    Unusual bleeding during and after pregnancy

    When should pregnant women be concerned? Awareness of the dangers associated with abnormal bleeding during pregnancy and after childbirth can be lifesaving for both women and their babies.

    Dr. Mzuvele Archwell Hlabisa, an obstetrician and gynaecologist at Netcare Kingsway Hospital, emphasizes that while many people are unaware that over a third of pregnant women may experience bleeding for various reasons, it is crucial to determine the exact cause.

    "Although some bleeding is normal in the postpartum period, excessive bleeding can be life-threatening. It is often difficult for women to discern if their bleeding is normal or not, but a good rule of thumb is to have any bleeding during pregnancy checked by a healthcare professional," says Dr. Hlabisa.

    He notes that around 35% of women experience bleeding in the first trimester. "As the pregnancy progresses, the likelihood of bleeding decreases, so it’s reassuring when women reach the mid-trimester, from 13 to 28 weeks of gestation."

    Bleeding could indicate a miscarriage or a threatened miscarriage, and severe pain with bleeding could be related to placental abruption, a serious condition where the placenta prematurely separates from the womb. These conditions require immediate medical assessment.

    Spotting In early pregnancy, some women may experience spotting, known as implantation bleeding, when the embryo implants in the uterine wall. ...Read full article

    A New Global Approach to Diagnosing and Treating Obesity
    A global group of experts has proposed an innovative framework for diagnosing and managing obesity, moving beyond the traditional reliance on body mass index (BMI), which has known limitations. The new approach focuses on distinguishing early indicators of obesity (pre-clinical) from more advanced stages (clinical) to enhance understanding and treatment.

    This refined method incorporates additional measures of excess body fat along with BMI, as well as objective signs and symptoms linked to individual health concerns. Published in The Lancet Diabetes & Endocrinology and endorsed by over 75 medical organizations worldwide, the framework aims to improve obesity diagnosis, reduce stigma, optimize healthcare resources, and promote equitable access to effective treatments.

    By addressing shortcomings in traditional methods, this approach seeks to better support the over one billion people living with obesity globally.

    Ozempic Linked to Increased Risk of Rare Eye Condition
    Globally, many individuals seeking weight loss have turned to Ozempic, a medication originally prescribed for diabetes management that has gained attention as a so-called "miracle drug." However, two significant investigations conducted at the University of Southern Denmark have raised concerns about its potential side effects, including a rare but serious condition affecting the optic nerve, which can lead to permanent blindness.

    The condition, known as non-arteritic anterior ischemic optic neuropathy (Naion), occurs due to a sudden loss of blood supply to the optic nerve. Researchers found that Ozempic more than doubles the risk of developing Naion, which is irreversible.

    In the first investigation, researchers monitored 424,152 diabetic patients over five years and observed an increase in Naion cases from 9 to 23 per 100,000 among those using Ozempic. These findings were published in the International Journal of Retina and Vitreous. A second study involving 62,000 patients from Denmark and Norway reported a rise in Naion cases to 21 per 100,000 among Ozempic users.

    The researchers emphasized that diabetic patients should not stop their prescribed use of Ozempic but advised that its potential link to Naion be closely monitored. Untreated diabetes can also lead to eye complications, though these are generally less severe than Naion.

    Ozempic has been available in South Africa since 2017, with approval from the South African Health Products Regulatory Authority (SAHPRA) for diabetes management. While its primary purpose is diabetes control, it is also frequently prescribed for weight loss, both locally and internationally. The drug works by mimicking a natural hormone that signals fullness to the brain and slows digestion. Although developed for long-term use, weight loss remains one of its notable side effects for diabetic patients.

    Eye Health May Reveal Stroke Risk Through Vascular Changes, Study Finds
    Changes in the eyes can signal a variety of health issues, including conditions like diabetes and high blood pressure. A recent study has discovered a set of 29 vascular health indicators found on the retina that could serve as a unique "fingerprint" to help predict a person’s risk of having a stroke. This method offers a less invasive alternative to traditional stroke risk tests.

