A San Diego, California woman shared her progress with Scripps station KGTV after going through a weight-loss procedure that involves swallowing a pill that turns into a balloon.
It's called Obalon and is manufactured by a company in San Diego.
A doctor that performs the Obalon procedure said a patient could lose 30 pounds in three to four months.
Two months after undergoing the procedure, Ora Herrera said said it's been well worth the nearly $4,000 price tag.

"I feel great," said Herrera.
Herrera is now 16.5 pounds lighter, and she said she's noticed a big difference.
"Just the sheer fact that when you lose weight, you feel lighter with more energy," said Herrera.
Obalon is a pill that a patient swallows. It then turns into a balloon in the patient's stomach to take up space so he or she is not hungry.
Herrera started with one balloon, and then swallowed another one.
Herrera said she feels satisfied and not overly full. She told KGTV that the biggest key to her success is the app that comes along with Obalon at the Obesity Control Center.
"If you put in an option of food that maybe wasn't that great, it will say maybe you can eat this and not that next time," said Herrera.
She said the clinic's nutritionist tracks her progress on the app and can message her directly about what she's eating.
Herrera went to the Obesity Control Center in Tijuana to get the Obalon procedure done by Dr. Ariel Ortiz.
Obalon is not yet approved by the Food and Drug Administration for use in the U.S.
Herrera wants to lose another 15 pounds and is on track to do meet her goal.
