Lactose intolerance means that you cannot break down the sugar lactose. It is caused by DNA mutations that lead to a nonfunctional lactase enzyme. Does this disorder affect your ability to digest other sugars beside lactase?
Other sugars like saccharose or maltose are hydrolised by their own specific enzymes saccharase for saccharose and maltase for maltase. Therefore, the ability to digest other sugars beside lactase won't be affected in lactose intolerance.
