#contact lenses, #soft lenses, #rigid (hard) lenses, #keratitis, #lens care, #lens cleaning, #swimming, #body swelling, #facial swelling, #leg swelling, #swelling of the hands and feet

Because contact lenses sit directly on the cornea, improper use can lead to serious eye conditions such as keratitis and dry eye disease. Proper use and hygiene are important. If any unusual symptoms occur, please see an ophthalmology specialist right away.

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 and Bone Conduction Hearing Aid Implantation

#hearing loss, #sensorineural hearing loss, #conductive hearing loss, #hearing aid, #bone conduction hearing aid, #cochlear implant, #presbycusis, #otitis media, #external auditory canal atresia, #dementia, #cognitive decline, #cannot hear, #difficulty hearing sounds

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.

Heart Failure

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.

Heart Murmur

#heart murmur, #pediatric cardiology, #echocardiogram, #congenital heart disease

A heart murmur is an extra whooshing sound heard in addition to the normal heart sounds. It is commonly detected at infant and toddler checkups and is usually a normal finding, but it can be a sign of a heart defect, so evaluation by a pediatric cardiologist is needed.

Heat Waves and Heart Health

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.

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.

Meniscus Tear

#meniscus, #meniscus tear, #knee cartilage, #knee pain, #arthroscopic surgery, #sports injury, #knee locking

A meniscus tear is a tear in the crescent-shaped cartilage (the meniscus) located between the thighbone (femur) and the shinbone (tibia) in the knee. When this happens, the meniscus may absorb shock less effectively, which can affect the health of the knee joint. If you have symptoms, please consult a medical specialist.

Noise-Induced Hearing Loss

#noise-induced hearing loss, #earphones, #tinnitus, #cochlea, #hearing damage, #noise, #hearing, #headphones, #double vision, #overlapping images, #ringing in the ear, #noise in the ear, #cannot hear, #difficulty hearing

Noise-induced hearing loss is a condition in which hearing is damaged by loud, sustained sound exposure. It once occurred mainly in industrial workplaces, but it is now increasing among teenagers and young adults as the use of personal audio devices such as earphones grows. There is currently no treatment that restores hearing once it has been damaged, so prevention is most important. If your hearing declines or you develop tinnitus, please consult an ENT specialist.

The causes of fatigue are very diverse, so if fatigue lasts 1 to 2 weeks or longer despite enough rest, please consult a medical specialist.
