You also have certainly experienced what ear disturbances feel like when you leave a really loud concert: temporary and seemingly meaningless. But what if the noise isn't a maddening ringing, and more like steady thumping in synchronization with your heartbeat? This condition is called Pulsatile Tinnitus and is characterized by a rhythmic whooshing, thudding, or pulsing in one or both ears. Though at times frustrating, and even sometimes worrisome, it most often has a known cause, and is in fact, an early indicator of a significant disease process.

Depending on the presence of a vascular abnormality - such as an aneurysm or arteriovenous malformation-surgery or endovascular treatments may be necessary.

Pulsatile tinnitus can be temporary and harmless, but in some cases, it may be a warning sign of a serious condition. If the rhythmic pulsing in your ear persists, seek medical evaluation to rule out any underlying health issues. Identifying the root cause is the first step toward finding relief and protecting your long-term health.

What Is Pulsatile Tinnitus?

Pulsatile tinnitus is a rare form of tinnitus that occurs due to blood flow irregularities in the vessels near the ears. Unlike traditional tinnitus, which is often described as a constant ringing, buzzing, or hissing, pulsatile tinnitus is rhythmic and synchronized with your heartbeat.

Most people experience it in just one ear, but it can occur in both. While it's usually harmless, persistent pulsatile tinnitus should not be ignored as it may signal an underlying cardiovascular or neurological issue that requires medical attention.

Why Do You Hear Your Heartbeat in Your Ear?

Hearing your heartbeat in your ear can be unsettling. While occasional pulsatile tinnitus is generally harmless, frequent or persistent cases warrant a closer look. The sound results from turbulent blood flow in the vessels around the ear, which can be caused by various conditions, including high blood pressure, anemia, or even pregnancy. Some individuals may experience it only when lying down or in specific positions.

Common Symptoms of Pulsatile Tinnitus

While symptoms differ from individual to individual, the most common symptom of pulsatile tinnitus is the presence of a rhythmic sound in one or both ears that occurs in synchronization with the heartbeat. These sounds can be described as follows:

• Whooshing
• Grinding
• Hissing
• Thudding
• Whistling

The intensity of the sound may vary with physical activity, stress, or change in body position.

What Triggers Pulsatile Tinnitus?

1. An Intense Workout

Vigorous exercise increases blood flow and cardiac output, causing temporary pulsatile tinnitus. The extra blood circulating through your arteries near the ears can create a pounding sensation, which usually subsides after you cool down.

2. Anemia

When you have low red blood cell levels, your heart must pump harder to supply oxygen to your body, creating turbulent blood flow near the ear. This increased circulation can lead to pulsatile tinnitus.

3. Thyroid Disorders

Thyroid conditions, particularly hyperthyroidism, can alter blood composition and pressure, leading to fluctuations in venous return to the heart and causing pulsatile tinnitus.

4. Fluid in the Ear or an Ear Infection

When fluid builds up in the middle ear, either due to an infection or other causes, blood vessels around the ear may pulsate the trapped fluid. This can result in hearing a heartbeat-like thumping sound.

5. High Blood Pressure

High blood pressure (hypertension) forces blood to flow more aggressively through your arteries, increasing turbulence and leading to pulsatile tinnitus. If your systolic pressure is 120 or higher and/or your diastolic is above 80, your risk increases.

6. Atherosclerosis

A buildup of plaque in the arteries (atherosclerosis) can narrow blood vessels, reducing blood flow and causing pulsations that may be heard in the ear. This is more common in older adults.

7. Pregnancy

Pregnant individuals experience increased blood volume and pressure, which can affect major blood vessels near the inner ear, causing pulsatile tinnitus. Fluid retention during pregnancy may also amplify pulsations.

8. Other Underlying Conditions

While vascular issues are common causes, other conditions can also trigger pulsatile tinnitus, including:

• Head trauma
• Paget’s disease (a chronic bone disorder)
• Hyperthyroidism (overactive thyroid)

When Should You See a Doctor?

While occasional pulsatile tinnitus isn’t necessarily a cause for alarm, persistent or worsening symptoms should be evaluated by a healthcare professional. It may indicate a serious vascular, neurological, or cardiovascular issue that requires treatment.

Signs You Need Immediate Medical Attention:

• Prolonged tinnitus that lasts for more than a few weeks
• Sudden increase in loudness or pitch
• Associated symptoms such as headache, dizziness, or blurred vision
• Pulsatile tinnitus after head trauma

How Is Pulsatile Tinnitus Diagnosed?

