My 15 YO DD has had a problem with hunger for years now--it seemed to start with the onset of puberty and it's still happening. She can eat a large dinner and within 30 mins of eating it she is ravenous again. It's worst at night, just before bed time...to the point that she gets all ready for bed, then has to go downstairs and eat again, do teeth again etc etc or she will lie awake unable to sleep because of hunger. She gets to the point where she feels hungry but is sick of eating. Her stomach rumbles very loudly at school (v. embarrassing for her) and she often feels she can't concentrate on school work because she feels faint with hunger. We have been to the drs about it but the dr says she thinks her food intake is normal. She's had blood tests, urine tests etc and nothing seems to be wrong metabolically. Does this ring bells for anybody else? Any advice anyone???
