Hepatitis A is an infection of the liver caused by the hepatitis A virus. The well-respected World Health Organization (WHO) estimates that almost 1.5 million new cases of hepatitis A related illnesses occur each year worldwide, with a much higher number of people than this affected without showing any symptoms. The condition is more prevalent in the developing world where poverty and sanitation issues are rampant.
Hepatitis A is regarded as an acute infection as opposed to a chronic one, but in rare occurrences it can cause liver damage that is life threatening. The severity of symptoms in patients with the virus varies from individual to individual and whereas some may have no symptoms at all, others may develop symptoms to those similar of catching flu. As a rule, the older a person is, the more severe the infection, and therefore the symptoms, will be.
Some of the symptoms associated with hepatitis A include tiredness, weakness, fever, headache, nausea, loss of appetite, vomiting, dehydration and diarrhea. After a week or so of these symptoms, jaundice will appear. This occurs because in hepatitis infections, the liver is unable to remove a substance known as bilirubin from the blood. The skin and whites of the eyes become a yellow color because of the buildup of this pigment.
Hepatitis can be avoided be taking the following precautions: high levels of personal hygiene, drinking safe tap water and getting vaccinated against the disease if a visit to a high risk country is to be taken.

Nearly everybody alive goes through a state of feeling sad, or what we normally call depressed, but this usually goes away after a time. Individuals that happen to have a depressive disorder, or what we know as clinical depression, tend to find that this interferes with their daily lives and routines.

Depression in Men
To give depression an official description, the MediLexicon’s Medical Dictionary states that: depression is “a mental state or chronic mental disorder characterized by feelings of sadness, loneliness, despair, low self-esteem, and self-reproach; accompanying signs include psychomotor retardation (or less frequently agitation), withdrawal from social contact, and vegetative states such as loss of appetite and insomnia.”

Depression in Women
There are many types of depressive disorders and these include dysthymic disorder, major depressive disorder, psychotic depression, postpartum depression (which is normally referred to as postnatal depression), SAD (seasonal affective disorder) and bipolar disorder.
The symptoms and signs of depression are not clear-cut at all. Some symptoms that may be experienced by some individuals may not be had by others. Also, the severity of the illness all depends on the individual concerned and the type of depression they may have. Nevertheless, common symptoms experienced by sufferers of depression include the feeling of pessimism, sadness or anxiety; feelings of hopelessness, restlessness and irritability; loss of interest in pursuits, activities and sex, among other things; fatigue, loss of concentration and disturbed sleep; aches and pains, change of eating habits and sometimes even suicidal thoughts.

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.
