 [ Symptoms ] are these symptoms indicative of dehydration  dark foul smelling urine extreme thirst itchy skin hemoglobin of 6 8 confusion hard stools [ Disease ] most helpful answer the answer is yes and no some of your symptoms could be indicative of dehydation namely dark colored urine extreme thirst itchy skin hard stools confusion but dehydration is not the only condition that could cause these symptoms i hope you are following up with a medical professional about these symptoms to determine the underlying cause regarding your hemoglobin results i wonder if you are referring to the actual hemoglobin test or if you are referring to the  hemoglobin a1c  test these are two entirely different things basically a hemoglobin test measures your red blood cell count a result of 6 8 would be quite low for either a woman or a man in fact that result would put you in the  anemic  category and it would require medical treatment on the other hand a hemoglobin a1c test provides a snapshot of your blood sugar control over the preceding three months a result of 6 8 would be considered within the desirable range for someone with diabetes it would be considered outside the normal range for someone without diagnosed diabetes i would suggest you make an appointment with your primary care provider pcp to review your symptoms get a diagnosis and come up with a treatment plan best to you
