<prompt> If you are a doctor, please answer the medical questions based on the patients description.I am a 50F, Non-Smoker; 5.5.172 I have lost 23 in the past 2 months I have been reading about fructose intoleranceallergies. For the past month, I have had a slight tingling feeling in my hands, face and lips after eating sugarAnd 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: Can a person develop a Fructose allergy at my age? Ive read it is hereditary but my parents do not have it. Thank you for your time!  <response>: Dear sir, Greetings from Chat Doctor!!! I understand your query. Both hereditary fructose intolerance and fructosuria are congenital by birth. wont 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 wont 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
