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.

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.

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.

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.

Endometrial Cancer

#endometrial cancer, #uterine cancer, #abnormal bleeding, #menopause, #obesity, #endometrium, #gynecologic cancer

Endometrial cancer develops in the endometrium, the tissue lining the inside of the uterus. It is a gynecologic cancer that is becoming increasingly common in Korea. In its early stages, it can cause symptoms such as abnormal vaginal bleeding, and when detected early, the outlook tends to be relatively favorable. If you have abnormal bleeding, please be sure to consult a medical specialist.

Finding the Right Exercise for You

#exercise prescription, #aerobic exercise, #strength training, #osteoporosis, #exercise for diabetes, #exercise for weight loss, #overweight, #swimming, #walking, #exercise stress test

Exercise can help maintain health and prevent disease, but exercise that does not suit your health status and goals can do more harm than good. Choose the type, intensity, and frequency of exercise to suit your condition, and if you have a medical condition, it is advisable to obtain an exercise prescription from a medical specialist.

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.

High-Risk Pregnancy

#high-risk pregnancy, #advanced maternal age pregnancy, #gestational hypertension, #preeclampsia, #gestational diabetes mellitus, #preterm birth, #preterm labor, #obstetrics and gynecology, #anxious feeling in the chest, #restlessness, #worrying for no reason

A high-risk pregnancy is a pregnancy with a higher chance than usual of adversely affecting the mother and the fetus. Advanced maternal age (35 or older) is one risk factor for a high-risk pregnancy. Recognizing your own risk factors and following your medical team's guidance can help lead to a good outcome.

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.

Kidney Transplant Process

#kidney transplantation, #kidney transplant, #living-donor kidney transplantation, #deceased-donor kidney transplantation, #immunosuppressants, #rejection, #end-stage kidney failure, #KONOS, #organ transplantation, #double vision, #overlapping images

Kidney transplantation is a surgery that transplants a healthy kidney into the body to replace a kidney that has lost its function. Unlike dialysis, it can restore most of the kidney's various functions (removing waste products, regulating electrolytes, secreting hormones that stimulate blood cell production, and others), which makes it one of the main treatment options for end-stage kidney failure. Whether and how to have a transplant depends on each patient's health condition, so please be sure to decide through consultation with 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.

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.

Osteoporosis

#osteoporosis, #bone density, #compression fracture, #menopause, #calcium, #vitamin D, #bisphosphonates, #fall prevention, #vertebral fracture, #femoral fracture, #dry cough, #persistent cough, #cough that won't stop

Osteoporosis is a condition in which bones become weaker and can break easily even from a minor impact. There are often no symptoms, and it is frequently discovered only after a fracture occurs. The risk is higher in postmenopausal women and older adults, so regular bone density testing and preventive lifestyle habits are important. Please be sure to discuss treatment options with a medical specialist.

Pancreatic Cancer

#pancreatic cancer, #chemotherapy, #abdominal CT, #jaundice, #chronic pancreatitis

Pancreatic cancer is cancer that develops in the pancreas, an organ located deep within the body. Because it produces few early symptoms, it is often found at a later stage. Please do not attempt to self-diagnose using an online encyclopedia; if you notice any concerning symptoms, be sure to see a gastroenterology or hepatobiliary-pancreatic surgery specialist.
