Lech Walesa, the anti—communist dissident who founded Solidarity in Poland, has been hospitalized in his hometown of Gdansk with a fever and gastric ailments.

Officials described his condition on Thursday as stable and said it was already improving after he admitted himself to the hospital on Wednesday. TVN24 showed Walesa in a wheelchair speaking to reporters in a hoarse voice, saying he had gastric problems.

But he also joked about not liking the hospital and not wanting his wife to see him in a weakened state.

The former Polish president had not been feeling well since returning on Monday from a trip to Tallinn, Estonia, his office said.

Lawmaker Jerzy Borowczak, a friend of Mr. Walesa’s, said on TVN24 television that Mr. Walesa had a fever of 39 degrees Celsius (102 F) when he was admitted to the hospital and was suffered from pain in his abdomen.

But Mr. Walesa’s son, Jaroslaw, told The Associated Press on Thursday that his father’s condition was good and that his temperature had already gone down.

“We are waiting for information on the results from the tests,” Jaroslaw Walesa said from Strasbourg, where is member of the European Parliament.

The deputy director of the hospital, Tadeusz Jedrzejczyk, said Mr. Walesa was in stable condition and he believed that the hospitalization would not be long.

Photographs of the 67—year—old Mr. Walesa posted on his blog on Wednesday night showed him standing in the hospital with nurses and doctors and lying in bed and shaking a doctor’s hand.

In 2008, U.S. surgeons fitted Mr. Walesa with a pacemaker in hopes of sparing him a heart transplant operation.

Mr. Walesa still travels the world giving frequent lectures on Poland’s peaceful political transition to democracy. Last month, he travelled to Tunisia to meet interim authorities and pro—democracy groups and share with them Poland’s experiences during its political and economic transformation.

Solidarity was a national freedom movement under Mr. Walesa’s leadership in the 1980s that helped peacefully bring down communism in Poland in 1989. His courage in defying communist authorities earned him the 1983 Nobel peace prize.

From 1990 to 1995, he served as Poland’s first popularly elected president in the post—communist era.
