Thyroid disease: Symptoms to look for | Ohio State Medical Center
Do you feel tired all the time, even after sleeping all night? Maybe your hair’s thinning, your skin feels dry, or your mood just isn’t the same. These small issues might seem normal, but they could be signs your thyroid isn’t working properly.
The thyroid is a small gland in your neck that controls your energy, mood, weight, and more. When it’s not working right, your whole body feels it—but the signs are often easy to miss.
Let’s look at 7 common symptoms that might be slowly draining your energy and well-being without you realizing it.
1. You’re Always Tired—No Matter What
If you’re sleeping enough but still feel like you can’t get through the day without coffee or naps, it could be your thyroid.
When your thyroid is underactive (hypothyroidism), your body slows down, making you feel tired all the time.
Fact: About 20 million Americans have thyroid problems—most of them don’t even know it!
2. You Can’t Focus or Think Clearly
That “foggy” feeling in your brain, where you can’t remember things or concentrate, could be more than stress. It’s called brain fog, and it’s very common with thyroid issues.
What it feels like:
- Forgetting names or tasks
- Trouble focusing
- Feeling mentally “off”
3. You’re Gaining Weight Without Eating More
If you’re gaining weight but your habits haven’t changed, your thyroid might be slowing down your metabolism. This means your body isn’t burning energy as fast as it should.
According to the Mayo Clinic, many people with thyroid problems gain 5 to 10 pounds, mostly from water retention.
Signs to watch:
- Sudden weight gain
- Puffy face or hands
- Clothes feeling tighter
4. You’re Always Cold
Are you bundled up while everyone else is fine in a T-shirt? A slow thyroid makes it hard to keep your body warm.
You might notice:
- Cold hands and feet
- Needing a blanket even indoors
- Feeling chilly most of the time
This happens because your body isn’t making enough heat when your metabolism slows down.
5. Your Skin and Hair Are Changing
Is your skin dry, no matter how much lotion you use? Are you seeing more hair in your brush or shower? These are sneaky signs your thyroid may be out of balance.
Common changes:
- Dry or flaky skin
- Hair thinning or falling out
- Eyebrows are thinning, especially on the sides
6. You Feel Sad, Anxious, or Moody
Thyroid hormones affect your mood, too. If you’ve been feeling down, anxious, or snappy without a clear reason, your thyroid could be playing a role.
How it shows up:
- Feeling depressed or low energy
- Mood swings
- Getting irritated easily
According to the NIH, low thyroid levels can lead to depression and anxiety, especially in women.
7. Period Problems or Fertility Issues
Women with thyroid issues often notice their periods become irregular—too heavy, too light, or sometimes skipping altogether. Thyroid problems can also make it harder to get pregnant.
Watch for:
- Heavy or long periods
- Missed or irregular cycles
- Difficulty conceiving
The American Thyroid Association says women are 8 times more likely to have thyroid issues than men.
What’s Causing All These Symptoms?
Most of these signs happen because of hypothyroidism, which means your thyroid is not making enough hormones. Less often, symptoms can come from hyperthyroidism (an overactive thyroid).
Thyroid problems can be caused by:
- Autoimmune diseases (like Hashimoto’s or Graves’)
- Stress
- Pregnancy
- Certain medications
How Can You Feel Better?
Medical Treatments:
- Hypothyroidism: Doctors usually prescribe a daily pill (like levothyroxine) to bring hormone levels back to normal.
- Hyperthyroidism: This might involve medications, radiation, or sometimes surgery.
Natural Support:
- Eat iodine-rich foods (like seaweed, eggs, and dairy).
- Get enough selenium and zinc (Brazil nuts, pumpkin seeds).
- Reduce stress with yoga, meditation, or deep breathing.
- Sleep at least 7–9 hours a night.
- Move your body daily—even a 20-minute walk helps.
