Abdominal Wall Hernia

#abdominal wall hernia, #hernia, #laparoscopy, #robotic surgery, #minimally invasive surgery, #bowel obstruction, #abdominal surgery, #stomachache, #abdominal pain, #belly ache, #gut pain, #dry cough, #minor cough, #persistent cough, #unable to pass stool, #difficulty passing stool, #hard stools

An abdominal wall hernia is a condition in which the abdominal wall around a surgical incision weakens after abdominal surgery, allowing tissue from inside the abdominal cavity to push out. Early detection and surgery may allow a faster recovery. If you feel an unusual lump in the abdomen or develop sudden abdominal pain, please consult 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.

Benign Prostatic Hyperplasia (BPH)

#benign prostatic hyperplasia, #prostate, #lower urinary tract symptoms, #frequent urination, #nocturia, #urinary urgency, #sense of incomplete bladder emptying, #acute urinary retention, #alpha-blocker, #transurethral resection of the prostate, #headache, #a splitting headache, #migraine, #back-of-head pain, #urinating frequently, #frequent trips to the bathroom, #blood in urine, #red urine, #bloody urine

Benign prostatic hyperplasia (BPH) is a very common condition in men in which the prostate enlarges with age, narrowing the urethra and causing urinary symptoms. The prevalence rises with age, affecting about 50% of men in their 50s and 60% of men in their 60s. Without treatment, it can lead to complications such as acute urinary retention or kidney failure, so if you have symptoms, please consult a urologist.

Cardiac Arrest

#cardiac arrest, #cardiopulmonary resuscitation, #golden time, #targeted temperature management, #automated external defibrillator

Cardiac arrest is a life-threatening emergency in which the heart stops and cannot pump blood to the body. Calling 119, prompt cardiopulmonary resuscitation (CPR) by bystanders, and treatment by an emergency medicine specialist are key to saving the patient's life.

Cerebral Aneurysm

#cerebral aneurysm, #subarachnoid hemorrhage, #headache, #cerebral blood vessels, #coil embolization, #surgical clipping, #brain hemorrhage, #MRA, #CTA, #head pain, #splitting headache, #migraine, #pain at the back of the head, #double vision, #overlapping images

A cerebral aneurysm is a condition in which the wall of a blood vessel in the brain becomes abnormally thin and bulges outward. Before it ruptures, it usually causes no symptoms and is sometimes found by chance during a health checkup. Because a rupture can become a life-threatening emergency, people with risk factors are advised to talk with their doctor about regular screening. If a health checkup shows an abnormal finding, please consult a neurosurgery specialist, and if a sudden, severe headache occurs, seek immediate medical attention at an emergency room.

Cerebral Hemorrhage

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.

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.

Croup

#croup, #barking cough, #difficulty breathing, #common cold, #airway swelling, #breath holding, #difficulty breathing, #shortness of breath, #choking sensation, #dry cough, #persistent cough, #cough that won't stop, #body swelling, #facial swelling, #leg swelling, #swelling of the hands and feet

Croup is an emergency condition in which a child suddenly has difficulty breathing. Symptoms typically worsen at night and can become life-threatening, so prompt evaluation by a pediatric specialist or emergency care is needed.

Deep Vein Thrombosis (DVT)

#deep vein thrombosis, #DVT, #blood clot, #pulmonary embolism, #leg swelling, #economy class syndrome, #dry cough, #persistent cough, #cough that won't stop

Deep vein thrombosis is a condition in which a blood clot (a lump formed when blood coagulates) develops in a deep vein of the leg and blocks the vessel. Leg swelling and pain are the main symptoms, and if the clot travels to the lungs, a dangerous complication called pulmonary embolism can occur. If you suspect symptoms, please consult a medical specialist right away.

Dizziness

#dizziness, #vertigo, #balance disorder, #cerebral infarction, #orthostatic hypotension, #headache, #splitting headache, #migraine, #pain at the back of the head, #lightheadedness, #spinning sensation, #unsteadiness, #vision going dark, #collapse, #loss of consciousness, #fainting, #weakness in the arms or legs, #difficulty moving one side of the body, #anxious feeling, #nervousness, #worrying for no reason

Dizziness is a general term for a feeling that the surroundings are spinning or that it is hard to keep your balance. It may be caused by something simple, such as anemia or an ear problem, but it can also be a sign of a dangerous brain condition. Because the exact cause must be found and treated, please be sure to consult a medical specialist for an examination.

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.

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.

Hip Fracture

#hip fracture, #fall, #femur, #hip bone fracture, #joint replacement, #fracture fixation, #osteoporosis, #fracture in older adults

A hip fracture is the most serious type of fracture that occurs after a fall. The hip joint is the joint where the pelvic bone and the thigh bone (femur) connect. After a fracture, a person cannot bear weight or stand, which makes walking independently difficult, and in older patients it can lead to complications such as pneumonia, pressure sores, and sepsis, so mortality is high. If you have pain in the hip or upper thigh after a fall, please consult an orthopedic specialist right away.
