My 10 year old cat, Socks, has recently developed a greater appetite than normal. Despite his increased food intake, he does not seem to be gaining weight. If anything, it seems like his ribs are easier to feel. He seems to be a happy cat other than an occasional episode of vomiting which I attribute to hairballs. Are there any medical conditions which cause weight loss in spite of increased appetite? |
Weight loss in the older cat may be caused by serious conditions affecting the heart, kidneys or intestinal tract. Pets with cancer often cannot maintain their weight. These problems, however, are usually associated with a normal or decreased appetite. Diabetes and hyperthyroidism are two common conditions causing increased appetite and weight loss. Both of these conditions may be diagnosed by routine blood and urine tests. Properly treated, pets with either condition may have a long and happy life. Diabetes is caused by decreased insulin production, with a resulting increase in blood sugar levels. It is usually associated with increased water intake and urine output. Treatment usually consists of once or twice daily insulin injections. Occasionally, a diabetic cat may be controlled with oral medication. Hyperthyroidism is caused by increased production of thyroid hormone, resulting in an increased metabolic rate. Elevated thyroid levels can cause serious damage to the heart and liver. Conventional treatment options include medical and surgical therapy. A recent advance in treatment involves use of radioactive iodine to cause decreased production of thyroid hormone. Since diabetes and hyperthyroidism are so common in older cats, routine bloodwork to screen for these diseases is a good idea. Since hyperthyroidism increases anesthetic risk, we routinely run thyroid levels on older cats undergoing anesthesia. If you have any questions regarding these diseases, ask your veterinarian. |
