Sudden Hearing Loss: Causes, Symptoms, and Urgent Treatments You Must Know

Sudden Sensorineural Hearing Loss: A Sudden Warning Sign in Your Hearing

Recently, in a popular drama, the main character was diagnosed with a condition known as sudden sensorineural hearing loss (SSNHL).

This illness causes sudden hearing loss, often accompanied by dizziness.

---

How is Sudden Hearing Loss Diagnosed?

Not only in dramas but also in real life, sudden hearing loss occurs in more than 10 out of every 100,000 people each year. It is a condition that can also lead to depression due to the unexpected loss of hearing.

As the name suggests, sudden hearing loss comes on abruptly, usually within two to three days. It is typically defined as a loss of at least 30 decibels across three or more consecutive frequencies.

In many cases, people also experience tinnitus or dizziness, and they only discover the condition after visiting a doctor for those symptoms. It is not diagnosed simply because someone feels their hearing has declined.

Doctors confirm sudden hearing loss through hearing tests and MRI scans to rule out abnormalities in the central nervous system.

---

Unknown Causes and the Fear They Bring

In many cases, the exact cause of sudden hearing loss cannot be identified. Some cases are linked to tumors inside the ear, while others are caused by viruses or vascular problems. Exposure to sudden, extremely loud noises can also damage hearing and lead to the condition.

---

The Chances of It Affecting Both Ears

In the drama, the main character could not find the cause of their sudden hearing loss, and after being told by doctors that their hearing might not recover—or could even worsen—they fell into despair. Losing hearing in one ear and fearing that the other ear might also be affected left them believing they would never hear again.

In reality, however, sudden hearing loss in both ears is very rare, occurring in less than 5% of all patients. While losing hearing in one ear is serious, it does not mean both ears will definitely be affected.

If treatment is started promptly after hearing loss appears, there is a good chance of improvement depending on the underlying cause.

---

Treatment for Sudden Hearing Loss: A Race Against Time

In the drama, the main character’s treatment involved medication only. In real life, the most common treatment is steroid therapy, often combined with antiviral drugs or medications that improve blood circulation.

In the story, the character regained some hearing but decided to learn sign language and dedicate themselves to advocating for people with disabilities.

In reality, about one-third of patients regain normal hearing, while others may experience partial or complete permanent hearing loss. The longer treatment is delayed, the lower the chance of recovery. That is why it is critical to seek medical care immediately if you notice sudden changes in hearing.

Irritable Bowel Syndrome (IBS): Causes, Symptoms, and Lifestyle Tips for Relief

 

A Modern-Day Chronic Problem: Irritable Bowel Syndrome (IBS)

Sometimes, abdominal discomfort and pain occur without any clear cause. For many modern people living under stress and irregular routines, this is a common experience. Even without any noticeable disease in the colon, when bowel function does not work smoothly, daily life can be burdened with diarrhea, constipation, and abdominal pain. The discomfort is beyond imagination.

Although irritable bowel syndrome (IBS) is not a disease that directly threatens life, it affects almost every part of daily living and significantly lowers quality of life.

So, what causes it, and are there ways to prevent it?

---

Why Does Irritable Bowel Syndrome Occur?

IBS is a functional bowel disorder where there are no structural problems in the colon, yet chronic abdominal pain, discomfort, and bowel habit disturbances appear due to overly sensitive contraction and relaxation of the colon muscles.

The exact cause has not been fully identified, but in most cases, it is believed that chronic fatigue, excessive stress, and heavy workloads build up and eventually manifest as physical symptoms.

Other possible causes include changes in gut microbiota, genetic predisposition, and immune system irregularities.

---

The Main Symptoms of Irritable Bowel Syndrome

Symptoms vary from person to person, but the most common are gastrointestinal problems such as bowel habit changes, abdominal pain, bloating, and mucus in the stool. In fact, about 28% of patients visiting hospitals with digestive complaints are diagnosed with IBS.

