10 Lung Infection Symptoms
Symptom #6: Headache
Headaches may be symptoms of lung infections. Such headaches usually occur as a result of breathing difficulties. As previously mentioned, the body requires oxygen to carry out various functions. It also requires to get rid of the carbon dioxide. This exchange of oxygen and carbon dioxide happens in the lungs during the breathing process.
However, because lung infections interfere with the breathing process, they cause the body to get less oxygen and to get rid of less carbon dioxide. When this goes on for some time, the bloodstream ends up having less oxygen and increased amounts of carbon dioxide, a condition known as hypoxia. This strains tissues and organs including the heart and the brain. The resultant strain leads to headache, besides other general aches.
