The most common early warning signs of a thyroid problem include unexplained tiredness, constipation, dry skin, body temperature problems, weight gain, hoarseness, and mood imbalances. These symptoms may seem unrelated, but when taken together, can amount to thyroid concerns.
That being said, while symptoms of an illness, condition, or disease are usually the motivator to get you to the doctor, they’re not always the best indicator for what may actually be ailing you. Looking out for particular symptoms and getting regular checkups if you have a family history of a particular disease, such as thyroid problems, GI disorders, high blood pressure, or certain cancers, is most certainly a good idea. But in the case of thyroid issues specifically, blood tests are the most accurate way to get a truly reliable picture of what’s going on.
In other words, although it’s important to recognize and understand the symptoms, they’re not very predictive when it comes to diagnosing hypothyroidism — low levels of thyroid hormone production in the butterfly-shaped gland at the front of your neck. (In this article, we’re focused on hypothyroid, or underactive thyroid, rather than hyperthyroid, or overactive thyroid/too much thyroid hormone.)
There are a number of different possible symptoms of hypothyroidism, but having one or two of those symptoms is not a reliable indicator that you have a thyroid problem, largely because many hypothyroidism symptoms overlap with symptoms of other conditions (some of which, like IBS and other digestive disorders, are more common or more likely). In fact, hypothyroidism only affects about 1% of the population, while IBS (irritable bowel syndrome) affects closer to 15% of the population [1, 2].
So what are early warning signs of thyroid problems? Let’s go over what to look out for, the tests that will be most indicative of a problem, and what to do if your levels are normal but you’re still experiencing symptoms of hypothyroid.
What Are Early Warning Signs of Thyroid Problems?
As we already mentioned, many of the symptoms we’re about to enumerate can also be symptoms of other diseases or conditions. So it’s important to understand that displaying one, two, or even three symptoms from this list doesn’t necessarily mean you have a thyroid condition.
Importantly, the more symptoms you have from this list, the greater the likelihood that your issue is in fact with your thyroid, especially if you’re experiencing fouror more of these symptoms [3 Trusted SourcePubMedGo to source]. Early warning signs of a thyroid disorder or reduced thyroid function, in order of prevalence, include:
For example, Hashimoto’s thyroiditis is an autoimmune condition that directly affects the thyroid and can lead to hypothyroidism. It’s the most common cause of hypothyroidism in the United States [7 Trusted SourcePubMedGo to source].
Your healthcare provider should be looking at your whole picture of health, including family history, other related illnesses, and above all, requesting labs so that you can have a very concrete idea of the state of your endocrine system and whether or not you’re making enough hormones.
Blood Tests for Thyroid Health
Because the most common symptoms of hypothyroidism overlap with other health challenges, it’s important to dig a little bit deeper than the symptoms to get to the root cause. Screening for symptoms can be useful in younger populations, but for the elderly, especially for women over 60 — which represent 47.4% of all autoimmune hypothyroid patients — it’s not a useful tool [3 Trusted SourcePubMedGo to source].
Importantly, no individual symptom can help predict whether or not a person is in need of HRT or other thyroid meds. Measuring TSH (thyroid-stimulating hormone), free T4 (thyroxine), and TPO (thyroid peroxidase) antibodies through bloodwork is the best way to verify if your symptoms could be attributable to thyroid dysfunction. From there, you can determine whether or not your levels are low enough to merit taking medication, or if something else might be going on that’s affecting your energy levels, skin, and digestion.
While medical tests like blood work aren’t always the best predictors for every disease, in the case of thyroid hormone levels, blood work is actually the gold standard and very reliable. It’s worth getting labs done if you have any suspicion at all that you might have hypothyroidism. This type of blood work is relatively inexpensive, and knowing your levels is an important jumping-off point for next steps. It’s also a great way to avoid taking unnecessary medication.
Furthermore, all prescription drugs come with potential side effects, and thyroid medications are no different. Taking them when they’re not actually needed increases your risk of experiencing side effects, and for no good reason.
If you’re truly hypothyroid, you will benefit from thyroid medications and should take them. But if you have normal thyroid levels or subclinical hypothyroidism, there’s no reason for a healthcare professional to shoehorn you into a diagnosis and over-treat the problem with meds just because some of the symptoms line up.
It’s important to know your body and to notice if symptoms begin to crop up that don’t have an obvious explanation. Many symptoms point to more than one disease or dysfunction, so while knowing which symptoms to look out for is a good idea, it’s also critical to know when it’s time to ask your doctor for blood work.
What are early warning signs of thyroid problems? The big ones to look out for are unexplained tiredness, constipation, cold intolerance, weight gain, hoarseness, mood imbalances, and muscle weakness. The more of these you have, the more likely it is that you have a thyroid problem. But blood work is the only way to know for certain if you have clinically low levels of thyroid hormone.
If you’ve been told that your thyroid hormone ranges are normal or subclinical but you still have lots of symptoms, you should seek a second opinion before beginning HRT or other thyroid med regimens. It’s not only possible but likely that your symptoms are gut-related and could be addressed with dietary changes and probiotics.
