The four "silent" killers in cats.

2. Hyperthyroidism

Hyperthyroidism is an endocrine disorder in which the thyroid gland produces too much thyroid hormone. This is observed in middle-aged geriatric cats and can lead to very similar clinical signs of chronic renal failure, including:

• Excessive thirst 
• Increased water consumption / urination 
• Vomiting/diarrhea 
• Weightloss

But as hyperthyroidism increases the metabolism of the cat, it causes a decisive sign: a voracious appetite despite weight loss. It can also lead to:

• Heart rate for heart rate 
• Severe hypertension (resulting in acute blood loss, neurological signs or even blood clots or strokes) 
• Secondary organ damage (eg, heart block or kidney changes)

Fortunately, the treatment of hyperthyroidism is very effective and includes either a drug (called methimazole, surgical removal of the thyroid (less common), or a prescription diet called y / d Feline Thyroid Health) or treatment with i111 radioactive iodine. In the case of hyperthyroidism, the earlier you treat, the fewer side effects or organic lesions in your cat.
