For The Past Few Days, Eating Moderately Causes Bloating And

For the past few days, eating moderately causes bloating and some discomfort in lower left quadrant. I hear and feel gurgling from stomach. I am ideal weight. No smoking. Quit milk. Happens after wheat products though never had a problem with them. Am a 'health nut'. Could it be mild intestinal bug? Bowels regular. No vomiting.
