Pathophysiology. Rupture of the membranes is the most common cause of oligohydramnios.

Paraneoplastic autonomic neuropathy; Hereditary causes: eg, Anderson-Fabry disease, Tangier disease, multiple endocrine neoplasia (type 2b). Idiopathic causes: chronic idiopathic anhidrosis. Epidemiology. In general, these can occur in men and women at any age, but the epidemiology will depend on the particular cause. Some causes are very rare.
