What is Hyperthyroidism in Cats?

Hyperthyroidism, also known as Thyrotoxicosis, is a common disease affecting middle-aged to older felines. It occurs when the two thyroid glands in a cat's neck produce excessive amounts of the thyroid hormone thyroxine (T3 and T4).

What Causes Hyperthyroidism in Cats?

The primary cause of hyperthyroidism in cats is a non-cancerous tumor called an adenoma. In rare cases, it can be due to a cancerous tumor known as thyroid adenocarcinoma. These benign growths form nodules on the thyroid lobes, leading to increased hormone production and a metabolic surge, affecting most body organs.

How Does Hyperthyroidism Affect a Cat's Body?

Excess thyroxine increases the metabolic rate, causing all body tissues to work harder and deplete vital resources like glucose, fats, and protein. This breakdown of muscle protein for fuel results in muscle loss. Vitamin stores are also depleted, leading to deficiencies, and cardiovascular and respiratory functions are impacted. Increased blood flow and stronger muscle contractions can thicken the heart's left ventricle, potentially causing heart failure if untreated.

Digestive functions are also heightened, leading to diarrhea. Despite increased hunger, weight loss occurs due to the rapid metabolism. Muscle tremors and high blood pressure (hypertension) are common complications, which can damage other organs.

Signs and Symptoms of Hyperthyroidism in Cats

Your cat may show some or all of these symptoms:

• Excessive hunger and increased appetite
• Weight loss
• Vomiting and/or diarrhea
• Increased thirst and urination
• Dull, matted, greasy coat
• Behavioral changes, nervous disposition, hyperactivity
• Muscle tremors
