The American Heart Association (AHA) and the American College of Cardiology (ACC) have just released their first major update to blood pressure management guidelines since 2017. These new recommendations go beyond simply telling you what numbers to aim for, they focus on prevention, early intervention, and more personalized care across your entire lifespan.

High blood pressure (hypertension) is one of the biggest risk factors for heart disease, the world’s leading cause of death, as well as kidney disease, stroke, type 2 diabetes, and even dementia. With nearly half of all U.S. adults having higher-than-normal blood pressure, these new guidelines are significant for millions of people.

Blood Pressure Targets Remain the Same

One thing that hasn’t changed in 8 years, is how high blood pressure is defined. The cutoff points are still the same as they were in 2017:

• Normal: Less than 120/80 mm Hg
• Elevated: 120–129 mm Hg systolic and under 80 mm Hg diastolic
• Stage 1 Hypertension: 130–139 mm Hg systolic or 80–89 mm Hg diastolic
• Stage 2 Hypertension: 140 mm Hg or higher systolic, or 90 mm Hg or higher diastolic

Your blood pressure reading has two numbers:

The top number (systolic) measures the pressure when your heart pumps, while the bottom number (diastolic) measures it when your heart is at rest.

More Aggressive Early Intervention

While the numbers haven’t changed, how doctors treat them has. The new guidelines recommend starting with healthy lifestyle changes, like eating better, exercising, and reducing salt, for anyone with readings in the 130–139 range. If those changes don’t work after three to six months, medication may be prescribed earlier than before.

This shift is meant to prevent complications before they start. “We’re aiming to help more people get their blood pressure under control earlier to prevent heart disease, strokes, kidney problems, and even dementia,” said Dr. Daniel W. Jones, chair of the writing committee for the new guidelines.

A Bigger Focus on Weight Loss and GLP-1 Medications

One of the most notable updates involves the use of GLP-1 receptor agonists, such as Ozempic and Mounjaro, which have become popular for weight loss. The guidelines now say that patients who have high blood pressure and are overweight should discuss these medications with their healthcare provider, as losing weight can dramatically improve blood pressure control.

For people with severe obesity, surgery may even be recommended if lifestyle changes and medications are not enough.

New Pregnancy and Postpartum Recommendations

High blood pressure during pregnancy can be dangerous, leading to complications such as preeclampsia, which can threaten both the parent and baby. The new guidelines recommend that pregnant and postpartum individuals with stage 2 hypertension start on certain medications to lower the risk of complications. This is an important shift, as research shows pregnancy-related hypertension can have lasting effects on cardiovascular health.

The Brain Connection: Dementia Risk

Another significant addition to the 2025 guidelines is the acknowledgment of the link between high blood pressure and cognitive decline. New research shows that hypertension can reduce blood flow to the brain, leading to memory issues and an increased risk of dementia. By controlling blood pressure early, the hope is to preserve cognitive function later in life.

The PREVENT Risk Calculator

Doctors are now encouraged to use a new tool, called PREVENT, to estimate a patient’s risk of developing heart disease over the next 10 and 30 years. This calculator considers multiple factors: age, sex, cholesterol levels, blood pressure, and more, to create a personalized risk profile and guide treatment decisions.

Alcohol Guidance Tightened

In a change that may surprise many, the updated guidelines now recommend avoiding alcohol entirely if possible. Previous advice allowed for one drink per day for women and two for men, but growing evidence shows even moderate alcohol intake can raise blood pressure. For those who still choose to drink, the AHA now advises staying under those older limits.

Lifestyle Changes Are Still the Foundation

Despite all the new tools and treatments, the cornerstone of blood pressure management remains the same: a healthy lifestyle. The updated recommendations reinforce:

• Following a heart-healthy diet like the DASH plan, rich in fruits, vegetables, whole grains, lean proteins, beans, and nuts
• Reducing sodium intake to less than 2,300 mg per day, ideally aiming for 1,500 mg
• Exercising regularly, with at least 150 minutes of moderate activity weekly plus resistance training
• Managing stress through mindfulness, yoga, or relaxation techniques
• Maintaining a healthy weight, losing at least 5% of body weight if overweight

Why This Matters

High blood pressure is often called the “silent killer” because it has no symptoms but can do significant damage over time. By encouraging earlier treatment, recognizing new links to conditions like dementia, and providing tools like the PREVENT calculator, the 2025 guidelines aim to help people live longer, healthier lives.

