Hypothyroidism is the disease state in humans and animals caused by insufficient production of thyroid hormone by the thyroid gland. Cretinism is a form of hypothyroidism found in infants.
Causes of Hypothyroidism
About three percent of the general population is hypothyroid. Factors such as iodine deficiency or exposure to Iodine-131 (I-131) can increase that risk. There are a number of causes for overt hypothyroidism. Historically, and still in many developing countries, iodine deficiency is the most common cause of hypothyroidism worldwide. In iodine-replete individuals, hypothyroidism is mostly caused by Hashimoto’s thyroiditis, or by a lack of the thyroid gland or a deficiency of hormones from either the hypothalamus or the pituitary.
Hypothyroidism can result from postpartum thyroiditis, a condition that affects about 5% of all women within a year after giving birth. The first phase is typically hyperthyroidism. Then, the thyroid either returns to normal or a woman develops hypothyroidism. Of those women who experience hypothyroidism associated with postpartum thyroiditis, one in five will develop permanent hypothyroidism requiring life-long treatment.
Hypothyroidism can also result from sporadic inheritance, sometimes autosomal recessive.
Hypothyroidism is also a relatively common hormone disease in domestic dogs, with some specific breeds having a definite predisposition.
Temporary hypothyroidism can be due to the Wolff-Chaikoff effect. A very high intake of iodine can be used to temporarily treat hyperthyroidism, especially in an emergency situation. Although iodine is substrate for thyroid hormones, high levels prompt the thyroid gland to take in less of the iodine that is eaten, reducing hormone production.
Hypothyroidism is often classified by the organ of origin:
|Primary||thyroid gland||The most common forms include Hashimoto’s thyroiditis (an autoimmune disease) and radioiodine therapy for hyperthyroidism.|
|Secondary||pituitary gland||Occurs if the pituitary gland does not create enough thyroid stimulating hormone (TSH) to induce the thyroid gland to produce enough thyroxine and triiodothyronine. Although not every case of secondary hypothyroidism has a clear-cut cause, it is usually caused by damage to the pituitary gland, as by a tumor, radiation, or surgery.|
|Tertiary||hypothalamus||Results when the hypothalamus fails to produce sufficient thyrotropin-releasing hormone (TRH). TRH prompts the pituitary gland to produce thyrotropin (TSH). Hence may also be termed hypothalamic-pituitary-axis hypothyroidism.|
General psychological associations
Hypothyroidism can be caused by lithium-based mood stabilizers, usually used to treat bipolar disorder(previously known as manic depression).
In addition, patients with hypothyroidism and psychiatric symptoms may be diagnosed with:
- atypical depression (which may present as dysthymia)
- bipolar spectrum syndrome (including bipolar I or bipolar II disorder, cyclothymia, or premenstrual syndrome)
- inattentive ADHD or sluggish cognitive tempo
Symptoms of Hypothyroidism
In adults, hypothyroidism is associated with the following symptoms:
- Poor muscle tone (muscle hypotonia)
- Cold intolerance, increased sensitivity to cold
- Muscle cramps and joint pain
- Thin, brittle fingernails
- Thin, brittle hair
- Dry, itchy skin
- Weight gain and water retention.
- Bradycardia (low heart rate: less than sixty beats per minutes)
- Slowed speech and a hoarse, breaking voice. Deepening of the voice can also be noticed.
- Dry puffy skin, especially on the face
- Thinning of the outer third of the eyebrows
- Abnormal menstrual cycles
- Low basal body temperature
Less common symptoms
- Heat intolerance, increased sensitivity to heat
- Impaired memory
- Impaired cognitive function (brain fog) and inattentiveness
- Urticaria (hives)
- Migraine headache
- A slow heart rate with ECG changes including low voltage signals. Diminished cardiac output and decreased contractility.
- Reactive (or post-prandial) hypoglycemia
- Pericardial effusions may occur.
- Sluggish reflexes
- Hair loss
- Anemia caused by impaired hemoglobin synthesis (decreased EPO levels), impaired intestinal iron and folate absorption or B12 deficiency from pernicious anemia
- Anxiety/panic attacks
- Difficulty swallowing
- Shortness of breath with a shallow and slow respiratory pattern.
- Impaired ventilatory responses to hypercapnia and hypoxia.
- Increased need for sleep
- Osteopenia or Osteoporosis
- Irritability and mood instability
- Yellowing of the skin due to impaired conversion of beta-carotene to vitamin A
- Impaired renal function with decreased GFR.
- Thin, fragile or absent cuticles
- Elevated serum cholesterol
- Acute psychosis (myxedema madness) is a rare presentation of hypothyroidism
- Decreased libido
- Decreased sense of taste and smell (late, less common symptoms)
- Puffy face, hands and feet (late, less common symptoms)
Hypothyroidism in pediatric patients was previously classified as Cretinism, and can cause the following symptoms:
- short stature
- mental retardation if present at birth, and untreated.
The severity of hypothyroidism varies widely. Some have few overt symptoms, others with moderate symptoms can be mistaken for having other diseases and states. Advanced hypothyroidism may cause severe complications including cardiovascular and psychiatric myxedema.
Diagnostic testing for Hypothyroidism
To diagnose primary hypothyroidism, many doctors simply measure the amount of Thyroid-stimulating hormone (TSH) being produced by the pituitary gland. High levels of TSH indicate that the thyroid is not producing sufficient levels of Thyroid hormone (mainly as thyroxine (T4) and smaller amounts of triiodothyronine (T3)). However, measuring just TSH fails to diagnose secondary and tertiary forms of hypothyroidism, thus leading to the following suggested blood testing if the TSH is normal and hypothyroidism is still suspected:
- free triiodothyronine (fT3)
- free levothyroxine (fT4)
- total T3
- total T4
Additionally, the following measurements may be needed:
- 24 hour urine free T3;
- antithyroid antibodies — for evidence of autoimmune diseases that may be damaging the thyroid gland;
- serum cholesterol — which may be elevated in hypothyroidism;
- prolactin — as a widely available test of pituitary function;
- testing for anemia, including ferritin.
