Graves' disease is one of the causes of hyperthyroidism (overactive thyroid). It's caused by an autoimmune attack on the thyroid gland that leads to the overproduction of thyroid hormones.

Graves’ disease, an autoimmune disorder that leads to overactivity of the thyroid gland, commonly known as hyperthyroidism, presents a unique set of challenges for seniors. The thyroid gland, located in the neck, produces hormones that regulate the body’s metabolic rate, affecting body temperature, heart rate, and even the body’s use of energy. Understanding and recognizing Graves’ disease, its prevalence in senior populations, and the associated signs and symptoms can help you or a loved one receive timely treatment.

The diagnosis of Graves’ disease typically involves the identification of symptoms, a physical examination, blood tests, and occasionally, imaging tests. The primary treatment options encompass anti-thyroid medications, radioactive iodine therapy (RAI), and in rare cases, surgery. These treatments aim to alleviate symptoms and regulate thyroid hormone levels.

In seniors, Graves’ disease can be more challenging to diagnose due to the overlap of its symptoms with those of other common conditions in this age group. Therefore, seniors and their caregivers should be aware of the signs and symptoms of Graves’ disease, which mirror those of hyperthyroidism, such as:

  • Unexpected weight loss
  • Heart palpitations
  • Chronic fatigue
  • Shortness of breath
  • Dizziness
  • Muscle weakness
  • Agitation or irritability
  • Insomnia or other sleep disturbances
  • Excessive sweating or heat intolerance
  • Tremors, especially visible in the hands
  • Altered bowel habits, such as diarrhea or frequent bowel movements
  • Changes in appetite, often increased but sometimes decreased
  • Thinning hair
  • Fertility issues and menstrual-cycle changes in women
  • Hypertension (high blood pressure).

Furthermore, Graves’ disease is frequently associated with a goiter, or an enlarged thyroid gland. However, some symptoms are specific to Graves’ disease and not typically seen in other forms of hyperthyroidism. These include:

  • Graves’ ophthalmopathy or orbitopathy: This condition affects about a third of those with Graves’ disease and can lead to “bulging eyes” due to swelling caused by the autoimmune process behind the disease. Symptoms may include eye discomfort, sensitivity to light, and reduced vision.
  • Skin lesions: Known as Graves’ dermopathy, this symptom involves the thickening and swelling of the skin, accompanied by intense itching. In advanced cases, it may progress to acropachy, a condition characterized by deformities of the fingers and toes.

Graves’ disease is not just a disorder of the young. It can occur at any age, although it is most common in women under 40. However, it is important to note that seniors are not immune. While the overall incidence of Graves’ disease in the general population is about 0.5%, the prevalence increases with age, making the detection and management of the disease crucial for seniors.

Left untreated, Graves’ disease can lead to severe complications such as osteoporosis (bone thinning) and heart disease. Therefore, seniors experiencing any combination of the symptoms mentioned above, especially if they persist, should seek medical attention promptly to rule out Graves’ disease or other serious conditions.
