Why am I hacking up white thick phlegm

Hi, Anon.

Thank you for your post.

Have you been ill? Do you have allergies? This may be the cause of excess mucus. With viral bronchitis, small amounts of white mucus are often coughed up. This mucus often changes from white to green or yellow. The color change does not mean there is a bacterial infection. The color change means only that cells associated with inflammation have moved into the airway and are coloring the sputum.

See your doctor if this persists.
