Overview
The most common cause of ectopic ADH secretion is cancer. Certain lung cancers, as well as some head and neck tumors, are the most common cancers that cause this problem. In rare cases, many other tumors may cause ectopic ADH secretion.
Causes
Common Causes
- Head injury
- Cancers
- Lung cancer (especially small cell lung cancer, as well as other small-cell malignancies of other organs)
- Infections
- Drugs
- Chlorpropamide
- Cyclophosphamide
- Carbamazepine
- Selective serotonin reuptake inhibitors (SSRIs, a class of antidepressants)
- Methylenedioxymethamphetamine (MDMA, commonly called Ecstasy. SIADH due to taking ecstasy was cited as a factor in the death of Leah Betts)
