An anxiety disorder can loosely be described as a condition where feelings of anxiety can get in the way of normal, everyday life. Many things can cause or even be classed as an anxiety disorder, and these can include phobia, obsessive compulsive disorder (OCD), post traumatic stress disorder (PTSD), panic attacks and generalized anxiety disorder (GAD).

Anxiety attacks can be caused by a variety of conditions, both mental and physical. On the mental side of things, problems such as alcohol dependence, depression, substance abuse (including drugs, nicotine and caffeine) and medicine withdrawal can all cause anxiety. Physically, a person could be affected due to illnesses or cosmetic reasons such as appearance. It can also be brought on by stress due to traumatic events like bereavement.

Anxiety

There are some physical symptoms attributed to being anxious and these occur due to the body’s natural “fight or flight” response due to the release of adrenaline. These can include dry mouth, diarrhoea, tightness in the chest, rapid heartbeat, dizziness, shortness of breath, shaking, the need to urinate more frequently and swallowing difficulty.

A few psychological symptoms associated with anxiety include uneasiness, insomnia, irritability, tiredness, lack of concentration and a fear of “going mad”. Sometimes, when anxiety disorders and other conditions such as schizophrenia, depression or bipolar disorder occur together, suicide or self-harm can often be the regrettable outcome.

Tuberculosis is a condition which primarily affects the lungs.  The bacteria which cause tuberculosis are slow moving bacteria and a person who has been infected might not have any symptoms for months or years afterwards.  The infection can spread to other parts of the body such as the nervous system or the bones.  Symptoms of tuberculosis include a cough that won’t go away, night sweats and weight loss but most of the time the immune system will kill off the bacteria and there will be no symptoms.  Sometimes, if the immune system cannot kill the bacteria it will build up a defense to the infection and it will stay in the body but no symptoms will be experienced, however, sometimes the body just cannot fight the bacteria and the infection spreads to the lungs and becomes known as active tuberculosis.  It can happen that in cases where the infection has lain dormant in the body in can become active at a later date.

Tuberculosis

Tuberculosis was a major disease many years ago and resulted in many deaths, but the introduction of antibiotics and vaccinations helped to reduce this.  In recent years though, tuberculosis cases have been increasing again, especially in ethnic minorities who have come from areas where tuberculosis is still widespread. Areas where the disease is widespread include countries of Africa south of the Sahara desert, Eastern Europe, Central America, South East Asia, and Russia.

If tuberculosis is not treated it can be deadly as it can result in the person not being able to breath properly. Treatment with antibiotics for tuberculosis usually involves taking a course for at least six months.

The heart is a pump that is designed to force blood through the body and as with any type of pump, it works by generating pressure. In the body, the blood is pumped through the arteries to all major organs, but if there is too much pressure it can put a strain on the heart itself or the arteries, causing all sorts of problems.

Blood pressure is dependent on two things. The first is the force with which the heart pumps the blood around the body, and the second is the narrowness of the arteries. Hypertension happens when the blood is forced with increased pressure through the arteries.

When blood pressure is measured, it is done so using two numbers, an example being 120 over eighty. The first number listed is the systolic blood pressure which is the maximum pressure exerted on the arteries when the heart beats, and the second number listed is the diastolic blood pressure, or the minimum amount of pressure on the arteries when the heart is relaxed. The example above is of a normal blood pressure reading.

Blood pressure can be considered high when the systolic blood pressure reading is constantly above 160, and/or the diastolic blood pressure reading is above 100. One of the biggest problems with high blood pressure though, is the fact that it doesn’t always cause any symptoms meaning it may go unnoticed until a later complication such as a heart attack or stroke.

Other complications arising from high blood pressure can be an aneurysm, heart failure, eye damage, kidney failure or atherosclerosis, which is the narrowing of the arteries. Some factors that could contribute to high blood pressure include hereditary reasons, obesity, kidney disease, diabetes, excessive salt intake, lack of exercise and high intake of alcohol.
