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.

Aortic Dissection

#Aortic dissection, #Chest pain, #Aorta, #Emergency, #High blood pressure, #Cardiothoracic surgery, #Vascular graft, #Stent, #Acute aortic dissection, #Chest ache, #Tight chest, #Chest tightness, #Weakness in arms or legs, #One-sided weakness

Aortic dissection is a medical emergency in which the wall of the aorta — the largest artery in the body — tears starting from its inner layer. It is marked by the sudden onset of severe, stabbing chest pain. Without prompt treatment, it can be life-threatening. If these symptoms occur, please call emergency services (119 in Korea) right away and go to the emergency room.

Chronic Kidney Disease (CKD)

#chronic kidney disease, #chronic renal failure, #kidney, #renal, #proteinuria, #glomerular filtration rate, #diabetic nephropathy, #lack of energy, #listlessness, #persistent tiredness, #body swelling, #facial swelling, #leg swelling, #swollen hands and feet

Chronic kidney disease (CKD) is a condition in which abnormalities in kidney function or structure persist for 3 months or longer. In the early stages there are often no particular symptoms, so the disease may go unnoticed and be discovered only after it has progressed considerably. People who have diabetes or high blood pressure, or who have a family history of kidney disease, need regular testing. If a health checkup reveals a kidney abnormality, please consult a medical specialist to confirm it.

Dementia Prevention

#dementia prevention, #three do's and three don'ts, #depression, #stress, #aerobic exercise

Dementia does not appear suddenly; it results from harmful changes that accumulate in the brain over a long period of time. Building good habits in daily life from a young age is the best way to help prevent it. Making an ongoing effort to protect one's own health is especially important. If you or a loved one notices signs of memory loss or other cognitive changes, please consult a medical specialist.

Diabetic Retinopathy

#Diabetic retinopathy, #Macular edema, #Retina, #Neovascularization, #Vitreous hemorrhage, #Retinal detachment, #Diabetes complications, #Fundus exam, #OCT, #Vision loss, #Blindness, #Body swelling, #Face swelling, #Leg swelling, #Swollen hands and feet, #Blurry eyes, #Trouble seeing, #Blurred vision

Diabetic retinopathy is a condition in which prolonged high blood sugar damages the tiny blood vessels and nerve tissue of the retina, the light-sensing layer inside the eye. About 15 to 30% of diabetic patients in Korea have this condition, and it is important to have an annual eye exam even without symptoms. Diabetic retinopathy is one of the three leading causes of blindness in Korea, so early detection and appropriate treatment are essential to protecting your vision.

Early-Onset Dementia (Young-Onset Dementia)

#early-onset dementia, #young-onset dementia, #alcohol-related dementia, #lifestyle diseases, #vascular dementia

Dementia is not a disease that affects only older adults. Dementia that develops at a relatively young age, between 45 and 65, is called early-onset (presenile) dementia. Because it tends to progress faster than dementia in older adults, please consult a medical specialist without delay if symptoms occur.

Glaucoma

#glaucoma, #optic nerve, #intraocular pressure, #visual field loss, #normal-tension glaucoma, #how to use eye drops, #headache, #splitting headache, #migraine, #pain at the back of the head, #lack of energy, #listlessness, #persistent tiredness

Glaucoma is a disease in which the optic nerve inside the eye is gradually damaged by high intraocular pressure or other factors, causing the visual field to narrow progressively. There are almost no symptoms in the early stage, so detection can be delayed, and rather than a cure, lifelong consistent management is important. Detecting it early through regular checkups and starting treatment is the best way to help prevent blindness.

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.

Kidney cancer is a malignant tumor that develops in the kidney. There are almost no symptoms in the early stages, so it is difficult to notice on your own, and in most cases it is found incidentally during a health checkup. Even without symptoms, it is important to detect it early through regular health checkups. If an abnormal finding is detected or you have any concerns, please be sure to consult a medical specialist.

Lower Extremity Arterial Disease (Peripheral Arterial Disease)

#lower extremity arterial disease, #peripheral arterial disease, #peripheral vascular disease, #leg pain, #atherosclerosis, #limb ischemia, #diabetic foot, #numbness in the hands and feet, #arm numbness, #tingling in the legs

Lower extremity arterial disease occurs when the arteries supplying blood to the legs become narrowed or blocked, reducing blood flow and causing symptoms such as pain, numbness, and delayed wound healing. Delayed diagnosis can lead to serious complications, so please be sure to consult a medical specialist if you experience any unusual symptoms in your legs.

Metabolic Syndrome

#Metabolic syndrome, #Insulin resistance, #Abdominal obesity, #Visceral fat, #High blood sugar, #High blood pressure, #Dyslipidemia, #Triglycerides, #HDL cholesterol, #Cardiovascular and cerebrovascular disease

Metabolic syndrome refers to having at least 3 of the following conditions together: high blood sugar, high blood pressure, dyslipidemia, and abdominal obesity. Having metabolic syndrome raises the risk of serious conditions such as heart attack, stroke, and type 2 diabetes. It can be effectively prevented and managed through early detection and lifestyle changes, so please check your own status through regular health checkups and evaluation by a medical specialist.

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.

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.

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.
