Prostate Disorders

#benign prostatic hyperplasia, #prostate cancer, #PSA, #difficulty urinating, #sense of incomplete bladder emptying, #nocturia, #hematuria, #acute urinary retention, #kidney failure, #men's health, #urinating frequently, #frequent trips to the bathroom, #blood in urine, #red urine, #bloody urine

Prostate disorders include benign prostatic hyperplasia, which causes difficulty urinating, and prostate cancer, which is increasing rapidly among men. Both conditions tend to have few or mild symptoms in their early stages, making them easy to overlook, but if left unaddressed, they can lead to serious complications such as urinary retention or kidney failure. If you have any urinary symptoms, please be sure to consult a medical specialist.

Spine Surgery

#spine surgery, #disc, #spinal stenosis, #disc herniation, #scoliosis, #spondylolisthesis, #spinal rehabilitation, #osteoporosis, #lumbar spine, #cervical spine, #body swelling, #facial swelling, #leg swelling, #swollen hands and feet, #numbness in hands and feet, #arm numbness, #tingling leg, #weakness in the arms or legs, #difficulty moving one side of the body

Spinal conditions cause a variety of symptoms, including neck and back pain, numbness in the arms and legs, and gait disturbance. Typical conditions include herniated disc (disc herniation), spinal stenosis, and spondylolisthesis. Most spinal conditions are not life-threatening, so the principle is to start with conservative treatment such as drug therapy and physical therapy, and whether and when surgery is needed depends on each patient's condition. Please consult a medical specialist for an accurate diagnosis and direction of treatment.

Stomach Cancer

#Stomach cancer, #Upper endoscopy, #Indigestion, #Heartburn, #Gastritis, #Reflux esophagitis (GERD), #Functional gastrointestinal disorder, #Endoscopic resection, #Regular checkup, #Stomach pain, #My stomach hurts, #Stomachache, #Abdominal pain, #Food feels stuck, #Bloating, #Trouble digesting, #Burning stomach, #Stomach burning, #Acid regurgitation

Stomach cancer is a malignant tumor that develops in the stomach. A malignant tumor is an abnormal mass of cells that harms the body. It is common in Korea, with about 30,000 people diagnosed each year. In its early stages, it often causes no symptoms, which makes it hard to detect early. Regular upper endoscopy is very important for early detection. If you notice unusual symptoms or have concerns, please be sure to see a medical specialist.

Structure and Function of the Brain

#brain, #cerebrum, #cerebellum, #brainstem, #frontal lobe, #hippocampus, #neuroplasticity, #neuron, #dry cough, #persistent minor cough, #cough that will not stop

The brain is the most important organ in the body. It processes all sensory information, regulates bodily functions, and is responsible for mental activities such as memory, thinking, and emotion. It is broadly divided into the cerebrum, cerebellum, and brainstem, and each part has a specific role.

Structure and Function of the Kidneys

#kidney, #renal, #glomerulus, #renal tubule, #erythropoietin, #renin, #water balance regulation, #salt balance regulation, #body swelling, #facial swelling, #leg swelling, #swelling of the hands and feet

The kidneys are vital organs that filter the blood and remove waste products through urine. Beyond waste removal, the kidneys perform a range of functions, including regulating water and salt balance, controlling blood pressure, and stimulating red blood cell production. Understanding the structure and function of the kidneys can help you protect your kidney health. If a problem with kidney function is suspected, please be sure to consult a medical specialist.

Surfer's myelopathy is a rare condition in which reduced blood flow to the spinal cord during activities that involve excessive backward bending of the spine — such as surfing, yoga, or Pilates — leads to neurological symptoms. If leg paralysis or loss of bladder or bowel control develops after low back pain, go to the emergency room immediately.

Because there are many possible causes, if syncope occurs, please consult a medical specialist to identify the exact cause.

Urinary Tract Infection in Men

#urinary tract infection, #prostatitis, #cystitis, #pyelonephritis, #urethritis, #sepsis, #antibiotics, #cranberry, #sexually transmitted infection, #men's health, #feeling feverish, #body heat, #high fever, #low-grade fever, #body shaking, #feeling cold and shivering, #cold sensation, #frequent urination, #going to the bathroom often, #hand tremor, #body tremor

Urinary tract infection is known to be more common in women, but it also occurs frequently in men, and it is increasing, especially in older men along with diabetes and benign prostatic hyperplasia (enlarged prostate). If it is not treated appropriately at an early stage, it can become chronic or lead to sepsis, so prompt diagnosis and treatment are important.
