A 58-year-old female patient presented with a major thyroid imbalance after sleeve gastrectomy, manifesting itself in large-scale changes in thyroid stimulating hormone (TSH) levels. The transition from a tablet treatment to a liquid form alleviated burden of treatment, unfortunately without normalising TSH. Our case emphasises the importance of the understanding of hypothalamic\u2013pituitary\u2013thyroid feedback control mechanisms together with good galenic choice, management of associated conditions and the elimination of other causes of variations of TSH levels during the management of hypothyroid patients after sleeve gastrectomy.<\/jats:p>","DOI":"10.1136\/bcr-2019-230515","type":"journal-article","created":{"date-parts":[[2019,8,10]],"date-time":"2019-08-10T13:09:09Z","timestamp":1565442549000},"page":"e230515","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Major imbalance of thyroid function after laparoscopic sleeve gastrectomy"],"prefix":"10.1136","volume":"12","author":[{"given":"Laurent","family":"Brutus","sequence":"first","affiliation":[{"name":"P\u00f4le de Sant\u00e9 du Marais, Sallertaine, France"},{"name":"D\u00e9partement de m\u00e9decine g\u00e9n\u00e9rale, Universit\u00e9 de Nantes, Nantes, Pays de la Loire, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Armelle","family":"Poupard","sequence":"additional","affiliation":[{"name":"P\u00f4le de Sant\u00e9 du Marais, Sallertaine, France"},{"name":"D\u00e9partement de m\u00e9decine g\u00e9n\u00e9rale, Universit\u00e9 de Nantes, Nantes, Pays de la Loire, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cl\u00e9ment","family":"Le Glatin","sequence":"additional","affiliation":[{"name":"P\u00f4le de Sant\u00e9 du Marais, Sallertaine, France"},{"name":"D\u00e9partement de m\u00e9decine g\u00e9n\u00e9rale, Universit\u00e9 de Nantes, Nantes, Pays de la Loire, France"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2019,8,10]]},"reference":[{"key":"2025082701505350000_12.8.e230515.1","first-page":"445","article-title":"Incidence assessment of benign thyroid diseases in the SU","volume":"41","author":"Estaquio","year":"2009","journal-title":"VI.MAX study, 1994-2002.
