Orthostatic hypotension is a condition in which blood pressure drops sharply when a person suddenly stands up from sitting or lying down, causing dizziness, fainting, and other symptoms. It can also occur in people with high blood pressure. Some studies link it to an increased risk of dementia, so if symptoms recur, please consult a medical specialist.

Osteoporosis

#osteoporosis, #bone density, #compression fracture, #menopause, #calcium, #vitamin D, #bisphosphonates, #fall prevention, #vertebral fracture, #femoral fracture, #dry cough, #persistent cough, #cough that won't stop

Osteoporosis is a condition in which bones become weaker and can break easily even from a minor impact. There are often no symptoms, and it is frequently discovered only after a fracture occurs. The risk is higher in postmenopausal women and older adults, so regular bone density testing and preventive lifestyle habits are important. Please be sure to discuss treatment options with a medical specialist.

Prostate Disorders

#benign prostatic hyperplasia, #prostate cancer, #PSA, #difficulty urinating, #sense of incomplete bladder emptying, #nocturia, #hematuria, #acute urinary retention, #kidney failure, #men's health, #urinating frequently, #frequent trips to the bathroom, #blood in urine, #red urine, #bloody urine

Prostate disorders include benign prostatic hyperplasia, which causes difficulty urinating, and prostate cancer, which is increasing rapidly among men. Both conditions tend to have few or mild symptoms in their early stages, making them easy to overlook, but if left unaddressed, they can lead to serious complications such as urinary retention or kidney failure. If you have any urinary symptoms, please be sure to consult a medical specialist.

Schizophrenia

Schizophrenia is a major mental illness in which the ability to distinguish reality from one's own thoughts and perceptions is impaired. In Korean, the disorder was previously called jeongsinbunyeolbyeong (literally, "split-mind disease") but was renamed johyeonbyeong in 2011; the new term means "tuning the strings," reflecting the idea that mental confusion arises when the brain's neural signaling is not properly tuned. With appropriate treatment and management, people with schizophrenia can maintain daily functioning.
