Has your get up and go gone?
We offer custom Thyroid, compounded T3/T4 & Desiccated Thyroid. Consults are inclinic or virtual anywhere in Canada including Nova Scotia, Yukon & New Brunswick. Your thyroid is a small butterfly-shaped gland that produces hormones that influence essentially every organ, tissue and cell in your body.
Hypothyroidism (under active thyroid) affects some 80 percent of people with thyroid disease. Symptoms of hypothyroidism include fatigue, forgetfulness, depression, constipation, and changes in weight and appetite.
Thyroid-related fatigue begins to appear when you cannot sustain energy long enough, especially when compared to a past level of fitness or ability. If your thyroid foundation is weak, sustaining energy output is difficult. You will notice you just don’t seem to have the energy to do the things you used to be able to do.
The butterfly-shaped thyroid gland is located in the front of your neck and wraps partially around the windpipe. The gland is responsible for making thyroid hormones that control the metabolism of all cells in your body. If the thyroid overproduces hormones, you can have a condition called hyperthyroidism. This condition commonly causes symptoms such as a forceful and rapid heart beat, insomnia, sudden weight loss, breathlessness, nervousness, irritability, sweating, and frequent bowel movements.
Many people can also suffer from different degrees of low or under active thyroid function, called hypothyroidism. Symptoms of a thyroid gland producing too little thyroid hormone can include a slow metabolism, listlessness, lowered body temperature, weight gain, constipation, muscle soreness, feeling cold, fatigue, depression, high cholesterol and homocysteine, painful joints, dry skin, and hair loss.
There are two types of thyroid hormones: Thyroxine (T4) and Triiodothyronine (T3). T4 is inactive and kept in reserve; T3 is the active hormone. Thyroid hormones control the growth, differentiation, and metabolism of each cell in our body. They also control how fast our body uses the fuel that we consume, particularly carbohydrates and fat.1 This helps to regulate our body temperature and fat percentage. About 80% of thyroid hormone production is T4, the inactive thyroid hormone that is typically held in reserve by the body. T3 makes up only 20% of thyroid hormone production,5 but it is the active hormone that the body uses to function. T4 is converted into T3 when thyroid hormone is needed.
The release of the thyroid hormones is controlled by thyroid stimulating hormone (TSH), which is produced in the pituitary gland. Low circulating levels of thyroid hormone are detected by the hypothalamus, which then instructs the pituitary to release TSH. When sufficient amounts are released, the hypothalamus communicates with the pituitary to stop or slow down. Because of this complicated feedback loop, high levels of TSH in the blood often mean the pituitary is trying to stimulate thyroid hormone production, but the thyroid gland is not responding. This condition is known as hypothyroidism.
How do you know if your thyroid is not working properly?
Your body will likely let you know, and fatigue is the most common sign, followed by depression and muscle weakness. Along with the symptoms above, signs of an under active thyroid also include:
· Difficulty losing weight despite proper diet and exercise
· Sensitivity to cold
· Dry, rough or scaly skin, and dry, tangled hair
· Hair loss, particularly from the outer part of your eyebrows
· Brittle nails, cold hands and feet
Benefits of the Thyroid
· Regulates temperature, metabolism & cerebral function
· Increases energy, body temperature, and warmth
· Increases fat breakdown, resulting in decreased weight and lower cholesterol
· Protects against cardiovascular ailments 3, 6
· Improves cerebral metabolism
· Supports cognitive function 7
· Relieves symptoms of thin hair, dry skin & brittle nails
