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.

Cerebrovascular Disease (Stroke)

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.

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.

Hypotension (Low Blood Pressure)

#hypotension, #orthostatic hypotension, #essential hypotension, #dizziness, #blood pressure, #shock, #headache, #a splitting headache, #migraine, #back-of-head pain, #feeling dizzy, #spinning sensation, #unsteadiness, #feeling faint, #lack of energy, #fatigue, #feeling tired all the time, #loose stool, #watery diarrhea, #frequent trips to the bathroom

Hypotension refers to blood pressure that is lower than normal. Some people have chronically low blood pressure, but when blood pressure that was normal or high suddenly drops, it can lead to serious consequences within a short time. If you experience a sudden drop in blood pressure, please seek prompt evaluation by a medical specialist.

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.

Orthostatic Hypotension

#orthostatic hypotension, #dizziness, #syncope, #autonomic nervous system, #blood pressure, #lightheadedness, #headache, #a splitting headache, #migraine, #back-of-head pain, #feeling dizzy, #spinning sensation, #unsteadiness, #feeling faint, #collapsing, #loss of consciousness, #passing out, #fainting, #lack of energy, #listlessness, #feeling tired all the time

Orthostatic hypotension is a condition in which blood pressure drops sharply when a person suddenly stands up from sitting or lying down, causing dizziness, fainting, and other symptoms. It can also occur in people with high blood pressure. Some studies link it to an increased risk of dementia, so if symptoms recur, please consult a medical specialist.

Tachycardia

Tachycardia is a condition in which the heart beats abnormally fast, and it may cause dizziness or fainting. If symptoms occur, please consult a cardiology specialist so that the condition can be managed safely.

Vestibular Neuritis

#vestibular neuritis, #dizziness, #viral infection, #nystagmus, #vomiting, #feeling dizzy, #spinning sensation, #unsteadiness, #feeling faint

Vestibular neuritis is a condition in which inflammation of the vestibular nerve, located in the inner ear, causes severe spinning vertigo. If severe dizziness and vomiting continue for several days without relief, please visit a hospital for evaluation and medication from a medical specialist.
