Acute Upper Respiratory Infection (Common Cold)

#common cold, #upper respiratory infection, #runny nose, #nasal congestion, #pharyngitis, #tonsillitis, #fever, #cough, #antibiotics, #feverish, #having a fever, #high fever, #low-grade fever, #body shaking, #feeling cold and shivering, #chills, #dry cough, #persistent cough, #cough that won't stop, #stuffy nose, #clear runny nose, #yellow runny nose, #hand tremor, #body tremor

An acute upper respiratory infection is a condition in which a viral or bacterial infection causes inflammation in the upper airway, including the nose, tonsils, pharynx (throat), and larynx (voice box). It includes what is commonly called the "common cold." The main symptoms are runny nose, nasal congestion, sore throat, cough, and fever. Adequate fluids and rest are the basic treatment, but if you have a high fever or severe symptoms, please consult an ENT specialist.

Adenovirus Infection

Adenovirus is a virus that can cause infection in several parts of the body, including the respiratory tract, the eyes (conjunctiva), and the gastrointestinal tract. It mainly affects children, and infections occur throughout the year. Most cases recover with supportive (symptomatic) treatment, but people with weakened immunity can develop severe pneumonia, so caution is needed.

Asthma

#asthma, #bronchi, #allergy, #cough, #wheezing, #shortness of breath, #inhaler, #bronchodilator, #yellow dust, #fine particulate matter, #breathlessness, #difficulty breathing, #labored breathing, #feeling of suffocation, #dry cough, #persistent cough, #cough that won't stop

Asthma is a chronic respiratory condition in which the airways (the passages through which air moves in and out of the lungs) become hypersensitive, often due to allergic reactions, and narrow, causing recurring coughing, wheezing, and shortness of breath. It is sometimes mistaken for a severe cough or cold, which can delay proper treatment. Symptoms can worsen with exposure to yellow dust, fine particulate matter, or pollen. If you have recurring coughing or shortness of breath, please consult a pulmonologist or allergist.

Croup is an emergency condition in which a child suddenly has difficulty breathing. Symptoms typically worsen at night and can become life-threatening, so prompt evaluation by a pediatric specialist or emergency care is needed.

Deep Vein Thrombosis (DVT)

#deep vein thrombosis, #DVT, #blood clot, #pulmonary embolism, #leg swelling, #economy class syndrome, #dry cough, #persistent cough, #cough that won't stop

Deep vein thrombosis is a condition in which a blood clot (a lump formed when blood coagulates) develops in a deep vein of the leg and blocks the vessel. Leg swelling and pain are the main symptoms, and if the clot travels to the lungs, a dangerous complication called pulmonary embolism can occur. If you suspect symptoms, please consult a medical specialist right away.

Esophageal Diseases (Reflux Esophagitis and Esophageal Cancer)

The esophagus is a tube about 25 cm long that carries food from the mouth to the stomach. Reflux esophagitis and esophageal cancer are the main esophageal diseases. If you have symptoms such as heartburn, acid regurgitation (a sour taste rising into the throat), or a feeling that food is getting stuck, please consult a medical specialist.

Hand, foot, and mouth disease is a viral infection that causes blisters and rashes on the hands, feet, and inside the mouth. It mainly affects infants and young children, and most cases resolve on their own within 7 to 10 days. Personal hygiene, such as handwashing, is the most important form of prevention.

When a child suddenly becomes ill, it can be difficult to decide whether to go to the emergency room right away or to wait and see a local clinic. Unlike adults, children can worsen quickly, so if your child looks or acts differently from usual, do not hesitate to seek medical care.

Kidney Cancer

Kidney cancer is a malignant tumor that develops in the kidney. There are almost no symptoms in the early stages, so it is difficult to notice on your own, and in most cases it is found incidentally during a health checkup. Even without symptoms, it is important to detect it early through regular health checkups. If an abnormal finding is detected or you have any concerns, please be sure to consult a medical specialist.

Lung Cancer

#lung cancer, #non-small cell lung cancer, #small cell lung cancer, #lung cancer screening, #low-dose CT, #targeted therapy, #immunotherapy, #bronchoscopy, #low energy, #lethargy, #persistent tiredness, #breath holding, #difficulty breathing, #shortness of breath, #choking sensation, #dry cough, #persistent cough, #cough that won't stop, #nausea, #feeling like vomiting, #vomiting, #weakness in the arms or legs, #one-sided weakness

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.

Osteoporosis

#osteoporosis, #bone density, #compression fracture, #menopause, #calcium, #vitamin D, #bisphosphonates, #fall prevention, #vertebral fracture, #femoral fracture, #dry cough, #persistent cough, #cough that won't stop

Osteoporosis is a condition in which bones become weaker and can break easily even from a minor impact. There are often no symptoms, and it is frequently discovered only after a fracture occurs. The risk is higher in postmenopausal women and older adults, so regular bone density testing and preventive lifestyle habits are important. Please be sure to discuss treatment options with a medical specialist.

Osteoporosis in Patients with Asthma

#asthma, #osteoporosis, #steroids, #vertebral compression fracture, #bone density, #calcium, #vitamin D, #dry cough, #persistent cough, #cough that won't stop

Long-term use of steroid medications used to treat severe or chronic asthma can lead to osteoporosis. When osteoporosis becomes severe, a vertebral compression fracture can occur even with minor impact, so caution is needed. Please have regular bone density testing and follow up with a medical specialist.

Parainfluenza Virus Infection

#parainfluenza, #croup, #laryngotracheobronchitis, #children, #infants, #barking cough, #respiratory infection, #dry cough, #persistent cough, #cough that won't stop

Parainfluenza virus causes acute respiratory illness in infants and young children. It is a major cause of croup (laryngotracheobronchitis), which can produce a harsh, barking cough or hoarseness. Most cases recover with supportive care, but please consult a medical specialist if symptoms are severe.

Secondhand Smoke (Passive Smoking)

#secondhand smoke, #passive smoking, #smoking cessation, #heart disease, #stroke, #lung cancer, #diabetes mellitus, #respiratory system, #headache, #a splitting headache, #migraine, #back-of-head pain, #dry cough, #persistent cough, #cough that won't stop, #blood-streaked sputum, #coughing up blood, #weakness in arms and legs, #difficulty moving one side of the body

Secondhand smoke exposure, also called passive smoking, means that a person who does not smoke breathes in smoke from a smoker's cigarette. Tobacco smoke contains thousands of chemicals, including carcinogens (substances that can cause cancer), and long exposure in an enclosed space can be harmful even to nonsmokers. If you are concerned about secondhand smoke, please consult a medical specialist.

Vertebral Compression Fracture

#vertebral fracture, #compression fracture, #spine, #back pain, #osteoporosis, #fall, #fracture in older adults, #bone cement, #dry cough, #persistent cough, #cough that won't stop

A vertebral compression fracture occurs when the impact of a fall onto the buttocks is transmitted to the spine, although in severe osteoporosis a vertebra can also collapse gradually without a significant impact. Severe back pain, including pain with coughing, is a main symptom. In older adults, prolonged bed rest during recovery can lead to complications such as pneumonia or pressure sores, so caution is needed. If you have back pain after a fall, please consult an orthopedic specialist.
