Diabetic Retinopathy

#Diabetic retinopathy, #Macular edema, #Retina, #Neovascularization, #Vitreous hemorrhage, #Retinal detachment, #Diabetes complications, #Fundus exam, #OCT, #Vision loss, #Blindness, #Body swelling, #Face swelling, #Leg swelling, #Swollen hands and feet, #Blurry eyes, #Trouble seeing, #Blurred vision

Diabetic retinopathy is a condition in which prolonged high blood sugar damages the tiny blood vessels and nerve tissue of the retina, the light-sensing layer inside the eye. About 15 to 30% of diabetic patients in Korea have this condition, and it is important to have an annual eye exam even without symptoms. Diabetic retinopathy is one of the three leading causes of blindness in Korea, so early detection and appropriate treatment are essential to protecting your vision.

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.

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.

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.

Forgetfulness and Dementia

#forgetfulness, #dementia, #mild cognitive impairment, #memory, #brain cells, #stress, #trouble falling asleep, #frequent waking, #poor sleep quality

It can be difficult to tell whether forgetfulness is simple age-related forgetfulness or a sign of dementia. Forgetfulness is a normal experience, but dementia is a brain disease. Rather than judging this on your own, please consult a medical specialist if you notice any concerning symptoms.

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.

Growth hormone is a hormone secreted by the pituitary gland that is responsible for growth and metabolic function. Growth hormone therapy may be considered when short stature is caused by growth hormone deficiency or certain genetic conditions. Treatment continues for a long period, and consultation with an experienced pediatric endocrinology specialist is needed.

Headache is a common symptom that almost anyone can experience, but it can also be a sign of a brain condition or a nervous system problem. If you find yourself relying too heavily on pain relievers to get rid of headaches, or if headaches are interfering with daily life, please don't try to judge the cause yourself — see a medical specialist.

Hearing Loss

#hearing loss, #hearing, #hearing aid, #cochlear implant, #bone conduction hearing aid, #auditory rehabilitation, #sensorineural hearing loss, #conductive hearing loss, #ringing in the ears, #noise in the ear, #cannot hear, #difficulty hearing sounds

Hearing loss refers to a condition in which hearing is reduced and it is hard to hear sounds properly. It has many causes, including aging, noise, and otitis media. According to data from the Health Insurance Review and Assessment Service, the number of patients with hearing loss has been steadily increasing. If you feel your hearing is declining, please do not put it down to age; consult an otolaryngology (ENT) specialist to have the exact cause diagnosed.

Hearing loss is not just a symptom of difficulty hearing sounds; it affects overall quality of life, including withdrawal from relationships, depression, and cognitive decline. In recent years, bone conduction hearing aid implantation, which delivers sound through the bone, has been used for patients who have difficulty using conventional hearing aids. If your hearing declines, please do not leave it untreated by blaming 'age'; consult a medical specialist.

Hoarding Disorder

Hoarding disorder is a mental health condition characterized by a compulsive inability to discard items regardless of their actual value or usefulness. Living spaces can become so filled with belongings that they are no longer usable, raising hygiene concerns and the risk of accidents. Depression or anxiety disorders often occur alongside hoarding disorder. If symptoms are suspected, please consult a psychiatrist.

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.

Hypertension is a condition in which blood pressure stays persistently high. Blood pressure is the force exerted on the walls of the blood vessels when the heart pumps out blood. Hypertension often causes no symptoms, so it is also called the "silent killer." If left untreated, it can lead to complications in the heart, brain, and kidneys, so evaluation by a medical specialist and steady management are needed.

An implantable bone conduction hearing aid is a surgical option that can restore hearing for people who have difficulty using a regular hearing aid. A detailed hearing evaluation by an ENT specialist is essential to determine whether this surgery is appropriate.
