President Barack Obama briefly stops his speech Monday at the White House to assist a woman standing behind him, who appears to become unsteady on her feet. She was later identified as Karmel Allison, who has been diagnosed with Type 1 diabetes.

A pregnant woman has thanked President Barack Obama for catching her before she fainted as he delivered a White House speech on Monday.

San Diego resident Karmel Allison began to feel lightheaded as she stood directly behind the president at the event in the Rose Garden.

She had been invited to the White House after she wrote a blog post titled What Obamacare Feels Like to a Diabetic.

Towards the end of Obama's speech, Allison swayed and seemed to struggle to stay on her feet. Obama turned to her and supported her, saying, "I got you, you're OK."

He then quipped, "This happens when I talk too long."

The White House said Allison was diagnosed with Type 1 diabetes when she was nine years old, and has stayed on the same insurance ever since out of fear she would not be able to find a plan that would cover her due to her pre-existing condition.

She was escorted out of the event and later tweeted her thanks to the president.

I'm ok world- just got a little lightheaded.Thanks, @BarackObama for catching me! And good thing this pregnant diabetic is pregnant :) — Karmel Allison (@karmel_a) October 21, 2013

Allison's husband also chimed in with thanks of his own.

@aaronprill @karmel_a I almost bolted to the stage but thought twice about how that would look to the Secret Service. So glad she's ok. — David Allison (@david_allison) October 21, 2013