“The reality is that the first line of treatment, lifestyle changes, really does work if you commit to it,” Dr. Jones said. “It can be hard in today’s food environment, but the payoff is worth it.”

Stroke remains one of the leading causes of disability worldwide, often leaving survivors with long-term challenges in movement, memory, and speech. Traditional rehabilitation can alleviate symptoms, but progress is slow and limited for most patients. Researchers are now investigating a game-changer, a pill that could stimulate the brain to regenerate itself. Early studies indicate that approved drugs for other diseases can be repurposed to stimulate sleeping repair processes, providing a new avenue for recovery that previously was not possible. Successful use of this method could reframe the way physicians treat stroke victims and transform the future of neurorehabilitation.

For years, doctors and scientists knew that if damaged, the brain had little to no regeneration capacity. Stroke victims and head injury patients were too often doomed to a lifetime struggle with dysfunctional movement, memory loss, or difficulty speaking. Today, new research contradicts the long-standing principle. A pill in development may activate the brain's ability to heal itself, giving hope to millions of people around the globe.

Strokes, which happen as a result of interrupted blood flow to areas of the brain, continue to be among the major causes of long-term disability. Brain cells are killed through the resulting damage, and survivors are left with physical and mental difficulties that are notoriously hard to reverse. Conventional rehabilitation involves physical therapy and changes in lifestyle, but gains are slow and partial.

"Previously, the medical community believed that adult brains were incapable of producing new neurons after severe damage," describe neurologists who are knowledgeable about the study. "This pill contradicts that by stimulating directly involved pathways to neurogenesis."

The treatment, which comes from adapting already proven drugs like Maraviroc—already approved for other diseases—is aimed at molecular mechanisms thought to induce the birth of new brain cells and fix faulty circuits. If successful, it may significantly lower reliance on resource-intensive rehab programs.

How Does The Stroke Recovery Pill Work?

At the core of this innovation is the capability to "turn on" latent genes that stimulate neural repair. Recent stories in Futurism have reported that researchers, using animal models, have shown that activation of these pathways not only repaired faulty neural connections but also recovered movement and memory.

Initial experiments are exploring whether the same effects are possible in humans. Stroke patients are being treated with controlled quantities of the pill, and scientists monitor changes in brain plasticity, motor function, and cognitive abilities. The potential to restore lost capabilities via medication has generated guarded optimism among scientists.

“The early data is promising, but we’re just beginning to understand the scope of what this drug can achieve,” said one of the study’s lead researchers. “The ultimate goal is to complement or even replace traditional rehabilitation therapies.”

Optimism there is, despite challenges. Converting animal experiments to human triumphs has long been filled with stumbling blocks. Results vary considerably from person to person based on the magnitude of the brain injury and how quickly postinjury care is initiated.

Existing trials, some of which are closely monitored by The New York Times, are intended to test both safety and efficacy. Though Maraviroc has an established record of safety in its current uses, application to brain repair introduces new risks. Overactivating brain function, for instance, may precipitate seizures or other unexpected side effects.

Regulatory agencies such as the FDA are keeping close tabs. Any such breakthrough therapy will need to meet strict safety criteria before becoming widely available. Experts warn that although the prospect of a pill that can restore lost brain function has revolutionary appeal, the only course is thorough testing.

How Does The Pill Impact Brain Healing and Health?

The potential for this research goes far beyond recovery from stroke. Traumatic brain injuries caused by automobile accidents, sports injuries, or war may someday be cured with similar regenerative approaches. Researchers are also investigating whether stimulating neurogenesis could help degenerative diseases like Alzheimer's or Parkinson's disease.

New Atlas reports indicate that marrying molecular therapies with current medical devices might optimize the recovery. For instance, Stanford researchers developing clot-removing technology envision a future when physical interventions are wedded with drugs that activate the brain's inherent repair function.

