fatigue

diseases conditions and symptoms

Have you ever felt tired, sluggish and have trouble losing weight? These symptoms may be caused by low levels of free T3. Understanding what free T3 is and how it affects your body can help you take action and get back on track to feel your best.

What is free T3?

Free T3 is a thyroid hormone that plays a vital role in regulating metabolism, energy levels, and body temperature. It is produced by the thyroid gland, which is located in the neck. Free T3 is the active form of the hormone that the body can use, while Total T3 includes both active and inactive forms.

Symptoms associated with low free T3

  • Fatigue
  • Weight gain or difficulty losing weight
  • Hair loss
  • Dry skin
  • Cold intolerance
  • Constipation
  • Depression or mood swings

Possible causes of low free T3

There are several possible causes of low Free T3 levels, including:

Hypothyroidism

This is a condition where the thyroid gland does not produce enough thyroid hormone. It can be caused by an autoimmune disorder, radiation treatment, or surgery. A medical doctor who specializes in endocrinology can help diagnose and treat this condition.

Thyroiditis

This is an inflammation of the thyroid gland that can cause it to release too little thyroid hormone. It can be caused by a viral infection or an autoimmune disorder. A medical doctor who specializes in endocrinology can help diagnose and treat this condition.

Certain medications

Certain medications can interfere with the production or conversion of thyroid hormone, leading to low Free T3 levels. These medications include lithium, amiodarone, and glucocorticoids.

Nutrient deficiencies

 A lack of iodine, selenium, or zinc can affect thyroid function and lead to low Free T3 levels.

Herbal and natural treatments

There are several herbal and natural treatments that may help improve thyroid function and increase Free T3 levels. Some of these include:

Ashwagandha (Withania somnifera)

 This herb is known to improve thyroid function and reduce stress. It may also help improve mood and energy levels.

Coleus forskolii (Coleus forskohlii)

This herb may increase thyroid hormone levels and improve metabolism. It may also help with weight loss.

Kelp (Laminaria spp.)

This seaweed is a good source of iodine, which is important for thyroid function.

Suggestions for Changing Bad Living Habits

  • Reduce stress: Stress can interfere with thyroid function and lead to low Free T3 levels. Practice stress-reducing activities such as yoga, meditation, or deep breathing exercises.
  • Exercise regularly: Regular exercise can help improve thyroid function and metabolism. Aim for at least 30 minutes of exercise per day.
  • Eat a balanced diet: A diet that is rich in fruits, vegetables, and whole grains can provide important nutrients for thyroid function. Avoid processed foods and excess sugar.
  • Get enough sleep: Lack of sleep can affect thyroid function and metabolism. Aim for 7-8 hours of sleep per night.

Nutritional advice

A well-balanced diet that is rich in nutrients can help support thyroid function and increase Free T3 levels. Some important nutrients for thyroid health include:

  • Iodine: Found in seaweed, fish, and iodized salt
  • Selenium: Found in Brazil nuts, seafood, and supplements
  • Zinc: Found in oysters, beef, and pumpkin seeds
  • Iron: Found in red meat, poultry, and beans
  • Vitamin D: Found in fatty fish, egg yolks, and supplements

It is important to note that excessive amounts of certain nutrients, such as iodine, can also be harmful to thyroid function. It is recommended to consult with a healthcare professional or registered dietitian for personalized nutrition advice.
