Know It in Advance, Be Prepared! Causes, Symptoms, and Prevention of Stroke

 Hello, it’s your health buddy! Let’s feel better together. Today, I’m here to share some symptom insights and helpful tips about Stroke. Let’s dive in!

Stroke is a sudden condition that can leave behind serious complications.
It doesn’t only occur in older people—it can affect anyone due to poor lifestyle habits. Just a few days ago, Pope Francis passed away due to heart failure caused by a stroke.

But the good news is that stroke is largely preventable through proper health management. So, knowing the signs and preparing in advance is more important than anything else.

In this post, we’ll go over the causes, symptoms, and prevention methods for stroke.


| What is a Stroke?


Stroke refers to a group of brain-related vascular disorders. It occurs when the blood flow in the brain is suddenly disrupted, leading to symptoms like loss of consciousness, motor issues, sensory problems, or disruption of vital functions. This can result in death or serious long-term effects.


| Types of Stroke by Cause


There are many causes of stroke, but most fall into two main categories: ischemic stroke and hemorrhagic stroke.

Ischemic stroke happens when a blood vessel in the brain is blocked, preventing blood flow to certain parts of the brain. This includes cerebral thrombosis, cerebral embolism, and transient ischemic attacks (TIA).
Hemorrhagic stroke occurs when a blood vessel bursts, blocking blood flow and putting pressure on the brain due to the bleeding.

Among ischemic strokes, cerebral thrombosis is the most common. It’s often caused by arteriosclerosis as we age, narrowing the arteries and reducing blood flow. When a clot made of cholesterol and platelets forms in the brain vessels, it gradually blocks the area, leading to stroke—especially in people with high blood pressure. It often occurs during rest.

Cerebral embolism is when a clot formed outside the brain travels to the brain and blocks a vessel suddenly. It usually happens in people with heart conditions like valve disease or arrhythmia.

Transient ischemic attacks (TIAs) are temporary disruptions in blood flow to the brain. They can cause short-term numbness or speech problems that recover within hours. However, repeated TIAs significantly increase the risk of a full stroke.

Hemorrhagic stroke has a high fatality rate. It often presents as sudden dizziness, headaches, vomiting, and limb numbness, sometimes leading to coma. It tends to happen during activity, especially in people with high blood pressure, stress, or physical strain, and occurs more often during the day than at night.

When the bleeding is limited to the membrane surrounding the brain, it’s called a subarachnoid hemorrhage. It often causes extreme headache and vomiting. It has an even higher fatality and recurrence rate than regular brain bleeding. It’s usually triggered by congenital brain aneurysms or malformations, and can also occur during bowel movements, lifting heavy objects, or intense physical activities—especially in younger people.


| 7 Rules to Prevent Stroke


  1. Manage your blood pressure.
    High blood pressure is the most dangerous risk factor. Ignoring it is like waiting for a stroke to happen.

  2. Maintain a healthy weight.
    Obesity and excess weight are key causes of stroke and other chronic diseases.

  3. Quit smoking.
    Once you quit, your risk for stroke, heart disease, and cancer starts to drop. After 1 year, the risk is cut by 50%, and after 5 years, it’s similar to a non-smoker’s.

  4. Exercise regularly.
    Those who exercise for at least 30 minutes a day are about 2.7 times less likely to suffer a stroke.

  5. Improve your diet.
    Eat low-sodium, low-calorie meals, and focus on vegetables and fish. Avoid salty or cholesterol-rich foods. Eating fruits, vegetables, and fish rich in folic acid and vitamins can reduce stroke risk by up to two-thirds.

  6. Stop drinking alcohol.
    While a glass of wine may aid circulation, habitual drinking—regardless of the type—raises stroke risk by three times.

  7. Keep your body and mind warm.
    Kind and happy people are less likely to experience strokes. Protecting your body temperature, especially in winter, is crucial, as stroke rates rise in colder weather.


| Foods That Help Prevent Stroke


Diet plays a crucial role in stroke prevention.
Avoid high-calorie animal fats and salty foods. Eat a balanced diet with fresh vegetables, seaweed, and whole grains.

Common foods in our diet that promote blood circulation and reduce stroke risk include garlic, onions, chives, and wild chives. These contain enzymes that transform into allicin, which increases HDL (good cholesterol) and lowers triglycerides and LDL (bad cholesterol).

Nutrients like anthocyanins, beta-carotene, vitamin A, and vitamin C found in black beans, pumpkin, tomatoes, carrots, tangerines, and lemons help blood flow, prevent blood vessel aging, and promote energy and vitality.