The drugs industry is already monitoring the situation. With millions globally suffering from neurological conditions, the potential is huge. However, experts stress that scientific support, rather than commercial motives, should be the driving force behind the development.

For patients, a chance at a pill that will trigger brain regeneration is nothing less than revolutionary. Consider a stroke victim able to walk without a decade of agonizing therapy, or a college athlete recovering from a head injury without enduring deficits.

But whereas the promise is revolutionary, neurologists caution patience. "We're in the beginning stages," said one clinical scientist. "The science is good, the trials have started, but it will take years to be sure if this is the tipping point we all hope it will be."

The economic stakes are equally high. Stroke rehabilitation alone costs billions annually in healthcare expenses. If a pill could accelerate recovery and reduce long-term dependency, it could reshape not only medicine but healthcare systems globally.

The road from bench to bedside is long, but hopefully, it is getting shorter. A placebo-controlled, randomized trial in Canada is ongoing, and the last results are likely to be available in approximately two years. Those results will give more definite answers on whether or not brain regeneration via medication is indeed achievable.

A convenience that has become a staple in many homes, ready-to-eat, subscription-based meal kits has come under scrutiny after the Centers for Disease Control and Prevention (CDC) linked certain products from Metabolic Meals to a multistate Salmonella outbreak. At least 16 individuals across 10 states have fallen ill so far, seven of whom were hospitalized, and health officials warn the numbers could be higher in the weeks ahead.

The CDC reports that at least a dozen individuals have fallen sick and seven were hospitalized after eating meal delivery kits suspected to be contaminated with Salmonella. Health officials are still tracing the exact source of contamination, but preliminary results indicate that poor handling and storage of foods could have contributed. Why this is problematic is that meal kits are promoted extensively as safe, fresh, and convenient, with many regarding them as a healthier option compared to fast food. This outbreak points to the underlying dangers associated with ready-to-eat deliveries, presenting timely questions on food safety inspections, supply chain cleanliness, and consumer education.

How the Outbreak Was Traced to Meal Delivery Kits?

The CDC released that the outbreak was associated with meals served during the week of July 28, with four individual types identified:

• Four Cheese Tortellini with Pesto Sauce and Grilled Chicken — Lot Code: 25199; Best By: 08/07/2025
• Low Carb Chicken Teriyaki and Vegetables — Lot Code: 25202; Best By: 08/05/2025
• Black Garlic & Ranch Chicken Tenders with Roasted Vegetables — Lot Code: 25205; Best By: 08/08/2025
• Sliced Top Sirloin with Roasted Peanut Sauce and Summer Vegetables — Lot Code: 25203; Best By: 08/06/2025

Further codes under investigation are 25199, 25202, 25203, 25204, and 25205.

Metabolic Meals, the "macro-friendly" meal service subscription company, has admitted to the problem and is working with authorities. Under a statement released by the CDC, customers who bought the affected meal types were called individually and told not to eat the products.

What Salmonella Does to the Body?

Salmonella is among the United States' most prevalent foodborne pathogens and causes an estimated 1.35 million infections and 26,500 hospitalizations each year, as per CDC statistics. Symptoms of infection usually manifest between six hours to six days after infection and can include:

• Diarrhea (occasionally with blood)
• Nausea and vomiting
• Abdominal cramps
• Fever and chills

Most people recover without medical treatment in four to seven days, but vulnerable groups—including children under five, adults over 65, and those with weakened immune systems—are at higher risk for severe illness requiring hospitalization. In rare cases, Salmonella can spread beyond the intestines, leading to life-threatening complications such as endocarditis, arterial infections, or arthritis.

First Signs of Salmonella Poisoning to Spot

Public health officials highlighted that the initial symptoms of infection tend to be sudden diarrhea, fever, and cramping. Consumers who have just consumed contaminated Metabolic Meals and experience these symptoms should immediately seek medical consultation. Warning symptoms that need immediate medical attention are:

• Fever of more than 102°F
• Diarrhea persisting for more than three days without improvement
• Bloody stools
• Severe dehydration with dizziness, dry mouth, or decreased urination
• Recurrent vomiting that makes fluid intake difficult

How Widespread Is the Salmonella Outbreak?

