I am a 50F, Non-Smoker; 5.5.172# (I have lost 23# in the past 2 months)  I have been reading about fructose intolerance/allergies.  For the past month, I have had a slight tingling feeling in my hands, face and lips after eating sugar~And occasionally after a meal that doesnt contain overt sugars.  It is fleeting (5-10 mins) but alarming as it also causes a bit of a vertigo-like symptom (very slight). I am not sure if the vertigo sx is related to a small amount of panic I have over the other sxs. My question is
Dear sir, Greetings from Chat Doctor!!! I understand your query. Both hereditary fructose intolerance and fructosuria are congenital / by birth. won't manifest in mid-age. Fructosuria is mild and harmless condition, only finding is that fructose is seen in the urine. HF is very dangerous baby won't survive usually die of liver failure. Only chance you might have fructosuria get the urine fructose levels, Thank s for contacting us, do contact us for more queries
