Pet supplements to help treat hypothyroidism and hyperthyroidism in dogs and cats.

The endocrine system interacts with many organs and bodily systems, and the adrenal and thyroid glands plays a major role in providing critical trace nutrient support to all glands and tissue, and the adrenals can become stressed and fatigued, also affecting the liver, duodenum, and kidneys, requiring a nutritional correction.

The thyroid gland consists of two small lobes shaped like butterflies with one each side of the windpipe (trachea) located in the neck. This gland produces thyroid hormones, thyroxine (T4) and triiodothyronine (T3). The primary function of these hormones regulates and maintains your pet’s metabolic rate which in turn affects their overall health and wellness. 

Another hormone called the thyroid stimulating hormone (TSH) is produced by the pituitary gland and controls the production of the thyroid hormones. If the thyroid does not function properly, it will likely show negatively in your pet’s body weight, heart rate, skin and coat, digestive and reproductive health.

There are two types of thyroid disorders: hypothyroidism and hyperthyroidism:

Hypothyroidism

Hypothyroidism mostly affects dogs and occasionally occurs in cats. When hypothyroidism occurs, the thyroid gland is considered under active because insufficient thyroid hormones are produced. The animal body slows down with hypothyroidism. The exact cause of hypothyroidism is unknown but it may be caused by an auto-immune response in which a dog's or cat's immune system kills thyroid cell glands. Dogs that usually suffer from recurring skin problems have hypothyroidism.

The common symptoms and signs of hypothyroidism include:

Weight gain

Obesity

Lethargy

Low energy levels

Dry skin or hair loss

Constipation

Slow heart rate

Anemia

Intolerance to cold

High blood cholesterol

Infertility

Seizures

Close

Behavioral changes

Anxiety

Depression

Hperactivity

Unfocused behavior

Passive behavior 

Certain dog breeds seem to be more predisposed to hypothyroidism than others. This disorder typically affects mid to large size breeds such as Dobermans, Golden Retrievers, Dachshunds, Miniature Schnauzers, Cocker Spaniels and Airedale Terriers.

Hypothyroidism usually develops in dogs between the ages of 4 and 10 years old. Female unspayed dogs tend to be affected more, although it occurs in both males and females. There is no cure for hypothyroidism but with supplements and treatment, pets can continue to enjoy good quality of life.

The diagnosis of a hypothyroidism is based on the symptoms, thorough physical examination and review of your pet’s medical history. Certain tests such as a Baseline T4 Test, Baseline T3 Test, or TSH Stimulation Test will be performed if hypothyroidism is suspected. Your vet will choose the test most suited for your dog’s symptoms. Generally, the TSH Stimulation Test will reveal whether your dog has a low T4 or T3 level.

Hyperthyroidism

Hyperthyroidism is an endocrine disorder that commonly affects animals. The thyroid is a gland that consists of two small lobes shaped like butterflies with one each side of the windpipe (trachea) located in the neck.

When hyperthyroidism occurs, the thyroid gland is overactive and produces too much thyroid hormones, speeding up metabolism. As a result, excess cortisol builds in the blood for an extended period of time. In normal amounts, cortisol helps the body perform a number of important functions including converting fat into energy, maintaining immune system function, and responding to stress. In excess, cortisol becomes destructive.

The thyroid produces hormones, including thyroxine (T4) and triiodothyronine (T3). The primary function of these hormones is to regulate and maintain your pet’s metabolic rate, which in turn affects their overall health and wellbeing. Another hormone called thyroid stimulating hormone (TSH) which is produced by the pituitary gland, controls the production of the thyroid hormones.

When the thyroid gland is overactive, several parts of the body may not function properly, and your pet may experience drastic weight loss, appetite increase, an elevated heart rate, increased activity or poor skin and coat condition.

Hyperthyroidism typically affects middle-aged to old cats (between 4 and 22 years of age). Hyperthyroidism in dogs is rare. It is caused by a benign increase in the number of thyroid cells produced but immunological, environmental and nutritional factors may also contribute to this disorder.

Behavioral changes may also occur and include anxiety, nervousness, restlessness, depression, hypersensitivity and hyperactivity, stress as well as being unfocused or passive.

The common symptoms and signs of hyperthyroidism include:

Weight loss even with an increased appetite

Diarrhea

Vomiting

Intolerance to heat

Dull, dry or oily coat with excessive shedding

Rapid/fast breathing

Increased water consumption accompanied by urination

Increased or decreased activity

Tremors

Helpful suggestions:

Feed your pet a natural or raw and well balanced diet that contains all the essential vitamins, minerals and nutrients, free of corn, wheat and soy, preservatives, colorants and inferior protein source. 

Ensure that your pet gets regular exercise.

Boost your dog or cat’s immune system with natural immune-boosting supplements.

Take your pet to the vet for annual check-ups and monitor any abnormal physical and behavioral changes.

If your pet suffers from a thyroid problem, become your pet's health advocate by becoming as knowledgeable as possible about this health problem and by keeping a health journal to better share changes and updates with your veterinaian.

Conventional Remedies:

The diagnosis of a thyroid problem is based on the symptoms, thorough physical examination and review of your pet’s medical history. Certain tests such as a Baseline T4 Test, Baseline T3 Test, or TSH Stimulation Test will be performed if hypothyroidism is suspected. Your vet will choose the test most suited for your dog’s symptoms.

Generally, the TSH Stimulation Test will reveal whether your dog has a low T4 or T3 level. If hyperthyroidism is suspected, the diagnosis is based on the symptoms presented, enlarged thyroid gland (large enough that it can be felt), and high T4 levels.

Tests such as a CBC, serum chemistry, and urinalysis are performed if symptoms of other diseases such as kidney failure, liver disease, diabetes mellitus or heart disease are present with hyperthyroidism. In addition, tests such as the T3 suppression test, measurement of free T4 and thyrotropin-releasing hormone stimulation test may also be performed to confirm the diagnosis of hyperthyroidism.

Your vet may recommend the following standard treatments for hyperthyroidism in felines and these include radioactive iodine (I-131), anti-thyroid medication such as methimazole (tapazole) or surgery (thyroidectomy). These treatments have some adverse side effects such as liver damage, anemia, hair loss and lethargy, and cats with this problem should be kept away from pregnant women and children.

Treatment of hypothyroidism in dogs involves a daily dose of synthetic T4 hormone known as thyroxine (levothyroxine). Thereafter, follow-up blood tests will be taken in about six weeks to ascertain whether there is any improvement. This is life-long therapy but dogs usually go on to enjoy good health for the rest of their lives.
