A new long-term study has revealed a troubling health trend in the United States: the number of Americans living with both type 2 diabetes and high blood pressure has doubled over the last two decades, with 1 in 8 adults now affected. Even more concerning is the steep rise in mortality risk associated with this dual diagnosis—suggesting that the combo of these two chronic diseases may be deadlier than previously understood.

Published in the peer-reviewed journal Diabetes Care, the study spans nearly 20 years and highlights how a rapidly increasing population is living with multiple metabolic risk factors—a condition that significantly raises the odds of heart disease, stroke, kidney failure, and early death.

Researchers at Columbia University's Mailman School of Public Health mined health information from close to 49,000 American adults who took part in the National Health and Nutrition Examination Survey from 1999 through 2018. The National Center for Health Statistics conducted the survey, which captures interviews, laboratory tests, and physical exams to measure the health of the country.

According to the study, only 6% of Americans in 1999 suffered from both type 2 diabetes and high blood pressure. By 2018, it had risen to 12%, or about 1 in 8 adults. Those with both conditions were more than twice as likely to die from any cause and three times more likely to die from heart disease than those with neither condition.

"Even having co-existing prediabetes and high blood pressure was linked to up to 19% greater risk of death," said lead researcher Dr. Nour Makarem, assistant professor of epidemiology at Columbia University.

This is important because it indicates that heightened risk begins even before someone officially qualifies by clinical criteria as having diabetes or hypertension.

Why Type 2 Diabetes And High Blood Pressure Compound Health Risks?

Having either condition on its own—type 2 diabetes or high blood pressure—already raises one's risk for severe complications but when they occur together, their interaction in the cardiovascular system is much more destructive.

Approximately two out of three patients with type 2 diabetes have high blood pressure or are prescribed medication for it. Among individuals with both disease states, about 33% died over a median 9-year follow-up period.

For individuals with only one condition, the mortality rate remained at 20–22%, whereas individuals with neither condition suffered from a mere 6% fatality during the same period of time.

The research identified that in comparison with individuals with:

Hypertension alone, developing both conditions increased the risk for all-cause mortality by 66% as well as cardiovascular death by 54%.

Type 2 diabetes alone, but with both conditions, overall risk of death was 25% higher and greater than two-fold increased cardiovascular mortality.

Why Type 2 Diabetes and High Blood Pressure Pair so Deadly?

Both type 2 diabetes and high blood pressure are "silent killers." Alone, they tend to produce no discernible symptoms until complications—such as stroke, heart failure, or kidney damage—arise. Combined, however, they provide a deadly combination of cardiovascular stress.

Diabetes disables the body's ability to keep blood sugar in balance. High glucose levels destroy blood vessels and organs by repeated damage.

Hypertension makes the heart work harder to circulate blood, which hardens and weakens the arteries.

When both conditions occur together, this speeds up the deterioration of the arteries, kidneys, and heart, making heart attack, stroke, and end-stage renal disease requiring dialysis or transplantation more likely.

Early Warning Signs That Are Often Missed

Another significant takeaway of the research is that the danger of death starts even prior to a full-blown diagnosis. Prediabetic and high-blood-pressure persons—even if they are below diagnostic levels—had a 19% greater risk of mortality.

Although type 2 diabetes can quietly develop without apparent symptoms, there are some early warning signs that should never be overlooked—particularly if you're at risk. The sooner you detect diabetes, the less complicated it is to control and prevent long-term complications. Even slight symptoms deserve a chat with your doctor.

• One of the first and most indicative symptoms of high blood sugar is urinating more often, particularly at night. As blood glucose increases, the kidneys work around the clock to flush out the excess glucose. When they're unable to keep pace, glucose leaks into the urine, causing more frequent trips to the bathroom.

• Too much sugar in the urine not only impacts hydration—but also is a breeding ground for bacteria and yeast. This increases the likelihood of infections in the urinary tract and yeast infections, particularly in women. If you find that you have persistent infections that are difficult to clear, you might want to be tested.

• Another visible clue is the appearance of dark, velvety patches of skin, typically found in body folds like the neck, armpits, or groin. These areas may indicate insulin resistance—a common precursor to diabetes.

• If you’re eating regularly but still feel hungry all the time, your cells may not be properly absorbing glucose. As a result, your body stays in a constant state of seeking energy, driving persistent hunger.

