For the fourth time in recent months, Hillary Clinton was forced to halt the speech she was giving after being afflicted with a severe coughing fit. 

Hillary Clinton has been constantly prone to coughing fits on the campaign trail, and she was hit by another one Saturday in Ohio.

“Yeah, I could use some water,” Clinton said, as she once again started hacking away during a speech. “Water would be good. I’ve been talking for days.”

Sen. Sherrod Brown (D., Ohio) was kind enough to provide her with a glass.

“Full-service senator,” Clinton said, as the crowd cheered.

So what could be wrong with her? One ears, nose, and throat specialist speculates that it's acid reflux:

“It's not just cough,” the doctor said. “There's some hoarseness, there some throat clearing, in fact there's frequent throat clearing. When you have these trio of symptoms, you have to think of what I call throat burn reflux, which is acid reflux affecting the throat.”

Dr. Aviv says the former Secretary of State might have made a mistake by reaching for those lozenges.

If you're caught in an attack of acid reflux and can't stop coughing, the doctor tells us a lozenge is not the best way to go. There's actually a breathing technique that he says will shut off the cough like a light switch.

Acid reflux is a sympton of ulcers, which is debilitating but hardly a disqualifier for the presidency. Still, there is an extraordinary lack of curiousity in the mainstream press over these constant coughing fits. In fact, while some mainstream media outlets dutifully report the interruptions, there is zero speculation about what is causing them, and no interest in investigating what might be a health issue that the campaign is keeping from the voters.

If she's elected, Clinton would be 69 years old when she takes the oath next January. While a person's health at that age depends on diet, exercise, and lifestyle choices, even the fittest septuagenarian can be afflicted with a serious disease. Clinton is having trust issues as it is. Can she be relied on to come clean if she is suffering from a serious malady?
