MANILA, Philippines - Former President and now Pampanga Representative Gloria Macapagal-Arroyo said Tuesday she was thankful to her doctors at the Veterans Memorial Medical Center for recognizing her right to seek stem cell treatment for her medical condition.

In her Twitter account (@gmarroyo), Arroyo said, "I'm glad my Veterans attending physicians recognize my right to seek alternative treatment and don't consider it in conflict with the conventional treatment they're giving me."

Arroyo on Monday underwent her fourth stem cell intravenous treatment while still attending her weekly therapy at the VMMC.

"Procedure was not only intravenous injection of the stem cell material but also other naturalist treatment therapies," she said in her Twitter account.

"It has to be done under very hygienic conditions. Then I proceeded to my 3x (three times) weekly physical therapy at Veterans," she added.

Earlier, she said her treatment would involve cultured stem cells, which would be "much more modest in price that the one coming from sheep or one's own body."

Stem cell therapy involves the use of fresh cells injected into the body to regenerate cells to reverse aging or treat illnesses.

Arroyo has been complaining of choking sensation because of the "aggressive protrusion" of the titanium plate that was earlier implanted on her in a surgery. Her physician, Dr. Roberto Anastacio, said that the protrusion is slowly blocking her air and food passages.