• Ironically, even though you are hungrier, you may actually lose weight unexpectedly. Since there's not enough glucose flowing into cells, your body starts to break down muscle and fat for energy.

• This energy shortage also leads to constant fatigue and weakness. You could be tired, even with a good night's rest. Dehydration caused by frequent urination only adds to that pervasive fatigue.

• Another troubling symptom is blurred vision, which can appear and disappear. High blood glucose can harm the tiny blood vessels in the eyes, leading to more severe conditions—blindness, if not treated.

• Most people experience a tingling or numb feeling in their hands or feet. This is caused by nerve damage from years of high blood sugar levels. Refereed to as diabetic neuropathy, this can also result in long-term chronic pain or loss of sensation.

This result highlights the importance of early screening and proactive prevention measures, particularly for individuals in their 30s and 40s who are unaware they're at risk. The research also reignites debate around various forms of diabetes, many of which have different risks:

Type 1 Diabetes: Autoimmune condition in which the pancreas releases no insulin.

Type 2 Diabetes: A metabolic disorder in which the body fails to utilize insulin. Frequently associated with obesity, a diet lacking in nutritious foods, and physical inactivity.

Prediabetes: A silent diabetes precursor with no warning signs.

Gestational Diabetes: Appears during pregnancy and increases risk of type 2 diabetes in the future.

Of these, type 2 diabetes is the most common and can be directly associated with lifestyle modifications that are often possible.

This highlights the pressing need for public health approaches to prevent and manage these diseases and to halt these negative trends," Dr. Makarem stressed.

At present, approximately two-thirds of adults with diabetes have blood pressure above 130/80 mm Hg or are taking antihypertensive therapy.

Since most symptoms are mild or undetectable, screening is necessary on a regular basis. The American Diabetes Association suggests that all adults over the age of 45 should be screened for diabetes. If you are younger but have risk factors that include obesity, being inactive, having a poor diet, or a family history of diabetes, you need to be tested too.

Screening is typically a straightforward blood test. If normal, the ADA recommends repeat testing at three-year intervals to track changes.

As an ageing population, inactive lifestyles and obesity on the rise, the co-epidemic of diabetes and high blood pressure is set to expand unless there are systemic changes.

Nipah virus outbreak in India has triggered screenings across Asian airports. However, the health authorities of the Kolkata hospital where two nurses were admitted confirmed that one of the two nurses has been discharged from hospital. While this may be a good sign, there is still need to be cautious of the virus.

Nipah Virus Outbreak In India: How Does It Work?

Experts and doctors are still telling people to be cautious of what they eat, as the fatality rates are from 40 per cent to as high as 75 per cent. It is a zoonotic infections that infects vital organs like brain and lungs. However, the virus is also able to manipulate body's immune system.

Nipah Virus In India: How Does It Affect Immune System?

Nipah virus is lethal because it can outpace, suppress and misdirect immune responses. Speaking to NDTV, Dr Dip Narayan Mukherjee, Consultant, Microbiology and Infectious Diseases at CK Birla Hospitals said, Nipah virus leaves the body unable to clear the infection in time. "Understanding this immune disruption is critical to explaining why Nipah causes severe encephalitis, multi-organ failure and high mortality, and why early detection and containment remain the most effective tools against it."

This immune disruption begins early in the infection. The body’s first line of defense against viruses is the innate immune system, which relies heavily on interferons. These signalling proteins alert neighboring cells to the threat and trigger antiviral mechanisms that slow viral replication.

“One of the earliest ways Nipah evades immunity is by interfering with the innate immune response,” Dr Mukherjee says. “The virus suppresses interferon activity, allowing it to multiply rapidly before the immune system can respond adequately.”

Research published by the World Health Organization and other virology institutes shows that specific Nipah virus proteins block interferon signalling pathways. This gives the virus a crucial head start, enabling widespread infection before the immune system is fully activated.

Nipah Virus Outbreak In India: Inflammation And Low Immunity

As the infection progresses, Nipah targets the cells lining blood vessels, a feature that sets it apart from many other respiratory viruses. Damage to these vessels allows the virus to spread to multiple organs, including the brain, while also triggering widespread inflammation.

