Symptoms and Signs of Thyroid Nodules

Doctor's Notes on Thyroid Nodules
(Thyroid Nodule)

The thyroid gland in the neck produces thyroid hormone, which is needed for normal growth and metabolism. Lumps called nodules may appear on the thyroid and may be either solid or fluid-filled. Thyroid nodules are more common as people age, and most are benign and not cancerous. A physician may detect a nodule during a physical exam, or they may be found during imaging such as on computed tomography (CT scan), magnetic resonance imaging (MRI), or ultrasound of the front of the neck.

Most of the time, thyroid nodules do not cause symptoms. When they do occur, symptoms of thyroid nodules may include a visible lump on the front of the neck, a rapidly growing lump on the front of the neck, a lump felt in the throat, difficulty swallowing, hoarseness, other enlarged glands or lymph nodes in the neck, and in rare cases, pain.

It's hard to tell if you have thyroid abnormalities. You might feel run down and tired, or have what is known as "brain fog." You may be gaining weight, pregnant, or experiencing hair loss. Others may feel "hyper," anxious, or sweat a lot more than usual. All of these are common symptoms of thyroid disorders. The thyroid gland regulates many processes within the body, and women are particularly likely to have disorders that affect the function of this essential gland. Recognizing and treating these conditions is critical for optimum health and preventing long-term health problems.
