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.
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.
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.
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.
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.
Preventive measures can decrease the incidence of nosebleeds:
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.
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.

High blood pressure, or hypertension, is often called a “silent killer” because it may cause no symptoms, but serious damage to multiple organs can occur. Most people associate hypertension only with heart attacks, but its ill effects extend far beyond the heart. Persistent high blood pressure can gradually damage the brain, kidneys, eyes, and blood vessels, reducing both quality and length of life.
The heart pumps blood through blood vessels, which carry blood to every organ. When hypertension is not properly treated, blood pressure remains high for years, and these blood vessels become stiff, narrow, and damaged. This affects blood flow to vital organs that these blood vessels supply and triggers multiple health problems.
One of the most serious consequences is damage to the brain. Hypertension is the leading cause of stroke. A blood vessel in the brain may either get blocked or burst due to excessive pressure, resulting in paralysis, speech difficulty, or even death.
Repeated uncontrolled hypertension can also impair memory and thinking ability over time, increasing the risk of vascular dementia in older age. Many patients are surprised to learn that controlling blood pressure today may help preserve brain function years later.
Hypertension: The Silent Effect On Kidneys
The kidneys are another major target. High blood pressure damages the delicate blood vessels inside the kidneys, gradually reducing their ability to function.
In fact, hypertension is one of the important causes of renal failure leading to dialysis. Unfortunately, kidney damage develops silently and may remain unnoticed until advanced stages. Regular monitoring of blood pressure and kidney function is therefore essential.
The eyes, too, can suffer from uncontrolled hypertension. The tiny blood vessels of the retina may narrow, leak, or bleed, leading to blurred vision or even permanent visual loss.
Eye specialists can often detect signs of long-standing hypertension during routine retinal examination. Sometimes, the eyes provide the first warning that blood pressure has been poorly controlled for years.
High blood pressure also weakens arteries throughout the body. It accelerates hardening of blood vessels, increases the risk of peripheral artery disease, and can contribute to aneurysms — dangerous ballooning of arteries that may rupture unexpectedly. In some patients, hypertension is linked to sexual dysfunction, sleep disturbances, and reduced exercise capacity.
The good news is that hypertension is both detectable and treatable. Lifestyle measures remain the foundation of prevention and control.
Maintaining a healthy body weight, exercising regularly, avoiding tobacco, limiting alcohol, and managing stress can significantly lower blood pressure.
Adequate sleep is equally important. However, many patients also require medicines, and these should be taken regularly even when one feels perfectly well.
Adults should check their blood pressure periodically, especially after the age of 30 or earlier if there is obesity, diabetes, or a family history of hypertension. Early diagnosis and proper treatment can prevent devastating complications later.
Hypertension is not merely a “heart problem.” It is a whole-body disease that silently injures multiple organs. Recognizing this reality is the first step toward prevention, timely treatment, and healthier living.

The risk of hantavirus spreading is generally considered low, as repeatedly stated by the World Health Organization (WHO) and other global health agencies, after the recent outbreak on the MV Hondius cruise ship. However, a shocking peer-reviewed study has found that the Andes strain of the rat-borne virus can persist in human semen for up to six years.
More concerning is the possibility that the virus could potentially be transmitted sexually even after a person has recovered, according to the 2023 study published in the journal Viruses.
The research, conducted by Swiss scientists at Spiez Laboratory, suggests that hantavirus may survive in the male reproductive tract like viruses such as Ebola.
The research team, which included scientists from the University of Bern and the University of Lausanne, investigated a 55-year-old man who had contracted the Andes strain of hantavirus in South America six years earlier.
The researchers discovered that although the virus was no longer detectable in the man’s blood, urine, or respiratory tract, it was still present in his semen 71 months later.
"Viral RNA remained primarily detectable intracellularly in semen samples throughout the complete study period of almost six years," the 2023 study stated,
“Taken together, our results show that the Andes virus has the potential for sexual transmission,” it added. However, so far no confirmed case of such transmission has yet been documented.

