What gastrointestinal symptom is typically associated with hypothyroidism?

In hypothyroidism, a deficiency in thyroid hormones significantly affects the body's metabolism, including gastrointestinal function. This condition often leads to a decrease in the motility of the intestines, which can result in constipation. The slow transit time through the gastrointestinal tract means that fecal matter stays in the colon longer than usual, leading to harder stools and difficulty in bowel movements.

The other symptoms listed—diarrhea, vomiting, and abdominal cramping—are not typically associated with hypothyroidism. Diarrhea may be more common in hyperthyroidism due to increased gastrointestinal motility. Vomiting and abdominal cramping are also not characteristic of hypothyroid patients, as the primary gastrointestinal complaint remains constipation due to reduced intestinal activity. Thus, the association of constipation with hypothyroidism is well-established in clinical practice, making it the correct answer.
