Decreased orocaecal transit time, as measured by the exhalation of hydrogen, in hyperthyroid cats.
Orocaecal transit time was assessed in healthy cats and cats with hyperthyroidism by means of the breath hydrogen test using a standard liquid meal with lactulose. The median transit time in 10 healthy cats was 98 minutes (range 60 to 150 minutes) and 90 minutes (range 75 to 150 minutes) in a repeated assessment. The median transit time in 10 cats with hyperthyroidism was 53 minutes (range 45 to 150 minutes) which was significantly more rapid (P < 0.05) than in the healthy cats.
