https://www.vetsurgeon.org/f/clinical-questions/29591/polycythaemia-and-addisons Hi, I have a 6yo MN french bulldog, with a history of atopy (on immunotherapy and apoquel), presented last week with polydipsia and occasional vomiting, plus regular episodes of gulping/lip smacking, for the last month or so. physical exam unremarkableen-USTelligent Community 10https://www.vetsurgeon.org/thread/227825?ContentTypeID=1Wed, 13 Jan 2021 20:25:17 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:0bb85703-f1cd-4732-8194-bf1319d9e1c8Andrew Kent<p>Hi Niamh,</p> <p>Tricky one and good idea excluding Addisons.</p> <p>In terms of the hyperkalaemia - I would likely monitor that initially and see if repeatable. We sometimes see this as a spurious reading or with sample contamination (such as with EDTA) so check first and see. If its persistent or particularly if worsening then we may need to explore further.</p> <p>The high HCT is also challenging as, whilst high, its not sky high so would also be reasonable to watch for a bit. If increasing then again we may need to investigate - if stable it could be normal for this dog.</p> <p>Andy</p><div style="clear:both;"></div>https://www.vetsurgeon.org/thread/227763?ContentTypeID=1Tue, 12 Jan 2021 16:54:11 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:b3fef3b8-6ba5-4eb7-aee6-a3523e6f16b7niamhjl<p>Hi,</p> <p>to update: the ACTH stim test on this dog has come back normal, ruling out Addisons.&nbsp;<br /><br /></p> <p>in light of this, any advice on where to go next with this would be much appreciated.&nbsp;<br /><br /></p> <p>thanks,</p> <p>Niamh</p><div style="clear:both;"></div>
