressing medical and health news from around the world.
- 0:16As always, our goal is to keep you informed with the latest research, studies, and expert
- 0:22opinions that could impact your health and well-being.
- 0:26So without further ado, let us dive right into today's topics.
- 0:33First up, a new study has suggested a potential link between the use of popular weight loss and
- 0:39diabetes medications, specifically Ozempic and Wegovy.
- 0:44And a serious eye condition that can lead to blindness.
- 0:48The study, conducted by researchers at Harvard and published in JAMA Ophthalmology, analyzed
- 0:53data from 16,827 patients over a six-year period at the Massachusetts Eye and Ear Harvard
- 1:00Teaching Hospital.
- 1:02The active drug in both Ozempic and Wegovy is semaglutide, which belongs to a class of
- 1:07medications known as GLP-1 receptor agonists.
- 1:12Researchers focused on the incidence of non-arteritic anterior ischemic optic
- 1:17neuropathy, or NAION, a condition that affects the optic nerve and can result in sudden and
- 1:22irreversible vision loss.
- 1:24Among the 16,827 patients analyzed, 710 had type 2 diabetes with 194 being prescribed
- 1:32semaglutide medications.
- 1:35Another 975 patients were either overweight or living with obesity, with 361 of them being
- 1:41prescribed semaglutide.
- 1:43The findings were concerning.
- 1:45Among those prescribed semaglutide, a small percentage eventually developed NAION.
- 1:51Specifically, 8.9% of patients taking semaglutide for type 2 diabetes developed NAION
- 1:58compared to 1.8% who were taking non-GLP-1 medications.
- 2:03Similarly, 6.7% of those prescribed semaglutide for weight issues developed the eye condition
- 2:10versus 0.8% of those receiving other types of medications for weight reduction.
- 2:16NAION affects the optic nerve, which is responsible for carrying visual information
- 2:21from the eye to the brain.
- 2:23This condition is essentially a type of painless eye stroke where reduced or blocked
- 2:28blood flow and oxygen to the optic nerve can result in sudden vision loss.
- 2:33The study found that the risk of developing NAION was greatest within the first year of
- 2:38being prescribed semaglutide, but researchers emphasized that their findings should be
- 2:43considered tentative for now.
- 2:46Doctor Joseph Rizzo, the lead researcher and director of neuro-ophthalmology at Mass Eye and
- 2:52Ear, stressed the importance of further studies to examine these questions in a larger and more
- 2:57diverse population.
- 3:00He noted that while the use of these drugs has exploded throughout industrialized countries,
- 3:04providing significant benefits in many ways, future discussions between patients and their
- 3:09physicians should include NAION as a potential risk.
- 3:15However, it is important to highlight that medical experts are urging patients not to
- 3:19panic or discontinue their medications.
- 3:22Doctor Tom Elliott, medical director with BC Diabetes, described the association between
- 3:28semaglutide and NAION as exceedingly rare.
- 3:31He reassured patients that if they have a good reason to be taking semaglutide, the benefits
- 3:36massively outweigh the downside.
- 3:38These drugs not only help in managing diabetes and weight, but also contribute to
- 3:43cardiovascular health.
- 3:45Dr.
- 3:46Mark Eltis, president of the College of Optometrists of Ontario, added that untreated
- 3:51diabetes itself can cause severe vision problems.
- 3:55He explained that untreated diabetes can lead to leaky blood vessels at the back of the eye
- 3:59or the formation of new unstable blood vessels, which can cause hemorrhaging or bleeding.
- 4:06Novo Nordisk, the manufacturer of Ozempic and Wegovy, also weighed in, highlighting several
- 4:12limitations of the study design, which was not a randomized controlled trial.
- 4:17They pointed out that the study did not account for some potentially pertinent information such
- 4:23as the duration of diabetes in patients or whether they were smokers.
- 4:27They emphasize that the data is not sufficient to establish a causal association between GLP-1
- 4:33receptor agonist use and NAN.
- 4:36Canadian warnings for both Ozempic and Wegovy do include vision changes among potential side
- 4:42effects.
- 4:43Therefore, it is crucial for anyone considering semaglutide to speak with their health care
- 4:49provider about the risks and benefits and to be assessed for any eye conditions beforehand to
- 4:55ensure an individualized treatment plan.
- 4:58In summary, while the study's findings are significant, they should be interpreted with
- 5:03caution.
- 5:04The potential link between semaglutide and NAN highlights the importance of ongoing research
- 5:11and informed discussions between patients and health care providers.
