Hypothyroid Symptom Quiz
This hypothyroid symptom quiz gives you a weighted score built around the symptoms most specifically associated with low thyroid function. It accounts for risk factors such as age, sex, family history, and more, in order to give you the most accurate risk assessment.
Here’s how to use it:
Check every symptom that has been present for you for the last 2 months, flag any risk modifiers (these improve your accuracy), and hit calculate.
Your total is given out of a possible 57 points and places you into four tiers with steps on what to do next. It’s that easy.
The scoring system is built on the specificity principles used in validated clinical instruments, including the Zulewski clinical score and the Colorado Thyroid Disease Prevalence Study checklist[1][2].
Note: This quiz is a screening tool, not a diagnosis. A diagnosis of hypothyroidism requires lab confirmation with TSH and Free T4 at a minimum. Never start, stop, or change thyroid treatment based on this score alone.

How to Use This Quiz
Step #1: Check the Symptoms That Apply to You
Because your thyroid impacts every system in your body, that’s how I organized the quiz. You’ll see symptoms listed as metabolic, digestive, mental and cognitive, skin and hair and nails, cardiovascular, reproductive, muscle and nerve, and voice and neck.
Go through each section and check any symptoms that have been present for you for at least 2 months.
Don’t over-check! A symptom that comes and goes occasionally, or that’s clearly related to something else (a new medication, a stressful month, a recent illness, a bad night’s rest), doesn’t belong.
And if you’re unsure, skip it.
Step #2: Add Your Risk Modifiers
The Risk Modifiers section at the bottom of the quiz refines the accuracy of your results by asking you questions that strongly influence hypothyroid risk.
These include: being female and over 35, postpartum within the past 12 months, a family history of thyroid disease, a personal history of another autoimmune condition, and a history of head or neck radiation or radioactive iodine treatment.
These matter because hypothyroidism is 5 to 8 times more common in women, increases sharply after 35, spikes in the 12 months after childbirth (postpartum thyroiditis affects 5 to 10 percent of women[3]), and clusters in families and in people with other autoimmune conditions.
Ignoring these factors would underestimate real-world risk in anyone who has them.
Even one modifier changes your total risk in a meaningful way, so check every one that applies.
Step #3: Read Your Score and Follow the Next Step
Click “Calculate My Score”, and your total appears out of a possible 57 points (46 symptom points plus 11 modifier points).
Your total places you into one of four tiers: Low Likelihood (0 to 9), Mild Pattern (10 to 19), Moderate Pattern (20 to 29), or Strong Pattern (30 and above).
Each tier comes with a specific next step:
- A Low score means your symptoms are most likely caused by something other than your thyroid.
- A Mild or Moderate score means your thyroid is worth investigating, starting with a baseline or full thyroid lab panel.
- A Strong score (the top 10 to 15 percent of completers) means your symptom pattern is uncommonly consistent with hypothyroidism and strongly warrants a complete lab workup.
If your score is Moderate or higher, request a full thyroid panel (TSH, Free T3, Free T4, reverse T3, TPO antibodies, and thyroglobulin antibodies) and then plug the results into the Optimal Thyroid Lab Test Calculator to see where your numbers fall against optimal ranges, not just reference ranges which is what your doctor will try to use.
Understanding Your Results
Your Score
Your score is the total of the weighted symptoms and risk modifiers you checked.
The maximum possible total is 57: 46 symptom points from 25 weighted symptoms, plus 11 modifier points from 5 risk factors.
Every symptom has a weight of 1, 2, or 3 depending on how specifically it points to hypothyroidism.
Highly specific symptoms (thinning of the outer eyebrows, body temperature below 97.8°F, the sensation of physical slowing, and visible neck swelling) count 3 points each.
Moderately specific symptoms (puffiness, cold hands and feet, heavy periods, hair loss, dry skin, slow resting pulse) count 2 points.
Nonspecific symptoms (generic fatigue, bloating, low mood, low libido) count 1 point.
This weighting is why a lower number of highly specific symptoms can produce a higher score than a longer list of vague ones. I designed it this way to account for overlap in symptoms from other conditions.
Your Symptom Pattern Breakdown
Below your score, the quiz shows the three body systems where your strongest symptom pattern falls.
This is helpful for you because certain combinations are more suggestive of hypothyroidism than others.
A strong pattern in the metabolic and skin/hair sections is much more predictive than a scattering of unrelated symptoms across other systems.
If your modifiers add substantial points, those are summarized separately so you can see how much of your total risk comes from your pretest probability versus your symptoms.
Your Risk Tier
The four tiers are calibrated conservatively:
- A Low score (0 to 9) means your symptoms are few or nonspecific, and thyroid disease is less likely than another cause.
- A Mild score (10 to 19) means some overlap with hypothyroidism but also overlap with stress, iron deficiency, perimenopause, sleep problems, and depression.
- A Moderate score (20 to 29) means your pattern is clearly consistent with hypothyroidism and warrants a full thyroid panel.
- A Strong score (30 or higher) means your symptom cluster is uncommonly consistent with hypothyroidism, and a complete workup is strongly recommended.
