=Reptiles=
Gout is a common condition in various species of captive reptiles. High-protein or poor quality protein diets, dehydration and renal disease are all thought to contribute to its development as they increase levels of uric acid. Urate crystals can precipitate in the joints, kidneys, and other internal organs.
==Examination==
There may be a history of poor husbandry, including limited access to water and the feeding of a low quality protein diet. On clinical exam, there may be swelling of the joints and the animal will normally appear painful and reluctant to move.
==Diagnosis==
The diagnosis of gout may be suspected on history and physical examination and [[Lizard and Snake Biochemistry|Biochemistry]] may show a [[Lizard_and_Snake_Biochemistry#Hyperuricaemia|hyperuricaemia]]. Sometimes [[Lizard and Snake Imaging|radiography]] is useful if calcium is deposited with the urate crystals. Biopsy of any lumps may be useful.
A definite diagnosis is the demonstration of tophi in diseased tissue.

==Therapy==
The hydration of the reptile should be improved by providing ample water and feeding moisture-laden food such as soft fruits.
If the reptile is omnivorous, levels of animal protein should be decreased. If the reptile is carnivorous, instead of decreasing levels of proetin in the diet, you should ensure that the protein fed is of a high quality.
Additionally, allopurinol can be given orally on a daily basis. This decreases the quantity of urate salts produced by the liver, but does not help to remove the crystals that have already precipitated around the joints and organs.
Pain relief can be provided using NSAIDs, but gastrointestinal side effects may be seen.
==Prevention==
Good husbandry is the best way to prevent the development of gout. Ample water, and the correct amount of high quality protein (variable according to species) should be provided for the reptile. Before the administration of any drug therapy (particularly nephrotoxic drugs) the hydration status of the animal should be checked.
