This problem can be caused by several reasons. Some of them are:
Chronic Fatigue Syndrome : (Chronic fatigue syndrome (CFS), also known as myalgic encephalomyelitis (ME), post-viral fatigue syndrome (PVFS), and various other names, is a syndrome (or group of syndromes) of unknown and possibly multiple etiologies, affecting the central nervous system (CNS), immune, and many other systems and organs. There is no simple diagnostic test; CFS is a diagnosis of exclusion, although recent research indicates biological hallmarks of the syndrome, and a diagnostic test is predicted soon. Most definitions (other than the 1991 UK Oxford criteria) require a number of features, the most common being severe mental and physical exhaustion or depletion which is "unrelieved by rest" (according to the 1994 Fukuda definition), and is often worsened by even trivial exertion (controversially, the Oxford and Fukuda criteria require this to be optional only). CFS occurs more often, but not exclusively, in women, possibly due to immunological factors (women are overall more susceptible to similar disorders). CFS is most easily diagnosed when formerly active adults become ill, but it has been reported in persons of all ages, including young children and particularly teenagers.
Patients with this diagnosis commonly report many other symptoms which are far more wide-ranging than these research diagnostic criteria, including: pain, muscle weakness, loss of brain function, hypersensitivity, orthostatic intolerance, digestive disturbances, depression, immune system weakness, and cardiac and respiratory problems. These symptoms, like the syndrome's hallmark 'fatigue', range from mild to life-threateningly severe. Some cases resolve or improve over time, and where available, treatments bring a degree of improvement to many others. Most diagnostic criteria insist that the symptoms must be present for at least six months, and all insist on there being no other cause for the fatigue: i.e. the fatigue must be idiopathic, not caused by conditions such as radiation treatment for cancer, or diabetes. CFS remains a controversial diagnosis, and even its terminology and classification are controversial).
Clinical Depression : (Clinical depression is a state of sadness, melancholia or despair that has advanced to the point of being disruptive to an individual's social functioning and/or activities of daily living. Although a low mood or state of dejection that does not affect functioning is often referred to as depression, clinical depression is a medical diagnosis and is different from the everyday meaning of "being depressed").
Sleep Disorders or Insomnia : (Insomnia is characterized by an inability to sleep and/or to be incapable of remaining asleep for a reasonable period. Insomniacs typically complain of being unable to close their eyes or "rest their mind" for more than a few minutes at a time. Both organic and nonorganic insomnia constitute a sleep disorder. It is often caused by fear, stress, anxiety, medications, herbs or caffeine. An overactive mind or physical pain may also be causes. Finding the underlying cause of insomnia is usually necessary to cure it.
Malnutrition or Vitamin Deficiency : (Malnutrition is a general term for the medical condition caused by an improper or insufficient diet. It most often refers to undernutrition resulting from inadequate consumption, poor absorption, or excessive loss of nutrients, but the term can also encompass overnutrition, resulting from overeating or excessive intake of specific nutrients. An individual will experience malnutrition if the appropriate amount, kind or quality of nutrients comprising a healthy diet are not consumed for an extended period of time. An extended period of malnutrition can result in starvation.
Malnutrition as the lack of sufficient nutrients to maintain healthy bodily functions is typically associated with extreme poverty in economically developing countries, while malnutrition as the result of inappropriate dieting, overeating or the absence of a "balanced diet" is often observed in economically developed countries (eg. as indicated by increasing levels of obesity).
Most commonly, malnourished people either do not have enough calories in their diet, or are eating a diet that lacks protein, vitamins, or trace minerals. Medical problems arising from malnutrition are commonly referred to as deficiency diseases. Scurvy is a well-known and now rare form of malnutrition, in which the victim lacks vitamin C.
Common forms of malnutrition include protein-energy malnutrition (PEM) and micronutrient malnutrition. PEM refers to inadequate availability or absorption of energy and proteins in the body. Micronutrient malnutrition refers to inadequate availability of some essential nutrients such as vitamins and trace elements that are required by the body in small quantities. Micronutrient deficiencies lead to a variety of diseases and impair normal functioning of the body. Deficiency in micronutrients such as Vitamin A reduces the capacity of the body to resist diseases. Deficiency in iron, iodine and vitamin A is widely prevalent and represent a major public health challenge. An array of afflictions ranging from stunted growth, reduced intelligence and various cognitive abilities, reduced sociability, reduced leadership and assertiveness, reduced activity and energy, reduced muscle growth and strength, and poorer health overall are directly implicated to nutrient deficiencies. Also, another, although rare, effect of malnutrition is black spots appearing on the skin.
Hunger is the normal psychological response brought on by the physiological condition of needing food. Hunger is often used as a metonym for general undernourishment.)
Other physiological conditions :
You have to consult a physician and do all necessary medical or physical checkups. If the physician do not find any physiological causes you may consult a Clinical Psychiatrist / Psychologist.
