Ozempic, Wegovy could reverse severe liver disease, study suggests
(NewsNation) — Drugs made to treat diabetes and weight loss could stop or even reverse a severe liver disease, according to a new study.
The international study led by a Virginia Commonwealth University researcher found the medication semaglutide, commonly known by brand names Ozempic and Wegovy, has the ability to counter metabolic dysfunction-associated steatohepatitis, or MASH, liver disease and some of its risk factors.
MASH is characterized by inflammation and scarring caused by fat buildup in the liver. It affects roughly 20% of adults in the United States and is closely associated with risk factors like Type 2 diabetes and high blood pressure, according to the Cleveland Clinic.
These 2 things in your diet could help lower inflammation: Study
Researchers administered weekly injections — either a placebo or semaglutide — to 800 patients across 37 countries between 2021 and 2023.
More than half of participants had Type 2 diabetes, and 75% were obese.
After nearly 17 months of injections, 62.9% of semaglutide patients had less inflammation and fat accumulation in their livers; 34% of placebo patients saw the same results.
Semaglutide also reduced liver scarring in 37% of patients, compared to the placebo's 23%.
The study's semaglutide subjects also saw 10.5% weight loss, as well as improvements in liver enzymes and liver fibrosis measurements.
How are hypertension, heart disease and stroke related?
Lead author Dr. Arun Sanyal said the study could offer a 'promising new approach for millions of patients.'
'If approved, this could offer an additional therapeutic option for patients with MASH and fibrosis,' Sanyal said. 'This is crucial, given the strong link between MASH and cardiovascular, metabolic, and renal conditions, where semaglutide has already shown established health benefits.'
Sanyal's team plans to continue the research by studying 1,200 participants from 37 countries for up to five years to look into long-term liver issues.

Drop in fentanyl seizures at border suggests enforcement working
(NewsNation) — For years, a rise in border trafficking of illegal drugs, including fentanyl, led to one of the most dangerous epidemics in U.S. history, but new data suggests the worst may be behind. Last year, the U.S. Border Patrol seized more than 1,700 pounds of fentanyl per month compared to only 746 pounds a month so far this year. That's a drop of more than one half, if the pace holds. U.S. seizures have decreased by 30% at the border compared with the same period last year, the Washington Post reported. A source in Mexico tells NewsNation the drop in fentanyl seizures indicates the U.S. government has been successful in putting pressure on its neighbor to the south to crack down on fentanyl production. Mexican president asks China for help in fight against fentanyl The Trump administration has made fentanyl trafficking a national security issue and has threatened Mexico with tariffs. Mexican President Claudia Sheinbaum responded by deploying 10,000 troops to her country's northern border. The two countries are also cooperating in the field. U.S. authorities worked alongside Mexican federal agencies to dismantle three large-scale synthetic drug production labs in Sinaloa, Mexico, a stronghold for the Sinaloa Cartel. The cooperation adds new pressure on cartels to produce less of the synthetic opioid so that they can avoid the attention of the U.S. government. U.S. Rep. Dan Crenshaw, R-Texas, recently praised Mexico for busting a fentanyl super lab that was producing 2 tons of the drug each week. The lab was dismantled, and authorities seized $80 million in product. Another factor in the drop in fentanyl seizures: The Sinaloa Cartel is involved in a civil war between two factions. Even with the tide turning at the border, fentanyl remains cheap and widely available in the United States. Copyright 2025 Nexstar Media, Inc. All rights reserved.

June marks CPR and AED Awareness Month
(WKBN) — June is CPR and AED awareness month. If you don't know CRP, now is a good time to learn, because emergencies can happen at any time. Some people may feel scared to help during an emergency, but not helping can be worse. First, check the person's pulse and see if they are breathing. If they aren't, start CPR right away. It's recommended to push hard and fast with 100 to 120 chest compressions per minute. You don't need to do mouth-to-mouth breathing. Dr. Nicholas Ruthmann, a cardiologist from the Cleveland Clinic, says if there's an AED, you should use it. 'There's incredible data that delays in CPR will actually change the outcome quite considerably for a patient, and conversely, if you can intervene within those first few minutes, even, the chances of that patient actually having a survival skyrocket,' Ruthmann said. Reports show most cardiac arrests happen at home, which is why Ruthmann says it's very important to know CPR. Copyright 2025 Nexstar Media, Inc. All rights reserved.

