UNDERACTIVE THYROID

When the thyroid gland doesn't produce enough thyroid hormones, it can lead to a wide range of physical and emotional symptoms. It's important to note that not everyone with hypothyroidism will experience all of these symptoms, and the severity can vary from person to person. Here's a breakdown of the symptoms:

• Weakness: Individuals with hypothyroidism often experience fatigue and weakness, which can affect their energy levels and daily activities.

• Sensitivity to Cold: Hypothyroidism can lead to feeling excessively cold, even in moderate or warm temperatures.

• Constipation: Sluggish bowel movements and constipation are common symptoms of hypothyroidism.

• Dry Skin: Hypothyroidism can cause dry, itchy skin that may be prone to flakiness.

• Weight Gain: Unexplained weight gain or difficulty losing weight is a common symptom of an underactive thyroid.

• Prominence of the Face: Some individuals with hypothyroidism may notice puffiness or facial swelling, particularly around the eyes.

• Hoarseness: Hypothyroidism can affect the voice, leading to hoarseness or changes in vocal quality.

• High Cholesterol: Elevated levels of cholesterol are often seen in individuals with untreated hypothyroidism.

• Pain and Tenderness in Muscles: Muscular aches and pains can be associated with hypothyroidism.

• Pain and Inflammation in Joints: Joint stiffness and discomfort are potential symptoms of an underactive thyroid.

• Irregular Menstruation: Hypothyroidism can lead to changes in menstrual cycles, including irregular periods or heavier menstrual flow.

• Hair Loss: Thinning hair or hair loss, especially from the scalp and eyebrows, is a common symptom.

• Slow Heartbeat: A slow heart rate, known as bradycardia, can occur in hypothyroidism.

• Depression: Hypothyroidism can contribute to mood changes, including symptoms of depression.

• Loss of Memory: Some individuals with an underactive thyroid may experience cognitive changes, such as memory difficulties or "brain fog."

• Swollen Thyroid Gland (Goitre): In some cases, the thyroid gland may become enlarged, leading to a visible or palpable swelling in the neck known as a goitre.

Hypothyroidism is classified into: 

• Primary Hypothyroidism: This is the most common type and occurs when the thyroid gland itself fails to produce enough thyroid hormones. It can be caused by autoimmune conditions like Hashimoto's thyroiditis, where the immune system attacks the thyroid, as well as other factors such as iodine deficiency, thyroid surgery, or radiation therapy.

• Central Hypothyroidism: In this form, the problem lies not in the thyroid gland but in the pituitary gland or hypothalamus in the brain. These glands produce hormones that control the thyroid, and any dysfunction in these areas can lead to decreased thyroid hormone production.

• Subclinical Hypothyroidism: This is a milder form of hypothyroidism where the thyroid hormone levels are slightly lower than normal, but the individual may not show obvious symptoms. Subclinical hypothyroidism can progress to overt hypothyroidism over time.

• Congenital Hypothyroidism: Some infants are born with an underactive thyroid gland, which is called congenital hypothyroidism. Early diagnosis and treatment are crucial to prevent developmental issues.

• Postpartum Hypothyroidism: Some women may develop hypothyroidism after giving birth, known as postpartum hypothyroidism. It is often a temporary condition but requires monitoring and treatment.

• Drug-Induced Hypothyroidism: Certain medications or treatments can interfere with thyroid hormone production, leading to hypothyroidism. Lithium, amiodarone, and certain cancer treatments are examples of drugs that can cause this effect.

Causes for underactive thyroid can include: 

• Autoimmune Disorder (Hashimoto's Thyroiditis): Hashimoto's thyroiditis is one of the most common causes of hypothyroidism. It is an autoimmune condition in which the immune system mistakenly attacks and damages the thyroid gland, leading to reduced thyroid function over time.

• Treatment for Hyperthyroidism: Some treatments for hyperthyroidism, such as radioactive iodine therapy or surgical removal of the thyroid gland (thyroidectomy), can inadvertently result in an underactive thyroid if the treatment is too aggressive or if complications arise.

• Thyroid Surgery: As you mentioned, thyroid surgery carries a risk of damaging or removing too much of the thyroid tissue, leading to permanent hypothyroidism. However, thyroid surgeries are typically performed with the goal of preserving thyroid function whenever possible.

• Radiotherapy: Radiation therapy, particularly when directed at the neck or head area, can damage the thyroid gland and disrupt its hormone production.

