Underactive Thyroid (Hypothyroidism)
A number of modern factors have resulted in an unprecedented rate of under-functioning thyroid conditions in North America today. Foremost among the reasons are:
- Consumption of soybean oil and soy products (soy has proven thyroid suppressing properties). This is why soybeans are used so extensively in feeding livestock, as they cause reduced metabolism and more rapid weight gain. On the contrary, the lauric acid in coconut oil stimulates thyroid function. In the 1940's, farmers tried giving their livestock coconut meal as a cheap food, and found that their animals became lean rather than fatter.
- The fluoridation of water supply, toothpastes and dental treatments (fluoride displaces iodine in the body).
- The devitalization and depletion of soils due to modern chemical farming practices resulting in greatly reduced trace mineral content of our food. This has a marked negative effect on thyroid function.
Besides causing a sluggish metabolism and weight gain, an underactive thyroid leads to fatigue, dull, dry hair, poor complexion, and depressed immune function.
The thyroid gland, located in the front of the neck just above the collar bone, produces thyroid hormones. These hormones are released into the bloodstream and circulated throughout the body to produce metabolic energy.
There are two thyroid hormones, thyroxine or T4 and triiodothyronine or T3, that are released into the blood stream. T3 speeds up the body's metabolism. Most of the T3 in the blood is converted from T4. The production of T3 and T4 is regulated by another hormone called TSH (thyroid stimulating hormone) or thyrotropin. This hormone is produced in the pituitary gland. If TSH is normal, it is a possible indicator that the thyroid is working properly.
Important....
- You need to have a blood test to see what your hormone levels are.
- You should also be working with your doctor as this can be a very serious health problem.
- He may have you go on a hormone replacement therapy.
- Your doctor may prescribe Armour Thyroid if you have had problems with a synthetic therapy or, if you or your doctor prefer natural products.
Armour Thyroid is a type of hormone replacement therapy. It differs from other therapies in two important ways:
- It is a natural product - not a synthetic compound
- It provides both of the key thyroid hormones levothyroxine (T4) and L-triiodothyronine (T3).
Your doctor may prescribe Armour Thyroid if you have had problems with a synthetic therapy or, if you or your doctor prefer natural products.
The symptoms of hypothyroidism may not be detected right away as it can develop slowly. You may also experience some symptoms before your thyroid hormone levels drop below normal. Here is a list of symptoms that might be caused by low thyroid:
- Dry, thick skin
- Hair thinning
- Painful muscles and joints
- Depression
- Memory problems
- Constipation
- Heavy, irregular or prolonged menstrual periods
- Low body temperature (below 97.8°F first thing in the morning)
- Low blood pressure
- Puffy eyes and face
- Slow pulse
- Reduced libido
- Poor memory
- Fatigue
- Chronic sinus infections
- Headaches
- Sweating abnormalities
- Migraines
- Heat and/or cold intolerance
- Irritability
- Fluid retention
- Anxiety
- Panic attacks
- Frequent colds and sore throats
- Lightheadedness
- Ringing in the ears
- Decreased concentration
- Slow wound healing
- Easy bruising
- Unhealthy nails
- Acid Indigestion
- Cold hands or feet
- Inappropriate weight gain
- Hypoglycemia
- Falling asleep during the day
- Itching
- High cholesterol
- Loss of outside portion of eyebrows
It is possible that there is an underlying cause that is the reason for your hypothyroidism. Some possible causes are heavy metal poisoning (especially mercury), adrenal fatigue, food allergies and celliac disease. It might be wise to also check into what may be causing your thyroid problem and deal with it also in order to get well.
There are actually some foods that can cause low thyroid levels. They are called goitrogenic foods and include Brussels sprouts, rutabaga, turnips, cabbage, radishes, broccoli, cauliflower, millet, kale, and soy. Goitrogens are naturally occurring thyroid inhibiting substances found in these foods. The thyroid inhibiting effect of these foods are thought to be largely inactivated by cooking. So if you eat any of these foods, be sure to cook them. You should NOT eat any of these foods in large quantity even when cooked and don't eat them at all raw.
Support your thyroid - naturally and holistically
When the problem is subclinical hypothyroidism holistic support can resolve women's symptoms and prevent future problems. For women who have already progressed to thyroid disease, some find they can reduce their thyroid medication with the approval of their healthcare practitioner.
The key is to support your body's ability to make and balance all of its hormones. Here's what we recommend to our patients with thyroid symptoms:
- Dietary changes. In particular, consume foods that are naturally high in B vitamins and iodine such as whole grains, nuts, seeds, seaweed, fish and root vegetables.
- Medical-grade nutritional supplements. Choose a daily multivitamin that's bioavailable, natural and manufactured to pharmaceutical standards. We also recommend omega-3 fatty acid supplements.
- Exercise. Try for at least 30 minutes a day, four to five days per week. Finding the energy to exercise will become easier as your body starts to heal itself.
- Stress management. This is particularly important for women with severe adrenal fatigue. You can get started by learning some deep breathing techniques, or consider trying meditation.
- Phytotherapy. Women whose thyroid issues are related to perimenopause or menopause usually benefit from gentle endocrine support such as phytotherapy.
Phytotherapy is the use of plants, either in whole food form or in the form of standardized extracts and supplements, for healing purposes. Its roots trace all the way back to the beginnings of time and still stand strong in much of the world today.
Thyroid symptoms are frustrating and so is a lifetime of medication. Once you start to see your body as a group of interconnected systems you'll understand why a holistic approach can work wonders.
Drug Therapy
Brand Names:
Levothroid, Levoxyl, Synthroid, Unithroid
Uses:
Levothyroxine is used to treat an underactive thyroid (hypothyroidism). It replaces the hormone that is normally produced by the thyroid gland. Low thyroid levels can occur naturally or when the thyroid gland is injured by radiation/medications or removed by surgery. It is important to have adequate levels of thyroid hormone in your bloodstream to maintain normal mental and physical activity. In children, adequate levels of thyroid hormone are important for normal mental and physical growth and development.
This medication is used to treat other types of thyroid disorders as well (e.g., certain types of goiters, thyroid nodules, thyroiditis, thyroid cancer).
Side Effects:
Symptoms of low thyroid levels include fatigue, muscle aches, constipation, dry skin, weight gain, slow heart rate, sensitivity to cold, or dry brittle hair that tends to fall out easily. These symptoms should disappear as your body adjusts to the medication. If they persist or become bothersome, notify your doctor promptly.
Headache, nervousness, trembling, sweating, increased appetite, diarrhea, weight loss or insomnia may occur. If any of these effects persist or worsen, notify your doctor promptly.
