The blood group you belong to is more than just a marker to match your donation; it may have something telling you about your probability of acquiring certain diseases. A new study published in the Journal of Neurology notes that it can be made an assumption from your blood group by which you are most likely to have an early-onset ischemic stroke at the age under 60.

Although the factors like genetics, age, and lifestyle are the factors that best contribute to the risk of a stroke, this new research has really shed new light on how blood group can be considered as playing a pivotal role than ever thought.

How Your Blood Type links to Stroke Risk?

A study suggests that an independent relationship exists between blood type A and an elevated risk for an early-onset ischemic stroke. Ischemic strokes are the presence of a blood clot in one artery, which causes blockage of blood flow to the brain, and about 90% of all stroke cases. The CDC suggests that in the United States, someone has a stroke every 40 seconds while one person dies from a stroke every 3.5 minutes.

This new research, hence, opens the possibilities that an earlier incidence of ischemic stroke in youth could be attributed to blood type A.

But it's worth remembering that blood type is just one of hundreds of risk factors, according to co-author Braxton Mitchell, PhD, MPH, a genetic epidemiologist at the University of Maryland School of Medicine. "In the grand scheme of things, it's a much smaller risk factor than others," he said. Other genetic, environmental, and lifestyle factors still determine stroke risk.

Blood Type A: Strong Link to Early-Onset Stroke

Study authors conducted a genome-wide association analysis, recruiting nearly 17,000 patients with stroke aged 18 to 59 years from 48 studies and more than 599,000 controls who never had a stroke history. The analysis was aimed at exploring genetic variants throughout the human genome in greater detail.

The ABO blood group possessed genetic differences, and the blood type A was the strongest risk factor for a stroke that occurred early in life. The possibility of having an early onset ischemic stroke was 18% higher among people with blood type A compared to the rest of the blood groups. Such a high risk could be associated with a higher susceptibility to blood coagulation, which is one of the most common causes of ischemic strokes.

Blood Type O: Lower Stroke Risk

On the other hand, individuals with type O blood have a 12% reduced risk of an early-onset stroke compared to other blood types. This is in-line with earlier research that has found people with type O blood are more likely to be at low risk for blood clotting inside their arteries, which could be the reason why their overall risk of having a stroke decreased.

Blood Type B and AB: Mixed Bag

Another blood group-the research looked at blood group B-for which a weak association is found with the onset of early and late stroke. However, the authors indicate that when sex and other risk factors are adjusted, no association between blood group B and increased stroke risk exists. In persons with blood group AB, there is no significant association discovered for having an elevated stroke risk.

Other Risk Factors

While this study points to the effect of blood type, it is important to understand that blood type alone is not a strong predictor of stroke risk. Many other factors are comprised in this, including lifestyle, and most importantly, underlying health conditions. Age is one critical factor. According to the CDC, your risk for stroke doubles with each decade after age 55.

While strokes are more likely to affect people who are 65 years of age and older, one in seven strokes strikes people aged 15 to 49.

Thirdly, gender another factor that has been related to increased risks of stroke conditions. The female population is more prone to stroke compared to the male population and tends to have a worse outcome in terms of disability and death due to stroke.

It was recently indicated in the 2022 study that young women aged between 35-45 years had a 44% increased risk of ischemic stroke as compared to men aged between 35-45 years. Perhaps pregnancy or the use of birth control could be some of the factors behind the usual increased risk in women.

Ways You Can Manage Stroke Risk

While the study does show a genetic element linked to blood type and stroke, other controllable factors are more important risks for stroke. Here are some steps you can take to reduce your total risk:

1. Control Blood Pressure: High blood pressure forms one of the most dominant risks for strokes. Control through regular monitoring, medication if required, and lifestyle modifications can prove to reduce this significantly.

2. Maintain a Healthy Weight: Being overweight increases the risk of stroke. Anyone can benefit from staying at a healthy weight and living a healthy lifestyle. A balanced diet and regular exercise can help you achieve and maintain a healthy weight and thus minimize your risk for stroke.

