Intermittent Fasting

#intermittent fasting, #diet, #weight loss, #calorie restriction, #blood sugar, #diabetes mellitus, #eating disorder, #pregnancy, #eating pattern, #anxious feeling in the chest, #restlessness, #worrying for no reason

Intermittent fasting is an eating pattern in which a person does not eat for a set period and eats only during allowed times. Short-term weight loss effects have been reported, but large-scale studies of long-term effects are still lacking. It calls for caution, or is not advisable, in certain groups such as people with diabetes mellitus, so please be sure to consult a medical specialist before starting.

Kidney Cancer

#kidney cancer, #renal cancer, #hematuria, #flank pain, #robotic surgery, #partial nephrectomy, #targeted therapy, #immunotherapy, #health checkup, #headache, #a splitting headache, #migraine, #back-of-head pain, #breathlessness, #difficulty breathing, #labored breathing, #feeling of suffocation, #dry cough, #persistent cough, #cough that won't stop, #blood in urine, #red urine, #bloody urine

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.

Kidney Transplantation

#kidney transplantation, #kidney transplant, #end-stage kidney failure, #immunosuppressants, #living-donor transplantation, #deceased-donor transplantation

Kidney transplantation is a surgery that transplants a healthy kidney into a patient with end-stage kidney failure, whose kidneys can no longer function properly. If the transplanted kidney functions normally, the patient may be freed from dialysis (a treatment that filters waste products from the blood using a machine), which can greatly improve quality of life. Ongoing care after surgery is very important, and please be sure to consult a medical specialist about anything related to transplantation.

Low-Sodium Salt Substitutes

#kidney disease, #kidney, #low-sodium diet, #salt substitute, #hyperkalemia, #weakness in arms and legs, #difficulty moving one side of the body

Reducing sodium intake is beneficial, but people with poor kidney function who use salt substitutes that provide a salty taste without medical guidance may face life-threatening risks, such as cardiac arrest. Be sure to consult a nephrologist before using them.

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, #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.

Peripheral Vascular Disease (Leg Vascular Disorders)

#peripheral arterial disease, #deep vein thrombosis, #varicose veins, #atherosclerosis, #edema, #body swelling, #facial swelling, #leg swelling, #swollen hands and feet

Peripheral vascular disease is a condition in which the blood vessels in the legs, far from the heart, become narrowed or blocked by blood clots (thrombi), and it can be a medical emergency. In serious cases, tissue in the leg can die and amputation may be necessary, so if your leg is severely swollen and painful, please consult a cardiology or vascular specialist immediately.

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.

Sleep apnea is a condition in which breathing repeatedly stops or becomes markedly reduced for 10 seconds or longer during sleep. If left untreated, it can worsen various systemic conditions such as high blood pressure, heart disease, stroke, and diabetes mellitus. It is not a simple sleeping habit but a condition that may require treatment. If you snore heavily or feel severe daytime sleepiness, please consult an ENT specialist.
