How to recognize high cholesterol, blood pressure, and diabetes by unpleasant odors
Data for the study was collected as part of the National Health and Nutrition Survey from 2011 to 2014. The sample was made on 7417 adults over 40 years old.
As scientists noted, people felt phantom smells, which at the same time were characterized as unpleasant, bad, and sharp. At the same time, the participants in the experiment also reported a history of vascular pathologies, including strokes. In addition, they measured cholesterol and glycated hemoglobin. An increase in blood pressure was also noted.
According to the results of the study, it turned out that against the background of a stroke, the increase in the probability of perceiving phantom odors was at the level of 76%. In congestive heart failure and angina in adults aged 40-59 years and 60+ years, there was a three-fold and 2.8-fold increase in the likelihood of smell perception, respectively.