- 5:15As always, the goal is to balance the benefits and risks. There
- 5:23There is a significant link between high sodium intake and a range of serious health issues, as
- 5:29evidenced by the fact that 90 percent of Americans consume too much salt.
- 5:34While salt undoubtedly adds flavor to your food, are you aware of the potential health
- 5:39risks of consuming it in excess?
- 5:41Dietary guidelines recommend that adults should not have more than 2,300 milligrams of sodium
- 5:47daily.
- 5:49However, the average American consumes approximately 3,400 milligrams daily, which is
- 5:55substantially higher than the recommended limit.
- 5:59Excessive amounts of salt can increase the risk of developing high blood pressure, which is a
- 6:03precursor to several other serious health conditions.
- 6:06More than 4 in 10 Americans have high blood pressure, and it can elevate the risk for heart
- 6:11disease, stroke, gastric issues, osteoporosis, kidney disease, certain types of cancer,
- 6:18obesity, and Ménière's disease.
- 6:21The World Health Organization reports that approximately 1,890,000 deaths each year are
- 6:26linked to excessive sodium intake.
- 6:29One of the primary culprits of high sodium intake is processed or convenience foods.
- 6:34These foods tend to have higher salt content because salt helps preserve them.
- 6:39However, only 15 percent of your sodium intake comes from the salt you add while cooking or
- 6:44eating.
- 6:45Some surprising sources of sodium include soups, breads, condiments, meats, and salad
- 6:51dressings.
- 6:52For instance, a single slice of cheese can have the same amount of sodium as an ounce of potato
- 6:57chips.
- 6:59To lower your salt intake, consider eating mostly fresh, minimally processed foods.
- 7:05Cutting back on high-sodium foods, like deli meats, pizza, burritos, and sandwiches can also
- 7:11help.
- 7:13Additionally, using herbs and spices instead of salt to season your food can be a healthier
- 7:19alternative.
- 7:20Reading food labels carefully is crucial as well.
- 7:23Alessandra Stenopoulos, a registered dietitian, emphasizes the importance of checking labels
- 7:29before grabbing something off the shelf.
- 7:32It is worth noting that as much as 70 percent of the sodium you consume comes from processed
- 7:37and restaurant foods.
- 7:39Therefore, preparing meals at home can significantly reduce your sodium intake.
- 7:44But what about Himalayan salt?
- 7:46Consumer testers have found that Himalayan salt contains 1,000 milligrams less sodium per
- 7:52tablespoon compared to regular table salt.
- 7:55While this is a slight improvement, it is still essential to monitor overall salt consumption
- 8:00to maintain good health.
- 8:03In summary, while salt is an essential component of our diet, excessive consumption
- 8:09poses significant health risks.
- 8:11By being mindful of the sources of sodium in your diet and making conscious choices to
- 8:16reduce your intake, you can significantly lower your risk of developing serious health
- 8:21conditions.
- 8:22As always, consult with your health care provider for personalized advice and
- 8:27recommendations.
- 8:29Weight stigma is a pervasive issue in health care, and it is time for physicians to address
- 8:35it head-on.
- 8:36Doctor Emingi Jha, a physician and nonfiction writer, recently discussed the harmful effects
- 8:42of weight stigma in an article published on MedPage Today.
- 8:46Doctor Jha highlights that weight stigma is not just a societal issue, but a medical one that
- 8:51can have severe consequences for patients.
- 8:54Being shamed by physicians is unfortunately not uncommon.
- 8:58A 2009 survey revealed that 50 percent of patients recalled at least one interaction with
- 9:03a physician where they left feeling ashamed, with weight being the most common topic.
- 9:09Alarmingly, a 2022 poll by Doctor Jha found that 70 percent of respondents had been shamed
- 9:16by their health care teams.
- 9:18This is not just an issue of hurt feelings.
- 9:20It has real implications for patient care.
- 9:24Studies have shown that physicians often show less respect and make less effort to build
- 9:29rapport with patients who live in larger bodies.
- 9:33This lack of effort extends beyond emotional connections.
- 9:37For example, mothers with obesity are less likely to receive support for breastfeeding
- 9:41from health care professionals, which can negatively impact infant health.
- 9:47Even when it comes to weight loss, those who experience weight stigma from their physicians
- 9:51are less likely to succeed in losing weight compared to those who do not feel judged.
- 9:57Perhaps the most damaging outcome of patient shaming is the loss of a therapeutic
- 10:02relationship.
- 10:05In the 2009 study, 45% of patients who felt shamed by a physician either left, avoided, or
- 10:12lied to their physician.
