Thyroid dysfunction impacts intestinal absorption. Hyperthyroid patients commonly experience fat malabsorption (steatorrhoea), while both hyper- and hypothyroid patients show carbohydrate malabsorption, more frequently in hypothyroidism.

Area of Science:

  • Endocrinology
  • Gastroenterology
  • Internal Medicine

Background:

  • Thyroid hormones significantly influence metabolic processes, including gastrointestinal function.
  • Altered thyroid states are suspected to affect nutrient absorption.
  • Understanding these effects is crucial for managing patients with thyroid disorders.

Purpose of the Study:

  • To investigate intestinal absorptive functions in patients with hyperthyroidism and hypothyroidism.
  • To determine the prevalence of fat and carbohydrate malabsorption in these conditions.
  • To explore the relationship between thyroid dysfunction and malabsorption.

Main Methods:

  • Evaluated intestinal absorptive functions in 11 hyperthyroid and 14 hypothyroid patients.
  • Assessed for steatorrhoea (fat malabsorption) and D-xylose malabsorption (carbohydrate malabsorption).

  • Examined jejunal mucosal morphology and vitamin B12 absorption in a subset of patients.

    • Main Results:

    • Steatorrhoea was common in hyperthyroid patients but rare in hypothyroid patients.
    • D-xylose malabsorption was observed in both groups, being more prevalent in hypothyroidism.
    • Occasional vitamin B12 malabsorption was noted in hypothyroid patients; jejunal mucosa was largely unremarkable.

    Conclusions:

    • Thyroid dysfunction is casually related to both fat and carbohydrate malabsorption.
    • Hyperthyroidism is associated with increased fat malabsorption, while hypothyroidism shows a higher incidence of carbohydrate malabsorption.
    • These findings highlight the significant impact of thyroid status on intestinal absorptive capabilities.
