Cholesterol is a lipid, or fat, of the body, and it is this along with another lipid called triglyceride that are vital building blocks of a cell. They are also used in the production of hormones as well as producing energy. Cholesterol is mainly produced in the liver, but it can also be ingested with certain foods.

There are two types of cholesterol and just to keep things simple, these can be classed as the good sort (high-density lipoprotein or HDL) and the bad sort (low-density lipoprotein or LDL). The HDL is effective in reducing cholesterol by transporting it back to the liver from where it is eliminated, whereas the LDL can contribute to certain diseases associated with the heart or blood circulation. HDL levels can be raised through exercise and LDL lowered by eating less saturated fat or sometimes with the aid of medication.

Cholesterol levels can be hereditary as well as being influenced by which part of the world the sufferer lives in. Northern Europeans have higher levels than their Southern counterparts, for example, and a much higher level than Asian people.

High Cholesterol

There are no symptoms of having high cholesterol and it is only one factor of many that can contribute to hardening of the arteries. Other factors include smoking, diet, alcohol intake, exercise and body weight. If going on a cholesterol lowering diet doesn’t help to reduce the levels, then medication will be required to assist the process.

Sciatica refers to any pain or compression of the sciatic nerve.  The sciatic nerve runs from the back of the pelvis and right down through the buttocks and both legs and ends at the feet. If something presses on the sciatic nerve it can cause a pain that runs from the lower back and down the leg; this pain can be mild to severe.

Sciatica

Causes of sciatica include slipped discs which can get temporarily moved out of place and then press on the sciatic nerve.  Acute sciatica is pain which lasts up to six weeks whereas chronic sciatica lasts longer than six weeks. Most cases clear up unaided but using painkillers, hot or cold compresses and exercise can help to alleviate symptoms. Sometimes there is a need to contact a physiotherapist especially for chronic sufferers.

Sciatic pain is different to back pain in that it also affects the legs.  Sciatica can cause weakness in the legs or feet. There is a rare condition which can cause sciatica and this is called Cauda Equine Syndrome.  This can lead to paralysis if left untreated as it can permanently damage the nervous system.  A sign of cauda equine syndrome is the sudden loss of bladder or bowel control and if this occurs immediate medical help should be sought.

Another cause of sciatica has been put down to general wear and tear.  This is why people over forty with jobs involving a physical activity are more prone to sciatica.

People with personality disorders may have conditions such as not being able to live with others, not being able to maintain relationships with other people, finding it difficult to control emotions or upsetting other people when distressed.

Causes of personality disorders can include genetic makeup, mental or emotional state or brain problems. There are three types of personality disorder: suspicious, emotional and impulsive, and anxious.

Suspicious personality disorders are where the sufferer is often paranoid of other people, and finds it difficult to interact with others, preferring their own company instead.  The person with a suspicious personality disorder is often seen by others as strange or peculiar.

Emotional and impulsive personality disorders are where the sufferer is indifferent to other people’s feelings and can be quite aggressive.  They often find it difficult to control emotions and will do this spontaneously without thinking about the consequences.  Sufferers will also self harm if they feel really bad about themselves.

Anxious personality disorders are where the sufferer worries about everything.  They are very indecisive and worry constantly about doing the wrong thing.  Anxious sufferers are overly sensitive to criticism and can often feel worthless or incompetent.

There are therapies which can help such as psychotherapy or cognitive behavioral therapy.  There is also medication available to help with the different groups of personality disorders.  Antipsychotic drugs can help those in the suspicious group while antidepressants can help to relieve the symptoms of those in the emotional group.  There are also some antidepressants which have been shown to help those in the anxious group such as serotonin reuptake inhibitors (SSRI).