Salmon, mackerel, oysters, clams, shrimp, and seaweed are rich in DHA, omega-3 fatty acids, taurine, and tyrosine, all of which help prevent blood clots and arteriosclerosis.


| Changing Daily Habits

A stroke can destroy brain tissue, lead to death, or cause irreversible damage. That’s why ancient wisdom emphasized prevention over cure. Recognizing your personal risk factors and changing your lifestyle before a stroke occurs is essential.

Stroke can happen to anyone. Though it seems sudden, most strokes develop slowly over time.
Check your current lifestyle and environment. If you take active steps now, you can avoid the fear of stroke altogether.

Teenagers Longing to Be “Skin and Bones”

Hello, it’s your health buddy! Let’s feel better together. Today, I’m here to share some symptom insights and helpful tips about Skin and Bones. Let’s dive in!

A Rising Trend Among Teens


More and more teenagers today are idolizing extremely thin celebs and trying to become skinny through unhealthy dieting. Even teens with a normal weight are taking on extreme methods just to achieve a thinner appearance.

In one recent report, teenagers were found sharing photos of ultra-thin celebrities and "motivating" each other to achieve similar body shapes. They would take daily "body check" photos—what they call “eye-body” checks—to see who lost more weight or to encourage one another when progress seemed to stall.

The Dangerous Desire for “Skin and Bones”


While it’s great when young people adopt healthy eating and exercise habits to stay fit, the concern is that many are obsessed with rapidly losing weight at any cost. Among teens, the phrase “skin and bones” has become trendy—referring to admiring bodies that are thin enough to reveal bone structure.

This obsession can lead to eating disorders. Some teens force themselves to vomit after eating, experiencing symptoms of anorexia nervosa or bulimia nervosa.

An Unwelcome Guest in Any Season: Norovirus

Hello, it’s your health buddy! Let’s feel better together. Today, I’m here to share some symptom insights and helpful tips about Norovirus. Let’s dive in!

Norovirus infections are on the rise in the United States.
According to the Centers for Disease Control and Prevention (CDC), from August 1, 2024, to April 9, 2025, there were 2,407 norovirus outbreaks reported by states participating in the Norovirus Sentinel Testing and Tracking (NoroSTAT) network.
This number is significantly higher than the 1,230 outbreaks reported during the same period in the previous seasonal year.
The total number of outbreaks reported during the 2024–2025 seasonal year exceeds the range reported during the same period in the 2012–2020 and 2021–2024 seasonal years.
Norovirus outbreaks occur throughout the year but are most common from November to April.
Given this trend, health authorities anticipate that the number of cases may continue to rise.


What is Norovirus?


Norovirus is a contagious disease that spreads through contaminated food or contact with infected individuals.
During winter, it often spreads through seasonal ingredients like raw oysters or shellfish that haven’t been properly handled.
It can also be transmitted via droplets or stool from infected individuals.
Almost half (49.4%) of norovirus cases are reported in children aged 0–6, with another 18.9% occurring in those aged 7–18.
This means nearly 70% of infections occur in minors.
Outbreaks are especially common in group settings such as daycare centers, preschools, and schools.
While many assume norovirus is a summer issue due to food spoilage, it is actually nicknamed the “winter guest” because it survives even in extreme cold—down to -20°C (-4°F).


What Are the Symptoms of Norovirus?


Norovirus infection typically causes severe diarrhea, headache, and abdominal pain.
Some individuals may also experience low-grade fever or symptoms of dehydration for 1 to 3 days.
There is currently no vaccine for norovirus.
Although most people recover naturally without specific treatment, the symptoms can be distressing and require careful management.


Can It Be Prevented?


The first step in prevention is handwashing.
Wash hands thoroughly with soap under running water for at least 30 seconds.
Always wash hands after going outside, meeting others, using the restroom, coughing or sneezing, and blowing your nose.
It’s also important to cook food thoroughly.
When using kitchen tools like knives and cutting boards, sanitize them regularly and use different sets for vegetables, meat, and seafood.
Childcare facilities should ensure caregivers wash their hands thoroughly after changing diapers and before and after meals.


What If You’re Infected?

If someone becomes infected, it's important to isolate them from other household members.
After using the toilet, flush with the lid closed to prevent secondary infections.
Clean and disinfect items the infected person has touched using a 2:1 diluted bleach solution.
Norovirus is highly contagious—even touching objects handled by an infected person can lead to transmission.
Children and students should stay home from school or daycare for at least 48 hours to prevent spreading the virus to others.

