Claims
- *[Paraphrased derived summary — non-Open-Access source.]* X-rays often show mineralized or radiolucent tophi in organs and joints (as seen in gout).
- *[Paraphrased derived summary — non-Open-Access source.]* Primary visceral gout is urate crystal deposition in organs from chronic hyperuricemia, usually excess dietary protein.
- *[Paraphrased derived summary — non-Open-Access source.]* Correcting the diet treats primary visceral gout.
- *[Paraphrased derived summary — non-Open-Access source.]* Among reptile metabolic bone diseases, nutritional secondary hyperparathyroidism is the most common.
- *[Paraphrased derived summary — non-Open-Access source.]* It stems from poor diet (low calcium-to-phosphorus ratio, vitamin D3 lack) or poor husbandry (no UVB, insufficient heat).
- *[Paraphrased derived summary — non-Open-Access source.]* Affected animals are usually fast-growing herbivorous or insectivorous lizards and turtles.
- *[Paraphrased derived summary — non-Open-Access source.]* Late-stage findings include hyperphosphatemia and low total and ionized calcium.
- *[Paraphrased derived summary — non-Open-Access source.]* Critical cases need fluid therapy, nutritional support, parenteral calcium if hypocalcemic, and phosphate binders if hyperphosphatemic.
- *[Paraphrased derived summary — non-Open-Access source.]* Correcting diet and husbandry is the mainstay of successful treatment, with a favorable prognosis especially if the animal is still eating.