Treatment of Hypothyroidism
Hypothyroidism is treated with the levorotatory forms of thyroxine (L-T4) and triiodothyronine (L-T3). Both synthetic and animal-derived thyroid tablets are available and can be prescribed for patients in need of additional thyroid hormone. Thyroid hormone is taken daily, and doctors can monitor blood levels to help assure proper dosing. There are several different treatment protocols in thyroid replacement therapy:
- T4 Only
- This treatment involves supplementation of levothyroxine alone, in a synthetic form. It is currently the standard treatment in mainstream medicine.
- T4 and T3 in Combination
- This treatment protocol involves administering both synthetic L-T4 and L-T3 simultaneously in combination.
- Desiccated Thyroid Extract
- Desiccated thyroid extract is an animal based thyroid extract, most commonly from a porcine source. It is also a combination therapy, containing natural forms of L-T4 and L-T3.
The current standard treatment in thyroid therapy is levothyroxine only, and the American Association of Clinical Endocrinologists (AACE) states that desiccated thyroid hormone, combinations of thyroid hormone, or triiodothyronine should not generally be used for replacement therapy. Nevertheless, there exists some controversy about whether this treatment protocol is optimal, and recent studies have given conflicting results.
Two recent studies comparing synthetic T4 versus synthetic T4 + T3 have shown “clear improvements in both cognition and mood” from combination therapy.  . Another study comparing synthetic T4 and desiccated thyroid extract showed marked improvements in virtually all symptom categories when certain patients were switched from synthetic T4 to desiccated thyroid extract.
However other studies have shown no improvement in mood or mental abilities for those on combination therapy, and possibly impaired well-being from subclinical hyperthyroidism. And, a 2007 metaanalysis of the nine controlled studies so far published found no significant difference in the effect on psychiatric symptoms.
There is also concern among some practitioners about the use of T3 due to its short half life. T3 when used on its own as a treatment results in wide fluctuations across the course of a day in the thyroid hormone levels, and with combined T3/T4 therapy there continues to be wide variation throughout each day.
Subclinical hypothyroidism occurs when thyrotropin (TSH) levels are elevated but thyroxine (T4) and triiodothyronine (T3) levels are normal. In primary hypothyroidism, TSH levels are high and T4 and T3 levels are low. Endocrinologists are puzzled because TSH usually increases when T4 and T3 levels drop. TSH prompts the thyroid gland to make more hormone. Endocrinologists are unsure how subclinical hypothyroidism affects cellular metabolic rates (and ultimately the body’s organs) because the levels of the active hormones are adequate. Some have proposed treating subclinical hypothyroidism with levothyroxine, the typical treatment for overt hypothyroidism, but the benefits and the risks are unclear. Reference ranges have been debated as well. The American Association of Clinical Endocrinologists (ACEE) supports a narrower TSH range, especially when the person has clinical signs of thyroid disease. This reference range may reduce the risks of goiter, thyroid nodules, thyroid cancer, and overt hypothyroidism, but remains controversial. There is always the risk of overtreatment and hyperthyroidism. Some studies have suggested that subclinical hypothyroidism does not need to be treated. A meta-analysis by the Cochrane Collaboration found no benefit of thyroid hormone replacement except “some parameters of lipid profiles and left ventricular function”. A more recent metanalysis looking into whether subclinical hypothyroidism may increase the risk of cardiovascular disease, as has been previously suggested, found a possible modest increase and suggested further studies be undertaken with coronary heart disease as a end point “before current recommendations are updated”.
Homeopathy Treatment for Hypothyroidism
Keywords: homeopathy, homeopathic, treatment, cure, remedy, remedies, medicine
Homeopathy treats the person as a whole. It means that homeopathic treatment focuses on the patient as a person, as well as his pathological condition. The homeopathic medicines are selected after a full individualizing examination and case-analysis, which includes the medical history of the patient, physical and mental constitution, family history, presenting symptoms, underlying pathology, possible causative factors etc. A miasmatic tendency (predisposition/susceptibility) is also often taken into account for the treatment of chronic conditions. A homeopathy doctor tries to treat more than just the presenting symptoms. The focus is usually on what caused the disease condition? Why ‘this patient’ is sick ‘this way’. The disease diagnosis is important but in homeopathy, the cause of disease is not just probed to the level of bacteria and viruses. Other factors like mental, emotional and physical stress that could predispose a person to illness are also looked for. No a days, even modern medicine also considers a large number of diseases as psychosomatic. The correct homeopathy remedy tries to correct this disease predisposition. The focus is not on curing the disease but to cure the person who is sick, to restore the health. If a disease pathology is not very advanced, homeopathy remedies do give a hope for cure but even in incurable cases, the quality of life can be greatly improved with homeopathic medicines.
The homeopathic remedies (medicines) given below indicate the therapeutic affinity but this is not a complete and definite guide to the homeopathy treatment of this condition. The symptoms listed against each homeopathic remedy may not be directly related to this disease because in homeopathy general symptoms and constitutional indications are also taken into account for selecting a remedy. To study any of the following remedies in more detail, please visit the Materia Medica section at Hpathy.
None of these medicines should be taken without professional advice and guidance.
