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.

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.

Fine Dust (Particulate Matter) and Health

#particulate matter, #fine particulate matter (PM2.5), #Asian dust (yellow dust), #respiratory system, #mask, #KF80, #KF94, #asthma, #air pollution, #dry cough, #minor cough, #persistent cough

Fine dust consists of tiny particles floating in the air. It directly affects the respiratory tract, including the nose, bronchi, and lungs, and can also harm the whole body, including the heart, brain, and blood vessels, through the bloodstream. Long-term exposure increases the risk of asthma, reduced lung function, and cardiovascular and cerebrovascular disease. On days when fine dust levels are high, limit outdoor activities, and people at high risk are advised to wear a health protection mask.

Fluid Intake and Health

#fluid intake, #water, #empty stomach, #bowel movement, #dehydration, #health drinks, #digestion

The body keeps its fluid balance by triggering thirst when fluid is low and excreting excess fluid in the urine. Rather than following a fixed standard, the basic principle is to drink enough when you feel thirsty. Drinking water on an empty stomach in the morning can replace fluid used up overnight and may help bowel movement.
