Acute Cerebral Infarction (Ischemic Stroke)

#cerebral infarction, #acute cerebral infarction, #blood clot, #thrombectomy, #FAST

Acute cerebral infarction is a very urgent condition in which a blocked blood vessel in the brain damages brain cells. Time is critical, and rapid recognition and emergency treatment are most important, so please seek immediate medical attention.

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.

Arrhythmia

An arrhythmia is a condition in which the heartbeat is abnormally slow, fast, or irregular. The heart beats about 100,000 times a day to supply blood to the whole body, and when there is a problem with this rhythm, various symptoms may occur. The types and causes of arrhythmia vary, so if you have symptoms, be sure to consult a medical specialist.

Cerebral Aneurysm

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.

Coronary Artery Disease (Angina and Myocardial Infarction)

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.

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.

Dental Implant

#dental implant, #tooth, #gums, #dentures, #bridge, #dentistry, #peri-implantitis, #jawbone, #osteoporosis

A dental implant is a treatment that restores tooth function by placing an artificial tooth root into the site of a missing tooth when a natural tooth can no longer be treated. It is widely used because it can address some of the drawbacks of conventional dentures or bridges. Whether implant treatment is appropriate depends on an individual's health status and jawbone condition, so please be sure to discuss this thoroughly with a dental specialist before making a decision.

Frostbite

#Frostbite, #Cold-related illness, #Chilblains, #Cold wave, #Necrosis, #Fingers, #Toes, #Winter health

Frostbite occurs when body tissue exposed to severe cold freezes. It most often affects exposed areas such as the fingers, toes, nose, and ears. In severe cases, the tissue can undergo necrosis (tissue death), which may require amputation of the affected body part. If you suspect frostbite, protect the area from refreezing and seek medical care right away.

Heat Waves and Heart Health

#heat wave, #sudden cardiac death, #heat stroke, #heat-related illness, #heart attack, #angina, #cardiac arrest, #arrhythmia, #hydration, #summer health, #dizziness, #feeling faint, #unsteadiness, #vision going dark, #fainting, #loss of consciousness, #syncope, #breath holding, #difficulty breathing, #shortness of breath, #choking sensation

Extreme heat raises the risk of angina, heart attack, and cardiac arrest by increasing heart rate, promoting blood clotting, and placing added strain on the heart. Older adults age 65 and older, people with cardiovascular disease, and those with chronic conditions such as high blood pressure or diabetes need to be especially careful. On days when a heat wave warning is issued, please stay active indoors for safety.

Hemorrhoids are swollen vascular tissue inside the anus that may bulge or protrude outside the anus. Most of what is commonly referred to as 'piles' is, in fact, hemorrhoids. If you have symptoms, please consult a medical specialist.

Liver Transplantation

Liver transplantation is an operation that replaces a liver that has lost its function with a healthy liver, and it is one of the treatment options for several serious liver diseases, such as liver failure caused by cirrhosis and liver cancer. Since it was first performed in Korea in 1988, advances in technology and medication have led to more than 1,500 transplants a year at present, and the overall surgical success rate is reported to be about 90 to 95%. Liver transplantation is an important decision for both the recipient and the donor, so please discuss it thoroughly with your treating physician before making a decision.

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.

A solid tumor is a cancer that forms a mass, as opposed to 'liquid' cancers such as blood cancers (hematologic malignancies). Most cancers are solid tumors. Management strategies for preventing complications are as follows.

Gum disease (periodontal disease), marked by bleeding and swollen gums, is not limited to the mouth — it can worsen systemic conditions such as dementia, heart disease, and diabetes. Regular visits to a periodontal specialist and routine dental scaling are essential.

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.
