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.

Where You Get Your Rabies Shot Matters: Doctor Explains Why Rabies Vaccines Should Not Be Given In Buttocks

Updated Feb 23, 2026 | 03:50 PM IST

SummaryDoctor warns rabies vaccines must be given in shoulder or thigh, not buttocks, due to poor absorption. Any animal bite or scratch needs prompt washing and vaccination, ideally within 24 hours, though treatment remains useful later.

Dr Srivanjani Santosh, Pediatrician, Social Activist and First Aid trainer, who had earlier spearheaded the ORS campaigned for eight years, urging FSSAI to ban the misuse of the term 'ORS' on non-WHO=standard sugar drinks, has once again shared an important health video on rabies vaccination. Dr Santosh shared that if any mammal, including dog, cat, horse, cow, buffalo, monkey or bat scratch or bit a person, they must be vaccinated with rabies shot.

She also pointed out something many miss: the location of administering the rabies shot. In her video she urged people to not get the shot administered in buttocks, and to only get it on their shoulders or thighs. She also claimed that many clinics and hospitals, despite knowing this fact, are administering rabies vaccination on buttocks.

Why Does Location Of Administration Matter In Rabies Shot?

The World Health Organization (WHO) strongly recommends that rabies vaccines must be injected into the deltoid region, which is the upper arm or near the shoulder region in adults.

In small children, the WHO notes that deltoid region, as well as anterolateral area of the thigh muscle, which is also the upper thigh works.

WHO notes that like any other injections, rabies vaccine should not be given in the gluteal region, that is the buttocks, because of low absorption due to the presence of adipose or the fat tissue.

This video comes at the time when a case of a Birmingham woman losing all her limbs to dog's lick has made headlines all over the news. Health and Me also reported on the same.

Health and Me spoke to Dr. Rakesh Pandit, Senior Consultant & HOD, Internal Medicine at Aakash Healthcare, who further explained, that as per guidelines by the WHO, the rabies vaccine should not be given in the buttocks as they have a heavy layer of fat. The body might not properly absorb the vaccine if it is injected into this fat instead of the muscle, which could result in a vaccine failure.

"A vaccine failure in case of rabies is like a death sentence because the disease is one hundred percent lethal once it shows the signs. The injection site for the vaccine depends on the patient's age; older children and adults must receive the vaccine in the upper arm or shoulder, while infants and toddlers must receive it in the thigh. The vaccine must also be administered with the right needle length to reach the required depth," he said.

Dr Pandit further elaborated, "The place of administering the vaccine (arm or thigh, subcutaneous or intramuscular) has an effect on the immune response, speed at which the vaccine is absorbed, pain and the risk of side effects." He said, "Some vaccines give best results when given in muscle for better immunity. Other vaccines may need subcutaneous administration. When given at the correct site, the vaccines ensure maximum effect, safety and reduced local reactions like swelling."

What Should One Keep In Mind While Getting A Rabies Shot?

Dr Mule points out that even when there are minor scratches, without bleeding, you must get a rabies shot. "Rabies can be contracted through broken skin. Such exposures still require medical evaluation and, in most cases, rabies vaccination."

What Should One Do Immediately After Being Bitten Or Scratched?

  • Wash the wound immediately for at least 15 minutes with soap and running water
  • Apply an antiseptic such as povidone-iodine
  • Do not apply home remedies like turmeric, chili or oil
  • Seek medical care promptly for rabies vaccination and possible immunoglobin

Dr Mule points out that the rabies vaccine should be started as soon as possible. "Ideally within 24 hours of a bite or scratch. However, even if there is a delay of days or weeks, vaccination should still be started immediately as rabies has a variable incubation period," he says.

The temperature of the vaccine matters. "Rabies vaccines are temperature-sensitive and must be stored between 2°C and 8°C. Exposure to heat or freezing can reduce vaccine potency. Poor cold-chain maintenance is a known reason for vaccine failure in rare cases," points out the doctor.

Dr Mule points out that the vaccine should be given intramuscularly in the deltoid or upper arms for adults, as gluteal or buttock injections could lead to inadequate absorption and reduce effectiveness.

Study Links Throat Infection To Sudden Skin Inflammation, Psoriasis

Updated Feb 23, 2026 | 11:01 AM IST

SummaryCommon immune cells, neutrophils, are first responders to a strep throat infection, but also play a key role in the sudden onset of skin inflammation and Guttate psoriasis. The finding may be important when designing future treatments.

A simple strep throat infection, can trigger sudden skin inflammation, leading to psoriasis, particularly in children and young adults, according to a study.

Researchers from the Karolinska Institutet in Sweden showed that a strep throat infection caused by the Group A Streptococcus (GAS) bacterium, can trigger guttate psoriasis by altering the behavior of key immune cells. Guttate psoriasis is an often sudden-onset form of psoriasis with small, red, "drop-shaped" scaling spots on arms and legs.

