If symptoms are severe or accompanied by a high fever, please consult a medical specialist.

Benign Prostatic Hyperplasia (BPH)

#benign prostatic hyperplasia, #prostate, #lower urinary tract symptoms, #frequent urination, #nocturia, #urinary urgency, #sense of incomplete bladder emptying, #acute urinary retention, #alpha-blocker, #transurethral resection of the prostate, #headache, #a splitting headache, #migraine, #back-of-head pain, #urinating frequently, #frequent trips to the bathroom, #blood in urine, #red urine, #bloody urine

Benign prostatic hyperplasia (BPH) is a very common condition in men in which the prostate enlarges with age, narrowing the urethra and causing urinary symptoms. The prevalence rises with age, affecting about 50% of men in their 50s and 60% of men in their 60s. Without treatment, it can lead to complications such as acute urinary retention or kidney failure, so if you have symptoms, please consult a urologist.

Cerebral Aneurysm

#cerebral aneurysm, #subarachnoid hemorrhage, #headache, #cerebral blood vessels, #coil embolization, #surgical clipping, #brain hemorrhage, #MRA, #CTA, #head pain, #splitting headache, #migraine, #pain at the back of the head, #double vision, #overlapping images

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.

Cerebral hemorrhage is a medical emergency in which a blood vessel in the brain ruptures and bleeding occurs. Blood pressure management is the most important way to prevent it, and if symptoms occur, you should go to the emergency room immediately.

Cerebrovascular Disease (Stroke)

#stroke, #cerebral infarction, #cerebral hemorrhage, #thrombolysis, #thrombectomy, #cerebrovascular disease, #winter stroke, #first aid, #post-stroke sequelae, #multidisciplinary care, #headache, #splitting headache, #migraine, #pain at the back of the head, #lightheadedness, #spinning sensation, #unsteadiness, #vision going dark, #weakness in the arms or legs, #difficulty moving one side of the body

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.

Chronic fatigue syndrome is a condition in which severe fatigue persists for 3 months or longer even with adequate rest. Because there are many hypotheses about its cause, treatment is tailored to each individual. 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.

Because the exact cause must be found and treated, please be sure to consult a medical specialist for an examination.

Glaucoma

Glaucoma is a disease in which the optic nerve inside the eye is gradually damaged by high intraocular pressure or other factors, causing the visual field to narrow progressively. There are almost no symptoms in the early stage, so detection can be delayed, and rather than a cure, lifelong consistent management is important. Detecting it early through regular checkups and starting treatment is the best way to help prevent blindness.

Repeatedly holding urine or stool for long periods may cause various problems in bladder, urinary tract, and digestive health. If you often have to hold urine or stool, please consult a medical specialist.

It can cause headache, dizziness, muscle cramps, and, in severe cases, decreased consciousness. People who work outdoors, older adults, and children need to take particular care. If symptoms appear, move to a cool place immediately, and if heat stroke is suspected, call 119 (Korea's emergency number) right away. Please consult a medical specialist.

Hypertension (High Blood Pressure)

#hypertension, #blood pressure, #blood pressure medication, #sodium, #arteriosclerosis, #antihypertensive drugs, #essential hypertension, #headache, #a splitting headache, #migraine, #back-of-head pain

Hypertension is a condition in which blood pressure, the force exerted on the walls of the blood vessels when the heart pumps out blood, stays persistently high; it is classified as a systolic blood pressure of 140 mmHg or higher or a diastolic blood pressure of 90 mmHg or higher. Hypertension often causes no symptoms, so it is called the "silent killer." If left untreated, it can lead to serious complications such as stroke, heart disease, and kidney disease, so evaluation by a medical specialist and steady management are needed.

Hypotension (Low Blood Pressure)

#hypotension, #orthostatic hypotension, #essential hypotension, #dizziness, #blood pressure, #shock, #headache, #a splitting headache, #migraine, #back-of-head pain, #feeling dizzy, #spinning sensation, #unsteadiness, #feeling faint, #lack of energy, #fatigue, #feeling tired all the time, #loose stool, #watery diarrhea, #frequent trips to the bathroom

Hypotension refers to blood pressure that is lower than normal. Some people have chronically low blood pressure, but when blood pressure that was normal or high suddenly drops, it can lead to serious consequences within a short time. If you experience a sudden drop in blood pressure, please seek prompt evaluation by a medical specialist.

Kidney cancer is a malignant tumor that develops in the kidney. There are almost no symptoms in the early stages, so it is difficult to notice on your own, and in most cases it is found incidentally during a health checkup. Even without symptoms, it is important to detect it early through regular health checkups. If an abnormal finding is detected or you have any concerns, please be sure to consult a medical specialist.
