Fatigue is a state in which the whole body feels weak, or tasks that are usually easy feel exhausting. It is classified as acute if it lasts less than 1 month and chronic if it lasts 3 months or longer. The causes of fatigue are very diverse, so if fatigue lasts 1 to 2 weeks or longer despite enough rest, please consult a medical specialist.

Biological Age and Health Age

#biological age, #health age, #physiological age, #aging, #health checkup, #lifestyle habits, #metabolism, #health risk assessment

Biological age is an estimate of the degree of aging, expressed as a number, based on health indicators such as blood pressure, blood glucose, and liver function. Health age is an age that reflects health risk factors such as lifestyle habits and family history. Neither measure is a definitive diagnostic tool, but both can be used to motivate people to adopt healthier lifestyle habits.

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.

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.

Meniere's disease is a condition in which excess endolymph builds up in the inner ear, raising the pressure and causing repeated episodes of dizziness, hearing loss, tinnitus, and a feeling of fullness in the ear. The inner ear is the innermost part of the ear and consists of the cochlea, which is responsible for hearing, and the vestibular organ, which is responsible for balance. If left untreated, hearing and vestibular function may worsen permanently. Please consult an otolaryngology (ENT) specialist.