• Medications: Certain medications, such as lithium and amiodarone, can interfere with thyroid function and contribute to hypothyroidism.

• Inheritance: A family history of thyroid disorders can increase the risk of developing hypothyroidism. Some individuals may have a genetic predisposition to thyroid problems.

• Insufficiency of the Pituitary Gland: The pituitary gland plays a crucial role in regulating thyroid hormone production. If the pituitary gland is not functioning correctly, it can lead to decreased stimulation of the thyroid gland, resulting in hypothyroidism.

• Iodine Deficiency: Iodine is an essential mineral required for the production of thyroid hormones. In regions with severe iodine deficiency, hypothyroidism can develop. However, iodine deficiency is relatively rare in areas where iodized salt is widely used.

Medical treatment for hypothyroidism typically involves the replacement of the missing thyroid hormones. Levothyroxine is the most commonly prescribed medication for this purpose. Here's some information about Levothyroxine and its use in treating hypothyroidism:

• Levothyroxine (Synthroid, Levoxyl, Tirosint): Levothyroxine is a synthetic form of the thyroid hormone thyroxine (T4). It works by providing the body with the thyroid hormones it lacks, helping to restore normal thyroid function. Levothyroxine is usually taken orally in the form of a tablet.

Here are some key points regarding the use of Levothyroxine for hypothyroidism:

• Individualised Dosage: The dosage of Levothyroxine is typically tailored to each patient's specific needs based on factors such as their age, weight, and the severity of their hypothyroidism.

• Regular Monitoring: After starting treatment with Levothyroxine, it's essential to have regular follow-up appointments with a healthcare provider. This allows for adjustments in the medication dosage if needed to ensure that thyroid hormone levels are within the desired range.

• Consistent Timing: It's important to take Levothyroxine consistently and at the same time each day, typically in the morning, on an empty stomach. Avoid taking it with food or other medications that may interfere with its absorption.

• Monitoring Symptoms: While on Levothyroxine, pay attention to any changes in symptoms. If you experience side effects or notice that your symptoms worsen or don't improve, inform your healthcare provider.

• Lifelong Treatment: In most cases, hypothyroidism requires lifelong treatment with Levothyroxine. It's crucial to continue taking the medication as prescribed to maintain thyroid hormone balance.

• Potential Interactions: Some medications, supplements, and foods can interact with Levothyroxine, affecting its absorption and effectiveness. Inform your healthcare provider of all the medications and supplements you are taking to ensure there are no interactions.

• Pregnancy and Hypothyroidism: Women who are pregnant or planning to become pregnant should work closely with their healthcare provider to manage hypothyroidism, as thyroid hormone requirements may change during pregnancy.

Natural approaches to support thyroid health and manage symptoms of hypothyroidism can be beneficial, but it's essential to consult with a healthcare provider for a comprehensive treatment plan. Here are some natural ideas that might be helpful:

• Iodine-Rich Foods: Iodine is a crucial component of thyroid hormones. Including iodine-rich foods like seaweed, iodized salt, fish, and dairy products in your diet can help support thyroid function. However, be cautious not to consume excessive iodine, as this can have adverse effects.

• Coconut Oil: Some people find that incorporating coconut oil into their diet may support thyroid function. Coconut oil contains medium-chain fatty acids, which can be easily converted into energy by the body.

• Regular Exercise: Engaging in regular physical activity can help boost metabolism and improve overall well-being. Aim for a combination of cardiovascular exercises and strength training to support your thyroid and overall health.

• Gluten-Free Diet: For individuals with autoimmune thyroid conditions like Hashimoto's thyroiditis, adopting a gluten-free diet may be beneficial. There is some evidence to suggest that gluten consumption can exacerbate autoimmune thyroid issues.

• Stress Management: Chronic stress can negatively impact thyroid function. Practising stress-reduction techniques such as meditation, yoga, deep breathing exercises, and mindfulness can help manage stress and support thyroid health.

• Sunlight: Adequate exposure to natural sunlight can help regulate circadian rhythms and support overall health. Spend time outdoors during daylight hours to promote a healthy sleep-wake cycle.

• Nutrient-Rich Diet: Ensure your diet is rich in essential nutrients like zinc and selenium, which are important for thyroid function. Foods like nuts, seeds, lean meats, and seafood can provide these nutrients.

• Avoid Goitrogenic Foods: Some foods, like broccoli, cabbage, cauliflower, and soy, contain goitrogens, which can interfere with thyroid function. Cooking these foods can reduce their goitrogenic effects.
