Air-conditioning sickness is a general term for the various physical symptoms that appear when air conditioners or other cooling devices are overused and the temperature difference between indoors and outdoors becomes large. It is not an officially defined medical diagnosis, but headache, fatigue, and digestive problems may occur. In most cases, symptoms may improve within a few days if use of cooling devices is reduced. 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

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.

Growth hormone is a hormone secreted by the pituitary gland that is responsible for growth and metabolic function. Growth hormone therapy may be considered when short stature is caused by growth hormone deficiency or certain genetic conditions. Treatment continues for a long period, and consultation with an experienced pediatric endocrinology specialist is needed.

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

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.

Orthostatic Hypotension

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.

Scrub typhus is an acute febrile infectious disease that occurs mainly in the fall. It is caused by the bite of a chigger mite larva carrying the bacterium Orientia tsutsugamushi. Covering the skin well during outdoor activity and showering afterward are key to prevention. If flu-like symptoms develop after outdoor activity in the fall, please consult a medical specialist.

Secondhand smoke exposure, also called passive smoking, means that a person who does not smoke breathes in smoke from a smoker's cigarette. Tobacco smoke contains thousands of chemicals, including carcinogens (substances that can cause cancer), and long exposure in an enclosed space can be harmful even to nonsmokers. If you are concerned about secondhand smoke, please consult a medical specialist.

Sleep apnea is a condition in which breathing repeatedly stops or becomes markedly reduced for 10 seconds or longer during sleep. If left untreated, it can worsen various systemic conditions such as high blood pressure, heart disease, stroke, and diabetes mellitus. It is not a simple sleeping habit but a condition that may require treatment. If you snore heavily or feel severe daytime sleepiness, please consult an ENT specialist.

Snoring is a sound produced when the airway in the throat narrows during sleep. Although it may seem like a simple sleep habit, it can progress to sleep apnea. Sleep apnea is associated with various systemic conditions, including high blood pressure, heart disease, and stroke. If snoring is severe or accompanied by apnea, please consult an otolaryngology (ear, nose, and throat) specialist.

Tension-Type Headache

#tension-type headache, #head pain, #forward head posture, #posture correction, #trigger point injection, #rehabilitation therapy, #stress, #headache, #splitting headache, #migraine, #pain at the back of the head

Tension-type headache is a very common headache that is caused not by the nerve tissue of the brain itself but by sustained contraction of the muscles that surround the skull and the back of the neck. Stress, poor posture, and lack of sleep are the main causes. If headaches persist or worsen, please consult a medical specialist.