Other symptoms may also appear, including headaches, irregular menstruation, urinary difficulties, heart palpitations, anxiety, restlessness, and even depression. These symptoms may interfere with daily life, but the condition itself is usually not dangerous.

The good news is that symptoms can often improve with proper diet, stress management, and regular exercise.

However, if abdominal pain persists despite lifestyle adjustments, or if you notice blood in the stool, sudden weight loss, or major changes in bowel habits, it may be a sign of another underlying condition. In such cases, consulting a medical specialist is strongly recommended.

---

Lifestyle Habits That Help Improve Symptoms

Since excessive stress and psychological anxiety are major factors that worsen IBS, managing stress is essential. Adjusting daily patterns to reduce stress triggers—or finding your own ways to relieve stress if change is not possible—can be very helpful.

Exercise is particularly effective, as it not only reduces stress but also improves bowel movement. Rather than starting with heavy workouts, it is better to maintain a consistent routine with light activities such as jogging or walking every day.

Keeping regular mealtimes and avoiding foods that irritate the colon are also important. Foods that ferment easily in the gut, such as oligosaccharides, disaccharides, and monosaccharides, can cause diarrhea or bloating. Overeating, binge drinking, and smoking should be avoided.

On the other hand, foods that may help ease IBS symptoms include fresh vegetables, fruits, and legumes.

Paronychia: Causes, Symptoms, Treatment, and Prevention of Nail Infections

 Don’t Pick at Hangnails! Beware of Paronychia

As the warm season approaches, more people are enjoying bright clothing and nail art. Decorating nails with colors, patterns, or even detailed designs has become so popular that many people now do it at home with ease. These days, not only women but also men are getting into nail art.

Applying nail polish to nails and toenails—made of dead cells—doesn’t directly harm our health. However, the process of trimming and preparing hands and feet for nail polish requires caution. If a wound gets infected, it can sometimes lead to a severe inflammation that requires surgical removal of the affected tissue.

---

A Small Sting, Then Suddenly Inflammation?

Sometimes people feel a throbbing pain around their finger. At first, it may seem like nothing more than discomfort from a short nail, but as swelling worsens, a visit to the doctor may reveal paronychia.

Paronychia is an infection of the skin around the nail, often caused by tearing hangnails or small injuries during nail care. When bacteria enter these wounds, inflammation occurs.

Unclean nail tools can also be the cause, as can environmental exposure to germs through small cuts. Those with weakened immune systems are more vulnerable, and people whose hands are frequently exposed to water—such as chefs or homemakers—are at higher risk since wounds can easily worsen in damp conditions.

---

Why You Shouldn’t Ignore Paronychia

In mild cases, inflammation from paronychia may settle down on its own. However, for people with weak immunity or underlying health conditions, the infection can progress quickly.

Many dismiss it as just a little swelling around the fingers or toes, but in severe cases, the pain can interfere with daily life. Early symptoms often include redness and swelling, but if left untreated, pus can accumulate in the wound.

Particularly with paronychia on the fingers, what looks like mild eczema can sometimes develop into greenish pus filling the skin around the nail, even changing its color.

---

Treatment for Paronychia

The most common treatment is prescribing antibiotics. Typically, antibiotics are taken for three to five days while monitoring progress.

If pus buildup is severe, a doctor may need to drain it under local anesthesia before continuing with antibiotics. Since bacteria are present in the pus, it’s important not to touch others with the infected hand to prevent spreading.

---

Everyday Habits to Prevent Recurrence

The challenge with paronychia is that once you’ve had it, it can easily recur whenever your body is tired or a new wound appears. That’s why prevention is key.

If you’ve had paronychia before, always clean and disinfect your hands thoroughly and dry them well when you get a cut around the fingers or toes. Wearing rubber gloves when working in water helps too, but since moisture can build up inside and worsen inflammation, it’s best to use gloves lined with cotton or add a cotton layer inside before wearing them.

