Grave's disease is an autoimmune disorder that causes your body to produce excess amounts of thyroid hormone resulting in an overactive thyroid, or hyperthyroidism. While other medical conditions can cause hyperthyroidism, Grave's disease is one of the most common causes. Also, many Grave's disease symptoms can mimic those of other diseases, and because of this, a prompt and accurate diagnosis is essential. Here are some ways your primary care physician can confirm the diagnosis of Grave's disease. 

Physical Signs

During your physical examination, your primary care physician will examine your neck and eyes. Grave's disease can cause your thyroid gland to swell which can produce a lump in your neck. This lump is called a goiter and can develop in the presence of both hypothyroidism and hyperthyroidism. When a goiter develops as a result of hypothyroidism, or low thyroid function, it is usually the result of an autoimmune condition known as Hashimoto's disease.

To differentiate from these two conditions, your primary care doctor will examine your eyes. Grave's disease often causes bulging of the eyes known as Graves' ophthalmopathy. Conversely, low thyroid function and Hashimoto's disease do not cause this eye condition. Other signs of Grave's disease your physician will look for are fine hand tremors which are the result of an overproduction of thyroid hormones. Thickened red skin on the tops of your feet or legs may also indicate the presence of Grave's disease. This sign is known as Graves' disease dermopathy.

Medical History and Blood Tests

In addition to your physical examination, your healthcare provider will inquire about your symptoms. If you inform your doctor that you are experiencing symptoms such as anxiety, weight loss, diarrhea, profuse sweating, and a rapid heartbeat, they may suspect Grave's disease – especially if your symptoms are accompanied by a goiter or Grave's ophthalmopathy. You may also experience eye pressure and a gritty sensation in your eyes, accompanied by redness, light sensitivity, and frequent tearing.

Finally, your doctor may order blood tests such as a TSH test to confirm your diagnosis. This test helps your primary care physician determine if you have thyroid disease. People who have Grave's typically have decreased levels of circulating TSH, where those with Hashimoto's disease generally have increased levels of TSH.

If you experience any of the above signs and symptoms of Grave's disease, make an appointment with your primary care doctor. Grave's disease is common and very treatable with medications and certain dietary changes such as limiting your intake of caffeine.
