Fructose intolerance appears when there’s a malabsorption of fructose in the intestine. Fructose is then fermented by the gut flora and gas and other chemical harmful substances are created.
The most common symptoms are bloating and gas, tummy aches, and eventually, in the acute cases, diarrhea or constipation, heartburn, nausea and vomiting.
There is a respiratory test for diagnose of this intolerance, here you can find more information. 
If the result is positive, then it would be needed to avoid all the fructose-rich food: fruits, some vegetables, grains and sugars. In any case, the sensitivity is different for every person, and it can change depending on the days: stress, fatigue, etc.
Fructose intolerance use to be together with lactose and sucrose intolerance. So it’s better to test for these intolerances too when there’s a known fructose intolerance.
