Arrhythmia

#arrhythmia, #atrial fibrillation, #bradycardia, #tachycardia, #pacemaker, #ventricular fibrillation, #stroke, #anticoagulants, #dizziness, #spinning sensation, #unsteadiness, #vision going dark, #collapse, #loss of consciousness, #fainting, #lack of energy, #lethargy, #persistent fatigue, #rapid heartbeat, #pounding heart, #fast pulse

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.

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.

Blood Cancer

#blood cancer, #leukemia, #multiple myeloma, #platelets, #bone marrow, #anemia, #chemotherapy, #hematopoietic stem cell transplantation

Blood cancer refers to cancer that arises in the bone marrow, the organ responsible for producing blood cells. The bone marrow makes three types of blood cells: white blood cells, red blood cells, and platelets. When the bone marrow malfunctions, abnormalities in the number, shape, or function of these cells can cause a variety of symptoms. Frequent nosebleeds or easy bruising can occur, but these symptoms do not necessarily mean a person has blood cancer. If abnormal results appear on a blood test, please consult a hematology-oncology specialist.

Breast Cancer Surgery and Breast Reconstruction

#breast cancer, #breast reconstruction, #robotic surgery, #breast implant, #surgery

Breast cancer is a common cancer in women. Surgical techniques have advanced considerably, making both treatment and reconstruction of the shape of the breast possible. Please do not try to judge a condition from encyclopedia information; be sure to consult a surgery specialist for an examination.

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.

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.

Esophageal Cancer

#esophageal cancer, #esophagus, #Barrett's esophagus, #esophagectomy, #chemotherapy, #radiation, #alcohol abstinence, #smoking cessation, #esophageal cancer prevention

Esophageal cancer is a malignant tumor that develops in the esophagus. It can be difficult to detect in the early stages, and the earlier it is found, the better the treatment outcomes tend to be. Reducing risk factors and getting regular screening are important, and if you have any unusual symptoms, please consult a medical specialist.

Gallbladder Cancer

#gallbladder cancer, #bile duct cancer, #gallbladder, #gallstones, #cholecystitis, #abdominal ultrasound, #jaundice, #laparoscopy, #stomachache, #tummy ache, #bellyache, #pain inside the abdomen, #feeling of indigestion (food stuck), #bloated feeling in the stomach, #poor digestion

The gallbladder is a small pouch that temporarily stores the digestive fluid (bile) made in the liver. Gallbladder cancer, a malignant tumor that develops there, causes no obvious symptoms until the disease is quite advanced, which makes early detection very difficult. If you have persistent indigestion or abdominal pain, please do not dismiss it on your own; be sure to consult a medical specialist for an examination and detailed tests.

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.

Heart Murmur

#heart murmur, #pediatric cardiology, #echocardiogram, #congenital heart disease

A heart murmur is an extra whooshing sound heard in addition to the normal heart sounds. It is commonly detected at infant and toddler checkups and is usually a normal finding, but it can be a sign of a heart defect, so evaluation by a pediatric cardiologist is needed.

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.

Hepatobiliary and Pancreatic Cancer

#liver cancer, #bile duct cancer, #pancreatic cancer, #hepatobiliary and pancreatic surgery, #chemotherapy

Hepatobiliary and pancreatic cancer often has no symptoms in the early stage and is frequently found when surgery is already difficult. However, with advances in medical technology, surgery may become possible after chemotherapy in some cases, so please consult a hepatobiliary and pancreatic surgery 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.

Leukemia is a malignant tumor that arises from immature blood cells in the bone marrow. It is classified as acute or chronic, and as myeloid or lymphoid depending on the type of cell involved. Unlike in the past, advances in medicine, including targeted therapy, have expanded the treatment options. Please discuss the diagnosis and treatment plan thoroughly with a hematology-oncology specialist.
