They found that among the non-smokers, lung cancer was accurately identified in 128 subjects and misdiagnosed in only five. Among smokers, the electronic nose correctly identified 114 people as having lung cancer, misdiagnosing five. The findings were presented on September 9 in the European Respiratory Society (ERS) Annual Congress in Barcelona.
Researchers were able to use a simple breath test to identify patients suffering from heart failure, according to a March 2013 paper published in the Journal of the American College of Cardiology.
Cleveland Clinic researchers collected breath samples from 41 patients. Twenty five were officially diagnosed with “acute decompensated heart failure.” Sixteen patients had other cardiovascular conditions but showed no signs of heart failure.
The kidneys are responsible for removing toxic chemicals from the blood by creating urine. In kidney failure, also known as end-stage renal disease, the kidneys become so damaged that they are no longer able to filter waste products and toxic chemicals from the blood. When this happens, the dangerous toxins and waste not discharged from the body accumulate and affect nearly every part of the body. The fishy breath odor can occur when kidney failure affects the respiratory system and causes breathing problems.
Both digestive conditions can delay or prevent food from processing efficiently from the stomach. When food doesn’t move through the digestive system, it can start to decay. Small amounts of undigested food may even regurgitate and cause bad breath. Dentists may also detect GERD in patients when they notice an inflamed red throat and acid erosion in the teeth.