A medical professional—preferably a neurotologist or otolaryngologist (ENT specialist)—can assess pulsatile tinnitus through:

• A physical exam to check for vascular abnormalities
• Hearing tests (audiometry) to evaluate sound perception
• Imaging scans (MRI, CT, or ultrasound) to detect blockages, tumors, or aneurysms
• Blood tests to detect anemia, thyroid disease, or cholesterol level

Treatment of Pulsatile Tinnitus

Treatment depends on the underlying cause. Some of the common methods include:

• Treatment of Hypertension
• Lifestyle modifications like reducing salt intake, managing stress, and exercising regularly can be helpful if hypertension is the causative agent.
• Medications are also given in some cases.

Treatment of Anemia or Thyroid Conditions

• Iron supplements are prescribed for anemia, while thyroid conditions require medication or hormone therapy.
• Treating Ear Infections or Fluid Buildup
• Doctors may prescribe antibiotics, antihistamines, or decongestants to clear fluid accumulation.
• Surgical or Interventional Procedures

Heart disease remains one of the leading causes of death globally, and while technology has evolved to the point where predicting heart attacks is possible, the medical world still struggles to put this into practice. Experts point to both promise and pitfalls in predictive cardiology, revealing why such life-saving tech is not yet a mainstream reality.

The Tech Is Here, But We Are Not Using It Enough

Dr. Vikrant B. Khese, Cardiologist at Jehangir Hospital, Pune, says the idea that we can predict heart attacks before they happen is both “exciting and frustrating, because while the technology exists, its real-world implementation remains limited.”

He explains that artificial intelligence (AI) and machine learning (ML) have incredible potential in this field. These tools can analyse vast datasets, such as blood pressure, lipid profiles, ECGs, imaging, and even genetic markers, to uncover patterns that might be invisible to the human eye. “These tools can detect subtle risk factors that may be missed in routine clinical practice. However, several challenges continue to hold us back,” he says.

One of the biggest concerns is the source of the data feeding these algorithms. “The majority of AI models are trained on Western datasets that do not reflect the unique genetic, environmental, and lifestyle factors of Indian or Asian populations. This creates a mismatch, resulting in lower accuracy and reliability for non-Western patients.”

Dr. Khese adds that cardiovascular disease is deeply multifactorial. It is not just about clinical metrics. “Stress, socioeconomic status, cultural diet patterns, air pollution, and unstructured physical activity all influence risk but are difficult to quantify in a dataset. AI still struggles with these intangible but crucial variables.”

And even when predictive tools are developed, another hurdle lies in the healthcare system’s ability to use them. “Data-driven predictions can only be as good as the data input. In India, inconsistent electronic medical records, underreporting, and fragmented healthcare systems make it harder to gather high-quality longitudinal data, limiting the AI's learning potential.”

Crucially, there is also a behavioural gap. “Even when prediction tools exist, they are not routinely used by clinicians due to scepticism, lack of training, or workflow disruption. Bridging the gap between innovation and implementation is a major hurdle.”

According to Dr. Khese, technology must complement clinical judgement, not replace it. “AI is a powerful tool but not a standalone solution. Until we combine high-quality, representative data with clinical wisdom and system-level integration, the promise of predicting heart attacks before they happen will remain underutilised. The future lies in synergy; technology must empower doctors, not replace them.”

Prediction Tools Exist—But We’re Waiting for Symptoms

Dr. Vijay D'Silva, Medical Director of White Lotus International Hospital and Clinical Advisor and Mentor of Heartnet India, backs this view and draws attention to major international trials. “Research from the University of Oxford has suggested that a global trial of an AI tool that can predict the 10-year risk of heart attack has shown that in about 45 per cent of patients with chest pain, treatment could be improved,” he shares.

“Early detection of cardiac risk allows timely treatment and monitoring that can help reduce the mortality rate,” he says, explaining that most coronary blockages are asymptomatic. “Some present with chest, arm or jaw pain on exertion (angina pectoris). Few present as a heart attack or sudden death. People seek treatment after a heart attack when the damage is already done.”

According to Dr. D’silva, “With the help of the right tools, it is now possible to predict a heart attack before it occurs.” Among these tools are blood tests, ECGs, and advanced risk calculators such as the AHA PREVENT calculator, ASCVD Risk Calculator Plus, QRISK3, and SCORE2.

He points out how the 2023 AHA PREVENT calculator estimates 10-year cardiovascular risk in individuals aged 30 to 79, and 30-year risk in adults aged 30 to 59. “Early-stage detection of CVD minimises the cost and also reduces the CVD mortality rate,” he says.