The illnesses have been reported in California, Missouri, Georgia, Minnesota, Texas, Arkansas, Illinois, Rhode Island, Wisconsin, and Washington. The actual number of cases is probably higher, health authorities warn, as many people recover without being tested or are unaware that their illness is part of a foodborne outbreak.

To date, no deaths have been reported.

Salmonella Outbreak: What Consumers Should Do?

The CDC asks anyone who has contaminated meals in their fridge or freezer to dispose of them immediately or call Metabolic Meals for instructions. Affected products should not be tested "to determine if they're safe." Consumers also should:

Hand-wash, kitchen surfaces, and utensils that were in contact with the meals with hot, soapy water or a dishwasher.

Prevent cross-contamination by washing refrigerator shelves and storage containers in which the affected products were stored.

Watch for symptoms closely for as long as six days following possible exposure.

Why Meal Kits Pose Unique Risks?

Meal kits have grown extremely popular, and they provide convenience for busy families and individuals. However, with the centralized production and shipping method, if contamination takes place at the source, thousands of meals are delivered across several states within days.

Food safety specialists point out that despite rigorous quality assurance, pathogens such as Salmonella can penetrate even during preparation, packaging, or transportation. Since these foods are ready-to-eat or need little handling, consumers tend not to cook them at high enough temperatures to destroy bacteria.

This outbreak follows in the wake of another outbreak involving Salmonella: in recent times, almost 100 cases in 14 states were traced back to contaminated eggs. The two outbreaks in rapid succession underscore the continued issues in food safety monitoring and regulation in the age of mass-produced, convenience foods.

Experts emphasize that outbreaks cannot always be prevented but that rapid detection and communication, as demonstrated by the CDC response, are essential for preventing spread and minimizing hospitalizations.

The exact point of contamination during Metabolic Meals' manufacturing process is still under investigation. Public health investigators are looking into whether the contamination occurred during raw ingredients, food handling, or packaging and distribution.

Until further information is available, the CDC still recommends against eating contaminated meals and will update information as the investigation unfolds.

The World Health Organization (WHO) has, for the first time, added GLP-1 receptor agonists, popularly known as the active ingredients behind weight loss drugs like Ozempic and Wegovy to its Essential Medicines List (EML). The move, announced Friday, marks a turning point in the global conversation about diabetes, obesity, and equitable access to life-saving treatments.

The Essential Medicines List is one of WHO’s most influential public health tools. Updated every two years, the list identifies medicines that should be available in every functioning health system, regardless of a country’s income level. It now includes 523 medicines for adults and 374 for children. Adoption is widespread: over 150 countries use the EML as a reference point for drug procurement, health insurance coverage, and treatment guidelines.

By including GLP-1 receptor agonists such as semaglutide (Ozempic, Wegovy), liraglutide, and tirzepatide (Mounjaro), WHO has formally acknowledged their role not just in diabetes management but also in broader health outcomes, particularly cardiovascular and kidney health.

Why the Addition of GLP-1 Drugs is Revolutionary?

GLP-1 receptor agonists mimic a natural hormone that regulates blood sugar and appetite. They stimulate the pancreas to release insulin, slow digestion, reduce liver glucose production, and act on the brain to suppress hunger. This dual benefit—controlling diabetes and supporting weight loss—has propelled them into mainstream awareness.

Scientific evidence reviewed by WHO’s Expert Committee confirmed their ability to lower blood sugar, reduce risks of heart and kidney complications, support weight management, and even extend life expectancy in people with type 2 diabetes and related conditions. For patients with cardiovascular disease, kidney disease, or obesity, these drugs are emerging as game-changers.

The Limits of the Decision

It’s important to note that while GLP-1s are popularly associated with weight loss, WHO stopped short of endorsing them for obesity alone. The drugs were added specifically for adults with type 2 diabetes mellitus who also have established cardiovascular disease, chronic kidney disease, or obesity.

This distinction matters. While obesity affects over one billion people worldwide, WHO’s cautious stance reflects the still-limited long-term data on safety, sustainability of weight loss, and cost-effectiveness in populations without diabetes.

