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.

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.

Bladder Cancer

Bladder cancer is a malignant tumor that develops in the inner lining of the bladder. In the early stages, treatment that preserves the bladder is often possible, but in advanced cases the bladder may need to be removed. Early detection is very important for treatment outcomes. If you have suspicious symptoms such as blood in the urine, be sure to consult a medical specialist.

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.

Cardiac Arrest

#cardiac arrest, #cardiopulmonary resuscitation, #golden time, #targeted temperature management, #automated external defibrillator

Cardiac arrest is a life-threatening emergency in which the heart stops and cannot pump blood to the body. Calling 119, prompt cardiopulmonary resuscitation (CPR) by bystanders, and treatment by an emergency medicine specialist are key to saving the patient's life.

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.

Chronic Renal Failure

#kidney transplantation, #chronic renal failure, #kidney, #end-stage renal disease, #hemodialysis, #immunosuppressants

The kidneys are important organs that filter waste products from the body and remove them in the urine. When a chronic disease has damaged the kidneys completely, a new kidney may need to be transplanted to sustain life. Lifelong careful management is needed even after transplantation, so please do not rely on this Health Encyclopedia alone; receive proper management through consultation with a transplant specialist.

When blood sugar remains high over time, diabetes can lead to complications in several organs, including the eyes, kidneys, nerves, and cardiovascular system. Preventing these complications requires blood sugar control along with managing blood pressure and cholesterol/lipid levels, as well as regular complication screening. Please continue treatment consistently with your doctor.

Drug Treatment for Rheumatoid Arthritis

#rheumatoid arthritis, #antirheumatic drugs, #biologics, #JAK inhibitors, #small molecule inhibitors, #methotrexate, #targeted therapy, #immunosuppressants

Rheumatoid arthritis is a chronic disease in which the immune system attacks the body's own joints and causes inflammation. After diagnosis, drug treatment is started to reduce inflammation and slow disease progression. In recent years, in addition to conventional antirheumatic drugs, a variety of targeted therapies have come into use, including biologics and small molecule inhibitors (JAK inhibitors). Because each drug has different characteristics and side effects, please discuss treatment options thoroughly with your doctor before deciding on the approach that is right for you.

It is also known as “hamburger disease,” a name that came from cases linked to eating undercooked hamburger patties. It occurs most often in children age 5 and younger. If these symptoms are suspected, please see a medical specialist right away.