Sleep Apnea: Why Snoring Can Be Dangerous and How to Treat It

It’s Not Just Simple Snoring, It’s Sleep Apnea

Not Just Simple Snoring, but Apnea

Are you dismissing your snoring as something trivial? If you wake up with a sore or scratchy throat, or you still feel tired even after a full night’s sleep, it could be a warning sign. This becomes more noticeable after your 30s when weight gain or lifestyle changes start to affect your sleep quality. In such cases, it might not just be simple fatigue—you may need to suspect sleep apnea.

Sleep apnea is diagnosed through a sleep study (polysomnography). If, during sleep, you snore and then stop breathing for more than 10 seconds, it is considered significant. Less than 5 episodes per hour is seen as normal, while over 30 is classified as severe sleep apnea. Studies show that about 15% of adults in Korea suffer from sleep apnea, and most of them are patients with obstructive sleep apnea, caused when the airway collapses or becomes blocked during sleep.

---

What Causes Sleep Apnea?

If you were not a snorer before but suddenly got diagnosed with sleep apnea, it usually means airflow is not passing smoothly through your nose and throat. Drinking alcohol frequently or simply aging can reduce the muscle tone of the throat tissues, increasing the chance of snoring and sleep apnea.

In addition, chronic fatigue or stress can cause your muscles to relax even more, leading to apnea episodes. Allergies, sinus infections, or other nasal blockages can also trigger it. Being overweight is another strong risk factor—extra fat around the neck can narrow the airway, causing blockage during sleep.

---

Could I Have Sleep Apnea?

Often, it’s family or friends who notice the symptoms first, but it’s not easy to judge by yourself whether you are a patient. If you experience any of the following signs, you may need to suspect sleep apnea:

1. You snore loudly.

2. You gasp or choke during sleep.

3. You wake up with a sore throat.

4. You urinate frequently at night.

5. You often wake up sweating.

6. Your throat feels very dry and irritated in the morning.

7. You feel fatigued all day long.

8. You notice reduced memory or concentration.

9. You experience erectile dysfunction or reduced libido.

10. You have trouble sleeping and your weight keeps increasing.

If you checked five or more of these symptoms, there is a strong chance of sleep apnea. However, for a clear diagnosis, you should undergo a sleep study.

---

Sleep Apnea Can Lead to Sudden Death

Sleep apnea is far from being just snoring. On the surface, it can make people socially withdrawn. Many avoid sleeping next to their partners, leading to conflicts in relationships. Beyond that, it reduces concentration, affects work performance, and may even contribute to cognitive decline or depression.

More seriously, sleep apnea can rapidly raise blood sugar and blood pressure. Normally, during sleep, both the body and the brain rest, and blood sugar levels naturally drop. However, in sleep apnea patients, the airway repeatedly collapses, forcing the brain to wake up. This consumes more energy and glucose, which causes blood sugar to rise. At the same time, lack of oxygen in the body makes the cardiovascular system work harder, raising blood pressure.

Studies show that 50% of patients with obstructive sleep apnea also have high blood pressure, and about 30% of high blood pressure patients also suffer from sleep apnea. These complications can become so severe that, in extreme cases, sleep apnea may even lead to sudden death. Clearly, it is not something to ignore as “just snoring.”

---

How to Treat Sleep Apnea

If you suspect sleep apnea, the first step is to visit an ENT (ear, nose, and throat) specialist and get a consultation. A sleep study will confirm whether or not you have apnea. If diagnosed, there are two main treatment options: using a CPAP (Continuous Positive Airway Pressure) machine or undergoing surgery.

Surgery, however, is not always perfect. Options include removing the uvula to tighten the throat area, performing laser-assisted uvulopalatoplasty, or nasal surgery to open blocked passages. But the success rate is only about 50%, and symptoms often recur. Because of this, doctors usually recommend CPAP treatment first.

