360 degree about hypothyroidism

There are Thyroid imbalances and then there's Hypothyroidism.
Now you may be wondering, what is the difference between the two?

Thyroid imbalances are any disruption in the normal functioning of the thyroid gland, which plays a crucial role in regulating metabolism, energy production, and overall bodily functions.
These imbalances can manifest as either hyperthyroidism or hypothyroidism, each characterised by distinct symptoms and effects on the body. Hyperthyroidism on the other hand, occurs when the thyroid gland becomes overactive, leading to an excess production of thyroid hormones. This can result in symptoms such as weight loss, rapid heartbeat, heat intolerance, and nervousness.
Hypothyroidism occurs when the thyroid gland is underactive, producing insufficient thyroid hormones. This can cause symptoms such as fatigue, weight gain, cold intolerance, and depression.

The key difference between thyroid imbalances and hypothyroidism lies in the specific nature of the thyroid dysfunction. Thyroid imbalances encompass a broader spectrum of thyroid disorders, including both hyperthyroidism and hypothyroidism, as well as other conditions such as thyroid nodules and thyroiditis.

Now that we have that out of the way, let's look at what causes Hypothyroidism!
-Chronic stress: Prolonged stress can lead to dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis, affecting thyroid function and contributing to hypothyroidism.
-Ageing: The risk of hypothyroidism increases with age, as the thyroid gland may become less efficient in hormone production over time.
-Pregnancy: Pregnancy-related hormonal changes can impact thyroid function, leading to gestational hypothyroidism, especially in women with pre-existing thyroid disorders or iodine deficiency.
-Environmental factors: Exposure to environmental toxins like perchlorate, found in certain water sources and food products, can interfere with thyroid hormone production and contribute to hypothyroidism.
-Genetic predisposition: A family history of thyroid disorders or specific genetic mutations can increase the likelihood of developing hypothyroidism.
-Dietary factors: Consumption of goitrogenic foods, such as cruciferous vegetables (e.g., broccoli, cabbage, kale), in large amounts can interfere with thyroid hormone synthesis and contribute to hypothyroidism, particularly in individuals with iodine deficiency.
-Viral infections: Certain viral infections, such as Epstein-Barr virus or Coxsackie virus, have been associated with the development of autoimmune thyroiditis and subsequent hypothyroidism.
-Autoimmune diseases: Other autoimmune conditions, such as type 1 diabetes or rheumatoid arthritis, may increase the risk of developing autoimmune thyroiditis and hypothyroidism.
-Pituitary tumours: Benign tumours of the pituitary gland can disrupt the production and release of thyroid-stimulating hormone (TSH), leading to secondary hypothyroidism.
-Radiation exposure: Exposure to ionising radiation, either through medical treatments like radiotherapy or environmental sources like nuclear fallout, can damage the thyroid gland and cause hypothyroidism.
-Chronic illnesses: Certain chronic conditions, such as chronic fatigue syndrome or fibromyalgia, may be associated with alterations in thyroid function and an increased risk of hypothyroidism.
-Nutritional deficiencies: Deficiencies in nutrients like selenium, zinc, and vitamin D can impair thyroid function and contribute to the development of hypothyroidism.
-Hormonal imbalances: Disorders affecting other hormones, such as cortisol or insulin, can indirectly impact thyroid function and contribute to hypothyroidism.
-Excessive iodine intake: While iodine deficiency is a known cause of hypothyroidism, excessive intake of iodine, either through diet or supplements, can also disrupt thyroid function and lead to hypothyroidism, especially in susceptible individuals.
-Smoking: Cigarette smoking has been linked to an increased risk of autoimmune thyroid disease and hypothyroidism, possibly due to its effects on immune function and thyroid hormone metabolism.

Other than these regularly known challenges, we also have specific challenges elaborated upon in scientific papers, which can further cause Hypothyroidism:
-Autoimmune Thyroiditis (Hashimoto's Thyroiditis): An autoimmune condition where the body's immune system attacks the thyroid gland, leading to inflammation and eventual hypothyroidism. (Chakera AJ, Pearce SHS, Vaidya B, BMJ, 2012)
-Iodine Deficiency: Inadequate intake of iodine, an essential nutrient for thyroid hormone synthesis, can result in hypothyroidism, particularly in regions with iodine-deficient soils. (Fuge R, Franklyn JA, Dayan CM, Thyroid, 2018)
-Thyroid Surgery or Radiation Therapy: Surgical removal of the thyroid gland or radiation therapy for thyroid cancer can result in hypothyroidism if the gland is damaged or removed. (Vanderpump MPJ, Clinical Biochemist Reviews, 2011)
-Medications: Certain medications, such as lithium (used to treat psychiatric disorders) or amiodarone (used to treat heart rhythm disorders), can interfere with thyroid hormone production and lead to hypothyroidism. (Chakera AJ, Pearce SHS, Vaidya B, BMJ, 2012)
-Congenital Thyroid Abnormalities: Some infants are born with abnormalities of the thyroid gland, leading to congenital hypothyroidism, which can affect growth and development if not promptly treated. (Alexander EK, Pearce EN, Brent GA, Brown RS, Chen H, Dosiou C, Grobman WA, Laurberg P, Lazarus JH, Mandel SJ, Peeters RP, Sullivan S, Endocrine Reviews, 2017)
-Pituitary Disorders: Dysfunction of the pituitary gland, which controls hormone production in the body, can disrupt the secretion of thyroid-stimulating hormone (TSH), leading to secondary hypothyroidism. (Chakera AJ, Pearce SHS, Vaidya B, BMJ, 2012)
