Radiation Therapy

#radiation therapy, #anticancer therapy, #cancer treatment, #lack of energy, #lethargy, #persistent fatigue, #dry cough, #frequent mild cough, #persistent cough, #loose stool, #watery diarrhea, #frequent bowel movements

Radiation therapy is a treatment that uses high-energy radiation to damage the DNA of cancer cells, which stops their growth and ultimately destroys them. Some normal cells are also damaged, but they usually recover more quickly than cancer cells and may return to normal function after treatment ends.

Reflux Esophagitis

#reflux esophagitis, #gastroesophageal reflux, #heartburn, #acid regurgitation, #lower esophageal sphincter, #reflux, #stomach acid, #chest ache, #chest pain, #chest tightness, #feeling of stuffiness in the chest, #dry cough, #persistent minor cough, #cough that will not stop

Reflux esophagitis is a condition in which stomach contents flow back up into the esophagus and cause inflammation of the esophagus. Heartburn and acid regurgitation (a sour fluid rising into the throat) are typical symptoms, and the condition can be managed with lifestyle changes and drug treatment. If symptoms persist, please consult a medical specialist.

Retinal Artery Occlusion

#retinal artery occlusion, #retina, #decreased vision, #eye stroke, #central retinal artery occlusion, #high blood pressure, #diabetes, #blurry vision, #difficulty seeing, #hazy vision

Retinal artery occlusion is a condition in which the artery that supplies blood to the retina is suddenly blocked. Like a stroke, in which a blood vessel in the brain is blocked, it damages the nerve cells involved in vision, and it is sometimes called an 'eye stroke.' If sudden vision loss occurs, seek immediate medical attention at an emergency room or ophthalmology department.

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.

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.

Severe Obesity

#severe obesity, #diet, #weight loss, #diabetes mellitus, #bariatric surgery

Severe obesity goes beyond simple overweight; it is a condition in which excessive fat accumulates in the body and causes serious complications. It is not a short-term cosmetic diet but a condition directly tied to life and health, so rather than judging on your own, you should see a specialist for safe, long-term treatment.

Sleep apnea is a condition in which breathing repeatedly stops or becomes markedly reduced for 10 seconds or longer during sleep. If left untreated, it can worsen various systemic conditions such as high blood pressure, heart disease, stroke, and diabetes mellitus. It is not a simple sleeping habit but a condition that may require treatment. If you snore heavily or feel severe daytime sleepiness, please consult an ENT specialist.

Smoking, Health, and Quitting Smoking

#Smoking, #Smoking cessation, #E-cigarettes, #Nicotine, #Tar, #Lung cancer, #Cardiovascular disease, #COPD, #Smoking cessation medication, #Nicotine addiction, #Weakness in arms or legs, #One-sided weakness, #Chest anxiety, #Restlessness, #Unexplained worry, #Feeling down, #Lack of motivation, #Not wanting to do anything

Both regular cigarettes and e-cigarettes are harmful to health. Smoking raises the risk of many conditions, including lung cancer and other cancers, cardiovascular disease, and chronic obstructive pulmonary disease (COPD). Quitting smoking is not easy, but getting help from a medical specialist makes success more likely. If you've decided to quit, please work with a healthcare team rather than trying on your own.

Snoring

#snoring, #sleep, #airway, #uvula, #obesity, #sleep apnea, #otolaryngology, #headache, #severe headache, #migraine, #back-of-head pain, #nasal congestion, #clear nasal discharge, #yellow nasal discharge

Snoring is a sound produced when the airway in the throat narrows during sleep. Although it may seem like a simple sleep habit, it can progress to sleep apnea. Sleep apnea is associated with various systemic conditions, including high blood pressure, heart disease, and stroke. If snoring is severe or accompanied by apnea, please consult an otolaryngology (ear, nose, and throat) specialist.

Spine Surgery

#spine surgery, #disc, #spinal stenosis, #disc herniation, #scoliosis, #spondylolisthesis, #spinal rehabilitation, #osteoporosis, #lumbar spine, #cervical spine, #body swelling, #facial swelling, #leg swelling, #swollen hands and feet, #numbness in hands and feet, #arm numbness, #tingling leg, #weakness in the arms or legs, #difficulty moving one side of the body

Spinal conditions cause a variety of symptoms, including neck and back pain, numbness in the arms and legs, and gait disturbance. Typical conditions include herniated disc (disc herniation), spinal stenosis, and spondylolisthesis. Most spinal conditions are not life-threatening, so the principle is to start with conservative treatment such as drug therapy and physical therapy, and whether and when surgery is needed depends on each patient's condition. Please consult a medical specialist for an accurate diagnosis and direction of treatment.

Stomach cancer is a malignant tumor that develops in the stomach. A malignant tumor is an abnormal mass of cells that harms the body. It is common in Korea, with about 30,000 people diagnosed each year. In its early stages, it often causes no symptoms, which makes it hard to detect early. Regular upper endoscopy is very important for early detection. If you notice unusual symptoms or have concerns, please be sure to see a medical specialist.

Stroke

#stroke, #dementia, #vascular dementia, #high blood pressure, #snoring, #weakness in the arms or legs, #difficulty moving one side of the body

Stroke is a medical emergency that occurs when a blood vessel in the brain becomes blocked or ruptures. A blocked blood vessel is called a cerebral infarction, and a ruptured one is called a cerebral hemorrhage. If symptoms appear, going to the emergency room immediately is the most important way to reduce aftereffects. Stroke is also closely related to dementia. The main symptom of stroke is the loss of a specific bodily function, such as paralysis of the arms or legs. The most important factor in treatment is the golden time (the critical time window for treatment), so please be sure to consult a medical specialist for an accurate diagnosis. If abnormal symptoms appear, call 119 (Korea's emergency number) or go to the emergency room immediately.
