hello i am extremely thirsty and constipated. i am swelling up and its making tired. besides being tired, ive have these symptoms everyday and have felt them for quite a while as i can drink about 3 gallons of h20 a day. i have been checked and i do not have diabetes insipidus or regular diabetes. i eat a very large amount of vegetables (like crazy), mostly vegetarian... but also consuming eggs, seafood, or milk with every meal. i take a multivitamin and also load up on fruit. i am about 118 5'4, and usually urinated a whole lot... but not today- just constipated.
