If you’re feeling off and can’t quite put your finger on what’s going on, you might want to check in with your thyroid gland. The thyroid is tiny but mighty, responsible for regulating metabolism, growth, and development.

When it’s not functioning properly, it can wreak havoc on your body. Here are some signs to keep an eye out for:.

Unexplained Weight Gain or Loss

If you’ve been eating healthily and exercising regularly but still seem to be putting on weight, your thyroid could be to blame. Conversely, if you’re losing weight despite not trying to, this could also be a sign of a thyroid problem.

In either case, it’s worth getting checked out.

Fatigue

Feeling tired all the time could be due to many different factors, but if you’ve ruled out other causes and have a sluggish metabolism, your thyroid could be the culprit. Hypothyroidism, or an underactive thyroid, can cause fatigue and brain fog.

Mood Swings

Thyroid hormones play a big role in regulating mood. If you’re experiencing depression, anxiety, or irritability, your thyroid might be involved, especially if you don’t have a history of mental health issues.

Hair Loss

If you’re noticing more hair in your brush or shower drain than usual, it could be due to an overactive thyroid. Hyperthyroidism can cause hair to become thin and brittle.

Changes in Heart Rate

The thyroid gland helps regulate heart rate and rhythm. If you’re noticing heart palpitations or a faster-than-normal heartbeat, your thyroid could be to blame.

Muscle Weakness

Feeling weak or fatigued in your muscles, especially in your arms and legs, could be due to an underactive thyroid. Hypothyroidism can cause muscle pain and cramps as well as weakness.

Changes in Digestion

Thyroid hormones help regulate digestion, and an imbalance can cause constipation, diarrhea, or other digestive issues.

Changes in Menstrual Cycle

Thyroid hormones also play a role in regulating menstrual cycles. If you’re experiencing irregular periods, heavy bleeding, or other changes, an overactive or underactive thyroid could be involved.

Intolerance to Heat or Cold

An overactive thyroid can make you feel like you’re always overheating, while an underactive thyroid can make you feel constantly chilly.

Skin Changes

Thyroid hormones help regulate skin health, so changes in your skin could be due to a thyroid issue. Dry, itchy skin is a common symptom of hypothyroidism, while an overactive thyroid can cause your skin to become flushed and sweaty.

If you’re experiencing any of the above symptoms, it’s worth getting your thyroid checked out.

A simple blood test can determine whether your thyroid hormone levels are normal, and your doctor can help you determine the best course of action if there is an imbalance.
