Graves Disease: Causes, Symptoms and Treatment

What is Grave’s Disease?

Grave's Disease is a health condition where the immune system mistakenly attacks the thyroid gland, which is a gland that produces important hormones in our body. This attack causes the thyroid gland to produce too much hormone, resulting in a condition called hyperthyroidism. Grave’s disease is the most common cause of Hyperthyroidism. People with Grave's Disease may experience weight loss, anxiety, trembling, and heart palpitations. It is more common in women and can happen at any age, but is usually found in people under 40 years old. If left untreated, it can cause severe complications.

Who is affected by Grave’s Disease?

Grave's Disease commonly affects women more than men, especially those aged between 30 to 60 years old. However, it can occur in anyone, regardless of gender or age. It is more common in people particularly those with certain genes on the 6^th chromosome, but external factors can also contribute to its development.

What causes Grave’s Disease?

Grave's Disease is caused by a problem with the immune system where the body produces antibodies that mistakenly attack the thyroid gland. The primary cause of the disease is the production of antibodies that are known as Thyroid Stimulating Immunoglobulins or TSIs that specifically target and bind to Thyrotropin Receptors present in the thyroid gland. This leads to the thyroid gland producing too much thyroid hormone, causing hyperthyroidism. There are several genes identified which when influenced by certain environmental and external factors lead to the development of Grave’s Disease, as well as other autoimmune diseases affecting multiple organs.

Are there any factors that increase the risk of Grave’s Disease?

Yes, there are several factors that increase the risk of developing Grave’s Disease, including:

• Gender: Women are more likely to develop Grave’s Disease than men.
• Age: The disease often develops between the ages of 20 and 40.
• Genetics: A family history of autoimmune disorders increases the risk of developing Grave’s Disease.
• Smoking: Smokers are more likely to develop the disease.
• Stress: Stressful life events can trigger the onset of Grave’s Disease.
• Pregnancy: Women who have had a baby in the past year are more likely to develop the disease.
• Other autoimmune diseases: the presence of other autoimmune diseases may influence the development of Grave’s Disease.

Are there any triggers for Grave’s Disease?

Yes, there are several triggers that can lead to the development of Grave's Disease. The most common trigger is a problem with the immune system, where the body produces antibodies that mistakenly attack the thyroid gland. This can be triggered by external factors such as smoking, stress, pregnancy, and infections. Certain medications, such as iodine-containing drugs and interferon, can also trigger the disease in some people. In rare cases, trauma to the eye can trigger the condition, leading to a condition called Graves' ophthalmopathy.

What are the symptoms of Grave’s Disease?

Grave's Disease can cause a variety of symptoms due to the overproduction of thyroid hormones. Some common symptoms include weight loss, anxiety, tremors, rapid heartbeat, sweating, and heat intolerance. Additionally, some people may experience changes in their eyes, such as bulging, redness, or vision changes, due to a condition called Graves' ophthalmopathy. In severe cases, people with Grave's Disease may experience heart problems, bone loss, and other serious complications. It is important to see a doctor if you experience any of these symptoms.

How is Grave’s Disease Diagnosed?

Here are the common steps a doctor takes to diagnose Grave's Disease:

• Physical examination: The doctor will examine the patient for any physical signs of hyperthyroidism, such as a rapid heartbeat or enlarged thyroid gland.
• Blood tests: Blood tests are done to measure the levels of thyroid hormones and thyroid-stimulating immunoglobulin (TSI) antibodies.
• Radioactive iodine uptake (RAIU) test: This test helps to determine the activity level of the thyroid gland. The patient is given a small dose of radioactive iodine, and a special camera is used to measure how much of it is taken up by the thyroid gland.
• Thyroid ultrasound: An ultrasound of the thyroid gland can help to determine if it is enlarged or if there are any nodules present.
• Fine-needle aspiration (FNA) biopsy: If the ultrasound reveals any nodules, a biopsy may be done to determine if they are cancerous or benign.
• Eye exam: An eye exam is done to check for signs of Graves' ophthalmopathy, which is a common complication of the disease.
• The results of these tests, along with the patient's symptoms and medical history, can help the doctor to make an accurate diagnosis of Grave's Disease.

