Influenza can be defined as a viral disease that once contracted can last from between three to five days. Influenza is normally accompanied by aching joints and muscles, cough, headaches and fever, and sufferers normally go through a period of two to three weeks feeling fatigued. The disease can become serious, leading to such conditions as pneumonia, brain and nerve damage and sometimes even death, but occurrences of these serious conditions are rare.

Other symptoms can occur with influenza and these can include chest pain, loss of appetite, restless sleep, chills, indigestion, and vomiting. Individuals that catch influenza should drink as much fluid as they can due to the fever, rest while trying to get lots of sleep, and avoid smoking or drinking alcohol. A person should contact their doctor should the symptoms still be present after a week, or if they are feeling worse than they were.

Influenza

Influenza is spread from individual to individual through the air, infecting the throat, nose or lungs once contracted. As it can spread very quickly, epidemics often occur with affected areas in the grip of the virus from four to six weeks.

The elderly are particularly at risk from the disease, while individuals with lung or heart disease can develop complications if struck by flu. The people who are most at risk are advised to seek yearly vaccinations.

Individuals who suffer from recurring panic attacks suffer from a condition called panic disorder. This condition can very often lead to agoraphobia (fear of open or public places). Having a panic attack means suffering an attack of fear or anxiety which comes on very suddenly for no apparent reason. As well as anxiety, panic attacks can be accompanied by the following symptoms: thumping heart or palpitations; sweating; chills or hot flashes; shortness of breath; feeling sick; chest pains; dizziness or feeling faint; fear of dying; fear of going mad; pins and needles or numbness; and, feelings of detachment.

Any physical symptoms associated with an attack do not indicate a physical problem with the chest, heart, abdomen, etc – they usually occur due to a rush of nervous impulses originating in the brain which go to various parts of the body during the attack.

It is known that at the very least, one in ten people have had an occasional panic attack, but to have a panic disorder means to have recurring panic attacks, the frequency of which varies in different people.

No treatments are usually necessary for the occasional panic attack, but for those who have a panic disorder the aim is to try and reduce the severity as well as number of panic attacks that occur and the main types of medication for these are antidepressants.

Panic Disorder

When the heart is unable to pump blood around the body efficiently, it is known as heart failure. Heart failure can affect either the left or right side of the heart, or in some cases, both sides. The condition can be brought on by a number of diseases including high blood pressure, heart valve disease, blood clot in the coronary arteries and heart muscle disease.

Symptoms include shortness of breath, breathing problems, coughing, fatigue, leg swelling, eczema type rash and accumulation of fluid in the organs or abdominal cavity. Heart failure is usually diagnosed by a combination of medical history along with an examination that will check out such issues as heart sounds, heart rate, heart murmurs, fluid on the lungs, swollen legs, swollen neck veins or an enlarged liver. It can also be diagnosed by means of a chest x-ray, an ECG and blood samples. Doctors can also find out what caused the heart failure by performing additional blood tests so certain viral infections can be spotted, an ultrasound of the heart, a coronary artery examinations (done by injecting a dye into the left and right coronary arteries), exercise testing carried out on a treadmill and by taking a biopsy of a small bit of heart muscle.

Heart Failure

Ways to avoid heart failure include stopping smoking, a change of diet as well as avoiding overeating, exercising more often and getting problems such as high blood pressure or high cholesterol treated in a timely manner.
