Chantix &Thyroid: Is There a Connection?

Does Smoking, Quitting Smoking, or Chantix throw you into Thyroid Problems?

Smoke free 205 Days!

As a lot of you know that follow my blog regularly, I had a comment by Joan that her and her twin sister had major side effects with Chantx involving their Thyroid. That prompted me to have mine checked. I went to the Doctor and had the blood work done and everything else checked while I was there. The nurse called yesterday with the results. I have HYPOTHYROIDISM and have to take a medication called Synthroid for the rest of my life! Don’t you think that is quite a coincidence? Well, I sure do. Actually, what are the odds that someone on the internet tells me about this new side effect of Chantix that I had not heard “scary stories” about and it turns out I have it too. Very strange in deed. So I decided to check this out for myself and here is what I have found out.

Does smoking cigarettes increase the odds of getting Hypothyroidism? That was my first question. Yes it does.

Smoking and Thyroid Diseases: The Connection

Smoking has been found to be one of the prominent causes of hypothyroidism and it has also been clear that smoke contains harmful ingredients that retard the functioning process of the thyroid gland. Many substances present in smoke trigger off anti-thyroid action inside the system and one among them is cyanide. On smoking cigarettes and other tobacco containing products, the ingredient cyanide enters the system and forms a specific compound thiocyanate.This new substance thiocyanate significantly prevents iodine intake and ensures the low production of thyroid hormones (hypothyroidism).

However, clinical studies have established that smokers are more prone to have thyroid enlargement which could be an indication of thyroid disturbance. Further, it has also been found that grave’s disease (thyroid eye disease) which is specifically responsible for hyperthyroidism can be triggered off on account of smoking. An article appeared in the Journal of the American Medical Association which makes it clear that people who are addicted to smoking are twice more likely to develop grave disease in comparison to non-smokers.

In a study involving women in Switzerland, Italy, the Netherlands and Sweden, it was found that smoking impairs both thyroid hormone secretion and thyroid hormone action, according to Beat Mueller, M.D., et al., in the October 12, 1995 issue of The New England Journal of Medicine.

Before I go blaming Chantix, there is a connection between Hypothyroid and smokers. Smoking is directly related to Hypothyroid so how can anyone say Chantix did this to me when it could have been building over many years and smoking has masked it. We all know smoking and nicotine increase your metabolism so the weight gain doesn’t show up as a symptom. Then we quit smoking and Pow! We get this weight gain that cannot be removed by diet and exercise, and we are fatiqued, almost lethargic when we quit because we all know nicotine is an upper/stimulant. So we are diagnosed with Hypothyroid and we want to blame somebody and Chantix is right there. They do have the warning that rarely it can cause the problem so we know that is a possibility, but not very likely. I would tend to believe that this is another thing that smoking has caused, just like osteoporosis, and I just have to learn to live with it.

How to Tell If You Are Hypothyroid

Here’s how you can determine if you have an underactive thyroid condition called hypothyroidism.

Difficulty Level: Easy Time Required: 5 minutes

Here’s How:

1. List your risk factors, including: family history, previous treated/untreated problems (nodules, hyperthyroidism, goiter, hypothyroidism, thyroid cancer), previous thyroid surgery, another autoimmune disease, childbirth.
2. Note symptoms including:

  • weight gain, depression, forgetfulness, fatigue, hoarseness, high cholesterol, constipation, feeling cold, hair loss, dry skin, low sex drive, tingling hands/feet, irregular periods, infertility.
  • 3. Note related conditions, including: recurrent pregnancy loss, resistant high cholesterol, difficult menopause, fibromyalgia, chronic fatigue syndrome, carpal tunnel syndrome, mitral valve prolapse.
    4. Meet with your doctor for a thyroid examination and blood test.
    5. Request a TSH (thyroid stimulating hormone) blood test, along with T4, T3, Free T4 and Free T3 tests.
    6. Review your test results with the doctor.
    7. At most labs in the U.S., up until late 2002, the normal range is from around 0.5 to 5.5. That range changed to .3 to 3 as of early 2003. If the TSH level is at the higher end of the range, or above the range, your doctor may determine that you are hypothyroid (underactive thyroid.)
    8. If your doctor ran a test called Total T4 or Total Thyroxine, normal range is approximately 4.5 to 12.5. If you had a low reading, and a high TSH, your doctor might consider that indicative of hypothyroidism.
    9. If your doctor ran a test called Total T4 or Total Thyroxine, normal range is approximately 4.5 to 12.5. If you had a low reading, and a low TSH, your doctor might look into a possible pituitary problem.
    10. If your doctor ran a test called Free T4, or Free Thyroxine, normal range is approximately 0.7 to 2.0. If your result was less than 0.7, your doctor might consider that indicative of hypothyroidism.
    11. If your doctor ran a test called Total T3, normal range is approximately 80 to 220. If your result was less than 80, your doctor might consider that indicative of hypothyroidism.
    12. If your doctor ran a test called Free T3, the normal range is approximately 2.3 to 4.2. If your result was less than 2.3, your doctor might consider that indicative of hypothyroidism.
    13. If your test results come back “normal” but you have many of the symptoms or risk factors for thyroid disease, make sure you ask for an antibodies test. Some doctors believe in treating thyroid symptoms in the presence of elevated antibodies and normal TSH levels.
    14. If your test results come back “normal” but you have many of the symptoms or risk factors for thyroid disease, consider going to a reputable holistic M.D. or alternative physician for further interpretation and diagnosis.

    Tips:

    1. Many people who have radioactive iodine treatment for hyperthyroidism/Graves’ Disease, or who have sugery to remove all or part of the thyroid due to nodules or cancer, are hypothyroid.
    2. If you have been treated with radioactive iodine or surgery, and are currently not on thyroid hormone replacement, but have hypothyroidism symptoms, see your doctor.
    3. Keep in mind that laboratory normal values vary somewhat from lab to lab. Make sure you find out your lab’s normal ranges and review these with your doctor.