The CPAP device is worn during sleep and works by blowing air into the airway, preventing it from collapsing. It looks somewhat similar to an oxygen mask. There are cases where patients’ apnea frequency dropped from 60 times to almost zero after six months of using CPAP. However, many patients find it inconvenient since it has to be worn every night, carried even on trips, and often requires sleeping separately from family members. Still, it is currently the most effective treatment and is covered by health insurance.

As the saying goes, “Sleep is the best medicine.” Conversely, poor sleep can lead to countless health problems. The exact cause of sleep apnea is not clear, and not everyone with a large body frame gets it. Unfortunately, there is no perfect cure. Surgery results are uncertain, and aside from using CPAP and losing weight, treatment options remain limited. Some oral medications are under development abroad, but they are not yet available.

Despite being a dangerous condition, with early diagnosis and consistent management, you can lower the risks. Don’t dismiss snoring as harmless—getting tested and prepared early can help prevent life-threatening situations.

Lung Cancer: Key Causes, Symptoms & Prevention

Lung Cancer: A Silent Threat and How to Protect Yourself

Lung cancer is the leading cause of cancer-related deaths globally. According to the International Agency for Research on Cancer, in 2022 there were nearly 2.5 million new lung cancer cases, making it the most commonly diagnosed cancer worldwide . Even more alarmingly, over 1.8 million people lost their lives to lung cancer, accounting for roughly 19% of all cancer deaths.

Despite these staggering numbers, lung cancer’s early stages often remain symptom-free. Let’s delve into why early detection is so challenging and what you can do to safeguard your health.

---

Why Early Detection of Lung Cancer Is So Difficult

The lungs are centrally located and essential for breathing—taking in oxygen and expelling carbon dioxide. Lung cancer refers to malignant tumors originating in the lungs. It’s typically categorized as:

• Primary lung cancer (originating in the lung)

• Metastatic lung cancer (spreading from another organ)

By the time symptoms emerge or diagnosis occurs, the disease has often reached stage 3 or 4—even stage 4, in some cases, presents without symptoms. Indeed, about 15% of lung cancer cases are found incidentally when no symptoms are present.

This “silent” presentation is due to lungs lacking pain-sensing nerves. Consequently, significant internal damage may occur without triggering any pain or discomfort.

---

Common Symptoms When Lung Cancer Progresses

As the cancer advances, typical symptoms may include:

• Persistent cough (in ~50–75% of cases)

• Coughing blood (hemoptysis; ~25–50%)

• Chest pain (~20%)

• Difficulty breathing (~25%) 

Because these symptoms overlap with other lung conditions, recognizing lung cancer based on symptoms alone can be difficult.

---

The Central Role of Smoking—and Other Risk Factors

Smoking remains the foremost cause of lung cancer, with tobacco smoke containing thousands of harmful chemicals, including over 60 known carcinogens. Approximately 70–85% of lung cancer cases are linked to smoking. Risk increases with the duration and intensity of smoking, the depth of inhalation, and earlier initiation.

Secondhand smoke also raises risk—studies show prolonged exposure increases lung cancer risk by around 1.5 times.

Additional risk factors include:

• Long-term exposure to air pollution, asbestos, and radon

• Occupational hazards such as industrial fumes

• A family history of lung cancer—which doubles to triples the risk for those affected 

• Around 15% of lung cancers occur in never-smokers, often due to other environmental or genetic factors 

---

Early Detection Saves Lives

Since early lung cancer often goes unnoticed, regular health screenings are vital for early detection. Early diagnosis can significantly improve survival rates and quality of life.

If you have a family history of lung cancer, it’s recommended to undergo screenings more frequently. And if you smoke—quitting as soon as possible dramatically lowers your risk. However, even after quitting, it may take up to 20 years for your risk to approach that of non-smokers, and some risk remains elevated. Research also suggests that women face a 1.5 times higher risk of developing lung cancer than men for the same level of exposure.

