Health Tip: Do You Have Bronchitis?

(HealthDay News) -- Bronchitis is a respiratory disease characterized by inflamed mucus membranes in the lungs.

The National Heart, Lung, and Blood Institute says common warning signs of bronchitis include:

• Persistent cough lasting 10 days to 20 days.
• Coughing up mucus, which may be clear, yellow or green. The latter two indicate a bacterial infection.
• Wheezing when breathing, tightness in the chest or chest pain.
• Low-grade fever.
• Shortness of breath, especially during exercise.

If you have any of these symptoms, you should visit your doctor without delay.
