What is Hypothyroidism?
Hypothyroidism happens when your thyroid gland, at the front of your neck, doesn’t produce enough thyroid hormone (underactive thyroid). There are several types of hypothyroidism. The most common is Hashimoto’s thyroiditis, an autoimmune disease where the immune system mistakenly attacks the thyroid gland. The disease affects both sexes and all ages, but is most common in women over age 50. Because the thyroid gland helps regulate your metabolism, low thyroid levels cause your body to slow down and can affect everything from appetite to body temperature. Symptoms can appear over time and can be hard to diagnose. Left untreated, hypothyroidism can cause serious health complications.
Signs and Symptoms:
- Slow pulse
- Hoarse voice, slowed speech
- Goiter (caused by swollen thyroid gland)
- Sensitivity to cold
- Weight gain
- Dry, scaly, thick, coarse hair
- Numbness in fingers or hands
- Confusion, depression, dementia
- Menstrual problems
- In children, slowed growth, delayed teething, and slow mental development
What Causes It?
There are different kinds of hypothyroidism with different causes. In Hashimoto’s thyroiditis, antibodies in the blood mistakenly attack the thyroid gland and start to destroy it. Post-therapeutic hypothyroidism occurs when treatment for hyperthyroidism leaves the thyroid unable to produce enough thyroid hormone. And hypothyroidism with goiter happens when you don’ t get enough iodine in your diet. In the developed world iodine is added to salt so goiter is rare, although it still happens in undeveloped countries.
Your health care provider will prescribe a synthetic thyroid hormone called levothyroxine (Levothroid, Synthroid, Unithroid) that you will take daily. A natural dessicated thyroid hormone drug, made from the thyroid glands of pigs, is also available by prescription. Your doctor will want to adjust your dose over a period of several weeks, after regular blood tests to check the amount of thyroid hormone in your blood.
Complementary and Alternative Therapies:
If you have hypothyroidism, you need conventional medical treatment. Nutrition and herbs can help support conventional treatment, but should not be used by themselves to treat hypothyroidism.
Nutrition and Supplements:
Following these nutritional tips may help reduce symptoms:
- Eat foods high in B-vitamins and iron, such as whole grains (if no allergy), fresh vegetables, and sea vegetables.
- Avoid foods that interfere with thyroid function, including broccoli, cabbage, brussels sprouts, cauliflower, kale, spinach, turnips, soybeans, peanuts, linseed, pine nuts, millet, cassava, and mustard greens.
- If you take thyroid hormone medication, talk to your doctor before eating soy products. There is some evidence soy may interfere with absorption of thyroid hormone.
- Taking iron supplements may interfere with the absorption of thyroid hormone medication, so ask your doctor before taking iron.
- Eat foods high in antioxidants, including fruits (such as blueberries, cherries, and tomatoes) and vegetables (such as squash and bell pepper).
- Avoid alcohol and tobacco. Talk to your doctor before increasing your caffeine intake, as caffeine impacts several conditions and medications.
Additional supplements that may also help:
- Omega-3 fatty acids, such as fish oil, to help decrease inflammation and help with immunity. Omega-3 fatty acids may increase the risk of bleeding, especially if you already take blood-thinning medication. Ask your doctor before taking omega-3 fatty acids if you take blood thinners such as warfarin (Coumadin) or if you have a bleeding disorder.
- L-tyrosine. The thyroid gland combines tyrosine and to make thyroid hormone. If you are taking prescription thyroid hormone medication, you should never take L-tyrosine without direction from your doctor. Do not take L-tyrosine if you have high blood pressure or have symptoms of mania.
- Do not take an iodine supplement unless your doctor tells you to. Iodine is only effective when hypothyroidism is caused by iodine deficiency, which is rare in the developed world. And too much iodine can actually cause hypothyroidism.
Herbs are generally a safe way to strengthen and tone the body’s systems. As with any therapy, you should work with your health care provider to get your problem diagnosed before starting any treatment. You may use herbs may as dried extracts (capsules, powders, teas), glycerites (glycerine extracts), or tinctures (alcohol extracts). People with a history of alcoholism should not take tinctures. Unless otherwise indicated, make teas with 1 tsp. herb per cup of hot water. Steep covered 5 – 10 minutes for leaf or flowers, and 10 – 20 minutes for roots. Drink 2 – 4 cups per day. You may use tinctures singly or in combination as noted.
Few herbs have been studied for treating hypothyroidism. More research is needed.
- Coleus (Coleus forskohlii), for low thyroid function.
- Guggul (Commiphora mukul, for low thyroid support.
- Bladderwrack (Fucus vesiculosus), for low thyroid support. Do not take bladderwrack unless directed by your doctor. Bladderwrack contains iodine. Although lack of iodine can cause hypothyroidism, most cases of hypothyroidism in the developed world are not caused by iodine deficiency. In fact, too much iodine can actually cause hypothyroidism. Bladderwrack may also contain toxic heavy metals.