Only the top 10 to 15 percent of completers reach the strong tier, which is by design and meant to reflect what we would actually see in the real world.
Your Recommended Next Step
The next-step recommendation scales with your tier.
A Low tier suggests monitoring and addressing more likely drivers first: iron, vitamin D, B12, sleep quality, and stress.
A Mild tier suggests baseline labs (TSH and Free T4 at minimum).
A Moderate or Strong tier recommends a complete thyroid panel: TSH, Free T3, Free T4, reverse T3, TPO antibodies, and thyroglobulin antibodies.
Regardless of tier, once you have thyroid labs in hand, the Optimal Thyroid Lab Test Calculator will tell you whether your numbers fall within the optimal range used in functional and integrative medicine, not just the standard reference range.
A number that sits inside the reference range but near the edges is frequently symptomatic, and that’s often where the answer lives.
Most Common vs. Most Specific Hypothyroid Symptoms
Not all hypothyroid symptoms carry the same diagnostic weight. Some are extremely common in hypothyroid patients across the board (fatigue, weight gain, and dry skin) but are non-specific.
Others are much less common but far more specific[1][2].
This quiz automatically weights these differently. Here’s a quick reference of how it plays out mathematically:
| Most Common Hypothyroid Symptoms (reported by most hypothyroid patients) | Most Specific Hypothyroid Symptoms (strongest predictors of low thyroid function) |
|---|---|
| Fatigue not improved by sleep | Thinning of the outer third of the eyebrows |
| Unexplained weight gain | Morning body temperature below 97.8°F |
| Cold intolerance | Non-pitting puffiness of face and hands |
| Dry, rough, or coarse skin | Resting heart rate below 60 beats per minute |
| Constipation | Physical slowing (“moving through molasses”) |
| Hair loss or thinning from the scalp | Visible swelling in the front of the neck |
| Brain fog and short-term memory problems | Hoarse voice or throat tightness |
| Depression or flat mood | Cold hands and feet in warm environments |
| Muscle aches and stiffness | Delayed deep tendon reflexes |
| Heavy, long, or irregular menstrual periods | Unexplained rise in cholesterol |
The most specific symptoms (the right column) are the ones clinicians relied on when physical examination was the primary diagnostic tool, before TSH testing became routine.
They remain the most reliable physical pointers toward hypothyroidism today, which is why this quiz weighs them more heavily than generic symptoms.
A patient reporting three or four of the highly specific symptoms has a much higher probability of underlying thyroid disease than a patient reporting a dozen nonspecific ones.
Frequently Asked Questions
The first signs of hypothyroidism are usually fatigue that isn’t relieved by sleep, unexplained weight gain, cold intolerance, constipation, dry skin, and hair that’s shedding or thinning more than usual[1][4]. These early symptoms appear gradually over months to years, which is why they’re commonly blamed on stress, aging, or perimenopause before thyroid disease is suspected.
More specific early signs that are often dismissed because they seem unrelated include puffiness of the face or hands in the morning, thinning of the outer third of the eyebrows, a slow resting pulse (under 60 bpm), a morning body temperature below 97.8°F, and a physical sense of slowing. When symptoms from multiple body systems appear together, the probability of hypothyroidism rises sharply, and a full thyroid panel becomes worth requesting.
The most specific symptoms of hypothyroidism (the ones least likely to be explained by other causes) are thinning of the outer third of the eyebrows, a morning body temperature consistently below 97.8°F, non-pitting puffiness of the face and hands, a resting heart rate under 60 beats per minute, and a physical sense of slowing often described as “moving through molasses.” These are the signs clinicians relied on for decades before TSH testing, and they remain the strongest physical pointers toward hypothyroidism today[2].
These symptoms matter more than generic complaints like fatigue or weight gain because they point specifically at low thyroid hormone activity rather than the many other conditions that cause those vague symptoms. That’s why this quiz weights them more heavily. A patient reporting three or four highly specific symptoms has a much higher probability of underlying thyroid disease than a patient reporting a dozen nonspecific ones.
Yes, you can have symptoms of low thyroid function with a technically “normal” TSH. The standard TSH reference range (roughly 0.45 to 4.5 mU/L at most U.S. labs) captures about 95 percent of the population, but the upper end of that range overlaps heavily with people who have early or subclinical thyroid dysfunction. A TSH between 2.5 and 4.5 mU/L reads as “normal” on a lab report but is symptomatic for many patients[5].
The optimal TSH for most hypothyroid patients is closer to 1.0 to 2.0 mU/L, not the upper end of the reference range. If your symptoms are consistent with hypothyroidism but your TSH is in the upper half of normal, a full panel is worth requesting. TSH alone misses subclinical hypothyroidism, autoimmune thyroid disease (Hashimoto’s), and T4-to-T3 conversion problems. For more on this, read my guide on optimal TSH levels for thyroid patients.
Thinning of the outer third of the eyebrows (sometimes called the Queen Anne’s sign or the sign of Hertoghe) is a classic physical sign of hypothyroidism. Low thyroid hormone slows hair follicle turnover, and the outer eyebrows are one of the first places it shows up because those follicles naturally cycle more slowly to begin with.
