Many outpatients come to the clinic already very serious, always think pharyngitis is not a major disease do not take it seriously, and finally developed to a serious degree, treatment will be more difficult than the initial stage of the disease, the patient will also suffer more. This is why pharyngitis is not a trivial matter, so don’t wait until complications develop before paying attention. There are many complications of pharyngitis, which are summarized below: 1. In acute pharyngitis, in addition to sore throat, there will be fever, cold, headache, body aches, poor appetite, dry stools, dry mouth and other systemic toxic reactions. When there is bacterial infection, the blood white blood cell count increases. If the sore throat is severe and affects swallowing, it also causes nutritional and metabolic imbalance in the body. If the treatment is not timely, or recurrent, it can become chronic. 2, downward development, can invade the larynx, trachea and other lower respiratory tract, causing acute laryngitis, bronchitis, bronchitis and pneumonia; if the pathogenic bacteria and toxins invade the blood circulation, it can cause systemic complications, such as acute nephritis, sepsis, rheumatism, etc., which is very harmful to the body. 3, resulting in a decrease in the resistance of the pharynx, when the climate is cold, hot, dry, wet changes, the mucous membrane of the heating, humidification regulation role is weakened, cilia activity and decomposition and phagocytosis is not enough, bacteria and viruses are easy to stay in the local reproduction, becoming a chronic infection foci. Inflammation of the pharynx infection spread to other systems, can be complicated by chronic laryngitis, nephritis, heart disease, etc. 4, chronic pharyngitis patients often feel discomfort in the pharynx, a little cold, tired, or talk more, longer without water, will feel sore throat, burning aggravated, pharyngeal itching caused by bouts of irritating cough, affecting the rest. If it is dry or atrophic pharyngitis, the pharynx is obviously dry, speech and saliva also feel hard, need to drink water frequently to moisten, and even need to get up at night to drink water several times. 5, manifested as a foreign body feeling in the throat, often make uttering and swallowing movements, hoping to remove foreign bodies, but these ineffective throat-clearing actions can only aggravate the original discomfort. As a result, patients suspect that they have a tumor in the pharynx, throat or esophagus, causing a heavy mental burden and depression. Some people snore due to the thickening of the mucous membrane in the pharynx, which affects the smoothness of breathing. Therefore, it is better to consult a doctor as soon as possible when you feel discomfort in the throat, or you may suffer more when you can’t bear it anymore.
