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.

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.

A sore or hole in the lining of an organ is known as an ulcer. A stomach ulcer is known as a gastric ulcer while a duodenal ulcer is an ulcer in the duodenum which is part of the small intestine. Duodenal ulcers occur more frequently in men and usually between the ages of 20-45, while stomach ulcers occur more often than not in people over the age of 50.
The stomach is protected from acid by a lining of mucus but if the lining is damaged then the acid can come into contact with the stomach or intestine wall, causing an ulcer.
Symptoms of an ulcer include abdominal pain, feeling sick after eating, loss of appetite, weight loss, or difficulty swallowing. More serious symptoms include black or tar like stools, severe stomach pain, or vomiting blood.

Stomach Ulcers
Ulcers can be caused by bacteria known as Helicobacter Pylori and also use of non-steroidal anti-inflammatory drugs (NSAIDs) such as aspirin. Other causes of ulcers are smoking and drinking alcohol and it is also thought to run in some families. Stress can aggravate an ulcer as it causes the stomach to produce more acid.
Diagnosis of an ulcer is confirmed through a procedure known as an endoscopy. This is done in a hospital and it involves a thin tube being passed down to the stomach through the mouth and gullet. This can show the doctor whether an ulcer is present.
Treatment of an ulcer depends on whether the cause was a bacterium or by using NSAIDs. Proton pump inhibitors are prescribed for ulcers which have not been caused by the H pylori bacteria and they work by reducing the amount of acid in the stomach. For ulcers caused by H pylori bacteria, treatment is usually a combination of proton pump inhibitors and two antibiotics.
