It is possible to have acid reflucx with these symptoms. You would also have some heartburn associated with this. I am more inclined to think you are producing excess abdominal gas.
Excessive production of gas by bacteria is a common cause of intermittent abdominal bloating/distention. Bacteria can produce too much gas in three ways. First, the amount of gas that bacteria produce varies from individual to individual. In other words, some individuals may have bacteria that produce more gas, either because there are more of the bacteria or because their particular bacteria are better at producing gas. Second, there may be poor digestion and absorption of foods in the small intestine, allowing more undigested food to reach the bacteria in the colon. The more undigested food the bacteria have, the more gas they produce. Examples of diseases of that involve poor digestion and absorption include lactose intolerance, pancreatic insufficiency, and celiac disease. Third, bacterial overgrowth can occur in the small intestine. Under normal conditions, the bacteria that produce gas are limited to the colon. In some medical conditions, these bacteria spread into the small intestine. When this bacterial spread occurs, food reaches the bacteria before it can be fully digested and absorbed by the small intestine. Therefore, the bacteria in the small intestine have a lot of undigested food from which to form gas. This condition in which the gas-producing bacteria move into the small intestine is called bacterial overgrowth of the small intestine (bowel).
Excessive production of gas by bacteria is usually accompanied by more flatulence. Increased flatulence may not always occur, however, since gas potentially can be eliminated in other ways-absorption into the body, utilization by other bacteria, or possibly, by elimination at night without the knowledge of the gas-passer.
