What this trial studies

This study investigates the effects of a ketogenic diet compared to a Mediterranean diet in patients diagnosed with acromegaly due to a pituitary adenoma. Acromegaly is characterized by excessive growth hormone production, leading to various health complications. The trial aims to assess whether dietary interventions can help normalize growth hormone and IGF-1 levels, potentially improving patient outcomes. Participants will be monitored for changes in metabolic parameters and overall quality of life.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with diagnosed acromegaly and elevated IGF-I levels due to a pituitary tumor.

Not a fit: Patients who are pregnant, breastfeeding, or have undergone recent pituitary surgery or radiotherapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide a novel dietary management strategy to improve health outcomes for patients with acromegaly.

How similar studies have performed: While dietary interventions in acromegaly are less commonly explored, preliminary studies suggest potential benefits, indicating this approach may be novel.
