It was a typical morning. My mother was getting ready; this was her usual routine: bustling around the house. When she suddenly stopped and shouted, blood was oozing from her nose. As kids, my siblings and I were terrified. We scrambled to help, but it wasn't until later that we learned the cause of that alarming moment: high blood pressure. That day was our first lesson in the silent yet powerful effects of hypertension. Nosebleeds, or epistaxis, are common, and nearly everyone experiences at least one in their lifetime.

While most are minor and often caused by dry air or irritation, some can signal underlying health concerns. One recurring question is whether high blood pressure causes nosebleeds or is merely coincidental.

Where Exactly Does a Nosebleed Occur?

The nose is covered by a rich plexus of small blood vessels, making it prone to bleeding. Most nosebleeds are anterior in origin, occurring at the front of the nose, and are relatively benign. They often occur because of irritants such as dry air, frequent nose-blowing, or trauma.

On the other hand, posterior nosebleeds are caused by a source that is located deeper within the nasal cavity. They are less common but more severe, as the blood tends to flow backward into the throat, making them more difficult to control. Common causes of posterior nosebleeds include trauma, medical conditions, or high blood pressure.

Connection Between Nosebleeds and High Blood Pressure

Hypertension is the condition whereby the pressure of blood against the arterial walls is consistently too high. Over time, this may damage the fine blood vessels in the nose, causing them to rupture more easily.

Significant studies have shown a strong relationship between hypertension and severe cases of nosebleeds necessitating urgent care. A certain study showed that patients diagnosed with high blood pressure had 2.7-fold increased chances of having nosebleeds that were not slight.

However, it should be noted that mild hypertension by itself does not cause nosebleeds. Nosebleeds are more likely to happen during a hypertensive crisis when the blood pressure suddenly rises to above 180/120. A hypertensive crisis can also have other symptoms such as a severe headache, shortness of breath, and anxiety. Therefore, it is considered a medical emergency.

Why Does Hypertension Increase the Risk?

Chronic hypertension makes the walls of blood vessels weaker and less elastic, which easily causes them to tear. In the nose, this is especially vulnerable because the blood vessels are close to the surface. Sudden surges in blood pressure, such as in a hypertensive crisis, can cause tears in these weakened vessels, resulting in nosebleeds.

While hypertension is a contributing cause, nosebleeds occur infrequently as the only manifestation of high blood pressure. This makes regular monitoring for blood pressure all the more crucial, as hypertension has the reputation of being the "silent killer" since people often do not present symptoms until the disease has run its course.

Other Causes of Nosebleeds

  • Dry Air: Cold weather or house heating dries out membranes that line the nose, hence susceptible to cracking.
  • Trauma: Blows in the nose, nose picking or excessive nose blowing can traumatize blood vessels.
  • Intrinsic Disease: Liver disease and kidney disease and drug therapy that affect clotting such as blood thinners enhance the risk of nose bleeding.
  • Foreign Bodies: Children especially tend to insert objects up their noses, which can be irritating and bleed.
  • Allergies or Infections: Chronic nasal inflammation resulting from allergies or colds causes irritation to the nasal mucosa.

Managing Nosebleeds at Home

For most nosebleeds, you can manage them yourself at home:

1. Sit up and lean slightly forward to prevent swallowing blood.

2. Press your nostrils together for at least 10 minutes.

3. Use a cold compress on the bridge of your nose to constrict blood vessels.

4. If the bleeding continues, use a nasal decongestant spray.

Consult a doctor if the bleeding persists beyond 20 minutes, is heavy, or follows a head injury.

Preventing Nosebleeds

Preventive measures can decrease the incidence of nosebleeds:

  • Use a humidifier to maintain moisture in the air.
  • Apply saline sprays or gels to keep nasal passages hydrated.
  • Avoid nasal trauma by being gentle when blowing your nose.

For patients with hypertension, managing blood pressure is the best way to minimize the risk of complications. A combination of lifestyle changes, such as maintaining a healthy diet, regular exercise, and prescribed medications, can help keep blood pressure in check.

When to Worry About Nosebleeds

Most nosebleeds are harmless, but they can sometimes be signs of an underlying health condition. In adults with high blood pressure, frequent or severe nosebleeds should never be ignored. A health provider should be consulted in order to rule out any serious conditions and ensure appropriate treatment.

Regular check-ups, a healthy lifestyle, and awareness about the relationship between nosebleeds and high blood pressure would go a long way to protect your health. Indeed, prevention is always better than cure.

World Population Day: How America's Falling Birth Rate Is Redefining Women's Healthcare?

Updated Jul 12, 2026 | 09:06 AM IST

SummaryOn World Population Day, we look behind the rapidly changing women's healthcare landscape in the United States, driven by a lower birth rate.
World Population Day: Why America's Falling Birth Rate Is Redefining Women's Healthcare?

