Benign paroxysmal positional vertigo (BPPV) occurs when tiny particles called otoconia become dislodged from the balance organ of the inner ear (the vestibular system) and enter the semicircular canals. Otoconia are small crystals made of calcium carbonate, sometimes described as "ear stones." The main symptom is a spinning sensation that occurs with changes in head position. If you experience dizziness, please consult an ENT specialist.

Early Detection and Management of Liver Disease

#liver disease, #liver cancer, #cirrhosis, #hepatitis B, #hepatitis C, #fatty liver, #nonalcoholic steatohepatitis, #hepatectomy, #minimally invasive surgery, #early screening, #alcohol abstinence, #lack of energy, #listlessness, #persistent tiredness, #nausea, #feeling about to vomit, #vomiting

The liver is a 'silent organ.' Even as damage progresses, there are no obvious symptoms in the early stage, so fatigue, loss of appetite, and weight loss are often dismissed as minor, and the disease is often discovered only after it has progressed to cirrhosis or liver cancer. Regular checkups are the most important way to protect liver health.

A gastrointestinal stricture is a narrowing of a passage in the digestive tract, such as the esophagus, stomach, or intestine.

Depending on the cause and location, it is managed with endoscopic treatment or surgery. If you have these symptoms, please be sure to see a medical specialist.

Hematopoietic Stem Cell Transplantation (HSCT)

#hematopoietic stem cell transplantation, #bone marrow transplant, #autologous transplant, #allogeneic transplant, #graft-versus-host disease, #blood cancer, #leukemia, #lymphoma, #loose stool, #watery diarrhea, #frequent trips to the bathroom

Hematopoietic stem cell transplantation (HSCT) is a treatment that transplants hematopoietic stem cells, the cells that give rise to white blood cells, red blood cells, and platelets. It was previously known as bone marrow transplantation, but the name changed once it became possible to collect these cells from peripheral blood as well. It is mainly used to treat blood-related malignancies, and both the treatment process and follow-up care afterward are important.

Hepatitis B is a liver inflammation caused by the hepatitis B virus. In Korea, about 30% of cirrhosis cases and 45% of liver cancer cases are associated with hepatitis B. It can be managed with proper care, including vaccination and consistent treatment, and regular checkups are important to help keep it from progressing to cirrhosis or liver cancer.

Iron deficiency anemia is a condition in which a lack of iron in the body leads to a shortage of red blood cells. Common symptoms include pallor, fatigue, dizziness, and shortness of breath during exercise. It occurs especially frequently in women of childbearing age. If anemia persists for a long time, it can place strain on the heart, so identifying the cause and receiving appropriate treatment is important. If you suspect these symptoms, please consult a hematology-oncology specialist.

Lung cancer is a malignant tumor that develops in the bronchi or lungs and is the leading cause of cancer death in Korea. It often causes no symptoms in its early stages, so regular screening is important for high-risk groups. Smoking is the leading cause, and quitting smoking is the most effective way to help prevent it.

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.
