The causes of CFS are not yet understood well. Those who develop the condition often have a recent history of viral infection, usually an Upper Respiratory Tract Infection
- such as a Cold or Flu - or a digestive tract problem that includes Diarrhoea and Vomiting. Instead of making a steady and complete recovery, the patient develops a long lasting feeling of tiredness. Most of the times this feeling can be associated with other symptoms like low-grade fever, which subsides gradually.
Once the patient feels this tiredness it takes little longer time to get back to his/her normal necessary muscular power. In other words we can say that the recovery of muscle power is very slow. So, a moderate amount of exercise that a reasonably fit, healthy person can do will help recover earlier. Any activity involving hard work by the patient is likely to take a two- or three-week recovery period to help recover the patient. Any more exertion during that time will delay the recovery still further.
There can be many causes of Chronic Fatigue Syndrome. Malfunctions of the immune system or metabolism especially in muscles are sometimes detected in CFS patients. In addition to this other factors are believed to be contributory. These factors are lack of rest, Mineral and Vitamin deficiencies, Dysfunctional Hormone production particularly involving the Adrenal and Pituitary Glands. Diet poor in nutrition or quantity, Crash Dieting.
The presence of Candida Albicans (a fungus which causes ulcers in mouth), Carbon Monoxide poisoning caused by faulty gas appliances, Environmental pollution and Chronic Intestinal Parasitic infection. The over-dose or long term intake of Antibiotics can weaken the Immune System, as can immunization. Recently changes in MRI scans have been found in some patients.
STRESS:
Stress is a significant factor affecting approximately 75 percent of patients. It works as a catalyst in the final stages of development and identification of the condition. CFS is more likely to afflict those people who drive themselves for going to workplace and in life also. Medical researches suggest that this attitude to work, among other things, inhibits the production of T-cell lymphocytes by the immune system. These cells are extremely important for defending body against attacks of microbes like viruses.