What You Need to Know About Angelman Syndrome : Symptoms, Causes, Treatments, and Prevention Strategies

Hello, it’s your health buddy! Let’s feel better together. Today, I’m here to share some symptom insights and helpful tips about Angelman Syndrome. Let’s dive in!

Symptoms, Causes, Treatments, and Prevention Strategies


What is Angelman Syndrome?


Angelman Syndrome (AS) is a rare genetic disorder that affects brain development. It causes severe intellectual disabilities, difficulties in speech, problems with movement and balance, and unique behavioral characteristics.

It was first described by British pediatrician Dr. Harry Angelman in 1965. Most children start showing signs between 6 to 12 months, with clear developmental delays becoming more noticeable as they grow.

Thanks to advancements in genetic testing, early diagnosis is now more possible than ever.


Causes of Angelman Syndrome

This condition is linked to a problem with the UBE3A gene on chromosome 15, which plays a key role in brain function.


  • Maternal gene deletion (about 70% of cases)

  • Paternal uniparental disomy (2–4%)

  • Gene mutations or structural abnormalities

In AS, the brain doesn’t receive the protein it needs from the mother’s copy of the gene, leading to neurological issues.


Common Symptoms of Angelman Syndrome


Children with Angelman Syndrome may show:

  • Small head size (microcephaly)

  • Severe delays in speech

  • Motor coordination problems

  • Developmental delays in sitting, walking, etc.

  • Frequent smiling and a happy, excitable personality

  • Seizures (epilepsy) in over 80% of cases

  • Sleep disturbances

These symptoms can vary but are key in reaching a diagnosis.


Treatment Options

Although there's no cure yet, early intervention and supportive care can improve the quality of life.

  • Antiepileptic medications for seizure control

  • Speech therapy using AAC devices, gestures, and visual aids

  • Physical therapy to support mobility and balance

  • Behavioral therapy for improving social and focus skills

  • Early intervention programs to support development


Prevention and Support Strategies

While Angelman Syndrome cannot be fully prevented, here are steps to manage it early:

  • Genetic testing before pregnancy, especially with family history

  • Early diagnosis through observation of delays and professional testing

  • Emotional support for families—join support groups or talk to specialists

  • Regular rehabilitation therapy to maintain and improve function

Angelman Syndrome may be rare, but it deeply affects the lives of patients and their families.

What may first seem like a developmental delay could be something more. That’s why early diagnosis, ongoing therapy, and public awareness are so important.

If society becomes more understanding and support systems continue to grow, children with Angelman Syndrome will have a much brighter future.

Symptoms, Causes, Treatments, and Prognosis of Autism

Hello, it’s your health buddy! Let’s feel better together. Today, I’m here to share some symptom insights and helpful tips about Autism. Let’s dive in!

Autism is a developmental disorder where delays or abnormalities occur in areas such as social skills, language, and communication development compared to others.

Typically, signs begin to appear before the age of 3. These may include delayed language expression and comprehension, weak attachment behaviors with parents, and low interest in play compared to other children.


After age 3, symptoms may become more pronounced, such as a significant lack of interest in peers, repetitive behaviors, restricted play activities, and delays in cognitive development.

About 75% of children with autism also have intellectual disabilities, and seizure disorders are frequently observed as well.

Current research into the causes of autism includes neurological theories—such as increased total brain volume and abnormalities in the temporal lobe—and biochemical theories involving neurotransmitters.


The most recognizable symptoms of autism include difficulties in social interactions and impairments in language and communication.


Repetitive behaviors (known as "stimming") and emotional instability are also common. In most cases, autism is accompanied by some level of intellectual disability.


Effective treatment for autism requires an integrated approach, and outcomes are generally better when therapy begins at an early age.

During infancy, therapy should focus on strengthening attachment between the caregiver and child. In the toddler years, behavior-based therapy that promotes social interaction, along with play therapy and language training, is recommended.

Between the ages of 4 and 6, a variety of interventions should be applied, including group play therapy and social skills training. At this stage, medication may also be considered to address hyperactivity and repetitive behaviors.

In elementary school years, consistent support is needed to help children develop social skills, cognitive learning abilities, and verbal communication.


For younger children, it's more important for parents to actively interact with their child—taking into account their unique traits and preferences—than to rely heavily on medication.


Unproven treatments that make unrealistic promises are usually unhelpful. It's best to consult with a child psychiatrist to discuss treatments that have been shown to be effective.

