An abdominal wall hernia is a condition in which the abdominal wall around a surgical incision weakens after abdominal surgery, allowing tissue from inside the abdominal cavity to push out. Early detection and surgery may allow a faster recovery. If you feel an unusual lump in the abdomen or develop sudden abdominal pain, please consult a medical specialist.

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

Angina (Angina Pectoris)

#angina, #chest pain, #myocardial infarction, #coronary artery, #atherosclerosis, #stent, #sudden death

Angina is a cardiovascular condition in which the coronary arteries — the blood vessels that supply oxygen and nutrients to the heart — become narrowed, causing a dull chest pain. Because heart disease can be a major cause of sudden death, if you feel chest discomfort that is different from what you normally experience, please do not delay in consulting a medical specialist.

Asthma is a chronic respiratory condition in which the airways (the passages through which air moves in and out of the lungs) become hypersensitive, often due to allergic reactions, and narrow, causing recurring coughing, wheezing, and shortness of breath. It is sometimes mistaken for a severe cough or cold, which can delay proper treatment. Symptoms can worsen with exposure to yellow dust, fine particulate matter, or pollen. If you have recurring coughing or shortness of breath, please consult a pulmonologist or allergist.

Atopic dermatitis is a chronic skin condition in which allergic mechanisms cause ongoing inflammation of the skin. It causes severe itching and recurring eczema, and the skin can become thick and rough (lichenification). It tends to occur when a person with a genetic predisposition is exposed to allergy triggers, and symptoms can worsen with spring pollen, house dust mites, and fine particulate matter. If symptoms persist, please consult an allergist or a dermatologist.

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.

Breast cancer is a malignant tumor that develops in breast tissue, and it is one of the more common cancers in women.

Burnout and Stress Management

#burnout, #stress, #exhaustion, #sleep, #mindfulness, #goal management, #workplace, #mental health, #lack of energy, #lethargy, #persistent fatigue

Burnout (exhaustion) is not simply a matter of fatigue or lack of willpower. It is a state in which accumulated chronic stress is thought to reduce the brain's ability to regulate itself. Rather than simply 'enduring' it, management aimed at helping the brain recover is needed. It is important to recognize the early signs of burnout and find your own ways to manage stress.