Instead of a controlled antiviral response, the body releases large amounts of inflammatory molecules. This excessive inflammation leads to tissue injury, swelling and organ dysfunction, contributing to respiratory failure, neurological symptoms and circulatory collapse in severe cases.

Another hallmark of Nipah infection is immune exhaustion. Although the virus does not directly infect most immune cells, the intense inflammatory environment causes them to become overactivated and eventually dysfunctional. Once these defense cells lose their ability to control viral replication, the infection accelerates, and supportive care becomes less effective in later stages.

When Nipah crosses into the brain, immune control becomes even more limited. The brain’s immune responses are naturally restrained to prevent damage, allowing the virus to persist. At the same time, inflammation causes swelling, seizures and encephalitis. Neurological complications remain the leading cause of death in Nipah outbreaks.

Nipah Virus Outbreak In India: Why Antibodies Against The Infection Arrive Late

The adaptive immune response, which includes antibody production and virus-specific T-cells, also struggles to keep pace with the rapid spread of Nipah. By the time neutralizing antibodies are produced, significant organ damage may have already occurred, particularly in the brain. This delayed response explains why severe encephalitis is common even in people without underlying health conditions.

Using artificial intelligence (AI) in breast cancer screening can reduce the number of cancers diagnosed in late stages by 12 percent, according to a major new study from Sweden.

The study found that fewer women in the AI group were diagnosed with breast cancer in the years after screening. There were 1.55 cancers per 1,000 women in the AI-supported group, compared with 1.76 per 1,000 in the standard screening group.

According to lead author Dr Kristina Lang of Lund University in Sweden, this indicates better early identification of clinically relevant cancers. She said of the results: “Our findings show that AI-supported screening improves the early detection of breast cancers that are more likely to become aggressive or advanced.

“This results in fewer serious cancers being diagnosed in the interval between screenings.”

She added that wider adoption of AI-supported mammography could ease workforce pressures on radiologists while improving early detection, including of aggressive cancer subtypes.

What Did The Study Find?

The study, published in The Lancet, involved around 100,000 women who took part in routine mammography screening between April 2021 and December 2022, making it the first large randomised trial to assess how AI performs in real-world breast cancer screening.

Women were randomly divided into two groups. One group received standard screening, where mammograms were read by two radiologists and the other group had AI-supported screening, where an AI system assessed the scans first.

Low-risk cases were read by one radiologist, while higher-risk cases were checked by two, with the AI also flagging suspicious areas.

The results showed that 81 percent of cancers in the AI-supported group were detected during screening, compared with 74 percent in the standard screening group—a nine percent increase. Importantly, false-positive rates remained similar, at 1.5 percent in the AI group and 1.4 percent in the control group.

Despite positive results, Dr Lang cautioned that introducing AI into healthcare must be done carefully, using validated tools and continuous monitoring to understand how performance may vary across regions and over time.

Breast Cancer: A Rising Crisis

About 1.9 lakh Indian women are diagnosed with breast cancer annually, meaning that a new case is diagnosed every four minutes. On average, a woman in India dies of breast cancer every eight minutes, highlighting how urgently the country needs stronger awareness, early diagnosis and sustained care.

One factor that sets India apart is the age at which women are affected. Almost half of all breast cancer patients in the country are younger than 45. This is a much higher proportion than seen in many Western nations, where the disease is usually detected later in life.

Moreover, sedentary habits, excessive consumption of processed foods as well as alcohol and smoking promotes obesity and hormonal changes which pave the way for breast cancer development.

During today's Union Budget, Finance Minister Nirmala Sitharaman announced multiple initiatives and a staggering ₹1,62,671 crore to increase agricultural production in the country

Sitharaman, who was presenting her ninth consecutive budget, said the government will support the growth of high-value crops such as coconut, sandalwood, cocoa and cashew in coastal regions, agarwood in the North East and nuts,s including walnuts, almonds and pine nuts.

Dedicated programmes will focus on rejuvenating old orchards, expanding high-density cultivation and promoting value addition by engaging rural youth, while new coconut promotion schemes aimed at boosting productivity will be launched.

She noted: "India is the world’s largest producer of coconuts. About 30 million people, including nearly 10 million farmers, depend on coconuts for their livelihood. To further enhance competitiveness in coconut production, I propose a Coconut Promotion Scheme to increase production and enhance productivity through various interventions 16 including replacing old and non-productive trees with new saplings/plants/varieties in major coconut growing states.”

