How to beat chronic fatigue

How to beat chronic fatigue

Chronic fatigue or low energy are very common - we can all feel it for a day or two, a few months, and for some it can persist for years. Hormone changes, stress, a lack of sleep, certain health conditions, lack of exercise and poor diet are all potential causes. We explain the causes of 'long tiredness' and how your diet can help beat fatigue. 

What causes extreme fatigue

Nutrient deficiencies

Nutrient deficiencies are a major cause of tiredness and fatigue. The most common nutrient deficiency relating to tiredness is low Iron, however deficiencies in Iodine and B vitamins, Vitamin C and Magnesium can all have a similar impact.

All these nutrients are needed directly for the energy production cycle known as the 'Krebs cycle'. A deficiency in Iron, B vitamins and Copper can also cause problems with blood cell formation and haemoglobin, the oxygen-carrying part of blood cells, which leads to fatigue.

Viral infections

Viral infections are a common cause of chronic fatigue. This can be due to excess stress of the adrenal glands, nutrient deficiencies left by a virus, and possible damage to the body's cells triggered by the inflammation from fighting the virus.

Poorly functioning adrenal glands

Your adrenal glands are two glands that sit on top of your kidneys and produce adrenaline and cortisol. Adrenaline and cortisol are the stress hormones that help you deal with stress and regulate energy levels. Learn more in 'What is cortisol'.

When the adrenal glands become tired after a period of prolonged or extreme stress, their function is compromised which leads to unbalanced and low moods, and low energy and fatigue.

Poor quality sleep

You may think you are getting enough sleep, but if your quality of sleep is poor, or you do not complete a full sleep cycle, you will feel tired and fatigued during the day. Long term sleep deprivation contributes towards a number of health conditions as well as chronic fatigue, so understanding and correcting sleep cycles is important.

Poor gut health and digestion

You may be eating a good diet, but if your gut health is compromised, you will not be absorbing as many nutrients as you should be. Low digestive enzymes and poor gut bacteria are the main causes of poor digestion. The probiotics in your gut also aid with the synthesis of serotonin, your 'happy hormone' that is needed for motivation and mental function. Discover the 6 signs of an unhealthy gut.

Low thyroid function

Your thyroid gland is located in your neck and produced thyroid hormones out of iodine. Thyroid hormones control metabolism and the rate at which you make energy. An underactive thyroid is a common cause for tiredness and fatigue.

Heavy metals

Having a store of heavy metals in your body can interfere with energy production. Heavy metals can accumulate due to many factors including smoking, using aluminium cookware, and mercury tooth fillings. Heavy metals are also included in some common pharmaceutical medications.

Why am I always tired?

Here are five ways to get to the bottom of chronic fatigue and relentless tiredness and what's causing it. 

1. Get a blood test

Ask your GP for a blood test to look for deficiencies of Iron, B Vitamins and other nutrients. Any deficiencies found can be corrected by supplements or a change in your diet. 

2. Analysis diet

Not all nutrient deficiencies can be detected by a blood test, so it is important to adapt your diet to address any obvious deficiencies, or remove foods that can contribute to fatigue.

Start by removing foods that inhibit energy and sleep, and replacing these one-by-one with foods that are beneficial for energy. Keep a log of what you remove from your diet and monitor your energy levels. Each change you make should last at least 5-10 days, so it may be 6-8 weeks before you identify what works well for you, and what doesn't.

You may need professional to help you with this if you are unsure. Taking a comprehensive Daily Multivitamin formula can also safeguard your intake of essential nutrients and protect against deficiencies.

3. Get your thyroid checked

Ask your GP for a thyroid test. There are several elements that need to be looked at in a thyroid test. These are TSH, T4, T3 and reverse T3. Until you have the results to all of these, low thyroid hormones can’t be ruled out.

4. Assess your sleep quality

Keep a track of the number of times you wake during the night and the actual hours you are asleep for. A sleep tracking device or app on a smart phone can help you do this so you understand how many hours of deep and good quality sleep you are getting, as well as picking up on any sleep apnoea, where your breathing stops and starts while you sleep.

5. Check for heavy metals

Having a small amount of heavy metals, such as Iron and Zinc, is essential for the health of our body. However, too large amounts can be toxic. A professional nutritionist or naturopath can help you access tests to look at your heavy metal status. If heavy metals in your body are too high, they can help you to detoxify. 

Best foods to beat tiredness

Sunflower & pumpkin seeds

Sunflower and pumpkin seeds contain the amino acid L-tryptophan. L-tryptophan converts in our gut into 5-HTP, and then into serotonin and melatonin. Serotonin is our 'happy hormone' and is needed for focus, concentration, a sharp mind and improving our brain's memory function. Melatonin is our sleep hormone and is required for the onset of sleep.

5-HTP can also be taken as a supplement half an hour before bed to promote better sleep and is a key ingredient in Vegan Nights, a unique formula for better, deeper sleep.
