If you’re getting your TSH levels checked to monitor your thyroid health, it’s best to get that done in the morning. Otherwise, your results may come back normal even though you have hypothyroidism.
All the body’s hormones follow a daily rhythm, including thyroid hormone. This means there are times of the day when it naturally higher or lower. Researchers tested the blood of hypothyroid subjects both before 8 a.m. and again between 2 and 4 p.m.
In hypothyroid patients both untreated and on thyroid medication, TSH dropped was substantially lower during the afternoon test. This means an estimated 50 percent of people with hypothyroidism are not being diagnosed.
In the untreated group, TSH was 5.83 in the morning and 3.79 in the afternoon. In the treated group, TSH was 3.27 in the morning and 2.18 in the afternoon.
A 2004 study also showed late morning, non-fasting TSH was 26 percent lower compared to the early morning, fasting TSH. This means even a late morning blood draw could result in a failure to diagnose. Do you really want to know what is going on with your thyroid? Schedule a FREE 15-Minute Consultation with Dr. Celaya.
TSH blood test timing and functional medicine ranges
The timing of your blood draw plays an important role in reading a thyroid panel. However, there is more to it.
Even with an early morning blood draw, many doctors will still fail to diagnose hypothyroidism because they use lab ranges that are too wide and that do not reflect genuine thyroid health.
Many doctors still use a hypothyroidism TSH range of 0.5 to 5.0 even though the American Association of Clinical Endocrinologists recommends 0.3 to 3.0.
In functional medicine, we use an even narrower range of .25 to 1.25. We also know that only looking at TSH can miss hypothyroidism.
For example, TSH may be normal but other thyroid markers are off. That’s why it’s important to order a thyroid panel that includes total and free T4 and T3, reverse T3, free thyroxine index (FTI), T3 uptake, and thyroid binding globulins. Many conditions can cause poor thyroid function, including inflammation, hormonal imbalances, and chronic stress. Ordering these other thyroid markers provides more insight into such imbalances.
Always include a test for autoimmune Hashimoto’s hypothyroidism
In addition to these markers, anyone with symptoms of hypothyroidism should also test for Hashimoto’s, an autoimmune disease that attacks and destroys the thyroid gland.
Why? About 90 percent of hypothyroidism cases in the US are caused by Hashimoto’s. To screen for Hashimoto’s, order TPO and TGB antibodies.
Thyroid medications may be necessary to support thyroid function, but they do not address the autoimmunity attacking the thyroid gland. Failing to manage Hashimoto’s increases the risk of developing other autoimmune diseases such as pernicious anemia, rheumatoid arthritis, vitiligo, and Type I diabetes. It will also make it more difficult to manage your symptoms.

You’re supposed to ditch regular soda for diet soda because it’s better for you, right? Wrong — research shows people who drink diet soda daily are three times more likely to develop dementia or have a stroke compared to those who drink it less frequently.
A 2017 study that tracked almost 3,000 people ages 45 and over for 10 years found those who consumed diet soda daily were almost three times more likely to suffer from ischemic stroke (from blood vessel blockage) or develop Alzheimer’s disease.
Diet sodas are basically a fizzy soup of toxic chemicals, including saccharin, acesulfame-K, aspartame, and artificial colorings.
And while the study did not find the same stroke and dementia risk with sugary sodas, plenty of evidence shows sugar sodas come with their own significant health risks, including obesity, diabetes, heart disease, COPD, and other inflammation-related disorders.
This means you shouldn’t switch from diet soda to sugar soda. Instead, drink neither.
Additionally, if you drink diet soda because you’re watching your weight, you may be surprised to learn diet sodas have been shown to make people fat and prediabetic.
This is because diet sodas skew the composition of gut bacteria in a way that promotes obesity and diabetes. Mouse studies show mice given artificial sweeteners regularly developed high blood sugar compared to control mice and even compared to mice given a diet of high fat and sugar water.
A small follow-up study on human volunteers showed similar results — people who consumed artificial sweeteners developed higher blood sugar and obesity-promoting gut bacteria in just one week.
Artificial sweeteners have also been shown to be toxic to the brain. For instance, the majority of complaints to the FDA about aspartame have been neurological in nature. People report such symptoms as headaches, mood alterations, hallucinations, seizures, nausea, insomnia, anxiety attacks, vertigo, fatigue, rashes, irritability, heart palpitations, slurred speech, loss of hearing, loss of taste, and gut problems.
Aspartame is a known excitotoxin, meaning it causes brain cells to dysfunction, degenerate, and die.
Aspartame also creates toxic byproducts that are linked to lymphomas and leukemias. In one study, rats given the equivalent of four to five bottles of diet soda a day had high rates of these cancers.
If you can’t drink diet soda or sugary soda because you care about your health, what can you drink?
Thankfully, sparkling water has become increasingly popular and available. If you’re not willing to give up a cold fizzy drink, simply opt for sparkling water both at the store and when eating out.
Ditch soda and shore up your healthy gut bacteria
It appears the effect of diet soda on gut bacteria may be an important factor that makes it a health risk.
One of the most importants things you can do for your health is to improve the composition of your gut bacteria.
One of the best ways to do this is to make vegetables the primary part of your diet, including cultured vegetables. Not only are they high in fiber, vitamins, and minerals, but they also feed the good bacteria in your gut and help them grow and thrive.
Additionally, avoid processed foods, sugars, and artificial sweeteners, all of which promote bad bacteria and promote health problems.