And health experts across the country say that an increase in consumption of these food items can significantly help improve your health.

Dr Sunil Kutty, Director and Consultant Brain and Spine Surgeon, NewEra Hospitals, Navi Mumbai, exclusively told Healthandme: "The Union Budget emphasises improving national nutrition and food security, recognising that better diets are foundational to health and well‑being.

"By strengthening food systems, supporting high‑value crops and enhancing access to nutrient‑rich foods, the government aims to reduce malnutrition, micronutrient deficiencies and diet‑linked diseases like Type-2 diabetes, obesity, and cardiovascular diseases. Integrating nutrition‑focused initiatives with healthcare can lower the overall burden of non‑communicable conditions and improve immunity, especially among children, women and vulnerable groups.

"These measures also support rural livelihoods, increasing access to affordable, healthy food across socio‑economic groups, contributing to long‑term health outcomes and reduced healthcare costs."

Coconut: Prevents Cell Damage And Packed With Essential Minerals

When eaten in moderation, coconuts offer healthy fats (MCTs), fibre, manganese, copper, iron, potassium as well as ample of antioxidants. Potassium helps balance sodium levels in the body and potentially lowers blood pressure, while the fruit's high fibre content supports bowel health and prevents constipation.

Coconuts are also especially high in manganese, which is essential for bone health and the metabolism of carbohydrates, proteins, and cholesterol. Along with this, they’re also rich in copper and iron, which help form red blood cells, as well as selenium, an important antioxidant that protects your cells and reduces cell damage which can prevent future cancer development.

A 2020 case study found that supplementing with coconut oil helped lower blood sugar levels in a person with diabetes, a condition characterized by unstable blood sugar levels. The researchers suggest that these effects may be due to the coconut’s anti-inflammatory properties and antioxidant content.

A 2024 animal study also found that consuming coconut water after eating could help manage blood sugar levels. This could be due to bioactive compounds like ellagic acid, butin, and quercetin, among others.

Sandalwood: Skin Benefits and Anxiety Reduction

Sandalwood offers benefits for skin health (acne, ageing, brightening), mental well-being, aid sleep, and possesses anti-inflammatory, antiseptic as well as antibacterial properties, making it useful for skin irritations, respiratory issues, and even potentially lowering blood pressure.

A 2017 Sigma study suggests that lavender, sandalwood, and orange-peppermint aromatherapy helped reduce self-reported feelings in anxiety of 87 women undergoing a breast biopsy.

In a 2016 pilot study published in NPC of 32 people in Vienna, Austria, participants inhaled lavender and sandalwood oil. The study found that the participants’ blood pressure levels were lower and that the cortisol levels in their saliva were lower after the aromatherapy.

Cocoa: Boosts Heart Health

While cocoa is most famous for its role in chocolate production, it is also packed with polyphenols and reduces high blood pressure by improving nitric oxide levels.

Researchers have previously linked polyphenols to numerous health benefits, including reduced inflammation, lower blood pressure and better heart health. It also contains flavanols, which have potent antioxidant and anti-inflammatory effects.

The flavanols in cocoa also improve nitric oxide levels in the blood, which can enhance the function of the blood vessels and reduce blood pressure.

Nuts: Improve Overall Health

Over time, this can improve artery health, lower bad LDL cholesterol, and reduced risk of blood clots, with varieties like almonds, walnuts, and pistachios providing unique nutrients like omega-3s, antioxidants and selenium.

Lastly, Pattabhi Rama Rao, Managing Director, Gourmet Popcornica also noted to Healthandme: "These measures, combined with stronger market linkages and local enterprise development, can make wholesome foods more affordable and accessible, directly supporting better nutrition and overall public health outcomes across the country. Not just this, farmers being able to access equitable income will enable them to access high-quality, nutritious food.

"By prioritising high-value and nutritious crops like coconut, cashew, cocoa, and walnuts, the government is not just enhancing farmers’ incomes but also ensuring that healthier, nutrient-rich foods are more widely available to the public.

"Diversifying production through fisheries, livestock, and region-specific crops, like maize in Andhra Pradesh and Chhattisgarh, will improve access to proteins, healthy fats, and essential micronutrients, which are vital for balanced diets.