---

Reduce Risk Even in Daily Life

Take simple steps to protect your lungs:

• Ensure good ventilation while cooking, especially in enclosed kitchens

• Use exhaust fans or keep windows open to reduce exposure to harmful smoke
  
  

---

In summary, lung cancer’s deadliness lies in its silence. Prevention, awareness, and early detection are your greatest allies. Stay informed and proactive—your health is worth it.

Sarcopenia: The Silent Muscle Loss of Aging and How to Prevent It

 

Unwelcome Guest of Old Age: How to Prevent Sarcopenia

As we enter the era of 100-year lifespans, maintaining health in old age has become a major concern.
Sarcopenia—the loss of muscle mass and strength—not only drains your energy and disrupts physical balance, but can also lead to mobility issues, diabetes, metabolic disorders, and other age-related diseases, threatening a healthy life in your later years.
The earlier you start prevention, the better. Let’s explore how to protect yourself from sarcopenia.

---

Why Does Sarcopenia Occur?

Sarcopenia is a condition where skeletal muscle—such as those in the legs—shrinks significantly in size and strength.
As we age, the number of muscle fibers, often referred to as the body’s “energy reservoir,” begins to decline. This process starts as early as your 30s, gradually reducing muscle mass. From your 50s, you lose about 1–2% each year. By your 70s, the rate of loss accelerates, potentially cutting muscle mass to half its original level—making extra caution essential in later years.

The causes of sarcopenia are varied. Lack of exercise and poor nutrition are major contributors, along with chronic inflammation, hormonal imbalances, and reduced protein synthesis capacity.

---

What Happens When Muscle Declines?

As sarcopenia progresses, you may experience:

1. Reduced energy storage, leading to frequent fatigue.

2. Lower basal metabolic rate, causing frequent weight fluctuations and easier fat gain.

3. Greater blood sugar fluctuations, making glucose control difficult for diabetics.

4. Increased dizziness, falls, and weakened bones.

5. Slower physical responses, poor balance, and higher fall risk.

※ Decreased grip strength or walking speed can also be early warning signs.

---

Why Sarcopenia Prevention Matters

There is currently no definitive cure for sarcopenia.
That’s why prevention and management are essential—through proper nutrition, regular exercise, and lifestyle habits.
If you’re over 60, start your sarcopenia prevention routine as soon as possible to ensure a healthy, active old age.

---

How to Protect Your Muscles and Prevent Sarcopenia

1. Combine Aerobic and Strength Training
Incorporate daily aerobic activities like brisk walking, jogging, or cycling, along with strength exercises at least twice a week—such as wall push-ups or seated leg extensions.
For older adults, safety comes first: choose exercises suited to your fitness level, do proper warm-up and cool-down, and avoid sudden or overly strenuous movements.

2. Get Enough Vitamin D
Studies show that adequate Vitamin D intake in old age can help prevent muscle loss as effectively as exercise.
According to the Korea Disease Control and Prevention Agency, maintaining optimal blood Vitamin D levels significantly reduces age-related sarcopenia risk.
You can get Vitamin D naturally by spending about 20 minutes in the sun daily, or from foods like tuna, salmon, mackerel, cheese, and mushrooms.

3. Maintain Adequate Protein Intake
From your 30s—when muscle loss begins—make daily protein intake a priority.
Aim for 1–1.2g per kg of body weight. For example, if you weigh 60kg, consume about 60g of protein per day.
Without enough protein, exercising alone can actually speed up muscle loss, so consistency is key.

4. Consume Leucine, an Essential Amino Acid for Muscle Building
Leucine cannot be produced by the body and must be obtained through food.
Foods rich in leucine include eggs, milk, bananas, nuts, black beans, and soy products.

7 Essential Nutrients You Must Take After 40 to Stay Healthy and Prevent Disease

7 Essential Nutrients You Must Take After Your 40s!

While balanced nutrition is important at every age, there are specific nutrients you need to pay closer attention to once you hit your 40s. As we age, our bodies gradually lose the ability to produce or absorb nutrients efficiently. After menopause or during midlife, the risk of developing conditions like heart disease, stroke, osteoporosis, diabetes, and high blood pressure significantly increases. Let’s explore the must-have nutrients for a long and healthy life.

