Chronic fatigue syndrome (CFS) is usually characterized by a prolonged bout of fatigue accompanied by a wide range of other symptoms. The condition can affect individuals of any age but is more common between the ages of 25 and 45, with females usually affected more than males.

An adult is diagnosed with CFS if, for at least four months, they have had chronic fatigue but with no obvious other medical issue causing the condition. The main symptoms associated with CFS include sore throat, muscle pain, lack of concentration, joint pain, headaches, and fitful sleep. Some other symptoms that can also occur are abdominal pain, bloating, cough, chest pain, earache, jaw pain, stiffness, diarrhea, weight loss, nausea and night sweats.

As a rule, the symptoms of CFS are not improved by taking bed rest and conversely may be made worse by some physical or mental activities. As it is unknown what actually causes the condition, it is very difficult to prevent; it is not, though, a contagious condition. Some causes that are thought to contribute to CFS include having had a viral infection of some description, depression, stress or a life changing event such as loss of employment or bereavement.

The prevalence of fatigue states

Following on from this, there are no specific treatments’ for the condition either, but medication can be prescribed for the associated symptoms, for example, taking painkillers for headaches.

A headache involves having mild to severe pain in a specific, or many, areas of the head or back of the neck. Countless “types” of headache exist, all caused by a variety of reasons, and although they can be painful and rather annoying, they are, for the most part, not a sign of a serious disorder and in most non-chronic situations can be treated and relieved by medicines.

Although there is no single cause of a headache, several causes have so far been identified by the medical community and these can fall into two main categories – tension headaches and migraine headaches. Tension headaches are the result of contraction of the neck and head muscles and are the most common type of headache, accounting for nearly seventy percent of cases. Some causes of muscle contraction linked with tension headaches include stress, fatigue, eye strain, poor posture, hormonal changes, and alcohol or tobacco use.

Migraine headaches occur when blood vessels located in the neck and head constrict, which therefore leads to decreased blood flow in them. Symptoms of migraine include a throbbing pain usually on one particular side of the head, along with a feeling of nausea and sensitivity to sound or light. Migraines are usually chronic and affect more women than men

Headache

Although for the most part headaches are not a sign of anything sinister, as mentioned above, there are certain symptoms that need to be looked at by a doctor or physician immediately. These include a sudden onset of headache accompanied by vomiting or nausea; recurring headaches which are accompanied by memory issues, tiredness and difficulty in concentrating; neck stiffness accompanied by high fever; fits; vision irregularities, i.e. light flashes; trouble controlling, or loss of feeling in, the limbs; and difficulty in communicating while being tired and apathetic.

HIV, or human immunodeficiency virus, is the virus which can lead to AIDS. There are many ways to contract this virus, with the most common being through unprotected sex and the sharing of needles.

People who are infected with HIV may initially not realize there is anything wrong with them as they do not show any symptoms. Nevertheless, some people tend to develop some flu like symptoms which can last for several weeks. Some of these symptoms may include fever, tiredness, loss of appetite, aching muscles and joints, rashes and swollen lymph glands.

HIV Virus Structure

When the virus enters the body, it takes residence in white blood cells that are known as CD4 lymphocytes. The virus takes total control of these cells and starts producing billions of replicas of itself every day.

Once infection of HIV occurs, the body starts to attack the virus and because of this the virus cannot make any copies of itself. This in turn leads to a false sense of wellness as although one would still have HIV, the infected person will begin to look and feel better. Unfortunately, during this period the virus is still attacking the lymph nodes, which are the body’s immune system center.

During the course of ten to fifteen years, the HIV manages to kill so many of the CD4 cells that the body no longer has the ability to fight off infections. Once the CD4 cell count drops below a certain number (200 or lower per mL – the average is 600 to 1000) the sufferer is classed as having AIDS (acquired immunodeficiency syndrome). Once a person has AIDS, the risk of infection form almost anything can cause fatal complications.
