When you have a cold or fatigue, you may feel a sore throat, and seeing a doctor is usually your choice, but when your sore throat symptoms do not improve but rapidly worsen, and you have difficulty swallowing, increased painful swallowing, a feeling of foreign body blockage in the throat, or even breathlessness, you should beware that you may be suffering from the disease of acute epiglottitis. This disease is dangerous and can be life-threatening if not treated promptly. When we eat, it can cover the vocal cords to prevent food from choking into the airway, but when the epiglottis is swollen, it can affect swallowing and eating, or it can block the vocal cords and cause death by asphyxiation. As the onset of epiglottitis is more rapid, coupled with the painful swallowing saliva is not easy to swallow, but also easy to cause laryngeal obstruction, so the first priority is to go to the Department of Five Gynecology to check whether the disease, if the diagnosis requires hospitalization and observation of respiratory conditions, and if necessary, the possibility of tracheotomy. Of course, acute tonsillitis and acute pharyngitis can also present with obvious sore throat symptoms, but they do not present with dyspnea or even laryngeal obstruction, and a simple laryngeal examination by an otolaryngologist can make a differential diagnosis. We mentioned above that fatigue and cold and flu are common triggering factors, but recently we found that the rate of diabetic patients among patients with epiglottitis is increasing in our clinic. The case was treated with tracheotomy to enhance anti-infection and blood sugar control before it was gradually removed from life threatening. I would like to remind the majority of elderly people when you have unexplained sore throat and rapid aggravation of the impact of eating and swallowing, you must be alert to go to the quintuplegia to check whether the disease of acute epiglottitis, and check the blood sugar situation, because recessive diabetic patients may not be easy to control blood sugar more prone to infection symptoms, the above-mentioned tracheotomy diabetic elderly patients do not know their diabetic condition in advance, this type of patients These patients often do not have any precipitating factors before the onset of the disease and wait until the blood sugar is tested during the hospital treatment to find out the diabetic condition. With the gradual improvement of living standards, regular blood glucose testing is also an important aspect of self-care for middle-aged and elderly people, not only for early detection of diabetes and early treatment, but also for prevention of life-threatening diseases such as acute epiglottitis.