---

To Prevent Osteoporosis – A Common Midlife Condition:

Calcium and Vitamin D

One of the most important health concerns for middle-aged women after menopause is osteoporosis. During the 3 to 5 years following menopause, bone density starts to decline rapidly. This makes bones thinner and more fragile, increasing the risk of fractures—even from light impact or minor injuries. If the spine or hip bone breaks, it can significantly affect mobility and lead to other complications. The same risk also applies to men going through andropause.

The two most essential nutrients for preventing osteoporosis are calcium and vitamin D. Women over 50 are recommended to consume 1200mg of calcium daily. If it’s hard to get enough from food alone, calcium supplements can help. Calcium not only supports bone health but also helps reduce fat absorption, boosts fat metabolism, and calms the muscles and nerves. Taking calcium after meals can improve absorption because stomach acid helps calcium dissolve better.

But calcium alone isn't enough. From the late 30s onward, bones lose calcium faster than they store it. Vitamin D plays a key role in slowing this down. It helps your body absorb calcium and supports muscle function, so it’s essential to get enough. While vitamin D is naturally produced when your skin is exposed to sunlight, the skin's ability to create vitamin D decreases with age—making supplements important.

To Prevent the World’s Leading Cause of Death: Cardiovascular Disease

Omega-3 Fatty Acids and Coenzyme Q10

Cardiovascular diseases are the number one cause of death worldwide. As we age, it becomes even more important to take care of our blood vessels. Aging can weaken blood vessel walls, increasing the risk of heart and brain diseases. When waste builds up in the blood vessels supplying the brain, it can even cause vascular dementia.

One of the key nutrients for protecting your blood vessels is omega-3 fatty acids. Omega-3 strengthens blood vessels, lowers triglyceride levels, and helps blood flow smoothly. It also helps reduce blood pressure and heart rate, lowering the risk of heart-related illnesses.

Omega-3 is also crucial for eye health. The DHA in omega-3 forms a key part of your eye’s nerve and retina cells, while EPA helps reduce inflammation. Taking omega-3 regularly can help prevent eye conditions like dry eyes and macular degeneration. However, omega-3 can’t be made by the body, so you need to get it from food or supplements.

Along with omega-3, another nutrient that helps manage blood pressure is Coenzyme Q10. This is a vital component in the mitochondria, where your cells produce energy. Unfortunately, your body’s ability to produce CoQ10 declines with age, so regular supplementation is recommended.

---

To Strengthen Immunity and Prevent Dementia:

B Vitamins

To Slow Down Aging:

Vitamin C and Collagen

After 40, taking a wide range of vitamins becomes more important. Among them, B vitamins are especially essential for supporting immune function and metabolism. As we age, our metabolism slows down and immunity weakens. B vitamins help process carbohydrates and fats in the body, assisting with fat reduction and supporting brain health.

One of the most crucial B vitamins is Vitamin B12. When we eat too much protein-rich food like meat, a substance called homocysteine builds up in the body. This increases the risk of blood clots and oxidative damage, raising the risk of stroke and damaging brain cells, which leads to memory loss. Vitamin B12 helps lower homocysteine levels, which may help reduce the risk of dementia.

Postmenopausal women with low vitamin B12 levels are also more prone to anemia. Another key B vitamin is folate, often known for being essential during pregnancy, but it’s just as important for older adults. Folate is necessary for making red blood cells, and deficiency can lead to symptoms like weight loss and anemia. It can also increase homocysteine levels, raising the risk of heart disease.

You should also consistently take Vitamin C, a powerful antioxidant that removes harmful free radicals—the major cause of aging. Vitamin C helps your body produce collagen, so taking them together boosts absorption and promotes healthy skin and joints.
