Full Answer

CFS or myalgic encephalopathy is a medical condition that results in continual fatigue for more than six months. As a result, it becomes difficult to do daily tasks over a long period of time. The condition can be improved by lifestyle changes such as incorporating exercises and practicing better sleep routines, notes WebMD.

Hypothyroidism leads to the metabolism slowing and poor energy levels. In time, lethargy settles in, and the body adds more fat. An underactive thyroid is more common in women and can be diagnosed with blood tests. The condition can be treated by administering synthetic hormones, according to WebMD.

Intolerance to certain foods can cause fatigue. Gluten intolerance or celiac disease induces sluggishness as a result of the consumption of gluten-rich foods such as bread or cereal. Blood tests and biopsies can reveal gluten intolerance, and the diet can be altered accordingly, states WebMD.

Lifestyle factors such as excessive alcohol or caffeine consumption and frequent usage of antihistamines and cold remedies can trigger fatigue. Anxiety, depression and stress are some fatigue-causing mental health ailments. Obesity, restless legs syndrome, cancer and anemia are a few other conditions that can cause fatigue, notes Mayo Clinic.