Hantavirus is not the first virus found to persist in the male reproductive system. According to the study, viruses such as Ebola and Zika are also known to evade the immune system by remaining hidden in the testes for extended periods.
A 2021 Ebola outbreak in Guinea, which resulted in 23 cases and 12 deaths, was later linked to a survivor of the 2014–2016 West Africa epidemic who reportedly transmitted the virus sexually years after recovery.
The testes are considered a biological “safe harbour” for at least 27 infectious diseases, enabling certain pathogens to remain hidden in the body and potentially spread years after a patient has recovered.
Because sperm cells are essential for reproduction, they are shielded from the body’s immune response. However, this immune protection can also create an environment where viruses are able to survive and persist for long periods.
Analysts at Airfinity, a company that tracks global health risks, recommend that male patients should receive “extensive safe-sex guidance beyond the [42-day] quarantine”, the Telegraph reported
The guidance should be “analogous to the World Health Organization’s (WHO) Ebola survivor semen-monitoring protocols,” it added.
The WHO protocols recommend that the semen of male Ebola survivors should be tested every three months and should not be considered virus-free until two consecutive negative test results are obtained.
Until cleared, they should “abstain from all types of sex” or “use condoms consistently and correctly.”
They should also wash themselves “thoroughly” with soap and water after any contact with semen – including after masturbation, according to the guidance.
According to the World Health Organization (WHO), 11 people have been affected by the rat-borne virus so far, of whom three have died.
A Dutch couple is believed to have been first exposed to the virus while visiting a birdwatching site in Argentina.
The WHO has confirmed that the Andes strain of hantavirus — the only strain known to spread from person to person — is behind the outbreak.
While all passengers onboard the cruise have been taken care of by health authorities, the virus' long incubation period is a serious risk factor. Which means that even those asymptomatic can turn infectious 6-8 weeks later.

While GLP-1 weight-loss drugs such as Wegovy and Mounjaro have helped patients lose weight, a major concern has been weight regain once the therapy is stopped. Now, a new study by US scientists suggests that a daily pill may help prevent that rebound weight gain.
According to a clinical trial led by Weill Cornell Medicine and NewYork-Presbyterian, switching to the once-daily orforglipron pill may not only help maintain weight loss but also preserve cardiometabolic benefits.
Orforglipron is US drugmaker Eli Lilly’s first oral pill for weight loss, marketed as Foundayo. In April, it received approval from the US Food and Drug Administration (FDA).
In the Eli Lilly-funded trial, published in the journal Nature Medicine, researchers found that patients in the Phase 3b clinical trial maintained around 75–80 per cent of their weight loss. They also experienced several additional health benefits, including:
The ATTAIN-MAINTAIN trial enrolled patients who had already achieved substantial weight loss that later plateaued while taking weekly injectable GLP-1 drugs during the SURMOUNT-5 trial.
The study randomized:
The results showed that patients switching from tirzepatide to orforglipron maintained an average of 74.7 per cent of their body weight reduction, compared with 49.2 per cent in the placebo group.
Meanwhile, patients who switched from semaglutide to orforglipron maintained 79.3 per cent of their body weight reduction, compared with 37.6 per cent in the placebo arm.
Over the 52-week trial period, participants treated with orforglipron gained:
Eli Lilly licensed orforglipron, the active ingredient in Foundayo, from a Japanese pharmaceutical company in 2018.
Like injectable GLP-1 drugs, Orforglipron is available in six doses ranging from 0.8 mg to 17.2 mg. Patients typically begin at the lowest dose and gradually increase under medical supervision.

Unlike some oral GLP-1 drugs, people taking orforglipron do not need to restrict food or drink intake after taking the pill. Researchers say the small molecule is absorbed quickly into the bloodstream and reaches target tissues efficiently.
Foundayo is not approved for use in children and carries warnings about potential thyroid tumours, including thyroid cancer.
The drugmaker advises patients to watch for symptoms such as:
