The thyroid is a gland located in the neck that produces hormones, regulates your metabolism, and affects the function of each organ in the body.  An Overactive Thyroid Gland is referred to as Hyperthyroidism.  When the gland is overactive it produces an excessive amount of thyroxine, the hormone that regulates the body’s metabolism.  The body begins to work faster than it needs to, disrupting several bodily functions.  Hyperthyroidism can lead to other health issues such as heart complications, unnecessary weight loss, eye problems, brittle bones (Osteoporosis) or a Thyroid Storm, which is a severe condition.

The signs and symptoms associated with Hyperthyroidism can vary like most conditions.  Some of the symptoms associated with Hyperthyroidism can often imitate signs of other health issues.  People can experience symptoms that range from simple traits to extreme characteristics.  It’s always best to diagnose Hyperthyroidism, as opposed to determining whether or not you’re experiencing the condition.  Hyperthyroidism can occur at any age, but children rarely experience the condition.

• Enlarged Thyroid (Goiter or Thyroid Nodules)
• Random weight loss (that’s not contributed by any diet changes)
• Fatigue
• Muscle weakness
• Irregular heartbeat
• Nervousness or Anxiety
• Nerves Tremors
• Issues sleeping
• Irritability or mood swings
• Hair Loss or change in texture
• Skin issues (dryness, thinning, itchiness)
• Excessive sweating
• Body Temperature fluctuations
• Sensitivity to heat
• Irregular bowel movements (diarrhea)
• Increased appetite
• Irregular menstrual cycle (for women)
• Exophthalmos (protruding of the eyes)

Hyperthyroidism is caused by the excessive amounts of thyroxine and triiodothyronine, hormones produced by the thyroid.  These two hormones control most of the main body functions.  The overproduction of the hormones is commonly caused by the autoimmune disease Graves’ Disease, in which your immune system that attacks the thyroid gland.  Other causes of Hyperthyroidism are related to existing health conditions or factors that contribute to the overproduction.

• Graves’ Diseases (autoimmune disease)
• Eating foods that are high in iodine (fish, dairy products, Iodized salt, etc.)
• Unbalanced diets (nutrient deficiencies can provoke irregular activities of the Thyroid Gland)
• Supplements that contain Iodine
• Medication (Amiodarone is an example of one)
• Hormonal issues
• Postpartum (after childbirth hormonal issues like Hyperthyroidism can occur)
• Thyroid Goiter or Nodule (the adenoma part of the gland that walls itself from the rest of the Thyroid, forming a benign lump or cyst)
• Thyroditis (inflammation of the gland, caused by antibodies that damage the thyroid, viral or bacteria infection, childbirth and other unknown reasons)

• Increasing the amount of protein in the diet can help nourish the gland into functioning properly.  Protein is vital to any diet and also helps to carry the thyroid hormone to the tissues of the body.  Foods that are high in protein include almonds, broccoli, spinach, pumpkin seeds, sunflower seeds, Swiss chard, snow peas, and much more.
• Decreasing the amount of stress in your life helps improve your overall wellbeing.  When you’re stressed, it causes your immune system to change almost instantly.  The thyroid gland is very sensitive to stress.  Keeping your stress levels down helps the thyroid carry out its normal function. 
• Mercury is a chemical element found in rocks that contaminates the air and water.  This particular element is also present in numerous foods such as fish, high-fructose corn syrup and rice.  Mercury interferes with a variety of the minerals that are essential to the thyroid gland and the production of the hormone.  It’s also commonly used for dental fillings, in which a high amount is used to correct cavities.  Removing the silver fillings (amalgam) helps to decrease the amount of mercury present in the body, in addition to rationing out the amount of foods that contain high amounts of the element.
• Decreasing the amount of radiation around you is a relief to the thyroid.  Radiation is everywhere and in a lot of the things we use daily.  Things that give off the most radiation are x-ray machines, airport scanners, cell phones, tobacco, microwaves, laptops and more.  It’s a random colorless and odorless toxic gas present in numerous areas of the world.
• The use of magnets helps stimulate the thyroid gland.  It helps reduce the inflammation.

• Berries (strawberries, blueberries, blackberries etc.)
• Cruciferous Vegetables (broccoli, cauliflower, kale, cabbage)
• Sea Vegetables (kelp, dulse, agar, seaweed, nori, spirulina, Irish moss)
