Aging brings changes that can sometimes hint at more than just growing older. For many, a silent condition could be quietly affecting daily life without warning.

Could you be overlooking the hidden signs of a common yet misunderstood health issue?


Hypothyroidism occurs when your thyroid gland, that butterfly-shaped organ nestled in your neck, doesn't produce enough thyroid hormone.

This hormone is a bit of a VIP in the body—it regulates metabolism, which in turn affects everything from your heartbeat to how quickly you burn calories.


According to Dr. Shuchie Jaggi, DO, an endocrinology specialist and co-director of the thyroid program at Lenox Hill Hospital, hypothyroidism can have a domino effect on multiple organs, including the heart and brain.

It's a condition that doesn't discriminate, affecting roughly 5% of Americans over the age of 12, with a higher prevalence in women and the elderly.

Dr. Erik Alexander, MD, chief of the thyroid section at Brigham and Women's Hospital and professor of medicine at Harvard Medical School, points out that hypothyroidism's symptoms can be so subtle and gradual that they're often mistaken for normal aging.

But there's nothing normal about the fatigue that feels like you're dragging an anchor, or the constipation that's more stubborn than a mule. Other telltale signs include:

• Dry, itchy skin that no lotion can tame
• A sensitivity to cold that has you wearing sweaters in July
• Menstrual irregularities that throw you for a loop
• Brain fog that makes concentration a Herculean task
• Muscle aches that make you feel like you've run a marathon in your sleep

These symptoms can be elusive and easily attributed to other conditions, which is why hypothyroidism is often confirmed through blood tests rather than a symptom checklist.

The most common instigator of hypothyroidism is Hashimoto's disease, an autoimmune disorder where the body mistakenly attacks the thyroid. But that's not the only possible cause.

Hypothyroidism can also arise from:

• Congenital factors, meaning you were born with it
• Surgical removal or partial removal of the thyroid
• Radiation treatment targeting the thyroid
• Certain medications that interfere with thyroid function
• Disorders affecting the pituitary gland or hypothalamus
• Iodine deficiency, which is rare in the United States due to iodized salt
• Other autoimmune diseases that like to keep company

If you suspect your thyroid is on a go-slow, it's crucial to see a physician.

Dr. Alexander emphasizes that any level of hypothyroidism warrants a medical evaluation to understand what you're dealing with and how to move forward.

While some mild cases may resolve on their own, chronic conditions like Hashimoto's require long-term management.

The standard treatment is a synthetic thyroid hormone called levothyroxine, which essentially replaces what your body is lacking.

Regular blood tests will help your healthcare provider fine-tune your dosage to get your thyroid levels back on track.

Letting hypothyroidism go untreated isn't just about tolerating discomfort—it can be downright dangerous.

Severe hypothyroidism can lead to myxedema, a life-threatening state that can plunge patients into a coma, warns Dr. Jaggi.

If you're experiencing any of the symptoms mentioned, or if something just feels off, don't chalk it up to “just getting older.”

Early detection and treatment of hypothyroidism can make a world of difference in your quality of life.