Regular medical evaluations and proper medical care are also important throughout the treatment process.

Medications can be especially helpful for managing symptoms such as attention difficulties, behavioral regulation, emotional control, sleep issues, eating habits, and sensory processing challenges.

For example, Professor Temple Grandin, who is on the autism spectrum, underwent years of treatment during childhood and adolescence to reduce sensory sensitivity and improve emotional regulation. She has said that these treatments were highly beneficial.


Autism is generally a lifelong condition, meaning that continuous management is necessary even after early interventions.


However, if the individual has an IQ of 70 or above and possesses language skills similar to those of a 5–7-year-old, a much more favorable prognosis can be expected with consistent treatment.

Causes, Symptoms, and the Importance of Treating Obsessive-Compulsive Disorder (OCD)

Hello, it’s your health buddy! Let’s feel better together. Today, I’m here to share some symptom insights and helpful tips about Obsessive-Compulsive Disorder (OCD). Let’s dive in!

Janet (41), who lives in New York, finally visited a mental health clinic she had been meaning to go to for a long time. Whenever she got fixated on something, she found herself trapped in those thoughts all day long, unable to focus on work, and even losing sleep. She felt her symptoms were getting worse and finally gathered the courage to seek help.


Recently, she had a new bathroom sink installed due to a leak. But even after the repair, she couldn’t stop worrying that it might be leaking again. She kept checking it every few minutes, but the anxiety wouldn’t go away. There were even several times when she went back home from work just to make sure the air conditioner or heater was turned off. Sometimes, she would jump out of bed in the middle of the night to check if her belongings were in the right place, just to feel at ease.

She also experienced frequent anxiety about events that hadn’t even happened yet, excessive health worries, and insomnia triggered by endless “what if” thoughts. Although she had gone through this for over a decade, she dismissed it as part of her sensitive and perfectionist personality. But when her symptoms led to heart palpitations and dizziness, she finally consulted a specialist. She was diagnosed with a combination of OCD, anxiety disorder, and panic disorder. She is now undergoing treatment with two types of prescribed medication.


OCD is more common than we think — and easy to overlook


Most people experience a little bit of obsession or compulsiveness. But even when anxiety, depression, or obsessive thoughts become persistent, many people simply brush it off as a passing mood. If someone is known for being “a perfectionist” or “detail-oriented,” they might think it’s just their personality. However, if the symptoms continue to worsen, start affecting others, or interfere with daily life, that’s when it becomes a condition that requires professional help.


What exactly is OCD?


Simply put, OCD (Obsessive-Compulsive Disorder) involves repeated thoughts or actions that feel impossible to control. These compulsions create anxiety or discomfort unless acted upon. OCD is classified under what’s commonly known as “neuroses.”

A small amount of obsessive behavior can actually help in daily life, but when it becomes too intense, it turns into a disorder that not only affects the person suffering but also those around them. Although those with OCD often recognize that their actions or thoughts are irrational, they still feel compelled to act on them. Trying to suppress these impulses often worsens the anxiety.


How common is OCD?

OCD is relatively common. Lifetime prevalence is estimated at around 2–3%, and about 10% of psychiatric outpatients suffer from it. Despite being widespread, only a small number of those affected seek treatment. On average, people don’t get help until 7.5 years after their symptoms begin. It often starts during adolescence or early adulthood, but adult-onset is also possible.

It frequently coexists with other mental health conditions such as depression and social anxiety disorder. OCD may also occur alongside alcohol abuse, specific phobias, panic disorder, eating disorders, autism, and Tourette’s syndrome.


What are the symptoms of OCD?


Symptoms vary widely, but a common trait is repeating certain thoughts or behaviors even when the person knows they’re irrational. About 75% of people with OCD experience both obsessive thoughts and compulsive behaviors.

Common symptoms include:

  • Obsessive thoughts about contamination (e.g., repeated handwashing, avoiding “dirty” objects)

  • Doubting thoughts that lead to compulsive checking (e.g., checking locks, appliances)

  • Repetitive thoughts involving inappropriate sexual or violent content

  • A need for symmetry or precision (e.g., arranging objects in a specific order)

  • Intrusive, uncontrollable thoughts about existential matters like life, death, or religion


What causes OCD?

From a biological standpoint, OCD is thought to be linked to abnormal activity of serotonin in the brain. That’s why medications targeting serotonin are often used in treatment. On the other hand, OCD can also be learned behavior reinforced by trauma or repeated experiences. For example, someone who has experienced a serious accident might become obsessively focused on preventing a similar event.