Barriers to Access

Affordability remains the biggest hurdle. Médecins Sans Frontières (MSF) called the decision a “critical milestone” but highlighted that in low-resource settings, GLP-1s are practically out of reach.

A recent MSF study found GLP-1 agonists can cost up to 400 times more than their estimated manufacturing price, while rapid-acting insulin analogues also newly included on the list—are priced 75 times higher than what they could be profitably produced for.

“Rapid-acting insulins and GLP-1s are unaffordable and often unavailable in low-resource and humanitarian settings,” said Elizabeth Jarman of MSF’s Access Campaign. “Countries must act quickly to update national EMLs, plan procurement, and push pharmaceutical corporations to make them affordable.”

WHO echoed this call, urging governments to prioritize patients who would benefit most, support generic competition to drive prices down, and ensure distribution at the primary care level, especially in underserved areas.

Expanding the Scope Cancer Treatment

The 2025 update of the EML goes far beyond GLP-1s. Twenty new medicines were added for adults, alongside 15 for children. Notable inclusions are:

Cancer Immunotherapies: Pembrolizumab (Keytruda) and alternatives atezolizumab and cemiplimab for metastatic cervical, colorectal, and non-small cell lung cancers. These immune checkpoint inhibitors have been shown to prolong survival by four to six months in advanced cancers.

Cystic Fibrosis Therapy: Trikafta (a triple-combination drug by Vertex Pharmaceuticals) was hailed as a “historic breakthrough” by patient advocacy groups, marking the first time a cystic fibrosis-specific therapy made the EML.

Insulin Expansion: Short-acting insulin analogues were added, complementing the long-acting formulas already listed since 2021. This creates a complete set of recommended insulin therapies, critical for tailoring diabetes treatment.

Vaccines and Pediatric Medicines: The children’s list now includes drugs for haemophilia, cystic fibrosis, and newly approved vaccines for malaria and mpox.

Tensions Over Excluded Drugs

Not all proposals made it onto the list. Knowledge Ecology International criticized WHO for excluding risdiplam, a treatment for spinal muscular atrophy (SMA). The drug, they argued, is effective, relatively inexpensive to manufacture, and could transform outcomes for children with SMA.

WHO’s Expert Committee deferred inclusion due to incomplete trial data, though subsequent studies published later in the year showed highly promising results.

How Does The Updated Essential Medicine List Affect Global Health?

The stakes of WHO’s decision are high. Diabetes and obesity are among the most pressing health challenges worldwide. More than 800 million people are living with diabetes, half without treatment, while obesity affects over a billion. These conditions are not confined to wealthy nations; their fastest growth is occurring in low- and middle-income countries.

Including GLP-1s in the Essential Medicines List sends a strong signal to governments, insurers, and pharmaceutical companies: these drugs are not luxury treatments for the wealthy but part of the global standard of care.

Yet the path from inclusion to access is not straightforward. Countries must adopt the drugs into their national lists, negotiate prices, and strengthen health systems to deliver them effectively. As David Reddy, director-general of the International Federation of Pharmaceutical Manufacturers, pointed out, inclusion on the list must be accompanied by infrastructure, diagnostics, and trained professionals.

Cancer treatments remain one of the most tightly scrutinized areas of the EML. Cancer kills nearly 10 million people each year, accounting for one in three premature deaths from non-communicable diseases. Despite the flood of new cancer drug approvals in recent years, WHO only recommends therapies that demonstrate clear survival benefits of at least four to six months.

The inclusion of pembrolizumab and its alternatives reflects both clinical evidence and a deliberate effort to reduce global inequities in cancer care. Still, the high cost of immunotherapies poses a major barrier. Without mechanisms like tiered pricing and voluntary licensing, poorer countries may struggle to make these life-extending drugs widely available.

The 2025 Essential Medicines List reflects both optimism and realism. On one hand, it celebrates remarkable advances in science—from GLP-1s reshaping diabetes care to breakthrough therapies for cystic fibrosis and cancer. On the other, it acknowledges the sobering reality of cost and access.