While neutrophils -- the most common type of immune cell -- are the first immune cells to respond to GAS infection, the study showed that during a streptococcal infection, the immune cells behavior changes depending on their environment.

Notably, among people with guttate psoriasis, the neutrophils presented with antigens -- fragments of pathogens that signal and guide other immune cells -- get accumulated. Once accumulated, the immune cells activated the T cells, leading to inflammation, explained the researchers in the paper, published in the journal eBioMedicine.

"Doctors have long known that strep throat can precede guttate psoriasis, but the biological explanation has been unclear," said Avinash Padhi, first author of the study and Research Specialist at the Division of Dermatology and Venereology, at Karolinska.

"Our findings suggest a link between infection and skin inflammation through the accumulation of antigen-presenting neutrophils in patients' skin," Padhi added.

How Cells Shape Immune Response

The team analyzed receptor–ligand interactions -- the molecular signals cells use to coordinate immune responses to examine how neutrophils interact with other cells.

Magdalini Lourda, senior author of the study and senior research specialist at the Department of Laboratory Medicine, noted that the "results challenge the traditional view of neutrophils as simple first-line defenders".

The findings show that the neutrophils play "a wider role in shaping immune responses, which may be important when designing future treatments."

How Was The Study conducted?

Using single-cell technologies, the team analyzed blood and skin samples of patients with guttate psoriasis. This enabled the researchers to examine thousands of individual immune cells in detail.

To find how neutrophils work in psoriasis, the blood neutrophils from psoriasis patients were compared with those from healthy individuals. Blood neutrophils from patients with severe strep-related lung inflammation were also compared.

What Is Guttate Psoriasis?

Guttate psoriasis is a distinct form of acute-onset psoriasis. It is an inflammatory skin disease characterized by the sudden appearance of red, scaly, and smaller skin lesions widespread over the body.

The condition typically follows an infection, most commonly tonsillitis caused by Group A Streptococcus (GAS). Adolescents and young adults are the most affected. It accounts for about 2 per cent of all cases of psoriasis.

Genetics, environmental triggers, such as an upper respiratory tract infection, and the onset of an inflammatory condition in a distant organ are the major risk factors.

The condition may be diagnosed by skin biopsy, throat swab culture, and blood tests.

Hangover star Ken Jeong's wife Tran Ho Jeong in 2007 discovered a hard lump in her breast while she was breastfeeding their newborn twins Alexa and Zooey. She was diagnosed with stage 3 triple negative breast cancer (TNBC) in 2008.

What Is Stage 3 Triple Negative Breast Cancer?

As per the American Cancer Society, it is an advanced aggressive, and fast-growing cancer that has spread to nearby lymph nodes or tissue, however, does not distant organs. It is characterized by the absence of estrogen, progesterone and HER2 receptors, which requires a combined approach of chemotherapy, surgery, and sometimes also radiations As per the American Cancer Society, TNBC accounts for about 10 to 15 per cent of all breast cancers.

At stage 3, TNBC has grown extensively and invaded nearby tissues and is likely to spread to lymph nodes. However, it has not metastasized to distant organs.

As doctors said, for Tran, it was a "year of hell". She underwent 16 rounds of chemotherapy when Ken was filming The Hangover. This was then followed by a mastectomy and radiation therapy.

"I am going to survive this. I am going to fight. I have to live for the girls and for Ken," she said. After two years of battle, Tran was finally declared cancer free in 2010. Ken called it "the greatest moment" of his life.

What Happens In Breast Cancer?

As per the World Health Organization (WHO), breast cancer is the most common cancer globally with around 2.3 million new cases every year. At the rate of 1 in every 8 person in both sexes and a quarter of all cancer in women with 70% mortality occurs due to constrained resources.

It is a disease where abnormal breast cells grow out of control and form tumors. If it is left unchecked, the tumors can spread throughout the body and become fatal.

It originates in the milk ducts or the milk-producing lobules of the breast. The earliest form is not life-threatening and can be detected in the early stages. Cancer cells can spread into nearby breast tissue and create tumors that cause lumps or thickening. These invasive cancers can spread to nearby lymph nodes or other organs and metastasis can be life-threatening and fatal.

Signs And Symptoms Of Breast Cancer

The common signs are:

  • A breast lump or thickening, often without pain
  • Change in size, shape or appearance of breasts
  • Dimpling, redness, pitting or other changes in the skin
  • Change in nipple appearance or the skin surrounding the nipple (areola)
  • Abnormal or bloody fluid from the nipple

Treatment

The treatment depends on the stages and subtypes of the cancer. However, common treatments involve:

  • Surgery to remove breast tumor
  • Radiation therapy to reduce recurrence of breast cancer around the breast tissues
  • Medicals to kill cancer cells and prevent spread
  • Therapies like hormonal and chemotherapy or targeted biological therapy
