Sen. Frank Lautenberg (D-N.J.) was diagnosed Tuesday with a bleeding ulcer, one day after suffering a fall that sent him to the hospital.

“Early this morning doctors diagnosed Senator Lautenberg with a bleeding ulcer, and he underwent a successful endoscopy procedure to treat it,” Lautenberg’s spokesman Caley Gray said in a statement.

Gray said Lautenberg, 86, was taken by ambulance to an undisclosed hospital Monday “after becoming lightheaded and taking a fall as a result of the condition.” Several news outlets are reporting that Lautenberg fell at his home in Cliffside Park, N.J.

Lautenberg was part of a Congressional delegation that traveled to Haiti last week. He will likely use the Congressional recess to recover from his procedure, Gray said.

“The Senator is expected to make a full recovery and will be back to work soon,” Gray said.