America's falling birth rate is often reported with concerns like shortage of labour, a growing aging population, and slower population growth. But another major consequence is unfolding within the healthcare system that is going unnoticed.

As fewer women have children and more delay pregnancy, women's healthcare is evolving beyond maternity care to address changing health needs.

The U.S. Birth Rate Is Declining

According to the latest data from the U.S. Centers for Disease Control and Prevention (CDC), 3.63 million babies were born in the United States in 2024, a slight increase from 2023.

However, the general fertility rate fell to a record-low 53.8 births per 1,000 women aged 15 to 44, marking the lowest level ever recorded.

Women’s Healthcare Is Evolving In The US

One of the biggest changes is maternity care. With fewer births being reported, hospitals, particularly in rural communities, are struggling to keep labour and delivery departments financially viable.

The problem has contributed to the rise of a maternity care challenge where pregnant women have limited or no access to obstetric services.

The 2024 March of Dimes Maternity Care Deserts Report found that more than one in three U.S. counties lack a single obstetric clinician or birthing facility, leaving millions of women with reduced access to prenatal and delivery care.

Women living in these areas are more likely to receive inadequate prenatal care and experience higher rates of preterm birth.

Healthcare Focus Beyond Pregnancy

At the same time, healthcare providers are broadening their focus beyond pregnancy. Women today are delaying childbirth, having fewer children, or choosing not to become parents altogether.

As life expectancy increases, demand is growing for services related to menopause, cardiovascular disease, osteoporosis, pelvic floor disorders, mental health, and healthy aging.

The shift also explains why fertility care is expanding despite declining birth rates. As more Americans postpone parenthood into their late 30s and 40s, many require fertility evaluations, egg freezing, or in vitro fertilization (IVF).

Rather than indicating more births, the growing use of assisted reproductive technology reflects changing reproductive timelines.

Management Of Chronic Lifestyle Disorders

An aging female population is also changing healthcare priorities. Older women face a higher risk of chronic diseases such as heart disease, diabetes, osteoporosis, and dementia, increasing the need for preventive care and long-term disease management.

Health systems are investing more in menopause clinics, wellness programs, and other women's health services.

America's falling birth rate is therefore reshaping far more than population statistics. It is redefining women's healthcare, shifting the focus from pregnancy-related care to comprehensive support throughout every stage of life.

On World Population Day, the conversation is not just about how many babies are being born. It is also about ensuring that healthcare evolves to meet the changing needs of women, whether or not they choose to become mothers.

Allergic Rhinitis Affects 1 In 10 Indian Adults. Here's Why Monsoon Makes It Worse, And What Helps

Updated Jul 11, 2026 | 11:00 PM IST

SummaryNearly a quarter of Indian teenagers and one in 10 adults live with allergic rhinitis, and most have never been diagnosed. Monsoon humidity makes it significantly worse. Here's why, and what actually helps.

Chai and pakoras are practically non-negotiable once the rains set in. For a large number of Indians, though, monsoon comes with something less welcome: a blocked nose, itchy eyes, and a "cold" that just won't quit.

Most people write this off as a seasonal cold. It's often not. A large share of the patients I see in July aren't fighting a fresh infection. They're dealing with allergic rhinitis that's been present for months at a manageable level, and monsoon has simply pushed it past a threshold they can no longer ignore.

A Bigger Problem Than It Looks

The scale of this is easy to underestimate. A national study under the Global Asthma Network, which surveyed more than 1.27 lakh children, adolescents, and adults across India, found that close to a quarter of Indian adolescents aged 13 to 14 live with allergic rhinitis. Roughly one in ten adults does too.

Other Indian research puts the overall incidence of allergic rhinitis anywhere between 20 and 30 percent of the population. This isn't a niche complaint. It's one of the more common chronic conditions walking through general practice doors, most of which are simply unnamed.

Mostly Undiagnosed, Rarely Treated Right

The same national study found something more concerning: nearly three out of four people who met the clinical criteria for allergic rhinitis had never actually been diagnosed with it. Many had lived with recurring congestion, sneezing, and disturbed sleep for years without anyone connecting the dots.

A separate survey of over 1,600 physicians across India found that while a large share see allergic rhinitis routinely in practice, more than half had never used immunotherapy, one of the few treatments that changes the course of the disease rather than just quieting it temporarily.

Why Monsoon Makes It Worse

Indian allergen-testing data show a clear rotation of triggers through the year: dust mites dominate winter, pollens dominate summer, and fungal and insect allergens rise sharply once the rains set in.

The reason is straightforward. Once relative humidity in a city climbs past 70 percent, which happens routinely through the monsoon, fungal spores and dust mites both multiply fast. Waterlogging pushes fungal spore counts up further. A damp curtain or a mattress that never quite dries between showers becomes a long-term allergen source that outlasts any single rainy day.

