Top 5 Causes of Your Fatigue

1. Low or high thyroid function (thyroid dysfunction)

The thyroid gland is a butterfly shaped gland located in your neck. Thyroid hormone regulates your metabolism. Fatigue is a major symptom your thyroid is out of balance, it can happen in both hypo and hyperthyroidism. Getting a thorough thyroid panel will help you to determine if this is cause of your fatigue. Ask for the following labs: TSH, Free T3, Free T4, TPO, Thyroid autoantibody, Reverse T3. Also ask for a test of the nutrients that help your thyroid to function better such as: ferritin, vitamin D, B12. If these nutrients are low they are another reason for fatigue.

2. Low or high iron levels (iron dysfunction)

Having too much or too little iron can cause fatigue. Low iron is often referred to as anemia. Often a CBC (complete blood count) is ran to screen for this but by the time this shows up in lab work the person is usually severely anemic. Thus ferritin is a better indicator for the need for iron supplementation because it measures the storage form of iron in the liver. High iron is know as hemochromotosis which is associated with an increase in heart disease and cancer. Many people report a general feeling of “unwell” or “fatigue” making it difficult to diagnose. It is usually caught on routine blood work.

3. Adrenal Fatigue or also known as CUSMASS (Chronic Unpredictable Stress Maladaptive Stress Syndrome)

Adrenal fatigue is associated with intense or prolonged stress or illnesses. When stress levels stay high the adrenals remain in “survival mode” thus triggering blood sugar and insulin imbalances, food cravings, weight gain (especially belly fat), fatigue and sleep disturbances. Often people do not have any obvious signs of physical illness, yet have a general sense of not feeling well.

The following symptoms are commonly seen in people with adrenal fatigue:

  • Poor concentration and/or impaired performance
  • Feeling “tired but wired”
  • High stress and irritability
  • Increased appetite / cravings especially for sugar
  • Sleep disturbances
  • Frequent infections or allergies
  • Morning and evening fatigue
4. Chronic disease and infections

Many people suffer from chronic diseases such as diabetes, asthma, and pain. Also, many people are walking around with unknown chronic infections which can affect mitochondria, decrease energy production thus creating severe fatigue. The most common infections that cause fatigue are the Epstein Barre Virus, candida overgrowth, and lymes disease.

5. Increased intestinal permeability AKA leaky gut

The wall of the intestines is semi-permeable. This means the pores only allow certain things to enter the bloodstream and block other things from entering the bloodstream.

For instance, nutrients are allowed to pass through but toxins and large undigested food particles are blocked.

With increased gut permeability, the pores continue to widen, like getting a larger hole torn in a net. The most common causes of leaky gut are: food sensitivities, infections, stress, medications, and heavy metals. As this happens, the particles that are supposed to be kept out pass through into the bloodstream and then circulate throughout the body. This causes systemic inflammation and leads to an immune reaction. This is a major cause of autoimmune diseases.

Some of the symptoms of leaky gut can include fatigue, food allergies, thyroid issues, skin issues like acne and eczema, digestive symptoms such as bloating, gas and IBS.
