my 11 year old son mentioned during dinner tonight that he still gets a fainting feeling when he pees - and that it is now happening throughout his pee ( not just at the end or at the beginning). Could this be caused by dehydration.....he doesn t drink much ....or is this something he should go to his doctor to have test done...?
Hi, your explanation of the problem is suggestive of Vasovagal syncope in the form of Micturition syncope. It is not so uncommon problem seen in some adolescent and more commonly in adults. This could be due to neuronal excitation which is triggered by urination. Or it could be due to any underlying cardiac disease like a structural heart disease or any arterial block. So, get an ECG and Echocardiography with Doppler of large vessels done to rule out any abnormality. Usually, a CT scan head is also prescribed to rule out brain disorder. These syncope are sometimes are preceded by some auras in form of lightheadedness, nausea, black out or headache. When these appear, the child can abort this attack by clenching of fist, grinding of teeth, tightening of thigh muscles. And after every episode, some amount of sleep should be given. Thanks and regards.
