[Syndrome of catecholamine hypersecretion secondary to a jejuno-ileal bypass]

Hypersecretion of catecholamine primarily affecting adrenaline levels arose in a patient given a jejunoileal bypass for severe obesity. Apart from organic factors, including a hetero and/or orthotopic pheochromocytoma and the therapeutic effect of beta-blocking drugs, it is suggested that the pathogenesis of the patient's condition is based on a hypersecretion of VIP, as sometimes occurs in patients with short intestine/syndrome.
