Disease at a Glance

Nontuberculous mycobacterial (NTM) lung disease is an infectious condition caused by certain types of mycobacteria. Some people with NTM lung disease have no signs or symptoms, while others experience a severe cough, hemoptysis (coughing up blood), shortness of breath, fatigue, fever, night sweats and/or weightloss. Mycobacteria are found naturally in soil and water. Most people who are exposed to these bacteria do not become sick. However, people who have a weakened immune system or other health conditions (i.e. chronic obstructive pulmonary disease, bronchiectasis, pneumoconiosis, cystic fibrosis, and previous tuberculosis) have an elevated risk of developing NTM lung disease.

Respiratory System

The respiratory system is made up of the lungs and the nose, mouth, throat, voice box, windpipe, diaphragm, and muscles of the chest wall. This system controls breathing, providing the body with oxygen and getting rid of carbon dioxide. Common symptoms of problems in the respiratory system include chronic cough, shortness of breath, chronic chest pain, coughing up blood, and chronic mucus production. Diseases of the respiratory system may be diagnosed and treated by a pulmonologist.