62% of Women Don't Know This Important Heart Health Fact, a Cleveland Clinic Cardiologist Warns
Heart disease is the leading cause of death for women. But many don't realize this fact, or simply don't think they're at risk. A new national survey of women in the U.S. by Cleveland Clinic, in collaboration with YouGov, found that 62% of women don't know that heart disease affects men and women at similar rates. For decades, health experts have been working to raise awareness about women and heart disease, but more work needs to be done, says , a cardiologist at Cleveland Clinic. 🩺SIGN UP for tips to stay healthy & fit with the top moves, clean eats, health trends & more delivered right to your inbox twice a week💊 'Women are fixated on breast cancer and gynecological cancer—and those are very, very important—but the sad truth is that a majority of women will die from heart disease,' she adds. 'So, it's really important to keep on educating.' Heart disease was responsible for one in five female deaths in the U.S. in 2021, according to the Centers for Disease Control and Prevention. The good news is that in many instances, you can lower your risk for heart disease. Here's what you should know. The Cleveland Clinic survey highlighted a few barriers that affect women's health and access to health care. Cost is a big one—most women surveyed said the cost of health care, healthy foods and exercise keep them from prioritizing their health. A third listed stress and anxiety, and 14% said caregiving responsibilities were challenges. Related: This Habit May Make You Six Times More Likely to Have a Heart Attack'Those barriers are very real, and we see them all the time,' Dr. Cho says. Women in their 40s, 50s and 60s, known as the 'sandwich generation,' are typically caring for their parents and children, and may neglect their own needs. Food costs are rising, and healthy foods are typically more expensive than unhealthy items, research shows. Many Americans also live in food deserts, where they don't even have access to healthy foods. Checking out local food pantries or other local resources could help. When it comes to exercise, there are many free options out there. 'We often think we need money for exercise, but we don't need any money for exercise,' Dr. Cho says. She recommends tapping into the many free workout videos on YouTube or starting to walk. It's important to start monitoring your blood pressure and other aspects of your cardiovascular health now, Dr. Cho says. As you get older, your blood pressure usually goes up, so getting a baseline and paying attention to changes is crucial. If you're healthy overall, you should get your cholesterol and glucose levels checked every couple of years (or more often if you're at a high risk for heart disease), Dr. Cho says.

Most cases of heart disease are preventable, meaning you can lower your risk factors, Dr. Cho says. 'That's the great news,' she says. 'So, how do you do that? You do that by not smoking. You do that by eating healthy, exercising and getting your blood pressure checked, your cholesterol checked, making sure you are not diabetic, and that you know your family risk. Those are the important bottom-line things.' Related: 3 Subtle Signs of Heart Attack Risk Most People Miss, According to a Doctor Along with quitting smoking and keeping up with your health screenings, here are some tips to lower your risk, according to the American Heart Association: Many women have at least one condition, such as high blood pressure, high cholesterol, diabetes or a family history. Women with 'adverse pregnancy outcomes,' such as gestational diabetes, high blood pressure and other conditions during pregnancy, may have a higher risk of developing heart disease later, Dr. Cho says. Nausea, lightheadedness, shortness of breath, fatigue, cold sweats, or aches or tightness in your chest, arms, back, neck, jaw or abdomen are symptoms women might experience. Choose lots of fruits, vegetables, whole grains, fish, low-fat dairy and skinless poultry. Limit ultra-processed foods, sugar, saturated fat, red meat and sodium. Strive to get at least 150 minutes of moderate-intensity aerobic activity a week or 75 minutes of intense activity or a combo. Add in strength training two or more days a week. It's never too early or too late to take care of your heart, Dr. Cho says. 'I desperately want women to know that the number one killer for women is heart disease. You can reduce your risk, and risk factors are preventable.'