It Rarely Comes Alone

Allergic skin and eye conditions tend to flare with the same seasonal humidity and allergen load as allergic rhinitis, and in practice, they rarely show up in isolation. A patient with monsoon-triggered nasal symptoms is worth a closer look for coexisting asthma, eczema, or conjunctivitis, simply because in the Indian patient population, these conditions travel together more often than not.

What Actually Helps

For anyone with a known allergic condition, a few habits make a real difference once the rains arrive:

  • Start early. Begin or review your antihistamine or inhaled treatment before the monsoon sets in, not after symptoms flare. Allergic inflammation is far easier to control early than to bring down once it's escalated.
  • Keep the fabric genuinely dry. Bedding, curtains, and upholstery that stay even slightly damp become breeding grounds for the mold and dust mites driving most flares. Check for indoor allergens rather than just blaming obvious outdoor ones.
  • Ventilate or dehumidify. Especially in bedrooms, where hours of overnight exposure do the most damage.
  • Keep rescue medication accessible through the season, not just on bad days.
  • Don't wait out a flare that lasts beyond a week. That's usually the point where a proper allergy workup is overdue.
  • If it happens every single monsoon, that pattern itself is a diagnosis worth acting on, not just enduring.

Monsoon doesn't create new allergy patients. It reveals how well the existing ones are actually being looked after.

Study Decodes Why COVID Survivors Continue To Suffer Vision Problems

Updated Jul 10, 2026 | 11:00 PM IST

SummaryThe findings indicate that COVID-19 may trigger a severe immune reaction in the eyes, resulting in chronic inflammation and nerve dysfunction that leads to debilitating vision issues months or even years after infection.

Even a mild case of COVID-19 may trigger long-lasting eye problems, with new research revealing that persistent inflammation and nerve damage could be responsible for symptoms that standard eye tests often fail to detect.

The study, led by researchers at Linköping University in Sweden and published in Nature Communications, sheds light on why some COVID-19 survivors continue to experience debilitating vision issues months or even years after infection.

The research began after people who had recovered from mild COVID-19 sought medical help for persistent eye complaints. Many reported:

  • Severe eye pain
  • Light sensitivity (photophobia)
  • Difficulty reading and focusing
  • Extreme eye fatigue
Despite these symptoms, routine eye examinations often appeared normal, leaving patients without a diagnosis or explanation.

Many participants said the condition significantly disrupted their daily lives, preventing them from working or continuing their education.

What the Study Found

Researchers evaluated 100 people who developed eye problems after mild COVID-19 but had never been hospitalized. Their symptoms had persisted anywhere from three months to three years.

The findings were compared with those of 32 people who had recovered from mild COVID-19 without developing eye symptoms.

Using advanced imaging and laboratory techniques, researchers identified several abnormalities that conventional eye exams failed to detect.

Persistent Inflammation and Nerve Damage

The study found evidence of:

  • Long-term inflammation in the eyes
  • Damage to nerves controlling multiple eye functions
  • Abnormal immune activity involving T cells
  • Changes in proteins found in tear fluid
Researchers noted that the tear protein patterns closely resembled those previously observed in patients with severe and fatal COVID-19, suggesting a prolonged inflammatory response.

Lead author Petros Moustardas, senior research associate at Linköping University, said the findings indicate that COVID-19 may trigger a severe immune reaction in the eyes, resulting in chronic inflammation and nerve dysfunction.

Why Light Sensitivity Happens

One of the most common complaints among participants was extreme sensitivity to light. Researchers found that their pupils were allowing too much light into the eyes because of impaired nerve control.

This abnormal pupil function was also associated with:

  • Headaches
  • Difficulty reading
  • Trouble maintaining focus

An Unusual Eye Movement Disorder

The study also identified impaired coordination between the two eyes.

Some participants developed adult-onset strabismus—commonly known as crossed eyes—a condition that is rare in adults.

Researchers believe this occurred because COVID-19 affected the nerves responsible for controlling eye muscles.

A New Way to Diagnose COVID-Related Eye Problems

Because routine eye tests often miss these abnormalities, the research team developed two diagnostic models.

The first relies on specialized ophthalmic tests available at advanced eye clinics, while the second combines these examinations with tear fluid protein analysis to improve diagnostic accuracy.

Researchers hope these models will help doctors recognize COVID-related eye syndrome earlier and pave the way for future treatments.

"We found that the problems experienced by those affected were not detectable by standard tests. We had to perform specialised examinations to detect deviations. The puzzle pieces then fell into place, and we found explanations for the symptoms," said Neil Lagali, professor of experimental ophthalmology at Linköping University.

He added that while the findings provide important clues about how COVID-19 affects the eyes, more research is needed to develop effective treatments for those living with persistent vision problems.
