Alcoholism (Alcohol Use Disorder)

#alcoholism, #alcohol use disorder, #drinking, #alcohol abstinence, #detoxification treatment, #sobriety, #relapse prevention, #craving, #hand tremor, #body tremor, #anxious feeling, #nervousness, #worrying for no reason

Alcoholism (alcohol use disorder) is a chronic mental health condition in which drinking beyond socially accepted levels impairs physical, psychological, and social functioning. It results from a loss of the brain's control over drinking, not from a lack of willpower. Recovery may be possible with professional treatment, so please do not hesitate to ask for help.

Biological Age and Health Age

#biological age, #health age, #physiological age, #aging, #health checkup, #lifestyle habits, #metabolism, #health risk assessment

Biological age is an estimate of the degree of aging, expressed as a number, based on health indicators such as blood pressure, blood glucose, and liver function. Health age is an age that reflects health risk factors such as lifestyle habits and family history. Neither measure is a definitive diagnostic tool, but both can be used to motivate people to adopt healthier lifestyle habits.

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 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)

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.

Chronic Renal Failure

#kidney transplantation, #chronic renal failure, #kidney, #end-stage renal disease, #hemodialysis, #immunosuppressants

The kidneys are important organs that filter waste products from the body and remove them in the urine. When a chronic disease has damaged the kidneys completely, a new kidney may need to be transplanted to sustain life. Lifelong careful management is needed even after transplantation, so please do not rely on this Health Encyclopedia alone; receive proper management through consultation with a transplant specialist.

Dementia Prevention

#dementia prevention, #three do's and three don'ts, #depression, #stress, #aerobic exercise

Dementia does not appear suddenly; it results from harmful changes that accumulate in the brain over a long period of time. Building good habits in daily life from a young age is the best way to help prevent it. Making an ongoing effort to protect one's own health is especially important. If you or a loved one notices signs of memory loss or other cognitive changes, please consult a medical specialist.

Early-Onset Dementia (Young-Onset Dementia)

#early-onset dementia, #young-onset dementia, #alcohol-related dementia, #lifestyle diseases, #vascular dementia

Dementia is not a disease that affects only older adults. Dementia that develops at a relatively young age, between 45 and 65, is called early-onset (presenile) dementia. Because it tends to progress faster than dementia in older adults, please consult a medical specialist without delay if symptoms occur.

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.

Esophageal Cancer

#esophageal cancer, #esophagus, #Barrett's esophagus, #esophagectomy, #chemotherapy, #radiation, #alcohol abstinence, #smoking cessation, #esophageal cancer prevention

Esophageal cancer is a malignant tumor that develops in the esophagus. It can be difficult to detect in the early stages, and the earlier it is found, the better the treatment outcomes tend to be. Reducing risk factors and getting regular screening are important, and if you have any unusual symptoms, please consult a medical specialist.

The esophagus is a tube about 25 cm long that carries food from the mouth to the stomach. Reflux esophagitis and esophageal cancer are the main esophageal diseases. If you have symptoms such as heartburn, acid regurgitation (a sour taste rising into the throat), or a feeling that food is getting stuck, please consult a medical specialist.

Fluid Intake and Health

#fluid intake, #water, #empty stomach, #bowel movement, #dehydration, #health drinks, #digestion

The body keeps its fluid balance by triggering thirst when fluid is low and excreting excess fluid in the urine. Rather than following a fixed standard, the basic principle is to drink enough when you feel thirsty. Drinking water on an empty stomach in the morning can replace fluid used up overnight and may help bowel movement.

Gastritis is inflammation of the stomach's mucosa (lining). It is often found on endoscopy even without symptoms. If left unmanaged, it can progress through atrophic gastritis and intestinal metaplasia toward stomach cancer, so regular screening and lifestyle management are important.

Glaucoma

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.
