Lactose Intolerance Sign #2: Grumbling Sounds
When your stomach is full, it releases juices containing various enzymes to break down the available food. This will sometimes produce grumbling sounds which are caused by gases that are moving through the contents of the stomach.
In the case of lactose intolerance, your stomach may be producing more gases than normal. These excess gases can cause grumbling that’s so loud it can be heard by people around you. It is not uncommon to hear your stomach grumbling when hungry, but that happens more often in people who are intolerant to lactose.
