Thyroid problems are common and can cause a variety of unpleasant symptoms. Here are some signs you should check your levels of thyroid hormones.


The thyroid is an essential hormone-producing gland that everyone has. Occasionally, the thyroid fails to work as intended, causing unwanted symptoms and general discomfort. Below, we explain what the thyroid is, what it does, and five signs you should take an at-home thyroid test to rule out thyroid disease.

What Is the Thyroid?

On the lower side of your neck, there’s a butterfly-shaped endocrine gland. This gland is the thyroid.

What Does It Do?

The thyroid excretes two hormones—thyroxine (T4) and triiodothyronine (T3)—into the bloodstream. These hormones affect how active your body’s cells and tissues are. When your thyroid functions properly, it releases the necessary amount of each hormone into the bloodstream. But in people with thyroid disease, the thyroid fails to produce the correct quantity of hormones.

Signs You Need To Take a Thyroid Test

Sometimes, the thyroid excretes too much or too little of T4 and T3, which can result in dysfunction. Thyroid problems are most common in older women but can happen to anyone, regardless of age or gender. If you’re experiencing the symptoms below, it could signify that you have an overactive thyroid (hyperthyroidism), an underactive thyroid (hypothyroidism), or another thyroid condition. If you spot these issues, you should take an at-home thyroid test to confirm your thyroid hormone levels.

Weight Loss or Gain

Thyroid hormones help regulate metabolism. If the body produces too many hormones, it can speed up metabolism and cause extreme weight loss; if it produces too few hormones, it can hamper metabolism and result in weight gain.

Hyperactivity or Exhaustion

Thyroid disease can affect your mood. In people with hyperthyroidism, it can cause hyperactivity and restlessness, and in people with hypothyroidism, it can cause exhaustion and listlessness.

Heat Intolerance or Constantly Feeling Cold

Thyroid disease also affects blood vessels in a way that alters core body temperature. People with hyperthyroidism often feel hot and sweaty, while people with hypothyroidism may struggle to keep warm.


Irritability is a common symptom of both hyperthyroidism and hypothyroidism.

Puffy or Dry Skin

An excess of thyroid hormones can cause the skin around your eyes to retain moisture and puff up; conversely, a lack of thyroid hormones can dry out the skin.