3. Reduce Alcohol Intake and Quit Smoking: Too much alcohol drinking and smoking are also significant risk factors for stroke. Cutting down on alcohol consumption and quitting smoking would be two very important lifestyle changes for anyone interested in being healthy.

4. Stay Physically Fit: Exercise is known to keep the heart healthy, reduce blood pressure, and promote a healthy weight all of which contribute to a decrease chance for stroke.

5. Monitor Your Cholesterol: It's a fact that high cholesterol builds up plaques in arteries, thereby increasing the chances of stroke occurrence. Fruits, vegetables, whole grains, and lean proteins are part of a heart-healthy diet that helps keep cholesterol at bay.

This research thus brings forward a new and enlightened perspective of the correlation between blood type and stroke risk, especially in younger ages. Although type A blood might have a propensity for developing early ischemic stroke, it is worth noting that this is just one of many factors responsible for developing a stroke.

Focusing on controllable lifestyle factors such as remaining within a healthy weight range, staying active, and managing blood pressure will help significantly reduce the chances of having a stroke regardless of the blood type.

New advice from the NHS suggests that people who stop taking weight-loss drugs like Wegovy and Mounjaro should have check-ups for at least a year. The main reason for this is that it's very common for people to gain most of the weight once they stop the medication.

The guidance from NICE (National Institute for Health and Care Excellence) emphasizes that managing weight is a long-term effort, not a quick fix. Patients need extra help and a clear plan to maintain their new weight, which includes habits like eating healthy food and being physically active.

Clinical trials show that people on these drugs often regain a lot of the weight they lost. For example, a trial for Wegovy found that patients put back on about two-thirds of their lost weight after they stopped the injections. It was a similar story for those who took Mounjaro.

Professor Jonathan Benger from NICE explained that the time right after stopping treatment is very important. He said people need "structured support" to keep up the healthy changes they've made. The new advice encourages patients to create healthy habits, use tools to monitor their own weight, and get support from family, friends, and online groups.

Why Are Weight Loss Drugs Popular in UK?

Obesity affects about one in four adults in England. While an estimated 1.5 million people in the UK are using these weight-loss jabs, most are paying for them privately and won't get this NHS support.

Wegovy is available on the NHS for a period of two years for those who have health problems because of their weight and have a high BMI. The drug Mounjaro is expected to be offered to about 240,000 people over the next three years, and there's no set time limit for how long they can take it.

Both drugs work by reducing a person's appetite. They are given along with programs that help people make healthy changes to their diet and exercise habits.

Does Mounjaro Work For Everyone?

The UC Health explains that currently Mounjaro is approved for people with diabetes, not for those who are overweight or obese without diabetes. There is still a lot we have to learn about Mounjaro and researchers are working on the same. A big question that everyone who wishes to start on the weight loss drug are thinking about is whether you will have to keep using the drug forever or can you stop.

To maintain the weight loss achieved with Mounjaro, you will likely need to keep taking the medication indefinitely.

If you lose a significant amount of weight with Mounjaro, Wegovy, or Ozempic, you will likely need to continue taking the medication to keep the weight off. People who have stopped taking Ozempic and Wegovy have typically regained the weight they lost.

As one UC Health expert noted that if you stop taking these medications, and don’t change your behaviors, then the weight can pile back on. Since Mounjaro is newer, there is less information about long-term use, but the trend is expected to be similar.

“This is a warning specifically for parents” — Influencer Michael Brown recently released a video warning parents as well as others, about a potentially addictive drink that is easily available at gas stations in the US. He detailed how, during a casual visit to the gas station store for a beverage, he was approached by a young boy who asked him to buy ‘Feel Free’ for him. Despite being refused, the kid persisted and even tried lunging for Michael’s wallet, leaving him shaken up.

