    It really depends on how much lactose the person consumes as to whether this results in discomforting symptoms. For people with lactose intolerance who consume excess lactose then bloating, abdominal cramping and altered bowels are common symptoms. These may last for hours to a couple of days after consuming the lactose. However if the amount of lactose consumed was very small (for example 20ml of cows milk in a cup of tea) then this is unlikely to cause any issues.
