Why Trump’s leg swelling could be a warning sign for millions | ScienceDaily
President Trump s diagnosis of Chronic Venous Insufficiency (CVI) has brought renewed attention to a frequently overlooked yet dangerous condition. CVI affects the ability of veins especially in the legs to return blood to the heart, often leading to swelling, pain, skin changes, and ulcers. The American Heart Association warns that CVI isn t just a cosmetic issue; it's strongly linked to cardiovascular disease and increased mortality, even when other risk factors are accounted for. Seniors, smokers, those with sedentary lifestyles, and people with obesity are particularly at risk.
This gut hormone could explain 40% of IBS-D cases—and lead to a cure | ScienceDaily

How a hidden brain circuit fuels fibromyalgia, migraines, and PTSD | ScienceDaily
What if your brain is the reason some pain feels unbearable? Scientists at the Salk Institute have discovered a hidden brain circuit that gives pain its emotional punch—essentially transforming ordinary discomfort into lasting misery. This breakthrough sheds light on why some people suffer more intensely than others from conditions like fibromyalgia, migraines, and PTSD. By identifying the exact group of neurons that link physical pain to emotional suffering, the researchers may have found a new target for treating chronic pain—without relying on addictive medications.
Acid-busting diet triggers 13-pound weight loss in just 16 weeks | ScienceDaily
Swap steaks for spinach and you might watch the scale plummet. In a 16-week crossover study, overweight adults who ditched animal products for a low-fat vegan menu saw their bodies become less acidic and dropped an average of 13 pounds—while the Mediterranean diet left weight unchanged. Researchers link the shift to lower “dietary acid load,” a hidden inflammation trigger driven by meat, eggs, and cheese.

Myth-busting study shows controversial seed oils reduce inflammation | ScienceDaily
A new study is turning heads by challenging the popular belief that seed oils are harmful to health. Researchers analyzed blood markers from nearly 1,900 people and found that higher levels of linoleic acid — an omega-6 fat commonly found in seed oils — were linked to lower inflammation and better cardiometabolic health. The study used direct biomarkers instead of diet surveys, making its findings more robust. These results support a growing body of evidence that seed oils, far from fueling disease, may actually help protect against heart disease and type 2 diabetes.
Maternal depression can lead to children's emotional overeating, study shows | ScienceDaily
Up to 25% of new mothers suffer from postpartum depression, which can significantly impact their parenting behavior and the wellbeing of their children. A new study looks at long-term effects of early maternal depression on children, underscoring the need to provide adequate support for mothers who might be struggling.
Beyond the gut: A new frontier in IBS treatment by targeting the brain | ScienceDaily
Irritable bowel syndrome (IBS) is a common digestive disorder with unclear causes, affecting about 10% of the global population. Researchers have now discovered that opioid delta-receptor agonists may alleviate IBS symptoms by acting directly on the central nervous system. Using a novel stress-induced mouse model, they found these drugs reduce abdominal pain and regulate bowel movements. This research suggests a promising approach to treating IBS by targeting stress as a contributing factor.
Microbiome as a potential key to better treatment: Clinical study on new therapy for Crohn's disease | ScienceDaily
A special liquid diet, known as exclusive enteral nutrition, is an essential therapy for Crohn's disease. Patients consume only this formula for six to eight weeks, completely avoiding solid foods. However, the exact reasons why this is helpful were previously unclear. Researchers have now been able to decipher the mechanism behind this dietary therapy.
A light-activated drug to fight psoriasis | ScienceDaily
Psoriasis is a chronic skin disease that manifests itself mainly with skin symptoms (dryness, itching, scaly skin, abnormal patches and plaques). It affects about 2% of the population and is mediated by an altered immune system response that triggers the proliferation of skin cells. Depending on the severity, there are different therapeutic options (topical medications, phototherapy, systemic drugs, etc.), but some conventional treatments can have harmful effects on patients.
After cardiac event, people who regularly sit for too long had higher risk of another event | ScienceDaily
