4. Mucus
Mucus can form in the throat and along the airways of a person who is suffering from the group. This mucus can be thick and can make it hard to breathe, sleep, and eat. When a person coughs, they may expel mucus from the body. In fact, most of the time a cough is the body’s way of trying to remove the mucus.
There are medications that can help thin out mucus so it can leave the body more easily. Medication can also help reduce the amount of mucus that the body produces. Until the underlying cause of the condition is found and treated, the body will continue to produce mucus that gets caught in the airway. Coughing and hacking may help remove some of the mucus from the body. The color of the mucus can be important. Clear mucus is common, but yellow, green mucus can be a sign of a lung infection.
