Medications that are used to treat an overactive thyroid (hyperthyroidism) may cause hypothyroidism. These drugs include methimazole ( Tapazole ) and propylthiouracil (PTU). The psychiatric medication, lithium (Eskalith, Lithobid ), is also known to alter thyroid function and cause hypothyroidism. Interestingly, drugs containing a large amount of iodine such as amiodarone ( Cordarone ), potassium iodide (SSKI, Pima), and Lugol's solution can cause changes in thyroid function, which may result in low blood levels of thyroid hormone.
Proctocolectomy and ileoanal reservoir. An ileoanal reservior is an internal pouch made from the patient's ileum. This surgery is a common alternative to an ileostomy and does not have a permanent stoma. Ileoanal reservoir is also known as a J-pouch, a pelvic pouch, or an ileoanal pouch anastamosis. The ileoanal reservior connects the ileum to the anus. The surgeon preserves the outer muscles of the patient's rectum during the proctocolectomy. Next, the surgeon creates the ileal pouch and attaches it to the end of the rectum. Waste is stored in the pouch and passes through the anus.