- 10:14This avoidance can prevent patients from seeking essential care, such as cancer
- 10:19screenings and prenatal care.
- 10:20Consequently, patients living with obesity have higher cancer rates and worse obstetric
- 10:25outcomes, raising the question of whether obesity is the risk factor or if weight stigma
- 10:30itself plays a significant role.
- 10:33It is crucial to note that addressing excess weight is important and does not inherently
- 10:38constitute weight stigma.
- 10:40However, when weight becomes the sole focus for all health-related issues, it acts as a
- 10:45gatekeeper, restricting access to comprehensive care.
- 10:49Doctor Chow has worked extensively with women suffering from hidradenitis suppurativa, a
- 10:55chronic skin condition often comorbid with obesity.
- 10:59Many patients reported that their doctors advised them to lose weight without even
- 11:04examining their skin.
- 11:06This failure to look beyond weight can lead to missed diagnoses and delayed care.
- 11:12Moreover, the stigma surrounding weight is often baseless.
- 11:16In the case of hidradenitis suppurativa, there is no strong evidence that weight loss
- 11:21consistently leads to clinical improvement.
- 11:24On the contrary, rapid weight loss after bariatric surgery may worsen symptoms in up to
- 11:2969% of patients.
- 11:32This highlights how physicians can become blind to their biases, failing to provide adequate
- 11:37care to patients living with obesity, who already suffer higher all-cause mortality.
- 11:44So what can be done to break this cycle of weight stigma in medicine?
- 11:49First, the medical community must include people of all sizes in clinical trials.
- 11:55Currently, patients living with obesity are not required to be included in United States
- 12:01clinical trials, making drug dosing in larger bodies a gray area.
- 12:06This can be life-threatening in cases such as infections, blood clots, and cancer.
- 12:11Additionally, health care environments should adapt their facilities, equipment, and policies
- 12:18to accommodate larger bodies appropriately.
- 12:22Second, health care should be addressed at every size in a nonjudgmental manner.
- 12:28The Health at Every Size framework teaches that health care is a human right for people of all
- 12:34sizes and that refusing to provide care until arbitrary weight loss criteria are met could
- 12:40violate a patient's bodily autonomy.
- 12:43When discussing weight, health care providers should use person-centered, collaborative, and
- 12:49respectful language.
- 12:51It is essential to obtain permission before weighing patients and to ensure that the focus
- 12:57remains on their overall health, not just their weight.
- 13:01Lastly, training to combat anti-fat biases must begin early in medical education.
- 13:07A 2010 randomized control trial found that medical students were more likely to recommend
- 13:13lifestyle changes and less likely to prescribe symptom-relieving medications for patients
- 13:18living with obesity.
- 13:19By the time they reach residency, an alarming level of anti-fat bias exists across all
- 13:26specialties.
- 13:27This indicates that either medical education cultivates weight stigma or does a terrible job
- 13:32correcting it, or perhaps both.
- 13:36Dr.
- 13:36Ajay emphasizes the importance of breaking this cycle.
- 13:41When meeting new patients living with hidradenitis suppurativa, she makes it a point
- 13:45to tell them your weight did not cause your HS.
- 13:49Many patients are moved to tears when they hear this, as weight stigma has created significant
- 13:55trauma outside the exam room.
- 13:58It is crucial for health care providers to break this cycle in the one place where people
- 14:03expect care and compassion.
- 14:06Everybody should have a place in medicine, and everybody deserves to heal too.
- 14:11As we wrap up today's episode, let's explore some practical tips for greening your outdoor
- 14:16space, which could potentially boost your mood.
- 14:20City living can often be a mood killer, with pollution, loud sirens, and congestion taking
- 14:26their toll.
- 14:27However, a recent study has revealed that living near diverse birds and trees can
- 14:33significantly lift your spirits.
- 14:36Even if you reside in a condo or an apartment with a small balcony, there are ways to
- 14:40transform your green space and bring nature to your doorstep.
- 14:45Ryan Godfrey, a botanist with the World Wildlife Fund Canada living in Toronto,
- 14:51emphasizes the positive health benefits of having nature close.
- 14:55He shares his personal experience of living in a condo and using his balcony to grow a native
- 15:00plant garden in containers.
- 15:02According to Godfrey, this approach attracts birds, insects, and various forms of
- 15:07biodiversity, enriching his urban living experience.
- 15:12A Canadian study published in Nature last month found that living in a city neighborhood rich
- 15:17with bird diversity and tree species was linked to increased reporting of good mental health.
- 15:24The study found that people living in areas with a greater variety of birds reported
- 15:30feeling happier by 6.64%.