What is the treatment for Grave’s Disease?

Here are some common treatments for Grave's Disease:

• Medications: Anti-thyroid medications like methimazole or carbimazole or propylthiouracil can be prescribed to lower the production of thyroid hormones. Beta-blockers like propranolol may also be given to help manage symptoms like rapid heartbeat and tremors.
• Radioactive iodine therapy: This treatment involves taking a capsule or liquid containing radioactive iodine, which is taken up by the thyroid gland and destroys some of the thyroid cells. This treatment can result in hypothyroidism, so it's important to be monitored by a doctor after treatment.
• Surgery: In some cases, surgery may be recommended to remove part or all of the thyroid gland. This is usually only done if other treatments are not effective or if there is a large goiter that is causing problems.
• Eye treatments: If the patient is experiencing eye problems related to Grave's Disease, treatments like corticosteroids, orbital radiotherapy, or surgery may be recommended.

The treatment plan will depend on the severity of the patient's symptoms and the extent of the disease. Close monitoring by a doctor is important to ensure that the treatment is effective and to monitor for any potential complications.

Can Grave’s Disease be prevented?

Grave's Disease cannot be prevented as it is an autoimmune disease that is caused by genetic and environmental factors that are not completely understood. However, there are some ways to reduce the risk of developing the disease or to manage the symptoms:

• Avoid smoking: Smoking has been shown to increase the risk of developing Grave's Disease, so avoiding smoking or quitting smoking may help reduce the risk.
• Manage stress: Stress has been linked to autoimmune disorders, so managing stress through practices like meditation, exercise, or therapy may help reduce the risk of developing Grave's Disease.
• Get regular check-ups: Regular check-ups with a doctor can help identify any potential thyroid problems early on and allow for prompt treatment.
• Manage other autoimmune diseases: If the patient has other autoimmune diseases, managing them effectively may help reduce the risk of developing Grave's Disease or other autoimmune disorders.
• Follow a healthy lifestyle: Eating a balanced diet, getting regular exercise, and getting enough sleep can all help support overall health and may reduce the risk of developing autoimmune disorders.

What are the complications of Grave’s Disease?

Complications of Grave's Disease may include:

• Thyroid Eye Disease: This is a condition where the muscles and tissues around the eyes become inflamed and swollen, causing the eyes to protrude or become dry and irritated.
• Thyroid Storm: This is a rare but potentially life-threatening complication of Grave's Disease that occurs when the thyroid hormone levels become extremely high, leading to a rapid heartbeat, high fever, and other symptoms.
• Osteoporosis: High levels of thyroid hormones can lead to bone loss, increasing the risk of osteoporosis and fractures.
• Cardiovascular Problems: Grave's Disease can increase the risk of heart problems, including high blood pressure, heart failure, and abnormal heart rhythms.
• Pregnancy Complications: Pregnant women with Grave's Disease may have an increased risk of miscarriage, preterm delivery, and other complications.
• Thyroid Cancer: In rare cases, Grave's Disease can lead to the development of thyroid cancer.

It is important to receive prompt and appropriate treatment for Grave's Disease to help prevent or manage these complications.

Can Grave’s Disease come back?

Yes, Grave's Disease can recur or come back after treatment. In fact, it is common for the disease to return in some people. The risk of recurrence may depend on various factors such as age, gender, family history, and the severity of the initial episode. It is important to continue regular follow-up appointments with a healthcare provider after treatment to monitor for any signs of recurrence and adjust the treatment plan as necessary.

Frequently Asked Questions

Q) What are the 3 main symptoms of Grave’s Disease?
