Lethargy is also described as an extreme lack of energy, fatigue, or tiredness. Lethargy can occur due to lack of sleep or exercise, poor diet, boredom, stress and overworking. In most cases lethargy is a normal response to any of these conditions and can be resolved with proper sleep, regular exercise, a balanced diet, and a reduction in stress factors. However, there are some cases where lethargy may be symptomatic of another more serious physical or psychological condition. Illnesses such as cancer, asthma, anemia, sleeping disorders, thyroid problems, substance abuse, and certain medications can all cause lethargy. In such situations, lethargy may also be accompanied by feelings of depression, apathy and lack of motivation. If lethargy is chronic and does not reduce or disappear with the normal self-care methods, it is indicative that there is a deeper cause to the condition that may even require medical attention.

Symptoms of Lethargy
The underlying condition or disease will determine the lethargy symptoms. Depending on the cause of lethargy, the symptoms will vary. Since lethargy is a non-specific symptom in itself, it is useful to be aware of other symptoms so that diagnosis is more accurate. Lethargy may accompany symptoms of the cardiovascular and pulmonary systems such as chest pain, rapid heartbeat, shortness of breath, cough, wheezing, and abnormal heart rate. Lethargy leads to a decrease in overall muscular strength. This in turn affects your ability to work and play. If not treated in time, lethargy could result in a complete lack of response to any physical or emotional stimuli. Lethargy may also be a symptom of Chronic Fatigue Syndrome. Lethargy occurs mainly in adults and is relatively rare in children. If a child is exhibiting any of these symptoms, it is assumed that he or she is suffering from depression or some other medical condition.

Diet for Lethargy
Experts believe that low immunity and a poor diet are the main reasons for lethargy. The foods you eat can affect your body and make a huge difference in the way you feel on a daily basis. A diet for lethargy should not include foods high in fat, sugar, or additives and chemicals. Over-processed foods should be replaced by whole foods and super foods instead. Avoid white sugar, fatty foods, oily and spicy foods that put too much stress on the digestive system. Imbalances of bacteria levels in the digestive system also affect the way food is processed in the body. There is no definite dietary cure for lethargy however, and the effectiveness of any diet plan may also depend on the underlying cause. To combat lethargy, you should eat a healthy balanced diet consisting of fresh fruit and vegetables, whole grains, sprouts, protein and complex carbohydrates. Drink at least eight to ten glasses of water a day to prevent dehydration and tiredness.

There are also specific vitamins for lethargy that could help. Anxiety and stress can cause lethargy. Chronic anxiety can lead to a depletion of adrenal in the body and can be counteracted by increasing your vitamin B and magnesium intake. Multivitamins high in chromium and magnesium help balance out blood sugar levels and prevent fatigue and mood swings. Iron is one of the most important nutrients especially for women. Low iron levels can result in exhaustion and chronic lethargy. Eating foods high in iron such as green leafy vegetables, red meat, and legumes can help significantly in such a scenario to fight off anemia and reduce the symptoms of lethargy. Too much iron however can cause pain, constipation, and flatulence so follow your doctor?s advice if you wish to try any supplements.
