If not detected early and managed effectively, it can lead to a range of complications that can be detrimental to your systemic body functions. So, in this comprehensive blog, we will discuss everything, from the causes and symptoms of hashimoto's thyroiditis to its available treatment options and diet plan to follow. Therefore, stay with this guide to clear all your doubts.

What Is Hashimoto's Thyroiditis?

Hashimoto's thyroiditis, or hashimoto's disease, is a condition affecting your thyroid gland, a small butterfly-shaped organ in your neck that regulates metabolism and energy levels. The disease is named after Dr. Hakaru Hashimoto, who first described it in 1912.

Thyroid balance is vital for your body's proper functioning. But, this autoimmune disorder (which means that your immune system mistakenly attacks your body's own cells) causes inflammation and gradual destruction of your thyroid tissue, disturbing the normal functioning of the body. As a result of this inflammation, your thyroid glands are unable to produce sufficient thyroid hormones that are crucial for you as they influence your heart rate, digestion, and overall well-being. This causes an underactive thyroid or hypothyroidism, further leading to complications such as heart problems, infertility, and joint pain, among others.  

How Common is Hashimoto's Thyroiditis?

Hashimoto's thyroiditis stands as one of the most common autoimmune disorders globally. The prevalence of this disorder varies based on geographical region but has an estimated overall rate of 0.3-1.5 cases per 1000 persons in the world. Moreover, its prevalence is observed to increase with age.

Who Does Hashimoto's Thyroiditis Affect?

Hashimoto's thyroiditis primarily affects women, with a female-to-male ratio of 10:1. It is most commonly diagnosed between the ages of 30 and 50, although it can occur at any age. You may be more susceptible to hashimoto's disease if you have a family history of autoimmune diseases. 

What are the Symptoms of Hashimoto's Thyroiditis?

The symptoms of Hashimoto's Thyroiditis can manifest in different forms. For instance:

• Fatigue: Persistent and unexplained tiredness is a common early symptom of hashimoto's thyroiditis.
• Weight Gain: You may notice gradual weight gain, often accompanied by difficulty in losing weight.
• Intolerance to Cold: Sensitivity to cold temperatures, even in mild conditions, is a frequent complaint.
• Muscle and Joint Pain: Aches and pains in muscles and joints can be indicative of the autoimmune response affecting the thyroid.
• Constipation: Sluggish bowel movements and constipation are also reported symptoms.
• Dry Skin: Skin may become dry and coarse, reflecting the impact on your body's metabolic functions.
• Menstrual Irregularities: Women with hashimoto's thyroiditis may experience irregularities in their menstrual cycles.
• Mood Swings and Depression: Mental health can be affected, leading to mood swings and, in some cases, depression.

How Do You Feel When You Have Hashimoto's?

Living with hashimoto's autoimmune disease can be an overwhelming experience. You will feel a constant lack of energy, making even the simplest tasks feel like a challenging effort. Your body may ache due to muscle weakness, and joint pain can trouble you daily. Moreover, you will struggle to maintain your weight, no matter how hard you try to maintain a healthy lifestyle.

In addition, you may also suffer from cold, dry skin and hair loss, further adding to your distress. The constant fluctuations in hormone levels can lead to psychiatric disturbances and sleep disorders like sleep apnea. You may find it difficult to speak or move properly, accompanied by a reduced ability to remember things. These symptoms can vary in intensity and may fluctuate over time, making it challenging for you to predict how you will feel on any given day.
 

What Causes Hashimoto's Thyroiditis?

The exact cause of an autoimmune response is a grey area, but generally speaking, your body's immune system loses the ability to distinguish between foreign cells and your cells. This generates antibodies against your own thyroid gland tissue. Thus, the primary cause of hashimoto's thyroiditis is an autoimmune response in your body.

