Abstract:
OBJECTIVE:To study the effects of thyroxine on orocaecal transit time in a group of elderly hypothyroid patients on long-term thyroxine replacement therapy. DESIGN:Measurement of the effect of withdrawal and subsequent replacement of thyroxine replacement therapy on orocaecal transit time. PATIENTS:Fifteen elderly, previously hypothyroid patients on full replacement therapy with oral thyroxine were studied. There were 11 females and four males, aged 60-94 years (median 78 years) receiving initially 50-200 micrograms of oral thyroxine daily (median 100 micrograms). MEASUREMENTS:Serum TSH and FT4 were measured by radioimmunoassay and orocaecal transit time assessed using a lactulose hydrogen breath test. These tests were repeated 7 days after withdrawal of thyroxine replacement and again 7 days after subsequent reinstatement of therapy. RESULTS:On withdrawal of therapy, the median transit time increased from 75.0 to 135 minutes (P less than 0.01), the median TSH increased from 1.8 to 2.3 mU/l (P = NS) and the median FT4 decreased from 13.7 to 10.6 pmol/l (P less than 0.01). On reinstatement of therapy, the median transit time decreased to 95 minutes (P = NS), the median TSH decreased to 1.1 mU/l (P = NS) and the median FT4 increased to 14.1 pmol/l (P less than 0.01). CONCLUSIONS:These findings demonstrate the sensitivity of the small bowel to changes in thyroid hormone status and suggest that constipation arising as a result of this hypomotility may well be an early physical manifestation of hypothyroidism.
