The thyroid gland, located inside the neck, produces two important hormones that travel through the body to regulate metabolism. The Hormone Foundation explains that the thyroid hormones control every organ system in the body, and, when the thyroid gland stops functioning properly, specific symptoms signal a problem in normal functioning. Thyroid conditions, such as hyperthyroidism, hypothyroidism and nodules, may require medical intervention for treatment to regain normal functioning of the thyroid.
Hyperthyroidism Symptoms
Hyperthyroidism occurs when the thyroid gland makes more hormones than the body needs. The National Endocrine and Metabolic Diseases Information Service (NEMDIS) states that approximately 1 percent of the population in the United States have this condition. Symptoms of hyperthyroidism include: fatigue, muscle weakness and heat intolerance. Nervousness, weight loss and mood swings also accompany this disorder. An enlarged thyroid or goiter may appear in the neck area when this disorder is untreated. Additional symptoms include: sleep disturbance, tremors and frequent diarrhea.
Hypothyroidism Symptoms
Hypothyroidism refers to the gland producing too little hormones, ultimately causing a slowed metabolism. The Mayo Clinic recognizes women older than 50 as more likely to have this condition, and, when untreated, a number of additional health problems can develop. Symptoms of hypothyroidism may be less noticeable, such as feeling fatigued and sluggish; however, as the metabolism slows down, additional symptoms appear. Increased sensitivity to cold temperatures and facial puffiness commonly occur with the progression of this disorder. Unexplained weight gain, muscle weakness and depression also may present with the onset of this disorder. This condition becomes life-threatening when untreated after more serious symptoms appear.
Thyroid Nodules
Thyroid nodules cause a swelling in the thyroid gland. The Hormone Foundation states that nodules are common, with half of the population experiencing tiny versions of nodules at some point in life. When the nodules form a lump around the gland location, medical attention is required. The nodules have the potential to be cancerous; although, this is a rare possibility. Nodules may cause a high production of thyroid hormones and lead to symptoms of difficulty breathing and swallowing, as well as fatigue and muscle aches.
