Abdominal Wall Hernia

#abdominal wall hernia, #hernia, #laparoscopy, #robotic surgery, #minimally invasive surgery, #bowel obstruction, #abdominal surgery, #stomachache, #abdominal pain, #belly ache, #gut pain, #dry cough, #minor cough, #persistent cough, #unable to pass stool, #difficulty passing stool, #hard stools

An abdominal wall hernia is a condition in which the abdominal wall around a surgical incision weakens after abdominal surgery, allowing tissue from inside the abdominal cavity to push out. Early detection and surgery may allow a faster recovery. If you feel an unusual lump in the abdomen or develop sudden abdominal pain, please consult a medical specialist.

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, #respiratory infection, #conjunctivitis, #gastroenteritis, #childhood infection, #virus, #sore throat, #scratchy throat, #pain when swallowing, #feverish, #having a fever, #high fever, #low-grade fever, #dry cough, #persistent cough, #cough that won't stop, #loose stool, #watery diarrhea, #frequent trips to the bathroom, #pain when urinating, #burning urination, #urinating frequently, #going to the bathroom often, #blood in urine, #red urine, #bloody urine

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.

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.

Comparing the Common Cold, Influenza (Flu), and COVID-19

#common cold, #flu, #COVID-19, #influenza, #respiratory infection, #comparison, #mask, #handwashing, #sore throat, #scratchy throat, #pain when swallowing, #feeling feverish, #body heat, #high fever, #low-grade fever, #body shaking, #feeling cold and shivering, #cold sensation, #dry cough, #persistent minor cough, #cough that will not stop, #stuffy nose, #clear runny nose, #yellow runny nose, #hand tremor, #body tremor

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, #thoracic pain, #chest pain, #ribs, #sternum, #cartilage, #anti-inflammatory drugs, #chest ache, #pain in the chest, #chest tightness, #feeling of stuffiness in the chest, #shortness of breath, #difficulty breathing, #labored breathing, #feeling of suffocation, #dry cough, #persistent minor cough, #cough that will not stop

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.

Croup

#croup, #barking cough, #difficulty breathing, #common cold, #airway swelling, #breath holding, #difficulty breathing, #shortness of breath, #choking sensation, #dry cough, #persistent cough, #cough that won't stop, #body swelling, #facial swelling, #leg swelling, #swelling of the hands and feet

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.

Dysphagia (Swallowing Disorders)

#swallowing disorder, #dysphagia, #aspiration, #swallowing rehabilitation, #diet modification, #stroke, #swallowing test, #fever, #feeling hot, #high fever, #low-grade fever, #dry cough, #minor cough, #persistent cough

Dysphagia is a condition in which the ability to swallow food or drink is impaired. If 'aspiration,' in which food enters the airway, occurs, complications such as pneumonia may develop. If you suspect a decline in swallowing function, please consult a medical specialist for examination and testing.

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.