Eyebrow thinning isn’t exclusive to thyroid disease. Aging, alopecia areata, iron deficiency, zinc deficiency, biotin deficiency, chronic over-plucking, and some autoimmune conditions can also cause it. But when eyebrow thinning appears alongside fatigue, cold intolerance, dry skin, or weight gain, hypothyroidism climbs to the top of the likely causes. It’s one of the most specific hypothyroid signs, which is why this quiz weights it as a 3-point symptom instead of a 1-point one.
No, weight gain is not always a sign of hypothyroidism, but unexplained weight gain (especially weight that continues to climb despite reasonable diet and activity) is one of the more common hypothyroid symptoms. Untreated hypothyroidism typically causes 5 to 15 pounds of gain driven by slowed metabolism, fluid retention, and constipation[1]. Gain much beyond 20 pounds is rarely caused by thyroid alone.
Other common drivers of weight gain include insulin resistance, cortisol dysregulation, perimenopause, certain medications (antidepressants, beta-blockers, corticosteroids), and age-related loss of muscle mass. If thyroid is confirmed and corrected but weight still won’t move, the Hypothyroid Calorie Calculator accounts for the metabolic suppression hypothyroidism causes even when treated. For more on weight that persists on medication, read my post on levothyroxine and weight gain.
Yes, hypothyroidism can cause brain fog, memory problems, depression, and in some patients anxiety. Thyroid hormone regulates neurotransmitter production, cerebral blood flow, and neuronal energy metabolism, so low thyroid levels directly affect both cognition and mood[6].
Depression and flat mood are more commonly tied to hypothyroidism than anxiety, but both appear clinically. A subset of patients with subclinical or early hypothyroidism report anxiety as their primary symptom, often because under-replacement drives a compensatory adrenaline response. Brain fog and short-term memory problems usually improve within 6 to 12 weeks of proper thyroid replacement, though residual cognitive symptoms are common in long-standing untreated cases.
Hypothyroid fatigue feels different from normal tiredness. Patients consistently describe it as a heavy, weighted-down exhaustion that doesn’t improve with a full night of sleep, where ordinary physical activity feels disproportionately hard and recovery takes much longer than it used to. It’s often paired with a sense of physical slowing, as if the body is moving through molasses.
This pattern distinguishes it from the fatigue of iron deficiency (which typically improves with rest), depression (which comes with loss of interest and motivation), sleep apnea (which improves with sleep treatment), and adrenal-type fatigue (which cycles through the day). Hypothyroid fatigue is remarkably consistent: present in the morning regardless of sleep, worse with physical effort, and paired with cold intolerance, dry skin, and cognitive slowing. That cluster is part of why this quiz weights combinations of specific symptoms more heavily than fatigue in isolation.
Feeling cold all the time, especially in the hands and feet, is one of the most specific symptoms of hypothyroidism. Thyroid hormone drives basal metabolic rate and heat production, so low thyroid levels lead to lower core body temperature, cold extremities, and difficulty tolerating air-conditioned or cool environments that everyone else finds comfortable.
The pattern of hypothyroid cold intolerance is distinctive: it’s consistent day to day rather than just worse in winter, it affects the hands and feet specifically, and it’s usually paired with a morning body temperature under 97.8°F. Other causes of chronic cold sensitivity include iron deficiency anemia, chronic underfeeding or anorexia, Raynaud’s phenomenon, low blood pressure, and peripheral vascular disease. When cold intolerance occurs alongside fatigue, weight gain, and dry skin, hypothyroidism becomes the most likely single explanation.
Hypothyroidism and perimenopause share a remarkable number of symptoms (fatigue, weight gain, hair thinning, brain fog, mood changes, low libido, disrupted sleep, and menstrual irregularities), which is why they’re commonly confused and often coexist. The two can’t be separated on symptoms alone. Lab testing is required.
A few symptoms lean more strongly one way. Hypothyroidism specifically causes cold intolerance, constipation, eyebrow thinning, dry coarse skin, and a slow resting heart rate. Perimenopause causes hot flashes, night sweats, cycle shortening followed by cycle lengthening, and vaginal dryness. Fatigue, weight gain, and mood changes appear in both. Many women over 40 have both conditions at the same time, which is why a full thyroid panel belongs in any perimenopause workup rather than assuming the symptoms are purely hormonal.
Hashimoto’s thyroiditis is the autoimmune disease that causes most cases of hypothyroidism in countries with adequate iodine intake. Said simply: Hashimoto’s is the underlying disease, and hypothyroidism is the functional result. A patient with Hashimoto’s eventually develops hypothyroidism as the immune system slowly destroys thyroid tissue, though antibodies can be elevated for years before thyroid function actually drops[7].
The practical difference is diagnostic and management-related. Diagnosing Hashimoto’s requires antibody testing (TPO antibodies and thyroglobulin antibodies), while diagnosing hypothyroidism requires only TSH and Free T4. Treatment overlaps (both are managed with thyroid hormone replacement), but a Hashimoto’s diagnosis opens up additional strategies around autoimmune management, including gluten avoidance, selenium supplementation, and identifying other autoimmune triggers.