While paying at the counter, Michael recalled asking the shop cashier what ‘Feel Free’ was, to which she pointed at little blue bottles on the counter. She said people are so addicted to it that sometimes they visit 5–6 times a day to buy it — “It’s addictive and people lose their minds.” A quick look at the comments section of the post, which now has more than 9 million views on Instagram, had many people shocked at the severity of the drink and its consequences. Different healthcare professionals also detailed their experience with patients. “It’s Kratom! Have had patients with seizures because of this and also babies experiencing withdrawal from maternal use during pregnancy. It’s no joke,” commented Dr. Shilpa, MD, Child Neurologist and Development Specialist.

To know how many people are affected or it continues to affect, you do not have to look too far — a subreddit known as QuittingFeelFree, which has 5k members, and QuittingKratom with 52k members, are prime spots to get first-person accounts of people who struggled for years or months with their addictions.

In one of the stories, Jasmine Adeoye from Austin posted on TikTok that just a few months before June 2024, she drank several bottles of Feel Free a day and found that quitting it was not easy.

Last year, the production company of Feel Free also faced lawsuits, however, many people are not aware of the same. CBS News had reported that Botanic Tonics had also faced a class-action lawsuit filed in 2023. The lawsuit alleged that the company's marketing was misleading and targeted individuals with a history of addiction. In a statement, the company said it had "fallen short of the high standards of transparency" and implemented changes like enhanced labeling and age restrictions.

Feel Free and List of Ingredients

One of the main ingredients listed in the ‘Feel Free’ drinks is ground kratom leaves. Now a regular person would think — how bad can leaves be? — and consume the drink, but it’s these same leaves that are risky and can lead to severe addiction.

Native to Southeast Asia, the US Food and Drug Administration explains that it also carries the risk of addiction, seizures, and, in rare cases, death. Since kratom is unregulated in the U.S., some products are sold in highly concentrated forms and may contain contaminants like heavy metals and harmful bacteria.

What Happens with Unregulated Use of Kratom?

The American Addiction Centers detailed how lower doses of kratom could help people increase energy and alertness, while higher doses could produce effects similar to that of opioid drug abuse. They detailed a 7-year study done from 2011–2017. The study pointed out how there were 1,800 calls to poison control centers about kratom, with most of those calls happening in the last two years of that period. Here are some things that can happen with unregulated use of kratom:

Addiction and Withdrawal

While it's not common, long-term and heavy kratom use can lead to addiction. People who stop using it suddenly might experience withdrawal symptoms that feel similar to the flu, such as nausea, vomiting, body aches, and chills.

Lack of Regulation

The FDA has not approved kratom for any use. This means that kratom products are not regulated and can sometimes be contaminated with dangerous substances like heavy metals and harmful bacteria. The FDA has warned consumers not to use kratom and has seized shipments of kratom-containing products.

Mixing with Other Substances

Taking kratom with other drugs or alcohol can be very dangerous. In rare but serious cases, this combination has led to severe side effects like liver damage and even death.

Overdose

Overdosing on kratom alone is very rare. However, when it is combined with other substances, the risk increases. For example, a CDC report linked kratom to 152 deaths in 2016 and 2017, but other substances were involved in 87% of those cases.

Over the past few years, doctors and researchers have noticed a clear pattern: more young adults are being diagnosed with colorectal cancer—those under 50. On the surface, some of this surge can be credited to increased screening, especially following guideline updates that lowered the recommended starting age from 50 to 45. But deeper beneath those screening numbers lies a troubling reality: diagnoses among truly younger adults aren’t solely due to being screened earlier. That means we’re facing a bigger shift, one that demands fresh solutions.

In 2018, the American Cancer Society recommended colorectal cancer screening begin at age 45—five years earlier than before. In 2021, the US Preventive Services Task Force followed suit. Unsurprisingly, this led to a jump in early-stage diagnoses among 45-to-49-year-olds.

ACS data published in JAMA shows a steady increase in screening rates: from 20.8% in 2019 and 19.7% in 2021, rising to 33.7% in 2023 among that age group. A second ACS-led study tracked early-stage diagnosis rates—from 9.4 cases per 100,000 in 2019, to 11.7 in 2021, then 17.5 in 2022. That’s a 50% relative increase between 2021 and 2022. Experts note this trend largely reflects held-back cases being detected earlier thanks to broader testing.

