If these symptoms occur, please call emergency services (119 in Korea) right away and go to the emergency room.

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.

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.

#diabetic foot, #diabetic foot ulcer, #diabetic complications, #lower limb reconstruction, #amputation, #blood vessels, #neuropathy

Diabetic foot (diabetic foot ulcer) is a complication of diabetes in which an ulcer (sore) forms on the foot and does not heal well. If it is not detected early and treated appropriately, amputation of the foot or leg may become necessary. If you have diabetes, check your feet often, and do not leave even a small wound unattended; please consult a medical specialist.

Diabetic Retinopathy

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.

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 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.
