Chronic Obstructive Pulmonary Disease (COPD)

#COPD, #chronic obstructive pulmonary disease, #airway obstruction, #smoking, #pulmonary function test, #bronchodilator, #smoking cessation, #emphysema, #dry cough, #persistent minor cough, #cough that will not stop

Chronic obstructive pulmonary disease (COPD) is a chronic lung disease in which the airways (the passages through which air travels) gradually narrow, making breathing difficult. The leading cause is smoking. Airways that have narrowed are mostly not restored, so early detection and smoking cessation are especially important. If cough, sputum, or shortness of breath persists, please consult a pulmonology and allergy specialist.

The common cold, influenza (flu), and COVID-19 are all respiratory infectious diseases caused by viruses, but the causative viruses and symptoms differ. It is often difficult to tell the three apart from symptoms alone, so if you have any abnormal symptoms, please consult a medical specialist.

Costochondritis

Costochondritis is a condition in which the cartilage that connects the ribs to the breastbone (sternum) becomes inflamed. Chest pain is the main symptom, and because the symptoms can resemble those of pneumothorax or heart disease, an accurate diagnosis is important. If chest pain persists, please consult a medical specialist.

#hepatitis B, #chronic hepatitis, #antiviral drugs, #cirrhosis, #liver cancer, #HBV, #vaccination, #liver health, #lack of energy, #listlessness, #persistent tiredness, #dry cough, #persistent minor cough, #cough that will not stop

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.

Liver Transplantation

Liver transplantation is an operation that replaces a liver that has lost its function with a healthy liver, and it is one of the treatment options for several serious liver diseases, such as liver failure caused by cirrhosis and liver cancer. Since it was first performed in Korea in 1988, advances in technology and medication have led to more than 1,500 transplants a year at present, and the overall surgical success rate is reported to be about 90 to 95%. Liver transplantation is an important decision for both the recipient and the donor, so please discuss it thoroughly with your treating physician before making a decision.

Pneumonia in Older Adults

Pneumonia in older adults generally refers to pneumonia that occurs at age 65 or older. Pneumonia is inflammation of the lungs caused by infection with bacteria, viruses, or other organisms. More than 50% of people with pneumonia and more than 90% of people who die of pneumonia are aged 65 or older. In older adults, symptoms are often not obvious, so diagnosis is easily delayed. If you have suspected symptoms, please consult a pulmonology and allergy specialist immediately.

Pneumothorax is a condition in which air collects between the lung and the chest cavity (the space inside the chest). The chest cavity is the space that surrounds the lungs. It mainly occurs on one side of the chest, and chest pain and difficulty breathing are the typical symptoms. If you suspect symptoms, please consult a medical specialist.

RSV (respiratory syncytial virus) is the most common virus that causes bronchiolitis (inflammation of the small airways) and pneumonia in infants and young children. It is highly contagious, and most children are infected at least once before the age of 2. Premature infants, children with congenital heart disease, and people with weakened immunity need to take extra care.

Urinary incontinence does not occur only in women; it also occurs in men, and the number of men with urinary incontinence is increasing with population aging and a rise in prostate disease. It often occurs after prostate surgery or because of benign prostatic hyperplasia (enlarged prostate), diabetes, and similar conditions. It can be managed with proper care, including Kegel exercises, drug treatment, and, when necessary, surgical treatment, so please consult a medical specialist.
