About Bronchial Disorders
When you breathe in, the air travels down through your trachea (windpipe). It then goes through two tubes to your lungs. These tubes are your bronchi. Bronchial disorders can make it hard for you to breathe.
The most common problem with the bronchi is bronchitis, an inflammation of the tubes. It can be acute or chronic. Other problems include:
- Bronchiectasis - a condition in which damage to the airways causes them to widen and become flabby and scarred
- Exercise-induced bronchospasm - a breathing problem that happens when your airways shrink while you are exercising
- Bronchiolitis - an inflammation of the small airways that branch off from the bronchi
- Bronchopulmonary dysplasia - a chronic lung condition in infants, most often premature infants
It sits within Lungs and Breathing.
The lead U.S. institute for this subject is the National Heart, Lung, and Blood Institute.
When to speak to someone. Reading about a topic cannot tell you whether it applies to you. Speak to a doctor or pharmacist if symptoms are severe, sudden, getting worse, or simply not going away — and seek emergency care immediately for chest pain, breathing difficulty, sudden weakness or confusion, or a serious allergic reaction.
Research on Bronchial Disorders
14,106 studies areregistered for this condition on ClinicalTrials.gov, the U.S. National Library of Medicine's public registry. A selection is below — the links go straight to the registry entry, not to a summary of ours.
What a registered study does and does not mean. Registration means a study exists and has been declared publicly. It says nothing about whether the treatment being tested works, is safe, or is available to you. Many studies find no benefit — that is what research is for. Never seek out an experimental treatment on the strength of a registry entry alone.
