Upper and lower respiratory tract
The upper respiratory tract is composed of the nose, throat, sinuses and larynx. It is responsible for the intake of air and its passage to the lungs. It also includes organs that are involved in other important functions such as smelling, tasting, and hearing.
Two diseases of the upper respiratory tract are acute bronchitis and tonsillitis. Acute bronchitis is an inflammation of the lower airways (bronchi) caused by a viral or bacterial infection. Symptoms may include coughing up thick mucus, chest discomfort and pain, fatigue, sore throat and fever. Treatment typically involves rest with fluids; antibiotics may be prescribed depending on a diagnosis from your doctor.
Tonsillitis is an inflammation of the tonsils due to either a virus or bacteria infection causing symptoms such as sore throat (usually worse on one side), difficulty swallowing, swollen lymph nodes around neck area, fever/chills , bad breath etc.. Treatment typically consists of over-the-counter medications to alleviate some symptom relief such as ibuprofen or acetaminophen for pain relief; antibiotics may also be prescribed if a bacterial infection is confirmed via lab tests done by your physician. In severe cases where frequent episodes occur surgery could be considered to remove them completely however this should only really be considered after consultation with an ENT specialist who can discuss all available options with you first.
