    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

    The Impact of Fat Distribution on Heart Disease Risk
    Heart disease remains the leading cause of death in the United States, accounting for one in five fatalities. While several conditions, such as high blood pressure, high cholesterol, diabetes, overweight, and obesity, are known to elevate the risk of heart disease, recent research suggests that fat distribution within the body also plays a critical role, even for individuals with a healthy weight.

    A study published in the European Heart Journal by researchers from Brigham and Women’s Hospital and Harvard Medical School revealed that intramuscular fat, or fat stored within muscle tissue, significantly increases the likelihood of serious heart disease, regardless of other traditional risk factors or body mass index (BMI).

    The Centers for Disease Control and Prevention (CDC) emphasize that heart disease is the leading cause of death across most ethnic groups in the U.S. Globally, it accounts for one-third of all deaths, affecting low- and middle-income countries as well as affluent ones.

    Several factors contribute to the risk of developing heart disease. These include high blood pressure, elevated levels of LDL (low-density lipoprotein) cholesterol, tobacco use, physical inactivity, high alcohol consumption, obesity, and diabetes. To mitigate these risks, the CDC recommends maintaining a healthy weight, eating a diet rich in fiber and low in saturated and trans fats, engaging in regular physical activity, and avoiding smoking.

    This emerging research highlights the importance of not only focusing on overall body fat but also understanding its distribution, as intramuscular fat could independently heighten heart disease risk.

    Exploring the Pros and Cons of GLP-1 Agonists: Weight Loss, Cognitive Benefits, and Health Risks
    The use of glucagon-like peptide-1 receptor agonists (GLP-1 agonists), such as Ozempic, Wegovy, Mounjaro, and Zepbound, for weight loss has been on the rise. Originally developed to manage type 2 diabetes, these medications have become popular for their potential to support weight loss.

    Recent studies highlight both positive and negative side effects of GLP-1 medications. While they are associated with benefits like improved cognitive and behavioral health, including a reduced risk of addiction, they also carry risks such as pancreatitis, gastrointestinal problems, kidney issues, gastroparesis, and bowel obstruction.

    For instance, research published in October 2023 revealed a connection between GLP-1 drugs and an increased likelihood of pancreatitis and digestive tract conditions. Conversely, other studies suggest these medications may reduce risks of cardiovascular disease and dementia, offering significant potential for broader health benefits.

    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.
