Arrhythmia

#arrhythmia, #atrial fibrillation, #bradycardia, #tachycardia, #pacemaker, #ventricular fibrillation, #stroke, #anticoagulants, #dizziness, #spinning sensation, #unsteadiness, #vision going dark, #collapse, #loss of consciousness, #fainting, #lack of energy, #lethargy, #persistent fatigue, #rapid heartbeat, #pounding heart, #fast pulse

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.

Benign Paroxysmal Positional Vertigo (BPPV)

#benign paroxysmal positional vertigo, #BPPV, #dizziness, #vertigo, #vestibular system, #semicircular canals, #canalith repositioning, #ear, #balance, #feeling dizzy, #spinning sensation, #unsteadiness, #feeling faint, #nausea, #feeling like vomiting, #vomiting, #ringing in the ear, #tinnitus, #hearing loss, #difficulty hearing

Benign paroxysmal positional vertigo (BPPV) occurs when tiny particles called otoconia become dislodged from the balance organ of the inner ear (the vestibular system) and enter the semicircular canals. Otoconia are small crystals made of calcium carbonate, sometimes described as "ear stones." The main symptom is a spinning sensation that occurs with changes in head position. If you experience dizziness, please consult an ENT specialist.

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.

Epilepsy

#epilepsy, #ganjil (former Korean name), #convulsion, #seizure, #antiepileptic drugs, #neurology, #convulsive seizure

Epilepsy is a condition in which seizures occur repeatedly because of abnormal electrical signals in the brain. In Korean it used to be called 'ganjil,' but the name was changed to 'noejeonjeung' in 2012. Epilepsy is not a single disease but a group of conditions that arise from various causes. If you suspect symptoms, please be sure to consult a neurology specialist.

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.

Heart Failure

#heart failure, #dyspnea, #edema, #heart, #obesity, #high blood pressure, #myocardial infarction, #heart medication, #heart failure prevention, #breathlessness, #difficulty breathing, #labored breathing, #feeling of suffocation, #body swelling, #facial swelling, #leg swelling, #swelling in hands and feet

Heart failure is a condition in which the heart cannot supply as much blood as the body needs. With appropriate treatment and management, it is possible to maintain daily life, but if left untreated, symptoms such as shortness of breath and swelling can worsen. If you have risk factors such as high blood pressure, diabetes mellitus, or obesity, please see a medical specialist regularly.

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.

Heat-related illness is an acute emergency condition that occurs after prolonged exposure to a hot environment. It can cause headache, dizziness, muscle cramps, and, in severe cases, decreased consciousness. People who work outdoors, older adults, and children need to take particular care. If symptoms appear, move to a cool place immediately, and if heat stroke is suspected, call 119 (Korea's emergency number) right away. Please consult a medical specialist.

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.

Meniere's Disease

#Meniere's disease, #dizziness, #hearing loss, #tinnitus, #inner ear, #vestibular organ, #endolymph, #aural fullness, #lightheadedness, #spinning sensation, #unsteadiness, #vision going dark, #nausea, #feeling about to vomit, #vomiting, #blurry vision, #difficulty seeing, #hazy vision, #ringing in the ears, #noise in the ear, #cannot hear, #difficulty hearing sounds

Meniere's disease is a condition in which excess endolymph builds up in the inner ear, raising the pressure and causing repeated episodes of dizziness, hearing loss, tinnitus, and a feeling of fullness in the ear. The inner ear is the innermost part of the ear and consists of the cochlea, which is responsible for hearing, and the vestibular organ, which is responsible for balance. If left untreated, hearing and vestibular function may worsen permanently. Please consult an otolaryngology (ENT) specialist.
