As we get older, our bodies slow down in some ways. One small but important part of the body is the thyroid. Even though it is small, it plays a big role in how we feel every day.

Many seniors have thyroid problems and don’t even know it. The symptoms often feel like “normal aging,” but treatment can make a big difference.

What Is the Thyroid?

The thyroid is a small, butterfly-shaped gland in the front of your neck. It helps control:

  • Energy levels

  • Weight

  • Heart rate

  • Body temperature

  • Mood and memory

When the thyroid is not working properly, it can affect your whole body.

Common Thyroid Problems in Older Adults

Underactive Thyroid (Most Common)

This happens when the thyroid does not make enough hormone.

Common signs include:

  • Feeling tired all the time

  • Gaining weight easily

  • Feeling cold when others are not

  • Constipation

  • Dry skin or hair thinning

  • Feeling down or forgetful

Many people think these are just signs of aging, but they may be caused by thyroid problems.

Overactive Thyroid

This happens when the thyroid makes too much hormone.

Signs may include:

  • Losing weight without trying

  • Fast or irregular heartbeat

  • Feeling nervous or shaky

  • Trouble sleeping

  • Weak muscles

In seniors, an overactive thyroid can increase the risk of heart problems and bone loss.

Why Thyroid Problems Are Often Missed

Thyroid symptoms can look like normal aging. Because of this, many seniors never get tested. A simple blood test can check thyroid levels and help doctors decide if treatment is needed.

Thyroid Health and Bone Strength

Thyroid problems can affect your bones. Too much thyroid hormone can weaken bones and raise the risk of fractures. Keeping thyroid levels balanced helps protect bone health as you age.

Eating for Thyroid Health

A healthy diet supports the thyroid and overall well-being.

Helpful nutrients include:

  • Iodine (found in iodized salt and seafood)

  • Selenium (found in eggs, fish, and nuts)

  • Zinc (found in meat, beans, and seeds)

Always talk to your doctor before taking supplements.

Medications and the Thyroid

Some medicines can affect the thyroid. Always tell your doctor about:

  • All prescription medicines

  • Over-the-counter drugs

  • Vitamins and supplements

If you take thyroid medication, take it exactly as directed.

When to Talk to Your Doctor

Talk to your doctor if you notice:

  • Ongoing tiredness

  • Sudden weight changes

  • Memory or mood changes

  • Heart pounding or racing

  • Feeling too hot or too cold

Regular checkups can help catch thyroid problems early.

Living Well With Thyroid Conditions

Most thyroid problems can be treated. With the right care, seniors can feel better, stay active, and enjoy a good quality of life.

Final Thought

Feeling tired, cold, or forgetful is not always “just getting older.” Your thyroid may be involved. Paying attention to symptoms and getting tested can help you stay healthier and feel your best as you age.
