Chronic tiredness and fatigue can have a major impact on your life, making it difficult to perform daily tasks. Work, social life and family relationships can all suffer when you’re feeling too tired to participate fully. Finding the cause of chronic tiredness is the key to beating fatigue. Here are five common causes of fatigue.


Being overweight puts a strain on your heart, limbs and general health, making it more difficult to maintain stable energy levels. Carrying extra weight also puts you at risk of insulin resistance, which can cause an imbalance of blood glucose levels, leaving you feeling tired, weak and irritable. Being underweight can also have a negative impact on your energy levels.

Weight Loss Programs

Diets and weight loss programs that rely on calorie restriction or avoiding major food groups, such as carbohydrates or fats, can also cause fatigue, as well as nutritional deficiencies. Eating a balanced diet is crucial for maintaining physical and mental health, so it’s important to seek advice from a doctor or nutritional therapist before starting a restrictive diet plan.

Digestive Problems

Digestive problems and diseases, including irritable bowel syndrome (IBS), leaky gut syndrome and reflux disease, can all affect your energy levels. In addition, digestive problems and diseases of the gut can make it more difficult for your body to absorb nutrients from your food, increasing the risk of nutritional deficiencies.


Stress takes its toll on your body, leading to fatigue, lethargy, unexplained pain and a general sense of being unwell. Stress also robs your body of vital vitamins and minerals, leading to nutritional deficiencies that can affect your energy levels, stamina and cognitive abilities. Chronic stress that lasts for several weeks or months can even lead to serious disease, including hypertension and heart disease, so it’s important to address the cause of long-term stress as quickly as possible.


Eating a diet high in processed food, refined carbohydrates and sugar can cause wild fluctuations in blood glucose levels, causing sudden tiredness, weakness and irritability. It can also lead to food cravings and nutritional deficiencies that make the problem worse. Increasing your intake of whole grains, high-quality protein, fruit and vegetables can make a huge difference to your physical and mental health.

Fatigue is a common problem that affects people of all ages. Weight, weight loss programs, digestive problems, stress and diet can all cause or make fatigue worse. However, it’s important to talk to your doctor if fatigue is affecting your daily routine, as it could be a sign of health problems that require medical treatment.
