Hello, I should have posted weeks ago because I have spent a lot of time searching for answers in other posts! My son has been displaying classic symptoms for six weeks. However, all of his blood tests have come back normal. He has had a fasting test, post meal test, GTT and urine test. All normal. I believe if I could have done one of these test in the afternoon (all were done in AM), after a high carb meal, he would've had higher readings. His symptoms are always worse in the afternoon. About my sweet son: He is 6 yo and his symptoms are as follows: skinny and always hungry. He has not gained an ounce in five weeks. At a party Sat. he parked by the chip bowl and ate like he was starving. At one point he was peeing 20 times a day. Usually drinking water each time he headed to the bathroom. He has dark circles under his eyes. He gets very irritable, especially as the day goes on. The last three days he has complained about his head hurting. So, here is my issue. I have had to push at every step with the doctor. I am sure he will think I am crazy to request any more tests. Should I just wait and see if he gets worse or should I ask for a different test? Should I push to meet with an endo.? In the meantime we have him off of gluten and sugar. This definately helps the symptoms. We are probably still feeding him too many carbs. I like to think that I could stop the progression by adopting some healthier habits. I am also giving him two fish oil pills per day. Should I just wait and see? Would it be wise to catch it early? Thank you so much. I can't believe it just now occured to me that I should check with the experts after doing countless google searches.
