Always Tired? It Could Be Your Thyroid!

You wake up feeling like you never slept, you push through the morning in a fog, and by mid-afternoon you’re fighting to stay awake. No matter how much coffee you drink, your energy never seems to catch up.

Fatigue is the number one reason people visit the doctor, yet millions are still told their labs are “normal,” even when their symptoms say otherwise. This oversight is especially common when the real culprit is an underactive thyroid. 

Hypothyroidism is one of the most frequently missed causes of persistent, day-to-day exhaustion, largely because many providers don’t order a complete thyroid panel or interpret results correctly.

In this blog, we will explore why thyroid dysfunction causes chronic exhaustion, who is at risk, how to get a complete diagnosis, and the best treatment options available.

The Silent Epidemic Nobody’s Talking About

“A 2023 NIH report estimates that 30 million Americans have some degree of thyroid dysfunction, yet more than half remain undiagnosed.” 

This isn’t just a statistic. It represents millions of people struggling with exhaustion, weight changes, mood issues, and brain fog simply because their thyroid was never fully tested or their labs were read too narrowly.

Understanding the complex relationship between hormones and mental health is crucial for effective hypothyroidism treatment.

Women are hit hardest! 

“By age 60, 1 in 5 women develop subclinical or overt hypothyroidism. 

Postpartum thyroiditis affects up to 17% of new mothers, yet many are misdiagnosed as “stressed,” “overwhelmed,” or “depressed” and then handed an SSRI instead of a thorough thyroid evaluation and proper treatment, as per a 2023 NCBI survey.”

Why Fatigue Gets Dismissed and Why It Shouldn’t

Fatigue is the classic hallmark of hypothyroidism, but it’s commonly minimized or blamed on age, stress, parenting, or lifestyle. 

Meanwhile, other thyroid-related symptoms—dry skin, weight gain, constipation, low mood, brain fog, hair thinning, or sensitivity to cold—can be vague or overlap with other conditions, leading many doctors to overlook the thyroid entirely. This is why consulting experienced hypothyroidism specialists is often necessary.

Seeking out a dedicated thyroid specialist doctor can make all the difference. But untreated hypothyroidism isn’t harmless. Low thyroid function can contribute to:

• Elevated cholesterol and triglycerides
• Heart disease
• Infertility
• Osteoporosis
• Chronic infections
• Cognitive decline

Thyroid dysfunction is also one of the most common secondary causes of high cholesterol. If your thyroid is underactive, cholesterol may remain stubbornly high no matter how clean your diet is until thyroid function is properly restored.

Who Is at Risk for Low Thyroid Function?

Hypothyroidism can occur at any age, but certain life stages significantly increase risk.

1.Postpartum (After Childbirth): 

Fatigue, depression, anxiety, or “brain fog” in new mothers are often labeled as postpartum depression. Yet thyroid dysfunction is a frequently missed underlying cause. A simple TSH test is not enough to catch it.

2.Menopause: 

Symptoms such as mood changes, weight gain, forgetfulness, and temperature swings mimic menopausal changes—but they’re also classic signs of low thyroid function. 

“Women in menopause should always have thyroid function evaluated, especially since untreated hypothyroidism can raise cholesterol by 30–50% and increase heart disease risk. (Source: NLM)”

3.Age 60 and Above: 

For many older adults, slowing down isn’t “just aging.” A sluggish thyroid is often the real source of tiredness, brain fog, and reduced metabolism, and treatment can dramatically improve energy, mood, and cognitive sharpness.

Do You Have Symptoms of Hypothyroidism?

Common signs include:

• Persistent fatigue or low energy
• Weight gain or difficulty losing weight
• Dry skin or brittle nails
• Hair thinning or excessive shedding
• Cold hands and feet
• Depression, low mood, or brain fog
• Constipation
• Slow heartbeat
• High cholesterol

Anyone with these symptoms should undergo a complete thyroid evaluation! 

Specific strategies, like focusing on thyroid hair loss treatment, can be a primary concern for many patients seeking effective management. Finding the best thyroid supplement for hypothyroidism may also be discussed to support recovery. Some patients may also look for a beneficial food supplement for thyroid health.

While TSH is a widely used test, it is not enough on its own. A deeper understanding comes from ordering:

• Free T3
• Free T4
• Reverse T3 (inactive thyroid hormone)
• Thyroid antibodies: TPO and Thyroglobulin antibodies (to rule out Hashimoto’s)

Hashimoto’s thyroiditis, the autoimmune form of hypothyroidism, is rapidly increasing and often goes undetected without antibody testing.

Try This Simple At-Home Thyroid Screening

Basal body temperature testing can give you a rough sense of your metabolic activity. It is not diagnostic, but it can help determine whether you should request a full thyroid panel.

How to Perform the Test?

• Before bed, shake down a thermometer to below 95°F
• Keep it within reach.
• Upon waking (without getting out of bed), place the thermometer under your arm:
• 10 minutes for a glass thermometer
• 2 minutes for a digital thermometer
• Record temperature, date, and time.
• Repeat for 3 consecutive days.
• Menstruating women: test on cycle days 2–4.
• Men and postmenopausal women: test any time.

Interpreting Results

• Normal: 97.6°F – 98.2°F
• Consistently below 97.8°F: may indicate lower metabolic activity and possible thyroid dysfunction, especially when symptoms are also present.

If your temperatures are low and you’re experiencing signs of hypothyroidism, request a full thyroid evaluation. Proper diagnosis and treatment can make a dramatic difference.

What About Thyroid Treatment? 

Thyroid Treatment Works, but Choosing the Right Therapy Matters!

Most people respond very well to thyroid hormone replacement. But not all thyroid medications are the same. The focus of effective hypothyroidism treatment is finding the optimal balance for the individual and addressing secondary issues like thyroid hair loss treatment.

The most widely prescribed medication, Synthroid (levothyroxine), contains only T4, a hormone that must be converted into the active T3 form inside the body. But many people struggle with this conversion, leaving them symptomatic despite “normal” labs. 

That’s why many integrative and functional physicians prefer natural desiccated thyroid (NDT), such as Armour Thyroid or NP Thyroid, which is considered a more natural hypothyroid treatment approach than T4-only therapy. 

Often these providers function as holistic thyroid doctors, focusing on root causes. NDT contains a balanced combination of: 

• T4 
• T3 
• Or a compounded combination of the two.  

Some clinical studies suggest that patients taking both T3 and T4 often experience better energy, mood, mental clarity, and overall well-being compared with T4 alone. 

If you’ve been on T4-only therapy and still feel tired, foggy, or sluggish, speak with your doctor about whether a more complete thyroid hormone approach may serve you better.

The Bottom Line

If you’re always tired, don’t brush it off, and don’t let anyone else brush it off either. Fatigue is not “just part of life.” It’s your body asking for help. Identifying and treating thyroid dysfunction can restore your energy, mood, metabolism, and overall well-being.
