1. What Happens When Food Goes Down The Wrong Pipe?
When you swallow, food usually travels from your mouth, down your esophagus, and into your stomach without any problems. However, sometimes, food can accidentally enter your trachea (windpipe) and potentially reach your lungs. This event is known as aspiration.
1.1. Understanding the Normal Swallowing Process
Normally, when you swallow, a flap of tissue called the epiglottis covers your trachea to prevent food from entering. This process ensures that food correctly enters the esophagus.
1.2. What is Aspiration?
Aspiration happens when food, liquid, or foreign objects enter the airway instead of the esophagus. This can lead to various respiratory issues.
1.3. Why Aspiration Is a Concern
When food gets into your lungs, it can cause inflammation, infection, and even pneumonia, known as aspiration pneumonia. Aspiration is particularly risky for young children (under 3 years) and older adults (over 50 years).
2. What Causes Food To Get Stuck In Your Lungs?
Several factors can increase the risk of food getting stuck in your lungs. Understanding these causes can help you take preventative measures.
