Graves Disease

Symptoms Of Graves disease 

Graves' disease is an autoimmune disorder that often presents symptoms of hyperthyroidism, along with effects on the eyes and skin. Symptoms can vary over time.

1. Hyperthyroidism symptoms

• Rapid or irregular heartbeat

• Tremors, muscle weakness

• Sleep issues, nervousness

• Weight loss despite normal eating habits

• Excessive sweating, heat intolerance

• Frequent bowel movements

• Enlarged thyroid gland (goitre)
  
  

2. Skin symptoms

• Reddish, thickened skin (Graves' dermopathy)

• Rough skin texture, primarily on the shins

• Mild and painless in most cases
  
  

3. Ophthalmic symptoms

• Eye inflammation or redness

• Tissue swelling

• Gritty, irritated eyes

• Swollen or puffy eyes

• Sensitivity to light

• Eye pressure or pain

• Blurred or double vision

• Protruding or bulging eyes 

Note: About 30% of those with Graves’ disease develop Graves’ ophthalmopathy (GO) because the antibodies that attack the thyroid also attack the eyes.

Causes Of Graves disease

Graves' disease is an autoimmune condition where the immune system overproduces an antibody called thyroid-stimulating immunoglobulin (TSI). Instead of protecting the body, this antibody mistakenly attacks the thyroid gland, causing it to become overactive. As a result, the thyroid produces excessive thyroid hormones, leading to hyperthyroidism.

The exact cause of Graves' disease remains unknown, but certain factors may increase the risk of developing this condition. Further details on these risk factors will be discussed in the next segment.

Risk Factors For Graves disease

Several factors contribute to the risk of developing Graves' disease. These include:

Demographic factors:

• Gender: Women are at a significantly higher risk compared to men.

• Age: Individuals aged 30 or above are more susceptible.

• Postpartum period: Women are particularly vulnerable after childbirth.

Genetic factors:

• Family history: A family history of Graves' disease, Hashimoto's disease, or other autoimmune disorders increases risk.

• Down syndrome: Children with Down syndrome are at a higher risk.

• DiGeorge syndrome: Children with DiGeorge syndrome are also more susceptible.

Environmental factors:

• Infections: Bacterial and viral infections may trigger autoimmune responses.

• Iodine exposure: Elevated levels of iodine can predispose individuals.

• Smoking: Tobacco use increases the risk.

• Stress: Significant stress can trigger the onset.

• Highly Active Antiretroviral Therapy (HAART): Individuals undergoing this treatment face increased risk.

Autoimmune conditions:

• Rheumatoid Arthritis

• Type 1 Diabetes

• Autoimmune Gastritis

• Vitiligo

Diagnosis Of Graves disease

Graves' disease diagnosis involves a series of steps:

1. Medical history and physical examination

The doctor assesses symptoms, medical history, and family background. Physical exams may reveal signs like an enlarged thyroid gland (goitre), eye changes (such as bulging eyes or eyelid retraction), and skin changes.

2. Thyroid function tests

Blood tests measure levels of thyroid hormones (T4 and T3) and thyroid-stimulating hormone (TSH). In Graves' disease, T4 and T3 levels are typically high, while TSH levels are low or undetectable due to excessive thyroid hormone production.

3. Thyroid antibody tests

Blood tests detect specific antibodies associated with Graves' disease, confirming its autoimmune nature such as thyroid-stimulating immunoglobulins (TSI) or thyroid peroxidase antibodies (TPOAb). 

4. Radioactive Iodine Uptake (RAIU) test

The radioactive iodine uptake test evaluates the quantity of iodine absorbed by your thyroid gland from your blood to produce thyroid hormones. Elevated iodine uptake may indicate the presence of Graves' disease. 

5. Thyroid Ultrasonogram with doppler

This imaging technique identifies increased blood flow in the thyroid caused by Graves’ disease. It may be preferred over RAIU during pregnancy or breastfeeding.

6. T3/T4 ratio or FT3/FT4 ratio

Ratios exceeding specific thresholds can suggest Graves' disease, providing additional diagnostic insight into the condition's hormonal profile and helping differentiate it from other thyroid disorders.

7. Complete blood tests

To check for related conditions like anemia, liver damage, hypercalcemia, and lipid profile changes.

7. Imaging tests

• Ultrasonography: Preferred over scintigraphy to avoid radiation. Shows an enlarged, hyperechoic, hypervascular thyroid gland.
  
  
• Scintigraphy: Displays uniform isotope uptake and diffuse enlargement of thyroid lobes. Helps in identifying non-autoimmune causes of hyperthyroidism, such as an autonomous 'hot' nodule.
  
  
• CT or MRI of orbits: These imaging tests can help diagnose Graves orbitopathy in patients who show symptoms related to the eyes but don't have an overactive thyroid.

3. Radioactive Iodine Therapy (Radioiodine Ablation)
This treatment involves taking radioactive iodine orally, which targets and destroys overactive thyroid tissue, reducing hormone production.

Note: This therapy is generally used when medications are ineffective or if there's a risk of symptoms returning. It often leads to hypothyroidism, which can be managed with daily thyroid hormone pills.

4. Thyroidectomy (Surgery)
In cases where medications and radioactive iodine are not suitable, surgery to remove part or all of the thyroid gland may be recommended. This is often preferred for large goitres, compressive symptoms, suspected thyroid cancer, or severe Graves' orbitopathy.

Note: Post-surgery, you may develop hypothyroidism, requiring lifelong thyroid hormone replacement. Your doctor will monitor your thyroid hormone levels and adjust your medication as necessary.

II. Managing Graves' Orbitopathy (GO)

For Mild Cases

• Eye care: Use eye drops for dry, gritty eyes and consider taping eyelids shut or using an eye mask at night if they don't fully close.

• Head positioning: Elevate your head while sleeping to reduce swelling.

• Sun protection: Wear sunglasses to alleviate light sensitivity.

• Vision aids: Special lenses may help with double vision.

• Eye relief: Apply artificial tears or lubricating ointment to relieve dryness and use cool compresses to reduce irritation and swelling.

• Lifestyle adjustments: Quit smoking and incorporate regular exercise to lower stress levels.

For Moderate to Severe Cases

• Glucocorticoid therapy: Use steroids to decrease inflammation and swelling around the eyes.

• Orbital decompression surgery: Enlarges the eye socket to reduce bulging and pressure on the eyes, improving function and appearance.

• Radiation therapy: Targets specific eye tissues affected by GO, used when other treatments are ineffective or not suitable.

• Immunotherapy: Rituximab may be prescribed for severe cases where other treatments have not been effective, targeting specific immune cells involved in the disease.
