Know your symptoms

Hypothyroidism is more common than hyperthyroidism. 60% of those who suffer from a thyroid disorder are unaware of their condition.

Hypothyroidism (Underactive Thyroid) occurs when the thyroid gland is not producing a sufficient level of thyroxine (T4) and triiodothyronine (T3).

  • Weight gain
  • Fatigue or feeling tired all the time
  • Slow pulse or heart rate
  • Hair loss or thinning
  • Poor tolerance of the cold
  • Depression
  • Dry, coarse or thickened skin
  • Constipation
  • Hand tingling or pain (carpal tunnel syndrome)
  • Irregular period or low sex drive
  • Muscle cramps
  • Impaired memory

Hyperthyroidism (Overactive Thyroid) occurs when the thyroid gland produces an excessive level of thyroxine (T4) and triiodothyronine (T3).

  • Weight loss
  • Fatigue or feeling tired all the time
  • Increase or rapid heart rate
  • Tremors (usually in the hands)
  • Heat intolerance or excessive sweating
  • Difficulty sleeping
  • Excessive sweating or fever
  • Frequent bowel movements or diarrhea
  • Anxiety
  • Irregular period
  • Low sex drive
  • Enlarged thyroid gland (goiter)
  • Eye condition related to hyperthyroidism

Common causes of hypothyroidism

Hashimoto's thyroiditis

Hashimoto's thyroiditis is the leading cause of hypothyroidism. It causes inflammation in the thyroid which hinders the production of T4 and T3.

Genetic defects

Damaged genes that regulate thyroid function may stunt hormone production.

Gender

Women are 5-8 times more likely to suffer from hypothyroidism than men.

Drugs

Medications and performance-enhancing drugs may affect the ability of the thyroid to produce T4 and T3 naturally.

Common causes of hyperthyroidism

Graves' Disease

Graves Disease is the leading cause of hyperthyroidism. It is an autoimmune disorder in which the thyroid produces too much T4 causing antibodies to attack the thyroid.

Family history

Autoimmune diseases tend to run in families so you are at a higher risk of suffering from hyperthyroidism if a family member does.

Gender

Women are 5-8 times more likely to suffer from hyperthyroidism than men.

Plummer's Disease

Plummer's Disease or goiter occurs when there is a marked growth or swelling of the thyroid gland resulting in the overproduction of thyroxine (T4) and triiodothyronine (T3).

Diagram of the thyroid gland

The thyroid gland is a butterfly-shaped organ located at the base of the neck. It is made of two halves, called lobes, that lie along the windpipe (trachea) and are joined together by a narrow band of tissues known as the isthmus.

What Does Your Thyroid Do?

The thyroid gland is part of the endocrine system and is a powerhouse for all cell functions. It produces, stores and releases hormones such as (T3) and thyroxine (T4) into the bloodstream that influences every organ in the body.

Functions of the thyroid gland:

  • Regulating the body's metabolic rate and digestion
  • The production of calcium for healthy bones
  • The development of the nervous system
  • Regulating heart rate
  • Controlling body temperature
  • Maintaining healthy cholesterol levels
  • Muscle control
  • Controlling mood and energy levels
  • Maintaining healthy hair growth

How Does Your Thyroid Regulate Hormones?

The pituitary gland controls thyroid function. It is a small gland the size of a peanut, located at the base of the brain. The pituitary gland produces Thyroid Stimulating Hormone (TSH) which controls the amount of T3 and T4 released by the thyroid gland.

High levels of TSH will result in a reduction of T3 and T4, whereas low levels of TSH can lead to an increased production of T3 and T4 by the thyroid gland.

  • Hyperthyroidism or overactive thyroid occurs when the thyroid gland produces an excessive level of thyroxine (T4) and triiodothyronine (T3).

  • Hypothyroidism or under-active thyroid occurs when the gland does not secrete enough thyroxine (T4) and triiodothyronine (T3).

The Side Effects of Hypothyroidism

  • High blood pressure
  • Irregular periods
  • Infertility
  • Slower digestion
  • Bloating
  • Heartburn
  • Weight gain
  • Loss of hair from the scalp, face, and body
  • The skin may dry out, thicken or become scaly
  • Mental fatigue or brain fog
  • Depression

The Side Effects of Hyperthyroidism

  • The skin may become smooth, moist and warm
  • Blurred vision or visual sensitivity as a result of Graves' disease
  • Irritability or restlessness
  • Anxiety
