Drinking Water and Aspiration

When I travel, I either order bottled spring water or bring my LARQ UV water bottle to reduce exposure to MAC bacteria.


Wondering how the water we drink—going into our stomachs—could lead to a MAC infection in our lungs???🤔🤔🤔


The answer comes down to two key factors: inefficient swallowing and gastric reflux.
We all micro-aspirate liquids into our lungs throughout the day. This might happen when something “goes down the wrong pipe,” due to swallowing issues and coughing. For those with healthy lungs and immune systems, occasional micro-aspirations are not a concern. However, for people with impaired airways, this can be a potential pathway for inflammation and infection.


Gastroesophageal reflux (GERD) is another way unwanted substances can enter the lungs. Both acid and non-acid gastric reflux can rise from the stomach and be aspirated into the airways. If this liquid contains bacteria that haven’t been neutralized by stomach acid, it may contribute to infection.


To help reduce reflux, consider these GERD precautions:
🦠 Raise the head of your bed
🦠 Avoid eating for several hours before lying down
🦠 Maintain a healthy weight
🦠 Avoid trigger foods
🦠 Use an alginate


Beyond addressing swallowing issues and GERD, we can also minimize bacterial exposure by drinking sterile water. If you opt for spring water, avoid water coolers, as MAC biofilm may line the inside of the machine. The same concern applies to refrigerator water dispensers, ice makers, and Brita-style charcoal filters.


As I’ve mentioned in previous posts about environmental exposure, not everyone with bronchiectasis will develop these types of infections. However, there is about a 25% chance, and these precautions can help lower that risk.


Some BE and MAC specialists advise patients to simply live their lives without fixating on bacteria, while others recommend preventive measures. It’s best to discuss your individual situation with your doctor to determine the right approach for you.


Remember, bronchiectasis is a lifelong condition, and you can always make changes gradually over time.
