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.

Ramadan Fasting: Avoid Excess Salt And Caffeine To Boost Kidney, Prostate Health, Say Experts

Updated Feb 20, 2026 | 05:00 PM IST

SummaryThe prolonged fasting period, without water during Ramadan, can lead to dehydration, raising the risk of kidney stones and UTIs. Avoiding caffeine and salt during Iftar and Sehri, as well as adequate hydration with water-rich foods, can keep the kidneys and prostate in good health.

Dehydration is a serious concern for people fasting during the month-long Ramadan period, and can severely impact kidney and prostate health. Experts suggested that avoiding excess salt and caffeine can help.

While Ramadan fasting is generally safe for people with early-stage chronic kidney disease (CKD), maintaining adequate hydration between iftar and sehri -- the two important meals each day for faithful observing the fasting -- is of significant importance.

Dehydration can lead to acute kidney injury and electrolyte imbalances for individuals with advanced CKD. As prolonged fasting hours -- more than 12 hours a day -- urine becomes concentrated, increasing the risk for kidney stones and Urinary Tract infections (UTIs).

For men with prostate problems, fasting during Ramadan can pose challenges, such as Benign Prostatic Hyperplasia (BPH) or an enlarged prostate, primarily due to dehydration.

“As a practicing urologist and kidney transplant surgeon in India, I often notice a rise in kidney stone pain and urinary infections during Ramzan. When patients fast for long hours -- especially in our warm climate -- urine becomes highly concentrated. That increases the risk of stones and UTIs. Men with prostate enlargement sometimes report worsening urinary flow because they consciously reduce fluid intake,” Dr. Pankaj Panwar, Additional Director, Urology, Fortis Escorts Okhla, New Delhi, told HealthandMe.

The doctor advised people “to hydrate strategically between Iftar and Sehri, avoid excess salt and caffeine”.

How Excess Salt And Caffeine Impact Ramadan Fasting

Consuming high-sodium foods such as processed meats, pickles, salty snacks, and fast food during iftar or sehri can increase thirst and dehydration.

High salt intake forces the body to pull water from cells to dilute the sodium, leading to severe thirst. It can also lead to bloating.

Similarly, caffeine in coffee, tea, chocolate, and energy drinks can be diuretic and cause the body to lose fluids and salts through increased urination. Particularly, drinking coffee or tea at sehri -- the pre-dawn meal -- can lead to faster dehydration during the day.

Caffeine consumption, especially late in the evening, can also interfere with sleep, making it harder to wake up for sehri.

“Ramzan is a sacred month of fasting, but prolonged abstinence from water, especially in hot climates, can increase dehydration risk. Concentrated urine puts stress on the kidneys and may worsen kidney stones or trigger urinary tract infections,” Dr. Mangesh Patil, Urologist at Saifee Hospital, Mumbai, told HealthandMe.

Dehydration during Ramadan fasting can lead to symptoms like headaches, extreme thirst, fatigue, and dizziness. But in case of severe dizziness, fever, confusion, or blurred vision, the experts warned of immediate medical help.

“Do not ignore warning signs like flank pain, fever, or difficulty passing urine. A little planning can prevent an emergency hospital visit,” Panwar said.

Patil said warning signs include severe flank pain, burning urination, fever, vomiting, blood in urine, or reduced urine output. Men with Benign Prostatic Hyperplasia may notice worsening urinary symptoms.

Tips To Prevent Complications

  • Drink 2-3 liters of water between iftar and sehri
  • Include water-rich fruits
  • Avoid excess salt and caffeine
  • Individuals with kidney disease, stones, UTIs, or prostate issues should consult their doctor before fasting.

The Common Colon Cancer Sign You Need To Look Out For

Updated Feb 20, 2026 | 08:00 PM IST

SummaryColon cancer develops from polyps in the colon or rectum, often taking years to show symptoms. Rectal bleeding is the key warning sign and early detection improves chances of survival, though India faces rising incidence and late diagnoses.

Colon (colorectal) cancer begins when small growths called polyps form on the inner lining of the colon or rectum. Over time, changes in the DNA of these cells can cause the polyps to become cancerous.

As abnormal cells multiply, they replace healthy cells and eventually form a mass known as a tumor. This process develops slowly, often taking up to ten years for a precancerous polyp to turn into cancer and begin showing symptoms.

Colon cancer poses serious health risks because cancerous cells can invade healthy tissues. Over time, they may break away and spread to other parts of the body, making detection more difficult since the symptoms can resemble other conditions.

What Is the First Sign of Colon Cancer You Shouldn’t Ignore?

Colon cancer can be difficult to detect because it often develops without obvious symptoms. However, doctors emphasize that the number one warning sign is rectal bleeding or blood in your stool.

"Colon cancer can be hard to diagnose because it can develop asymptomatically,” said Dr. John Nathanson, a gastroenterologist at New York-Presbyterian Allen Hospital.

