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.

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.

Hip Fracture

#hip fracture, #fall, #femur, #hip bone fracture, #joint replacement, #fracture fixation, #osteoporosis, #fracture in older adults

A hip fracture is the most serious type of fracture that occurs after a fall. The hip joint is the joint where the pelvic bone and the thigh bone (femur) connect. After a fracture, a person cannot bear weight or stand, which makes walking independently difficult, and in older patients it can lead to complications such as pneumonia, pressure sores, and sepsis, so mortality is high. If you have pain in the hip or upper thigh after a fall, please consult an orthopedic specialist right away.

Hypertension and Diet Management

#hypertension, #blood pressure, #blood pressure medication, #sodium, #hyperlipidemia, #diabetes mellitus, #heart

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.

If an abnormal finding is detected or you have any concerns, please be sure to consult a medical specialist.

Kidney Transplant Process

#kidney transplantation, #kidney transplant, #living-donor kidney transplantation, #deceased-donor kidney transplantation, #immunosuppressants, #rejection, #end-stage kidney failure, #KONOS, #organ transplantation, #double vision, #overlapping images

Kidney transplantation is a surgery that transplants a healthy kidney into the body to replace a kidney that has lost its function. Unlike dialysis, it can restore most of the kidney's various functions (removing waste products, regulating electrolytes, secreting hormones that stimulate blood cell production, and others), which makes it one of the main treatment options for end-stage kidney failure. Whether and how to have a transplant depends on each patient's health condition, so please be sure to decide through consultation with a medical specialist.

Liver cancer is a malignant tumor that develops in the liver, which is responsible for detoxification and nutrition in the body. The liver is called the 'silent organ' because there is no particular pain even when the disease becomes advanced. By the time symptoms appear, the disease has often already progressed considerably, so please do not judge on your own; be sure to have regular checkups and consult a medical specialist.

Malocclusion and Orthodontic Treatment

#malocclusion, #orthodontics, #orthodontic treatment, #open bite, #deep bite, #anterior crossbite, #clear aligners, #brackets, #tooth alignment

Malocclusion is a condition in which the upper and lower teeth do not fit together correctly. When the teeth fit together well, it is easier to chew food effectively, speak clearly, and maintain a natural appearance. Leaving malocclusion untreated may reduce chewing efficiency and make tooth decay and gum disease more likely, so an accurate diagnosis and treatment at an appropriate time are important. Please consult an orthodontic specialist to decide whether and when to begin orthodontic treatment.
