The thyroid gland is the cause secrete hormones into the bloodstream to regulate the body’s metabolism including growth and metabolism. The most important in this process is the hormone thyroxine or T4 and T3. Your balance is necessary to keep the body functioning properly.
Where is the thyroid? In the cat gland it is divided into two parts, one on each side of the larynx.
Hyperthyroidism occurs when the thyroid is overactive, producing more T3 and T4. It is the most common hormonal condition affecting mostly the cat population in senior cats (cats older than 8 years).
What causes hormonal change? The official reason is not known, but hypothyroidism is associated with the development of a tumor can be benign (adenoma) or malignant. These adhere to the thyroid. They are not visible from the outside but can be felt around her throat.
Symptoms of hypothyroidism: The cat may have some of the following symptoms, but does not have to have all to achieve a diagnosis.
Some symptoms are based on food and visits to the litter box; • Weight loss despite eating food; • Excessive hunger; • insatiable thirst • Increased urination
Others are categorized as behavioral changes; • Shown restless and playful, with more energy; • Mew constantly; • The bathroom becomes excessive, including clean while lost pieces with hair; • the opposite may also occur, stop bathing and hair becomes dull and greasy; • heart rate is very high. Its normal rate should be between 120 and 140 beats per minute.
Diagnosis: Other diseases such as diabetes and chronic renal failure (CRF) have similar symptoms so it is necessary that the veterinarian routine and take samples to detect specific levels of T3 and T4 blood.
lethal disease: If untreated hypothyroidism affects the heart and kidneys. It also takes the cat to suffer from high blood pressure that results in the loss of sight.
Treatment: There are three options for treating the disease. All depend on pre-existing conditions in the cat besides money.
• oral medicine: to lower hormone production. This should be administered for the rest of your life. It does not eliminate the condition, only possession. It comes in two alternatives, by mouth (you know it’s not easy) or absorbed through the skin inside the ear.
Note that although it sounds cheap and easy to implement, in the long run it may be more expensive than other alternatives besides your cat may suffer from side effects such as vomiting and anorexia.
• Surgery: This tumor is removed with care not to remove the entire gland as this results in more damage to the kidneys and heart. If you need to remove both glands have to give daily hormone supplements.
The biggest risk is not so much the surgery, but anesthesia and health of other organs. If the condition has greatly affected the kidneys, surgery may weaken further.
• radioactive iodine treatment: The most expensive treatment but which brings greater benefits. This is an injection radioiodine injected into the minino destroying harmful thyroid tissue leaving the rest of the intact gland. No problems with other organs and the cat does not have to go through the trauma of anesthesia.
The downside, besides the price, is that the process is achieved in specialized veterinary offices and once the cat is injected radioactive so it has to stay in place for one to three weeks to remove all hazardous material.