Dr. Pratima Dibba adds that this symptom should not be misdiagnosed as hemorrhoids, infection, or constipation, since early signs of colon cancer can look similar.

She urges patients to get checked promptly to rule out serious conditions.

Research from the Cleveland Clinic also shows that blood in stool can originate anywhere in the gastrointestinal tract, including the colon.

Detecting colon cancer early is critical, as survival rates can be as high as 90 percent when caught in its initial stages.

What Are Other Symptoms Of Colon Cancer?

Persistent changes in bowel habits (diarrhea, constipation, or narrowing of stool). Other signs include:

  • Abdominal (belly) pain
  • Bloated stomach
  • Constipation or diarrhea
  • Feeling like there’s still poop in your bowel even after you go to the bathroom
  • Feeling tired or weak
  • Unexplained weight loss

Present Day Scenario In India

Colorectal cancer (CRC) is a major health concern worldwide. In India, it is the fourth most common cancer among both men and women. In 2022, there were 64,863 new cases and 38,367 deaths.

Projections suggest that incidence will continue to rise by 2026, reflecting both lifestyle changes and improved detection.

Compared to developed countries, survival rates in India remain lower, largely due to late-stage diagnosis and limited access to screening programs.

The American Cancer Society notes that colorectal cancer is a cancer that starts in the colon or the rectum. Colorectal cancer impacts around 1.9 million people every year, noted the World Health Organization (WHO) as per its 2022 data.

Some of the risk factors include risk factors involve being over the age 50, family history, certain genetic syndromes (like Lynch syndrome), inflammatory bowel diseases, and lifestyle factors (diet high in red meat, alcohol, smoking, inactivity).

The most effective way to prevent colorectal cancer is through annual colonoscopies, screening and stool tests.

Chinese Scientists Could Reverse Type 2 Diabetes Through Stem Cell Therapy

Updated Feb 20, 2026 | 11:00 PM IST

SummaryChinese scientists report the first reversal of type-2 diabetes using stem-cell therapy that rebuilt insulin-producing cells. Though promising, it’s a single case requiring larger trials. The finding matters greatly for India’s rapidly growing diabetes population.

For the longest we have been told that Type-2 diabetes though can be maintained, cannot be fully reversed. However, Chinese scientists may have found a cure, thanks to stem cell therapy. Chinese scientists have achieved the first case in the world in reversal of type-2 diabetes.

What Is Type 2 Diabetes?

Diabetes is a condition characterized by high blood sugar (glucose) levels. It develops when the pancreas either doesn't produce enough insulin, doesn't produce any insulin at all, or when the body doesn't respond properly to insulin, a condition known as insulin resistance.

Type 2 diabetes is the most common form of diabetes and occurs when your body doesn't use insulin properly. The risk of developing Type 2 diabetes increases if you are overweight or obese, or if you have a family history of the condition.

What Did The Study Find?

First, researchers collected stem cells, either from the patient’s own body or from a donor. These cells are valuable because they can develop into many different specialised cell types and take over specific biological functions.

In the laboratory, scientists exposed the stem cells to carefully designed chemical signals and genetic instructions. This guided them to become pancreatic islet cells, more precisely, beta cells, the body’s natural insulin-producing cells.

Once reprogrammed, the cells were grown into small clusters that resemble real pancreatic tissue damaged in diabetes. These clusters are capable of sensing blood sugar levels and releasing insulin when required.

Next came transplantation. The insulin-producing clusters were implanted into the patient’s body, in this case, the abdomen. After implantation, they connected to the bloodstream and began functioning within the body.

After transplantation, the new cells begin behaving like healthy pancreatic beta cells. They sense rising blood glucose levels and release insulin in response, helping bring sugar levels down naturally and reducing, or sometimes removing, the need for insulin injections.

Doctors then closely monitor the patient over time to make sure the cells survive, continue producing insulin, and do not trigger immune rejection or other complications.

This approach falls under regenerative medicine, where the goal is not just to manage type-2 diabetes but to repair the underlying problem by rebuilding the body’s insulin-producing ability.

The early outcome is encouraging, but caution is essential. The success comes from a single case, and that alone cannot prove the treatment works broadly. Larger clinical trials across diverse patient groups are necessary to confirm both safety and effectiveness before it can be considered a reliable therapy.

Why Does This Study Matters Especially For India?

Many experts have recognized India as the diabetes capital, with type-2 diabetes being the most common cost. Globally, diabetes affects about 90 million adults between the ages 20 to 70 years, with over 90 per cent of these cases are of type-2 diabetes. India had 89.8 million adults between ages 20 to 79 years living with diabetes in 2024 and the numbers are expected to increase to 100 million by the end of 2026. This is why this stem cell therapy could prove to be of great help in controlling the numbers, especially for insulin-dependent patients.
