Fatigue the Hallmark of Low Thyroid Function

 

Published May 29, 2004 in the North Island Weekender

 

The most common complaint that any doctor sees is fatigue. The causes are numerous, but generally blood tests are done to rule out anemia, under-functioning thyroid, liver function and more. The frustrating thing is the concept of “normals” on any blood test. Normal ranges are gathered by testing random people who are not experiencing any health problems. These ranges are certainly average but may not be optimal. Medical doctors are looking for pathological changes in blood tests and if the results fall within “normal” ranges then the diagnosis may end up being depression and prescriptions for anti-depressants are filled. Naturopathic physicians are looking for levels which indicate optimal functioning of the organ system. Clinical experience shows, for example, that optimal thyroid tests values are: free T4 levels  15-19pmol/L, and TSH levels .9-2.0mU/L.

The first step is determining your results of these blood tests. Even if these values may be “optimal”, a person may have all the symptoms of being low thyroid: chilly all the time, constipation, hair falling out, changes in their voice and dry skin. For years people can experience these symptoms before the doctor sees the blood test values they are looking for and treat the thyroid.

Measuring your body temperature can give you a clue of your basal metabolic rate. Taking your body temperature mid day for 10 days the average should be 98-98.6 F (36.5-37 degrees Celsius) indicating that the thyroid has kicked in raising your basic metabolic rate. If the temperatures are consistently low and you have the above symptoms thyroid support may help you. Low temperatures may also be due to toxicity and low adrenal function which your naturopathic physician can help differentiate.

To treat the thyroid there are herbal remedies to try before resorting to thyroid hormones. Often by supporting the liver and the adrenal glands the stress on the thyroid is alleviated. Certain foods may aggravate the thyroid: soy and the cruciferous vegetables which include: brussel sprouts, cauliflower, cabbage and broccoli. These latter foods when eaten raw may lower thyroid function but when lightly steamed are fine. Soy should always be organic and non-genetically modified (GMO) however it too can slow the function of the thyroid in some people with under-active thyroid conditions.


Jane, aged 55, came to me with increasing fatigue, depression and irritability. Her TSH was in the high twenties much elevated and her salivary hormone test indicated that she was low on progesterone. She had been consuming a lot of soy to help with her menopausal hot flushes. I gave her a naturopathic thyroid remedy “BMR”, a herbal remedy  “Vitality Formula” to help with her menopausal symptoms and bio-identical progesterone cream. I also gave her my traditional Basic Treatment Guidelines. Within three months her TSH was down to 4.0 and she was feeling better in every way. I reminded her to avoid the cruciferous family of foods as well as to exercise. I monitored her TSH until it was within .9-2.0mU/L range then I decreased the BMR and she continues to do fine with her other therapies.

 

Exercise is key in raising the basal metabolic rate of the body naturally. This will stimulate the thyroid and help raise the body temperature. Following hot showers with cold also improves circulation. Eating foods with iodine in them will help the thyroid. These include seaweeds such as found in sushi and kelp powders which can be sprinkled on soups etc. Kelp is not only high in iodine but also other trace minerals. Essential fatty acids such as found in flax and fish oil are crucial for the thyroid as well as are calcium and magnesium.

 

If you are fatigued and want to feel fantastic consider a naturopathic approach to thyroid evaluation and care.