But that doesn’t chalk up the entire story. Colon and rectal cancers have been increasing steadily in younger adults—those under 45—for decades. This early-onset rise began in the mid-1990s and includes late-stage diagnoses—not just early detection.

Who Is Getting Diagnosed?

Doctors stress that while the decline in age recommendations helped some, it doesn’t explain the persistent rise in younger adults. In fact, research suggests annual case increases of 2–2.6% have occurred since 2012 among those under 50. In the 20–39 age group, incidence has been rising by around 1.6% per year since 2004.

More than 20% of colorectal cancer cases now occur in adults under 55—double the rate from the mid-1990s. Alarmingly, this early-onset trend is contributing to colorectal cancer becoming the leading cause of cancer death among younger men and the second-leading cause among younger women.

These are not always lifestyle-driven cases. Many patients are young, active, and with no known family history. As clinicians, many have expressed how unsettling it is to see so many seemingly healthy people presenting with aggressive tumors—and often at advanced stages.

What Might Be Driving This Worrisome Surge?

Researchers are testing multiple theories—but none yet fully explain the rise:

Gut microbe toxins such as colibactin, produced by certain E. coli, are drawing attention. These toxins leave a specific DNA mutation fingerprint in early-onset tumors—over three times more common compared to cancers in older patients. Some studies suggest 15% of early-onset cases involve colibactin-driven mutations.

Diet- and lifestyle-related risks remain central: obesity, processed meats, low-fiber diets, sedentary behavior, refined sugar, insufficient sleep, and environmental pollutants. One prominent study links higher birth and adolescent BMI with increased colon cancer risk later in life. Even every additional kilogram at birth above normal is tied to 9% higher colorectal cancer risk.

Other suspected contributors include microplastics, antibiotic use, and artificial light exposure, although more conclusive evidence is pending.

Symptoms You Should Never Ignore

Crucial to stopping this trend early is awareness. Here’s what to watch for—and not dismiss, even if you’re under 45:

• Rectal bleeding
• Persistent abdominal pain or cramping
• Changes in bowel habits or stool shape
• Unexplained weight loss or appetite changes

Jessica Star of ACS—lead author on both new JAMA papers—warns, more than half of cases in younger adults occurred in those not yet eligible for screening. So symptoms matter, regardless of age. If you're dismissed with a benign diagnosis like hemorrhoids, consider a second opinion.

How to Lower Your Risk?

Screening matters. Most colorectal cancers begin as precancerous polyps, and removing these early saves lives. Current recommended options include:

• Annual or triennial stool-based fecal tests
• Colonoscopy every 10 years
• Virtual colonoscopy every five years
• Sigmoidoscopy every five years

Promising new research shows that mailing stool test kits directly to eligible adults dramatically increases completed screenings—even more than simply offering choice. Yet, screening is still underused: more than 1 in 3 adults aged 45 and older report not getting screened as recommended. To reduce personal risk:

• Maintain healthy body weight and regular physical activity
• Cut back on red and processed meats, refined sugars, and ultraprocessed foods
• Boost fiber intake through plant-based nutrition
• Avoid tobacco and limit alcohol
• Stay alert to symptoms and seek screening or evaluation promptly when indicated

If you’re under 50—or even nearing that threshold—understand this: colorectal cancer is no longer just a disease of older adults. While earlier screening through age-lowering guidelines has helped catch many early-stage cancers in 45–49-year-olds, it doesn’t address the underlying, persistent rise in true early-onset cancer.

The surge among younger adults signals something deeper—and possibly preventable—but only if we tackle it strategically. That means screening more women and men at the right age, investing in research, and making early testing easier and more equitable.

As expert researchers remind us, we’re not merely diagnosing more cancers—we’re getting better at catching them earlier. But to save more lives, identify root causes, and reverse these trends, we must remain proactive. Not just for our generation—but for all who follow.