So although it may seem like a psychological issue, OCD has strong biological roots.


When should you seek treatment?

This is an important question. Some people think their behavior is just a personality trait or a quirk, and they try to live with the discomfort. But if the distress is long-term and affects daily life, seeking help can make a significant difference.

If you suspect OCD, it's important to get evaluated and determine whether it’s a personality trait or something that requires treatment.

Initially, people may wonder if treatment can even help. But once they receive the right medications and therapy, many find that their symptoms improve and their quality of life changes dramatically. If you suspect even mild OCD, it’s worth visiting a clinic, speaking to a professional, and starting treatment tailored to your needs.

Feeling a Sudden Chest Pain or Tingling? Here's How to Prevent Heart Disease

Hello, it’s your health buddy! Let’s feel better together. Today, I’m here to share some symptom insights and helpful tips about Heart Disease. Let’s dive in!

I've been living alone for over 10 years now, and one thought keeps bothering me:
What if something dangerous happens to me, and there's no one nearby to call for help or take me to the hospital?
As the number of single-person households grows, I’m sure many others share the same concern.

Recently, Don Hasselbeck, a Super Bowl champion, passed away due to a heart attack.


Heart Disease Can Strike Anyone — Prevention Is Key


One of the scariest health threats these days is heart disease. Even people who appear healthy can suddenly lose their lives. Once the golden time passes, it’s often too late, and unless someone nearby performs CPR in time, the chances of survival are very slim.
It’s a terrifying condition — especially for someone like me who lives alone — because it often strikes without any clear warning signs and can happen to anyone.

That’s why I’ve decided to learn more about heart health and make an effort to eat heart-friendly foods regularly. Even healthy individuals can be caught off guard by heart disease.

Experts say that not only people in their 40s and older but also those in their 20s and 30s should pay attention to heart health.
Among various heart conditions, sudden cardiac arrest — which can lead to death without warning — is often caused by coronary artery disease due to atherosclerosis, accounting for about 80–90% of cases.
Annually, this affects about 1–2 out of every 1,000 people (0.1–0.2%).


Heart Disease Might Not Be Obvious, But It Does Show Signs


Even though symptoms may not be obvious, there are definitely early signs of heart problems.
Several months before a heart event, you may start to feel chest pain, shortness of breath, or extreme fatigue.

If you feel sudden tightness or pain in your chest, notice your heart beating unusually fast, or struggle to breathe even with light exercise or a short walk, it could be a warning sign.
This can happen at night, too. If you don’t usually suffer from sleep apnea but find yourself waking up frequently with heart palpitations, it’s worth considering a possible heart condition.

Also, if you have high or low blood pressure, experience frequent chest pain or palpitations, have ever fainted during daily life, have high cholesterol levels, or notice you’re out of breath or sweating heavily when lying down or sleeping, it’s time to get a heart checkup.
The same goes for people who smoke or drink heavily or have a family history of heart disease.


What to Do If You Feel Chest Pain


There are four main types of tests used to evaluate heart health:

  1. Heart MRI – This uses magnetic resonance imaging to assess heart function. It measures the size and function of the left and right ventricles and checks for valve regurgitation.

  2. Heart CT – A computed tomography scan that helps detect coronary artery narrowing or structural issues in the heart.

  3. Echocardiogram (Heart Ultrasound) – Useful for observing the heart’s structure and performance.

  4. Electrocardiogram (ECG or EKG) – This is the most basic and commonly performed test. It’s primarily used to diagnose arrhythmias and coronary artery diseases like angina and myocardial infarction.

If you suspect a heart issue, it’s best to visit a hospital and consult with a medical professional to determine which of these tests is most appropriate for your condition.


Exercise is, of course, one of the best ways to prevent heart disease.
Cutting back on alcohol and tobacco, and maintaining a regular routine, are just as important.
Avoid foods that are high in sodium or greasy, as they’re harmful to cardiovascular health.


Instead, try to eat more heart-friendly foods like strawberries, yogurt, vegetables, and red beets — all easy to include in your daily meals.
Unsweetened coffee and green tea are also known to help reduce the risk of heart disease.


If a family member or friend suddenly collapses from a heart attack, they must be taken to the hospital as quickly as possible.
After calling for emergency help, start CPR (cardiopulmonary resuscitation) right away.
It’s a good idea to learn basic first aid and CPR skills so you’re prepared for emergencies.