This tool divides patients into four risk categories, each with its own treatment strategy:

• Low risk (<5%): Maintain healthy lifestyles and reassess every five years.
• Borderline risk (5–7.4%): Lifestyle changes and monitoring of risk-enhancing factors like BP, sugar, weight and lipids. CAC scoring can further stratify risk. Annual reassessment recommended.
• Intermediate risk (7.5–19.9%): Calls for lifestyle management, preventive medication (statins or aspirin), stress testing and CT coronary angiogram. Yearly reassessment is needed.
• High risk (≥20%): Requires intensive lifestyle changes, pharmacotherapy, imaging and close follow-up.

Despite these advances, Dr D'Silva says, “The gap lies in implementation. Most people still wait for the symptoms to appear before seeing a doctor. Heart attacks, unfortunately, strike without any warning, especially in women and younger patients, where symptoms can be atypical.”

He stresses that predictive cardiology is not yet standard in clinical practice. “People who are at risk seek care when symptoms arise. But in cardiology, symptoms often come too late. Up to 50 per cent of heart attack victims had no prior warning signs.”

Why Risk Calculators Are NotFoolproof

• Patients with LDL cholesterol ≥190 mg/dL
• Those with familial hypercholesterolemia
• Patients with type 1 diabetes
• People with other risk-enhancing factors like family history of early cardiovascular disease, metabolic syndrome, chronic kidney disease, chronic inflammatory diseases (psoriasis, RA, lupus), or early menopause

The Way Forward

Dr. D'silva concludes, “The ability to predict heart attacks is advancing continuously, but we need public awareness and equitable access to make predictive cardiology more standard.”

In short, we can predict heart att but until we normalise risk screening, improve data systems, and bridge the clinical gap, too many heart attacks will continue to catch people and systems off guard.

When strands clog your shower drain or your brush looks full every time you run it through your hair, panic is a natural response. Hair loss, or alopecia, is not just a cosmetic concern; it often hints at something deeper. And yet, thanks to internet half-truths and old wives’ tales, myths about alopecia spread faster than a viral meme. On World Alopecia Day, we turn to experts to separate fact from fiction while spotlighting the hidden medical conditions that might be behind the hair fall.

It is Not Just "Shedding Season": Medical Reasons Behind Hair Loss

Autoimmune Disorders (Alopecia Areata):

Hormonal Imbalances (Thyroid Disorders and PCOS):

Nutritional Deficiencies:

The good news? “Early diagnosis and treatment of these conditions can help restore hair growth and prevent permanent damage,” he assures.

Wigging Out Over Myths

Myth 1: “Only men experience alopecia.”

“While male pattern baldness is more commonly discussed, women are equally susceptible to alopecia due to hormonal imbalances, thyroid issues, and nutritional deficiencies,” says Dr Gangurde. Yes, ladies lose hair too and not just from brushing too hard.

Myth 2: “Stress alone is responsible for hair loss.”

While stress is definitely not good for your scalp’s health, it is not the lone cause. “Alopecia usually has multiple triggers, including genetics, autoimmune conditions, and underlying medical issues,” explains Dr Gangurde. Translation: stressing about stress causing hair fall might make things worse.

Myth 3: “Alopecia is always permanent and untreatable.”

This one might be the most damaging myth of all. “Many forms of hair loss, especially those caused by hormonal or nutritional factors, are reversible with timely medical intervention,” says Dr Gangurde. PRP therapy, medications, and lifestyle changes can all turn things around if you act early enough.

Do Not Just Shed Tears, Seek Help

If your hair has been thinning or falling out in clumps, resist the urge to DIY it with oils, serums, or social media hacks. “If you experience sudden or persistent hair loss, consult a dermatologist or trichologist promptly,” advises Dr Gangurde. “Early intervention can address the root cause, prevent progression, and in many cases, restore healthy hair growth.” Remember that alopecia is not just a surface-level issue. And with the right diagnosis, it is often more fixable than you think.

The 2025 flu season has turned out to be unlike any other in recent memory. This year, the flu season is marked by record-setting infections, multiple viral peaks, vaccine mismatches, and an overstretched healthcare system.

According to the Centers for Disease Control and Prevention (CDC), this year’s influenza activity is the most intense since the 2009 swine flu pandemic, with over 80 million estimated illnesses and rising. What’s driving this intensity, and what should the public know about prevention and symptom management?