Some other causes of hashimoto's thyroiditis and risk factors are as follows:

• There's a familial tendency, suggesting a genetic component in the development of hashimoto's thyroiditis
• Factors like excessive iodine intake or exposure to radiation may contribute to the onset of the disorder.
• Events such as pregnancy or fluctuations in hormone levels can be a direct cause of hashimoto's thyroiditis or increase its risk. 

What are the Complications of Hashimoto's Thyroiditis?

Hashimoto's thyroiditis, if not effectively managed, can lead to a range of complications that adversely affect your body in the long term. For instance:

• Prolonged inflammation caused by the autoimmune response may cause an enlarged thyroid. This can cause hoarseness of the voice and swelling in your neck, even leading to goitre.
• Hashimoto's thyroiditis is associated with a significantly increased occurrence of other autoimmune conditions, such as type 1 diabetes, pernicious anaemia, celiac disease, and adrenal insufficiency, among others.
• If you leave hashimoto's disease untreated, you may face an elevated risk of cardiovascular complications, including heart disease.
• Pregnant women with the condition may experience higher risks of miscarriage, preterm birth, or developmental disorders in the baby.

How is Hashimoto's Thyroiditis Diagnosed?

Diagnosing hashimoto's thyroiditis involves a comprehensive approach that combines clinical evaluation, medical history, and specific laboratory tests.

• Physical examination involves palpating the thyroid for enlargement or the presence of nodules.
• Thyroid function is assessed through a blood test by measuring levels of thyroid hormones T3 and T4, as well as thyroid-stimulating hormone (TSH).

Elevated TSH alongside reduced T3 and T4 levels signifies an underactive thyroid, characteristic of hashimoto's. Additionally, specific antibodies related to thyroid function, such as anti-thyroid peroxidase (TPO) and anti-thyroglobulin (TG), are measured. High levels of these antibodies indicate an autoimmune response targeting the thyroid.

• Imaging studies, particularly thyroid ultrasound, provide a detailed view of the gland's size, structure, and any abnormalities.

Together, these comprehensive tests allow your doctor to establish a precise diagnosis and recommend appropriate treatment for hashimoto's thyroiditis.

What is the Treatment for Hashimoto's Thyroiditis?

Hashimoto's thyroiditis treatment aims at alleviating symptoms, reducing the risk of complications, and optimising thyroid function.

• Hormone Replacement Therapy: Managing hashimoto's thyroiditis typically involves lifelong thyroid hormone replacement therapy. The synthetic thyroid hormone levothyroxine is prescribed to supplement the insufficient hormone production caused by the autoimmune destruction of your thyroid gland. Your healthcare provider will customise the dosage based on your specific needs,
• Lifestyle Modifications: Lifestyle modifications, such as a balanced diet and regular exercise, can complement medical treatment,
• Anti-Inflammatory Medications: Prescribed medications with anti-inflammatory properties may be recommended to manage thyroid gland inflammation. 
• Surgery: In some cases, if a goitre causes discomfort or other complications, surgery might be considered to remove part or all of your thyroid gland. However, this is a less common option and is typically reserved for specific situations.

Side Effects of Levothyroxine

Taking levothyroxine for hashimoto's thyroiditis treatment may lead to side effects like insomnia, increased heart rate, osteoporosis or unintentional weight loss. However, these symptoms often indicate an imbalance in medication dosage. Therefore, adhering to the recommended doses, as prescribed by your doctor, can help manage these side effects, ensuring that the medication effectively restores thyroid hormone levels without causing undue discomfort.

If you experience persistent side effects, seek prompt medical advice for adjustments to your treatment plan.

Is There a Special Diet for People with Hashimoto's Thyroiditis?

Yes, adopting a special diet for hashimoto's can be beneficial. Personalised dietary choices, guided by doctors and nutritionists, play a key role in managing Hashimoto's Thyroiditis.

