Why Does Hashimoto’s Cause Fatigue?

Are you often feeling tired and fatigued? If so, you may be wondering why Hashimoto’s disease causes fatigue. In this informative video by Dr. Martin Rutherford, he delves into this topic and explains that the answer lies in your thyroid. The thyroid plays a crucial role in controlling your energy levels, and when it becomes underactive (hypothyroidism) due to Hashimoto’s disease, fatigue is a common symptom. Dr. Rutherford also discusses the importance of proper oxygen, blood sugar levels, and the role of inflammation and oxidative stress in affecting your energy production. If you’re interested in learning more about why Hashimoto’s causes fatigue, this video is a must-watch.

Thyroid and Energy Control

The thyroid plays a crucial role in regulating energy levels in the body. It produces hormones that are responsible for maintaining the metabolic rate, which determines how efficiently the body uses energy. When the thyroid is functioning optimally, it produces enough thyroid hormones to keep the energy levels balanced. However, in the case of Hashimoto’s disease, an autoimmune disorder that affects the thyroid, the production of these hormones is disrupted, leading to fatigue and other symptoms.

The Role of Mitochondria

Mitochondria are cellular structures often referred to as the “energy factories” of the body. They are responsible for producing adenosine triphosphate (ATP), the molecule that provides energy for cellular functions. Mitochondria require various factors to ensure optimal energy production, including proper oxygen supply, blood sugar levels, and the absence of inflammation and oxidative stress. Any disruption to these factors can impair mitochondrial function, leading to decreased energy levels.

Factors Affecting Mitochondrial Energy Production

Various factors can affect mitochondrial energy production, ultimately leading to fatigue in individuals with Hashimoto’s disease. These include:

  • Insufficient oxygen supply: Inadequate oxygen delivery to the mitochondria can impair their ability to produce ATP efficiently, resulting in fatigue.
  • Imbalanced blood sugar levels: Mitochondria rely on a steady supply of glucose to generate ATP. Fluctuations in blood sugar levels can disrupt this process, leading to decreased energy production.
  • Inflammation: Chronic inflammation can disrupt mitochondrial function and impair ATP production, contributing to fatigue.
  • Oxidative stress: High levels of oxidative stress can damage mitochondria and hinder their ability to produce energy effectively.

The Importance of T3

T3 is the active form of thyroid hormone that plays a key role in energy regulation. The thyroid gland produces T4, which is then converted into T3. T3 is responsible for binding to receptors on the mitochondria and initiating the production of ATP. In individuals with Hashimoto’s disease, the autoimmune attack on the thyroid can lead to insufficient production of T3, impacting energy production and resulting in fatigue.

Hyperthyroid and Hypothyroid Effects

Hashimoto’s disease can cause both hyperthyroidism and hypothyroidism. During periods of thyroid inflammation, the damaged thyroid can release an excess of thyroid hormones, leading to hyperthyroid symptoms such as increased heart rate, anxiety, and fatigue. Once the autoimmune attack subsides, the thyroid may become underactive, resulting in hypothyroidism. In this state, fatigue and other symptoms of an underactive thyroid, such as weight gain and depression, become more prominent.

Hashimoto’s Autoimmune Attack

Hashimoto’s disease is characterized by an autoimmune attack on the thyroid gland. The immune system mistakenly identifies the thyroid as a threat and begins to attack it, leading to inflammation and damage to the gland. This ongoing attack can result in intermittent hyperthyroidism and chronic hypothyroidism, both of which contribute to fatigue and other symptoms.

Intermittent Hyperthyroidism

During the autoimmune attack on the thyroid, periods of hyperthyroidism can occur. The damaged thyroid releases an excess of thyroid hormones into the bloodstream, which can lead to symptoms such as fatigue, rapid heartbeat, and anxiety. While this hyperthyroid state is temporary, it can contribute to the overall fatigue experienced by individuals with Hashimoto’s disease.

Chronic Hypothyroidism

As the autoimmune attack subsides, the thyroid gland may become underactive, resulting in chronic hypothyroidism. In this state, the thyroid produces insufficient thyroid hormones, leading to a range of symptoms, including fatigue. The decreased production of T3, the active form of thyroid hormone, impairs energy production and contributes to persistent fatigue.

Impact on Cell Function

The fatigue experienced in Hashimoto’s disease is not limited to a single organ or system. Since the thyroid hormones play a crucial role in regulating metabolism and energy production in every cell of the body, the effects of Hashimoto’s can be widespread. Each cell relies on optimal mitochondrial function to produce energy and carry out its functions. When the thyroid is underactive or not producing enough T3, energy production is impaired at the cellular level, contributing to widespread fatigue.

Cardinal Sign of Fatigue

Fatigue is one of the cardinal signs of Hashimoto’s disease. Due to the impact of thyroid dysfunction on energy production at the cellular level, individuals with Hashimoto’s often experience profound fatigue. This fatigue can be debilitating and significantly affect daily functioning and quality of life.

In conclusion, Hashimoto’s disease causes fatigue due to the disruption of thyroid function and its impact on energy production at the cellular level. The autoimmune attack on the thyroid leads to intermittent hyperthyroidism and chronic hypothyroidism, both of which contribute to fatigue. Proper function of the mitochondria and the availability of T3 are essential for optimal energy production. Understanding the underlying mechanisms of fatigue in Hashimoto’s disease can help in developing effective strategies for managing and improving energy levels in individuals with this condition.
