Hopefully, he's just weak from an illness like food poisoning or the flu. I'd be more concerned about his health if he fainted for no apparent reason because it could indicate a serious underlying health issue (clogged arteries, brain tumor,...).

He did lose consciousness. If that podium hadn't been there he would have fallen flat on his face.

Fish is one of the most common dishes to receive food poisoning from, and the US troops in Iraq are eating a lot of fish and shellfish. If it is left in the sun just a little too long it spoils and no amount of preparation in the kitchen can prevent you from getting sick. Fortunately, its ill effects are usually short lived.
