Smell and taste in children with simple obesity.

In 30 children, aged 10-16 years and suffering from simple obesity, significantly lowered odour detection thresholds were noted. The thresholds were lower than the average for a given age group in around 20% of obese children in cases of odours stimulating olfactory nerve and in around 57% in cases of substances stimulating olfactory and trigeminal nerves. Odour identification thresholds were similarly affected, with identification of olfactory nerve plus trigeminal nerve stimulating odours affected more than twice as frequently. In 77% cases also the electrogustometric thresholds were found below the normal range values when anode was used as the stimulating electrode. The detected alterations may be linked to metabolic disturbances, which accompany simple obesity.
