#anorexia nervosa, #loss of appetite, #eating disorder, #underweight, #psychiatry, #constipation, #difficulty passing stool, #hard stool

Anorexia nervosa is an eating disorder in which a person restricts food intake because of an intense fear of gaining weight and insists on maintaining a body weight below the normal range. It is a serious condition that can become life-threatening, so please do not try to judge it on your own; be sure to consult a psychiatrist.

Arrhythmia

An arrhythmia is a condition in which the heartbeat is abnormally slow, fast, or irregular. The heart beats about 100,000 times a day to supply blood to the whole body, and when there is a problem with this rhythm, various symptoms may occur. The types and causes of arrhythmia vary, so if you have symptoms, be sure to consult a medical specialist.

Chronic Kidney Disease (CKD)

#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.

Fine Dust (Particulate Matter) and Health

#particulate matter, #fine particulate matter (PM2.5), #Asian dust (yellow dust), #respiratory system, #mask, #KF80, #KF94, #asthma, #air pollution, #dry cough, #minor cough, #persistent cough

Fine dust consists of tiny particles floating in the air. It directly affects the respiratory tract, including the nose, bronchi, and lungs, and can also harm the whole body, including the heart, brain, and blood vessels, through the bloodstream. Long-term exposure increases the risk of asthma, reduced lung function, and cardiovascular and cerebrovascular disease. On days when fine dust levels are high, limit outdoor activities, and people at high risk are advised to wear a health protection mask.

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.

Heart Failure

Heart failure is a condition in which the heart cannot supply as much blood as the body needs. With appropriate treatment and management, it is possible to maintain daily life, but if left untreated, symptoms such as shortness of breath and swelling can worsen. If you have risk factors such as high blood pressure, diabetes mellitus, or obesity, please see a medical specialist regularly.

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.

Hypothermia

#hypothermia, #cold-related illness, #cold wave, #body temperature, #core temperature, #frostbite, #winter health, #hand tremor, #body tremor

Hypothermia refers to a drop in core body temperature to 35°C or below. The lower the body temperature falls, the more dangerous the condition becomes, and in severe cases it can lead to cardiac arrest. It can occur with prolonged exposure to extreme cold or cold environments, and extra caution is needed when alcohol has been consumed. If hypothermia is suspected, please call 119 immediately or go to a hospital.

Low-Sodium Salt Substitutes

Reducing sodium intake is beneficial, but people with poor kidney function who use salt substitutes that provide a salty taste without medical guidance may face life-threatening risks, such as cardiac arrest. Be sure to consult a nephrologist before using them.

Syncope in Children and Adolescents

#syncope, #fainting, #adolescents, #hypotension, #orthostatic hypotension, #reflex syncope, #children, #arrhythmia, #feverish, #having a fever, #high fever, #low-grade fever, #fever, #collapsing, #loss of consciousness, #passing out, #racing heart, #pounding heart, #rapid pulse, #loose stool, #watery diarrhea, #frequent trips to the bathroom

Syncope is a temporary loss of consciousness that occurs when blood pressure drops suddenly and blood flow to the brain is briefly reduced. It is commonly called fainting. It occurs more often in adolescents and older adults, and caution is needed because injuries can occur when a person falls. Because there are many possible causes, if syncope occurs, please consult a medical specialist to identify the exact cause.

Tachycardia is a condition in which the heart beats abnormally fast, and it may cause dizziness or fainting. If symptoms occur, please consult a cardiology specialist so that the condition can be managed safely.
