Document Summary
Tuberculosis (tb: weight loss, night sweats fever tiredness loss of appetite swelling in the neck. It consists of water, salts, antibodies and other immune system cells. After being produced in the respiratory tract, most of it goes down the back of the throat and is swallowed. Brown phlegm may indicate possible bleeding, and if so, is likely to be caused by bleeding that happened a while ago. Bright red or pink phlegm means the bleeding has happened more recently. Black mucus may indicate the presence of a fungal infection. When the nasal cavity is congested, the tissues are swollen and inflamed, which slows the passage of mucus through the respiratory tract. When this happens, the mucus becomes thicker and cloudy or white. Yellow mucus suggests that immune cells are starting to work at the site of the infection or another type of inflammatory insult. Green phlegm indicates a widespread and robust immune response.