- 15:33Similarly, those living near a wider range of tree species reported 5.36 percent higher rates
- 15:39of good mental health.
- 15:42Even with limited outdoor space, from a compact balcony to a modest backyard, these tips will
- 15:49help you attract birds to your haven.
- 15:51First, consider growing native plants.
- 15:55Native plants are species specific to your region and have developed a special, complex,
- 16:01and deep relationship with insects and birds in their ecosystem.
- 16:05Their local adaptation makes them naturally tough and low maintenance, making them an
- 16:11excellent choice for urban gardening.
- 16:15Examples of regionally specific native plants include Saskatoon berries, a sweet and tart
- 16:20fruit prevalent in the prairies, satin flower found on the West Coast, and the ever-popular
- 16:26wild strawberry in Ontario.
- 16:28Growing a native plant garden and embracing the wildness is a way to de-stress.
- 16:33You insert yourself into the ecosystem, bring nature close, and get to learn about native
- 16:38plants, how they grow, and what kinds of pollinators they attract.
- 16:43If you are short on space, container gardens can be a great solution for your balcony or
- 16:47patio.
- 16:48You can use buckets, barrels, bushel baskets, and plastic bins for this purpose.
- 16:54Proper drainage is essential for happy plants, so ensure your containers have drainage holes.
- 16:59If needed, you can easily poke or drill some holes yourself.
- 17:03This prevents water from accumulating and potentially rotting the roots of your plants.
- 17:09Container plants also dry out faster than those in the ground, due to increased sun exposure
- 17:13and wind.
- 17:15Be prepared to water frequently.
- 17:17Most plants will need it daily during hot weather.
- 17:20Some great options for container gardening include salad greens, garlic, tomatoes, corn,
- 17:25beans, carrots, and herbs like thyme, oregano, and mint.
- 17:29Vertical gardens are another excellent solution for those with limited space.
- 17:34Use wall-mounted planters, hanging pots, or trellises to create a vibrant green display.
- 17:41Great plant choices for vertical gardens include herbs like thyme and oregano,
- 17:47vegetables like beans and peas, and decorative plants such as ivy and ferns.
- 17:53Ryan Godfrey mentioned that he is growing peas on his balcony where they are climbing up some
- 17:58of his native grasses and an edible native species called sunchokes.
- 18:02Long and narrow window boxes can also be used for a herb garden filled with basil, oregano,
- 18:08and parsley.
- 18:09Simply snip off leaves from the outside of the plant, and they will continue to grow week
- 18:13after week.
- 18:15Creating a bird-friendly environment in your green space adds life and movement while also
- 18:20helping with pollination and pest control.
- 18:23Native grasses with long seed heads are a favorite among birds.
- 18:27Leaving these seed heads intact provides a natural food source that birds will appreciate.
- 18:32Birds may also come to eat insects from the plants, creating a space that resembles their
- 18:37natural habitat and making it more inviting for them to come and feed.
- 18:42While bird feeders and houses can be another way to attract birds, it is important to
- 18:47remember that regular cleaning is crucial.
- 18:50Unclean feeders and houses can become breeding grounds for disease and parasites, potentially
- 18:55harming the local bird population.
- 18:57Some insects, like ladybugs, are beneficial for your garden as they are natural predators of
- 19:04aphids.
- 19:06Bees and butterflies play a vital role in pollination, ensuring the reproduction of many
- 19:11flowering plants.
- 19:13Exploring perennials can also be a great option for your garden.
- 19:17Perennials are a long-term investment in your garden's beauty.
- 19:21Unlike annuals that need replanting each year, perennials return season after season, bursting
- 19:27with vibrant blooms and lush foliage.
- 19:30Their ability to live for multiple years reduces the need for frequent replanting,
- 19:34making them especially beneficial in urban settings, where garden space may be limited or
- 19:39harder to access.
- 19:41The majority of native plants are perennials, promising more suitability for urban gardening.
- 19:49Wild strawberries are a great example.
- 19:52If you have no idea where to start, plant some wild strawberries.
- 19:57They are very fun to grow and send runners around to plant themselves into other
- 20:03containers.
- 20:04As we conclude today's episode, remember that creating a small nature-friendly space can
- 20:10boost your mood and contribute to a healthier urban environment.
- 20:14Whether you have a compact balcony or a modest backyard, these tips will help you bring nature
- 20:19closer to your doorstep.
- 20:21Thank you for joining us on Morning Medical with Dr.
- 20:24Chow.
- 20:25Stay healthy and see you next time.
