Feeling Tired, Bloated, or Out of Balance? Your Liver Might Be the Missing Link 

Join LifespanMD’s Registered Dietitian, Keren Reiser, at a free upcoming event hosted by the Canadian Digestive Health Foundation, where she’ll dive into the often-overlooked condition MASLD - Metabolic dysfunction-Associated Steatotic Liver Disease - the most common chronic liver disease in Canada and worldwide. Many people experiencing chronic fatigue, digestive discomfort, and uncontrollable cravings chalk it up to aging or stress, but these may actually be early warning signs of MASLD, a disease driven by metabolic imbalances like insulin resistance, high blood sugar, excess abdominal fat, and diets high in ultra-processed foods. MASLD can impact people of all body types and often remains undetected until serious damage occurs. At LifespanMD, we believe in getting to the root cause of chronic symptoms - not just managing them - and this free session is a chance to learn the science and practical strategies behind liver health, fatigue, cravings, and digestive wellness.
