Hi, I am probs posting in the wrong area/thread etc but I have not been on a forum before so please forgive me if I popping-up where I shouldn't! Wonder if in spite of this if someone can give advice? Have 20 year old daughter, currently just finishing 2nd year of uni. She is very sporty, generally healthy but in the last 6 months has lost/is losing so much weight - currently 7stone 3lbs, is so tired all the time ie gets up, has breakfast but is then too tired to do anything else and has to go back to sleep, is white as a sheet, eating less and less, is having tingling/numbness in arms and has recently started getting up in night to go to wee, high ly unusual. We have diabetes in family, maternal great grandfather and grandmother. To cut to the chase, she had a lactase intolerance test a few days ago - I have banged on about diabetes to the GP - apparently she does not show the symptoms - anyway the results were as follows - fasting 5.1, then at every half hour for two hours were: 5.2, 5.4, 4.2 and 3.6. I understand that a larger than increase of 30mg/dl between fasting sample and any other subsequent sample is normal; less than a 20mg/dl is lactase deficient and 20-30 mg/dl is indeterminate. Can anyone help me regarding my daughter's results? Not being an expert, I cannot understand if the jump from the fasting to the third result may be an increase of 30mg/dl or not but the test I believe, could be 'abnormal' indicating a glucose tolerance test so I have learned? Help please anyone?