    Doctors have long recognized that the eyes provide valuable insights into a person's overall health, with the retina being one of the few areas where blood vessels can be examined directly without the need for invasive procedures. According to Mingguang He, MD, PhD, Chair Professor of Experimental Ophthalmology at The Hong Kong Polytechnic University, and lead author of the study, changes in retinal blood vessels can indicate underlying systemic vascular conditions such as hypertension, diabetes, and atherosclerosis. Now, this new research suggests these changes could also help identify stroke risk.

    GLP-1 Medications Impact Convenience Store Sales, Especially for High-Profit Items
    GLP-1 medications, which are helping millions of people lose weight by curbing their appetites, might not yet be a top concern for convenience store retailers. However, recent findings suggest this could change in the near future.

    Originally designed to treat diabetes, these drugs mimic a hormone that slows digestion and induces a feeling of fullness. As a result, GLP-1 users not only eat less but are also moving away from processed foods. This shift has significant implications for convenience stores, as many popular products—such as energy drinks, beef jerky, beer, and candy—are being abandoned by GLP-1 users.

    Research from Numerator and Cornell University reveals that individuals on GLP-1s spent 11% less on salty snacks within the first six months of using the medication. Dried meat snacks, which generated over $2 billion in annual sales for c-stores in 2023, saw a 17% decrease in spending from GLP users compared to non-users, according to Circana data. Another Circana report found that while GLP-1 users initially spent more at c-stores than non-users, their convenience store spending dropped by 5.2% in the first year of using the medication.

    A year-old forecast predicted that 24 million Americans, or about 7% of the population, would be taking GLP-1s by 2035. However, Circana recently reported that 6% of Americans are already using the drug, with 12% having used it at some point. This growing trend is catching the attention of food manufacturers, grocers, and other companies, prompting convenience store retailers to reconsider their offerings in response to the GLP-1 impact.

    Keto vs. Mediterranean Diet: Which is Better for Blood Sugar Control, Gut Health, and Weight Loss?
    A recent small-scale study compared the effects of a ketogenic (keto) diet to a Mediterranean diet on blood sugar control, gut health, and weight loss in people newly diagnosed with type 2 diabetes. The keto diet showed more immediate benefits, including improved blood sugar levels, gut microbiota composition, body mass index (BMI), and waist circumference, particularly in the short term. However, these advantages diminished after six months, and by the end of the year-long study, both diets resulted in similar improvements in participants' health.

    The keto diet, which involves significantly reducing carbohydrates to encourage the body to burn fat for energy, has been effective for weight loss but is associated with several potential adverse effects, especially when used long-term. In contrast, the Mediterranean diet promotes a more balanced approach to eating, focusing on nutrient-rich foods and healthy fats.

    Participants in the study, aged 45 to 65, were obese individuals who had recently been diagnosed with type 2 diabetes and had not yet started medication. The study, which initially involved 11 participants, assigned them to either a very low-calorie ketogenic diet (less than 30 grams of carbs per day) or a Mediterranean-style diet. By the end of the study, only eight participants completed the full trial.

    The results suggest that while the keto diet may provide short-term improvements, its long-term sustainability and safety remain concerns.

    The Role of Fermented Foods in Combating Cognitive Decline
    Fermented foods are created through the interaction of food and microbial enzymes, producing unique compounds absent in natural food items. Initially valued for preservation, these foods are now celebrated for their health benefits, with some experts advocating their inclusion in dietary guidelines. A significant health concern today is the rising prevalence of cognitive decline and dementia, exacerbated by an aging global population. Research indicates a link between type 2 diabetes and an increased risk of Alzheimer's disease, a condition that results in severe brain degeneration. Early intervention to prevent mild cognitive impairment (MCI) is essential to reducing the risk of dementia. Nutrients found in common foods, such as dairy products, are believed to help lower the risk of Alzheimer's disease. Camembert cheese, produced from milk fermented with white mold, may enhance brain health in older adults by boosting certain brain-supportive factors. While promising, the precise compounds and mechanisms behind these benefits remain unclear.
