Perhaps, everybody has experienced coughing. There is a light, there is heavy. There are phlegm, there is also dry.
In addition, maybe because it was unusual, people who ignore the cough. The problem, if left untreated the infection can occur. And if it is acute, most likely difficult to treat.
Coughing is a reflex physiology to protect the body from foreign objects entering the throat. In the airway in the throat is vibrating a lot of hair that continue to move and serve to wipe out foreign objects entering the throat, the body will try to remove it by coughing. However, coughing can also be a symptom of something diseases.
The cause and symptoms of cough
Cough is caused by inflammation of the mucous lining the respiratory tract. There is also acute cough up phlegm from infections caused by bacteria or viruses, for example tuberculoses, influenza, and measles. While coughing up phlegm that is not caused by infection, including allergies, asthma, or dust.
In addition, there are also coughing up phlegm that is not caused by infection foods that stimulate the throat. There is also due to cancer. Coughs due to smoking are difficult to overcome people often only symptomatic with cough medicine. Cough with phlegm in people who are sick due to abnormalities in the body, especially in the respiratory tract or bronchitis.
Coughing up phlegm is commonly caused by influenza. The symptoms are high fever accompanied by a rigid body muscles, sneezing, nasal congestion, and sore throat. However, coughs with phlegm also arise from inflammation of the lungs.
If not treated promptly, acute coughing can occur. When you have, acute chances are difficult to treat. Additionally, excessive coughing will cause infection. Coughing up phlegm that is too often will make the throat into the wound and cause blockage of the respiratory tract.
In the respiratory epithelium lining there is a thin layer of mucus that coats and he cleaned by the movement of an escalator mucosal. Cough act clean when too much airway foreign bodies are inhaled or if there are a number of mucus that is too much. In addition to the above cough can also be caused by odor stimuli, airway contraction (e.g., in asthma) or inflammation of the airways. Essentially all of which can stimulate cough receptors causes the cough.
Coughing can also be caused by deliberate action. However, between reflexes and intentional mechanism is the same. A cough begins with breathing in and then followed by the closure of the epiglottis. Then, the diaphragm relaxation accompanied by a contraction of the muscles that function to reduce the chest cavity. Due to a decrease in the pressure in the chest cavity, chest cavity expands. So when the epiglottis to open air will come out of the respiratory tract quickly to clean up discharges.
Once we consider the above discussion, we can conclude that cough is the body’s defense mechanism. However, there are some indications that show that we suffer cough is abnormal. The most important indication is the cause of cough, presence or absence of secretions that accompany the long duration of cough and cough.
If the cough is dry (no discharge), then we can suppress cough by giving antitussives. However, if there is discharge then we should not give antitussives because it was feared would happen respiratory tract obstruction.
Drugs used to treat coughs, among others:
• Antitusive: Working suppress cough reflex. Commonly used include codeine, and dextromethorphan noskapin.
• Expectorants: Drugs used to stimulate a cough so that the phlegm can be removed so as not to clog the airways. OTC drugs are often used glyceryl guaikolat and guaifenesin.
• Mukolitik: Lowering the viscosity of mucus / phlegm, making it easier for spending sputum. Used in a thick phlegm. Mukolitik Example: N-acetylcysteine, karbosistein, ambroksol, and bromheksin.
