Basal cell carcinoma is the most common skin cancer. It mainly occurs in areas with long-term ultraviolet exposure, and the outlook is generally favorable when it is completely removed by surgery. If you have an area of skin that has not healed for a long time or keeps changing, please be sure to consult a dermatologist.

Heat Waves and Heart Health

#heat wave, #sudden cardiac death, #heat stroke, #heat-related illness, #heart attack, #angina, #cardiac arrest, #arrhythmia, #hydration, #summer health, #dizziness, #feeling faint, #unsteadiness, #vision going dark, #fainting, #loss of consciousness, #syncope, #breath holding, #difficulty breathing, #shortness of breath, #choking sensation

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.

If hypothermia is suspected, please call 119 immediately or go to a hospital.

Stroke

#stroke, #dementia, #vascular dementia, #high blood pressure, #snoring, #weakness in the arms or legs, #difficulty moving one side of the body

Stroke is a medical emergency that occurs when a blood vessel in the brain becomes blocked or ruptures. A blocked blood vessel is called a cerebral infarction, and a ruptured one is called a cerebral hemorrhage. If symptoms appear, going to the emergency room immediately is the most important way to reduce aftereffects. Stroke is also closely related to dementia. The main symptom of stroke is the loss of a specific bodily function, such as paralysis of the arms or legs. The most important factor in treatment is the golden time (the critical time window for treatment), so please be sure to consult a medical specialist for an accurate diagnosis. If abnormal symptoms appear, call 119 (Korea's emergency number) or go to the emergency room immediately.