Let’s break down what makes this flu season so severe and what it means for your health.

A Season Like No Other: What Makes 2025 Different?

In most years, flu activity in the U.S. typically follows a predictable pattern, starting in October, peaking between December and February, and fading by April. But the 2024–2025 season has defied that rhythm.

Cases surged past the national baseline in December and then, unexpectedly, peaked again in February, a second wave that blindsided doctors and public health experts.

As of March 2025, the CDC had reported an estimated 37 million influenza infections, 480,000 hospitalizations, and 21,000 deaths. Hospitalizations, in fact, reached their highest levels in 15 years.

One key driver? A mismatch between circulating flu strains and this year’s vaccine. The dominant strains: H1N1 and H3N2, accounted for more than 99% of cases.

H3N2, in particular, is known for mutating quickly and evading immune responses, and only about half of circulating H3N2 samples matched well with vaccine antibodies, according to CDC surveillance data.

Post-Pandemic Immune Gap

Another reason this year’s flu is hitting so hard: our immune systems are still catching up.

During the height of the COVID-19 pandemic, widespread masking, social distancing, and school closures suppressed not just SARS-CoV-2 but also seasonal flu and other common respiratory viruses. While that helped in the short term, it reduced community-level immunity over time, especially among children, who typically build natural resistance through repeated exposures.

“Young children who were toddlers or preschoolers during the pandemic missed early exposures to flu viruses,” explained experts at the nonprofit group Families Fighting Flu. “Now they’re in school, more socially active, and more vulnerable.”

The CDC reported a troubling spike in pediatric flu deaths this season with 216 fatalities, making it the deadliest flu season for children outside of a pandemic year. Neurological complications such as seizures and hallucinations also rose among young patients.

A Shift in Viral Dominance

Another unusual trend: COVID-19 has taken a back seat this winter

Unlike previous years when COVID-19 variants dominated respiratory illness charts, flu has surged ahead as the top driver of doctor visits and hospitalizations. This could be due to a shift in viral dominance, changing weather patterns, or differences in immunity buildup. According to the CDC, nearly 8% of all outpatient visits are currently for flu-like symptoms, much higher than what’s typical for this time of year.

Vaccine Fatigue and Gaps in Coverage

Vaccination remains the strongest tool we have to fight influenza, but uptake has been stagnant, or worse, declining, in key groups.

As of April 2025:

• Only 49.2% of children and 46.7% of adults had received the flu vaccine
• Among pregnant women, that number dropped to 38%
• Medicare beneficiaries aged 65+ had just 48.3% coverage
• And overall, nearly 9.2 million fewer doses were administered compared to the pre-pandemic 2019–2020 season

Barriers like vaccine hesitancy, misinformation, racial and ethnic disparities in healthcare access, and fewer flu shot clinics in rural areas continue to widen the gap.

What Are the Symptoms in 2025?

The 2025 flu has shown typical but often more intense symptoms than in previous years. Here’s what to look out for:

• Sudden onset fever
• Severe body aches and chills
• Sore throat and persistent cough
• Nasal congestion
• Diarrhea and vomiting (more frequent in children)
• Extreme fatigue
• Headache
• In some children, neurological symptoms like confusion or seizures

These symptoms may overlap with COVID-19 or RSV, but tend to come on faster and hit harder in flu cases this season.

How Long Do Symptoms Last?

For most healthy people, flu symptoms begin 1 to 4 days after exposure and typically last about 5 to 7 days. However, fatigue and cough may linger for up to two weeks.

You’re considered most contagious in the first 3 to 4 days after symptoms start but can continue to spread the virus up to a week later. The CDC recommends staying home until you’ve been fever-free for at least 24 hours without medication.

Vaccinated individuals may experience milder or shorter symptoms, but those with underlying conditions, young children, and older adults may have longer recoveries and higher risk of complications.

Can the Flu Cause Serious Health Problems?

Yes, especially in people with weakened immune systems, chronic illnesses, or no prior flu immunity.

Possible complications include:

• Pneumonia
• Ear and sinus infections
• Exacerbation of asthma or heart disease
• Life-threatening conditions requiring ICU care

This is why experts stress that prevention remains the best medicine.

How to Protect Yourself and Your Family

Here’s how to lower your risk during the remainder of the 2025 season:

• Get vaccinated, even now. It may still protect against circulating strains
• Wash your hands often with soap and water
• Avoid touching your face in public settings
• Cover your mouth and nose when coughing or sneezing
• Stay home if you’re unwell to prevent spreading the virus
