Biological Age and Health Age

#biological age, #health age, #physiological age, #aging, #health checkup, #lifestyle habits, #metabolism, #health risk assessment

Biological age is an estimate of the degree of aging, expressed as a number, based on health indicators such as blood pressure, blood glucose, and liver function. Health age is an age that reflects health risk factors such as lifestyle habits and family history. Neither measure is a definitive diagnostic tool, but both can be used to motivate people to adopt healthier lifestyle habits.

Cerebral Hemorrhage

#cerebral hemorrhage, #stroke, #cerebral infarction, #intracranial pressure, #blood pressure management, #emergency surgery, #headache, #splitting headache, #migraine, #pain at the back of the head, #body swelling, #facial swelling, #leg swelling, #swollen hands and feet, #weakness in the arms or legs, #difficulty moving one side of the body

Cerebral hemorrhage is a medical emergency in which a blood vessel in the brain ruptures and bleeding occurs. Blood pressure management is the most important way to prevent it, and if symptoms occur, you should go to the emergency room immediately.

Cerebrovascular Disease (Stroke)

#stroke, #cerebral infarction, #cerebral hemorrhage, #thrombolysis, #thrombectomy, #cerebrovascular disease, #winter stroke, #first aid, #post-stroke sequelae, #multidisciplinary care, #headache, #splitting headache, #migraine, #pain at the back of the head, #lightheadedness, #spinning sensation, #unsteadiness, #vision going dark, #weakness in the arms or legs, #difficulty moving one side of the body

Cerebrovascular disease (stroke) is a condition in which a blood vessel in the brain becomes blocked or ruptures, causing brain damage. To minimize aftereffects, prompt emergency response is most important, under the principle that 'time is brain.' The risk of stroke is especially high in winter and during seasonal changes, so please follow the prevention guidelines carefully.

Childhood Obesity

#childhood obesity, #adolescent obesity, #pediatric metabolic syndrome, #growth, #weight management, #eating habits, #exercise, #loose stools, #watery diarrhea, #frequent bathroom visits

Childhood obesity is a condition in which excess body fat accumulates in children and adolescents. It may continue into adulthood and increases the risk of high blood pressure, diabetes, and hyperlipidemia. Early management is important, especially at younger ages. Please talk with a medical specialist and follow a plan that combines dietary changes, exercise, and lifestyle improvements.

Coronary Artery Disease (Angina and Myocardial Infarction)

#coronary artery disease, #angina, #myocardial infarction, #coronary angiography, #stent, #chest pain, #heart, #collapsing, #loss of consciousness, #passing out, #breathlessness, #difficulty breathing, #labored breathing, #feeling of suffocation, #indigestion, #bloating, #poor digestion, #anxious feeling in the chest, #restlessness, #worrying for no reason

Coronary artery disease is a condition that occurs when the coronary arteries, which supply blood to the heart, become narrowed or blocked. Angina and myocardial infarction are the main types, and myocardial infarction is an emergency that needs prompt treatment. If you have symptoms such as chest pain, seek immediate medical attention.

Heart Failure

#heart failure, #dyspnea, #edema, #heart, #obesity, #high blood pressure, #myocardial infarction, #heart medication, #heart failure prevention, #breathlessness, #difficulty breathing, #labored breathing, #feeling of suffocation, #body swelling, #facial swelling, #leg swelling, #swelling in hands and feet

Heart failure is a condition in which the heart cannot supply as much blood as the body needs. With appropriate treatment and management, it is possible to maintain daily life, but if left untreated, symptoms such as shortness of breath and swelling can worsen. If you have risk factors such as high blood pressure, diabetes mellitus, or obesity, please see a medical specialist regularly.

Hypertension (High Blood Pressure)

#hypertension, #blood pressure, #blood pressure medication, #sodium, #arteriosclerosis, #antihypertensive drugs, #essential hypertension, #headache, #a splitting headache, #migraine, #back-of-head pain

Hypertension is a condition in which blood pressure, the force exerted on the walls of the blood vessels when the heart pumps out blood, stays persistently high; it is classified as a systolic blood pressure of 140 mmHg or higher or a diastolic blood pressure of 90 mmHg or higher. Hypertension often causes no symptoms, so it is called the "silent killer." If left untreated, it can lead to serious complications such as stroke, heart disease, and kidney disease, so evaluation by a medical specialist and steady management are needed.

Hypertension and Diet Management

#hypertension, #blood pressure, #blood pressure medication, #sodium, #hyperlipidemia, #diabetes mellitus, #heart

Hypertension is a condition in which blood pressure stays persistently high. Blood pressure is the force exerted on the walls of the blood vessels when the heart pumps out blood. Hypertension often causes no symptoms, so it is also called the "silent killer." If left untreated, it can lead to complications in the heart, brain, and kidneys, so evaluation by a medical specialist and steady management are needed.

Liver Cirrhosis

#liver cirrhosis, #cirrhosis, #liver disease, #hepatitis B, #hepatitis C, #ascites, #jaundice, #hepatic encephalopathy, #variceal bleeding, #body swelling, #facial swelling, #leg swelling, #swollen hands and feet

Liver cirrhosis refers to a condition in which the liver has been damaged for a long time by various causes and has become hard. It is also called 'gangyeongbyeon' in Korean. When the liver hardens, it cannot perform its functions well. For an accurate diagnosis and treatment, please consult a medical specialist.

Retinal Artery Occlusion

#retinal artery occlusion, #retina, #decreased vision, #eye stroke, #central retinal artery occlusion, #high blood pressure, #diabetes, #blurry vision, #difficulty seeing, #hazy vision

Retinal artery occlusion is a condition in which the artery that supplies blood to the retina is suddenly blocked. Like a stroke, in which a blood vessel in the brain is blocked, it damages the nerve cells involved in vision, and it is sometimes called an 'eye stroke.' If sudden vision loss occurs, seek immediate medical attention at an emergency room or ophthalmology department.

Schizophrenia

Schizophrenia is a major mental illness in which the ability to distinguish reality from one's own thoughts and perceptions is impaired. In Korean, the disorder was previously called jeongsinbunyeolbyeong (literally, "split-mind disease") but was renamed johyeonbyeong in 2011; the new term means "tuning the strings," reflecting the idea that mental confusion arises when the brain's neural signaling is not properly tuned. With appropriate treatment and management, people with schizophrenia can maintain daily functioning.

Statin-Associated Immune-Mediated Necrotizing Myopathy

#statin, #myopathy, #IMNM, #hyperlipidemia, #muscle weakness, #immunosuppression, #autoantibody, #CK

In rare cases, people taking a statin (a medication for hyperlipidemia) can develop immune-mediated necrotizing myopathy, in which muscle weakness continues even after the medication is stopped. If weakness in both thighs or shoulders continues for a week or longer while taking a statin, please be sure to consult a medical specialist.

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.
