Cerebral Aneurysm

A cerebral aneurysm is a condition in which the wall of a blood vessel in the brain becomes abnormally thin and bulges outward. Before it ruptures, it usually causes no symptoms and is sometimes found by chance during a health checkup. Because a rupture can become a life-threatening emergency, people with risk factors are advised to talk with their doctor about regular screening. If a health checkup shows an abnormal finding, please consult a neurosurgery specialist, and if a sudden, severe headache occurs, seek immediate medical attention at an emergency room.2026-06-26

Cerebrovascular disease (stroke) is a condition in which a blood vessel in the brain becomes blocked or ruptures, causing brain damage. To minimize aftereffects, prompt emergency response is most important, under the principle that 'time is brain.' The risk of stroke is especially high in winter and during seasonal changes, so please follow the prevention guidelines carefully.2026-06-26

Antidepressants, cognitive behavioral therapy, and graded exercise therapy have been reported to be helpful. Please consult a medical specialist before deciding on the direction of treatment.2026-06-26

#chronic kidney disease, #chronic renal failure, #kidney, #renal, #proteinuria, #glomerular filtration rate, #diabetic nephropathy, #lack of energy, #listlessness, #persistent tiredness, #body swelling, #facial swelling, #leg swelling, #swollen hands and feet
Chronic kidney disease (CKD) is a condition in which abnormalities in kidney function or structure persist for 3 months or longer. In the early stages there are often no particular symptoms, so the disease may go unnoticed and be discovered only after it has progressed considerably. People who have diabetes or high blood pressure, or who have a family history of kidney disease, need regular testing. If a health checkup reveals a kidney abnormality, please consult a medical specialist to confirm it.2026-06-26

#COPD, #chronic obstructive pulmonary disease, #airway obstruction, #smoking, #pulmonary function test, #bronchodilator, #smoking cessation, #emphysema, #dry cough, #persistent minor cough, #cough that will not stop
Chronic obstructive pulmonary disease (COPD) is a chronic lung disease in which the airways (the passages through which air travels) gradually narrow, making breathing difficult. The leading cause is smoking. Airways that have narrowed are mostly not restored, so early detection and smoking cessation are especially important. If cough, sputum, or shortness of breath persists, please consult a pulmonology and allergy specialist.2026-06-26

Chronic Osteomyelitis
#chronic osteomyelitis, #osteomyelitis, #open fracture, #shinbone, #tibia, #bone infection, #flap surgery, #multidisciplinary care, #seeing double, #overlapping images
Chronic osteomyelitis is a condition in which bone is infected by bacteria and inflammation persists for a long time. It most often occurs after an open fracture (a fracture in which the bone is exposed to the outside). It is difficult to treat and often recurs, so care at a specialized medical institution is important.2026-06-26
