Background:
The association between ulcerative colitis and thyroid disorders has been previously reported. However, most reports consist of single case description, and a systematic assessment of this relationship has only sporadically been investigated.
Aims:
To study a cohort of patients with ulcerative colitis to establish the prevalence of hyper- and hypothyroidism.
Material And Methods:
During a four-year period, we studied thyroid function in 162 ulcerative colitis patients (62 men, 100 women, age range 18-78 years).
Results:
Thyroid dysfunction was present in 4 patients (2.5%) of the overall population and was represented by both hypo- (3 patients) and hyperthyroidism (1 patient). The incidence of this kind of thyroid dysfunction was significantly (p=0.03) lower than that found in a large (more than 5000 subjects) control group.
Conclusions:
We conclude that the prevalence of hyper-/hypothyroidism is relatively low in patients with ulcerative colitis, at least in our country, and does not justify a systematic investigation of the thyroid function, except in selected cases, probably those with scarce or no response to standard therapeutic measures.

Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