• Prioritise whole grains, lean proteins (pulses, legumes, lean meats), fruits, vegetables, and low-fat dairy to ensure a well-rounded intake of vitamins and minerals.
• Some individuals with hashimoto's may benefit from reducing or eliminating gluten, found in wheat and other grains, as it can contribute to inflammation.
• Limit iodine-rich foods like iodised salt, as excessive iodine can increase the risk of thyroid issues.
• Include sources of omega-3 fatty acids like flaxseeds, walnuts, and fatty fish for their anti-inflammatory properties.

Can Hashimoto's Disease be Cured?

Hashimoto's disease cannot be cured, but it can be effectively managed with lifelong thyroid hormone replacement therapy and lifestyle adjustments.

Can I Prevent Hashimoto's Thyroiditis?

Preventing Hashimoto's Thyroiditis remains a challenge, given its complex interplay of genetic and environmental factors. However, there are strategies to mitigate the risk and promote your overall thyroid health.

• Balanced Diet: Adopt a nutrient-rich, balanced diet. Evidence suggests that certain nutrients, like selenium and vitamin D, may play a role in thyroid health.
• Iodine Moderation: While iodine is essential for thyroid function, excessive intake can trigger or exacerbate thyroid disorders. Consume iodine in moderation, avoiding excessive use of iodised salt and iodine-rich supplements.
• Stress Management: Chronic stress can impact your immune system. Engage in stress-reducing activities such as yoga, meditation, or deep breathing exercises.
• Regular Exercise: Incorporate regular physical activity into your routine. Exercise has been shown to have positive effects on mood, metabolism, and immune function.
• Adequate Sleep: Prioritise sufficient and quality sleep. Poor sleep can contribute to stress and negatively affect the immune system.
• Avoid Smoking: Smoking is linked to an increased risk of autoimmune thyroid disorders. Quitting or avoiding smoking is advisable.
• Regular Thyroid Check-ups: Routine thyroid function tests, especially if you have a family history of thyroid disorders or autoimmune conditions, can aid in early detection and management of Hashimoto's Thyroiditis.
• Limit Environmental Toxins: Reduce exposure to environmental toxins and pollutants, which may contribute to autoimmune reactions. Use clean household products and be mindful of environmental factors that could affect thyroid health.

What is the Prognosis for Hashimoto's Thyroiditis?

The prognosis for hashimoto's thyroiditis varies from person to person. While there is no curative treatment for hashimoto's disease, the prognosis is generally favourable with proper management.

Lifelong thyroid hormone replacement therapy effectively controls symptoms, and lifestyle adjustments can enhance overall well-being. However, the condition is chronic, and periodic monitoring is essential. So, untreated hashimoto's thyroiditis can lead to hypothyroidism, causing morbidity if not treated with adequate L-thyroxine replacement. Its link to lipid disorders may increase the risk of morbidity from coronary artery disease.

Hashimoto's Thyroiditis During Pregnancy

Hashimoto's thyroiditis during pregnancy poses potential risks for both the mother and the developing fetus. Therefore, pregnant women with this condition may encounter complications such as:

• Preeclampsia
• Gestational diabetes
• An increased likelihood of postpartum haemorrhage
• Pre-term birth
• Miscarriage

Moreover, poorly managed or untreated hashimoto's is associated with developmental concerns for the baby, including intellectual disorders. Therefore, close monitoring of thyroid hormone levels is imperative during pregnancy, as fluctuations can impact both maternal and fetal health. Babies born to mothers with uncontrolled hashimoto's may also face complications such as low birth weight and respiratory distress syndrome.

When Should I See My Healthcare Provider?

If you experience symptoms like constant fatigue, weight gain, or cold sensitivity, consult your doctor promptly, especially if you have a family history of thyroid disorders or autoimmune conditions. Moreover, if you are planning a pregnancy or experiencing specific pregnancy-related hashimoto's symptoms, consult an endocrinologist as soon as possible to reduce the risk of complications for both you and your baby.

Conclusion

Managing hashimoto's thyroiditis requires a proactive approach involving medical guidance, lifestyle adjustments, and consistent monitoring. While the condition is chronic, proper care allows you to lead a fulfilling life with minimised symptoms.
