Angina (Angina Pectoris)

#angina, #chest pain, #myocardial infarction, #coronary artery, #atherosclerosis, #stent, #sudden death

Angina is a cardiovascular condition in which the coronary arteries — the blood vessels that supply oxygen and nutrients to the heart — become narrowed, causing a dull chest pain. Because heart disease can be a major cause of sudden death, if you feel chest discomfort that is different from what you normally experience, please do not delay in consulting a medical specialist.

Diabetes Complications and Management

#Diabetes, #Diabetes complications, #Blood sugar control, #HbA1c, #Retinopathy, #Nephropathy, #Neuropathy, #Cardiovascular disease

When blood sugar remains high over time, diabetes can lead to complications in several organs, including the eyes, kidneys, nerves, and cardiovascular system. Preventing these complications requires blood sugar control along with managing blood pressure and cholesterol/lipid levels, as well as regular complication screening. Please continue treatment consistently with your doctor.

Fine Dust (Particulate Matter) and Health

#particulate matter, #fine particulate matter (PM2.5), #Asian dust (yellow dust), #respiratory system, #mask, #KF80, #KF94, #asthma, #air pollution, #dry cough, #minor cough, #persistent cough

Fine dust consists of tiny particles floating in the air. It directly affects the respiratory tract, including the nose, bronchi, and lungs, and can also harm the whole body, including the heart, brain, and blood vessels, through the bloodstream. Long-term exposure increases the risk of asthma, reduced lung function, and cardiovascular and cerebrovascular disease. On days when fine dust levels are high, limit outdoor activities, and people at high risk are advised to wear a health protection mask.

The flu (influenza) is a respiratory infection caused by the influenza virus, and its cause and symptoms differ from those of the common cold. Annual vaccination is recommended each fall (September to November). If you develop symptoms such as high fever or severe muscle aches, please see a medical specialist.

Heat Waves and Heart Health

#heat wave, #sudden cardiac death, #heat stroke, #heat-related illness, #heart attack, #angina, #cardiac arrest, #arrhythmia, #hydration, #summer health, #dizziness, #feeling faint, #unsteadiness, #vision going dark, #fainting, #loss of consciousness, #syncope, #breath holding, #difficulty breathing, #shortness of breath, #choking sensation

Extreme heat raises the risk of angina, heart attack, and cardiac arrest by increasing heart rate, promoting blood clotting, and placing added strain on the heart. Older adults age 65 and older, people with cardiovascular disease, and those with chronic conditions such as high blood pressure or diabetes need to be especially careful. On days when a heat wave warning is issued, please stay active indoors for safety.

Obesity

#obesity, #body mass index, #BMI, #abdominal obesity, #severe obesity, #anti-obesity medication, #liraglutide, #bariatric (metabolic) surgery, #fatty liver, #metabolic syndrome

Obesity is a chronic disease in which excess body fat accumulates, and it can cause various complications, such as high blood pressure, diabetes mellitus, dyslipidemia, and arthritis. Under Asia-Pacific criteria, obesity is diagnosed when body mass index (BMI) is 25 kg/m² or higher, and, like high blood pressure and diabetes, it is a condition that needs lifelong management. Please consult a medical specialist before deciding on a treatment method.

Gum disease (periodontal disease), marked by bleeding and swollen gums, is not limited to the mouth — it can worsen systemic conditions such as dementia, heart disease, and diabetes. Regular visits to a periodontal specialist and routine dental scaling are essential.

Secondary amenorrhea refers to the absence of menstruation for three months or longer in a woman who previously had normal menstrual cycles. It has various causes, and if left unaddressed for a long time, it can affect overall health. Because treatment differs depending on the cause, evaluation by a medical specialist is needed.

Smoking, Health, and Quitting Smoking

#Smoking, #Smoking cessation, #E-cigarettes, #Nicotine, #Tar, #Lung cancer, #Cardiovascular disease, #COPD, #Smoking cessation medication, #Nicotine addiction, #Weakness in arms or legs, #One-sided weakness, #Chest anxiety, #Restlessness, #Unexplained worry, #Feeling down, #Lack of motivation, #Not wanting to do anything

Both regular cigarettes and e-cigarettes are harmful to health. Smoking raises the risk of many conditions, including lung cancer and other cancers, cardiovascular disease, and chronic obstructive pulmonary disease (COPD). Quitting smoking is not easy, but getting help from a medical specialist makes success more likely. If you've decided to quit, please work with a healthcare team rather than trying on your own.

Stroke

#stroke, #dementia, #vascular dementia, #high blood pressure, #snoring, #weakness in the arms or legs, #difficulty moving one side of the body

Stroke is a medical emergency that occurs when a blood vessel in the brain becomes blocked or ruptures. A blocked blood vessel is called a cerebral infarction, and a ruptured one is called a cerebral hemorrhage. If symptoms appear, going to the emergency room immediately is the most important way to reduce aftereffects. Stroke is also closely related to dementia. The main symptom of stroke is the loss of a specific bodily function, such as paralysis of the arms or legs. The most important factor in treatment is the golden time (the critical time window for treatment), so please be sure to consult a medical specialist for an accurate diagnosis. If abnormal symptoms appear, call 119 (Korea's emergency number) or go to the emergency room immediately.

Sugar Intake and Health

#Sugar, #Table sugar, #Blood sugar, #Obesity, #Carbohydrates, #Simple sugars, #Diabetes prevention, #Diet

Simple sugars, such as table sugar, need little digestion and are absorbed into the bloodstream quickly, which can cause blood sugar to rise sharply. Excessive intake raises the risk of obesity and metabolic disease. The World Health Organization (WHO) recommends limiting free sugars to less than 10% of daily energy intake and suggests a further reduction to less than 5% for additional health benefits. Free sugars include added sugars and sugars naturally present in honey, syrups, and fruit juices.
