Coronary heart disease is usually caused by a condition called atherosclerosis, which occurs when fatty material and a substance called plaque builds up on the walls of the arteries. Diabetes, high blood pressure, menopause, not getting enough physical activity, obesity and smoking increase risk.

The bacterium that causes Johne's disease is named Mycobacterium paratuberculosis often the name is abbreviated M. paratuberculosis. M. paratuberculosis is a relative of the bacterium that causes tuberculosis in humans (Mycobacterium tuberculosis), cattle (Mycobacterium bovis), and birds (Mycobacterium avium - Some taxonomists favor the name Mycobacterium avium subspecies paratuberculosis for the organism that causes Johne's disease, since genetically it is closely related to M. avium. M.

M. paratuberculosis infects the last part of the small intestine (called the ileum) and causes a certain kind of inflammation called granulomatous inflammation. This inflammation thickens the intestinal wall, preventing it from functioning normally. This, among other factors, causes diarrhea and poor absorption of nutrients. As a result, even though animals will seem to be feeling and eating well, they will rapidly lose weight.

There are several reasons why patients develop serious gum disease. Although there may be some hereditary influence, the majority of gum problems result from controllable factors. Patients who have neglected regular home care like brushing and flossing, or who have failed to visit a dentist for professional cleaning, tartar removal and oral evaluation often develop signs of gum disease.

Unfortunately, the causes of inflammatory bowel disease are not well understood. Usually, a cause is not found. The basic theory is that "something" is leading to a chronic stimulus of inflammation. This could be an allergy against a food protein, the continuing presence of a parasite, inflammatory products produced by the normal bacteria living in the intestine or there may be an underlying problem with the immune system in affected individuals.

Diabetes is the number one cause of kidney disease, responsible for about 40% of all kidney failure. High blood pressure is the number two cause, responsible for about 25%. Another form of kidney disease is glomerulonephritis, a general term for many types of kidney inflammation. Genetic diseases, autoimmune diseases, birth defects, and other problems can also cause kidney disease.

Chronic kidney disease is caused by damage to the kidneys. By far the most common causes of this damage are: Kidney diseases and infections, such as polycystic kidney disease, pyelonephritis, and glomerulonephritis, or a kidney problem you were born with. Long-term use of medicines that can damage the kidneys. Examples include pain medicines, like acetaminophen (such as Tylenol) and ibuprofen (such as Advil), and certain antibiotics.

Research to date has not been able to identify the exact cause of this condition. There is evidence to suggest that some people may have a genetic predisposition to Parkinson's, but there is no clear evidence to suggest that it is hereditary. Other risk factors that have been identified are head injury, direct occupational pesticide exposure and the age-related loss of brain cells that transmit nerve impulses. Despite popular belief, Parkinson's is not found only in the elderly.

Doctors don't know what causes Crohn's disease. You may get it when the body's immune system has an abnormal response to normal bacteria in your intestine. Other kinds of bacteria and viruses may also play a role in causing the disease. Crohn's disease can run in families. Your chances of getting it are higher if a close family member has it. People of Eastern European (Ashkenazi) Jewish family background may have a higher chance of getting Crohn's disease.

When it comes to Crohns Disease, at this time there are no proven direct causes. Theories include family history or genealogy, the immune system, and environmental and/or a complex combination of them. Patients with the disease generally exhibit immune system anomalies; however the difficulty in diagnosis posed becomes; are the anomalies the cause or the effect.

This is the question most often asked, but unfortunately the answer is still not known. It is likely that several factors work together. There may be an inherited predisposition that places an individual at higher risk of developing IBD. Research among families with more than one affected member will be important in discovering what accounts for this predisposition. Some trigger in the environment sets up the inflammation, and in the predisposed individual this does not go away.

There are many known causes of lung disease. Still, the causes of many lung diseases are still not known. Some known causes of lung disease include: Smoking. Smoke from cigarettes, cigars and pipes is the number one cause of lung disease. So the best thing you can do to reduce your risk of lung disease is to stop smoking. If you live or work with a smoker, it is also very important to steer clear of second hand smoke. Ask the person to smoke outdoors. Radon gas.

My personal research and experience shows certain life situations and conditions can trigger the onset of this disease. In general this is stress, improper diet, major stress situations or a combination of these factors. In most of the cases your eyes will recover, once your tests become normal and your symptoms are under control. However there are certain methods like eye exercises, cold compress, flax seed oil, lubricating drops etc that can improve your condition and relief your pain.

Diabetes is the leading cause of chronic kidney failure; diabetes accounts for approximately one third of new cases of chronic kidney failure in the United States each year. Uncontrolled or poorly controlled high blood pressure is the second leading cause of chronic kidney failure in the United States; it accounts for about 30 percent of all cases.

No one knows for sure what causes IBD. But, researchers think the following things may all play a role: Many researchers think that abnormal action of a person's immune system may trigger IBD. Normally, the immune system protects the body from infections caused by viruses or bacteria. Once the infection has cleared up, the immune system "shuts off." But in people with IBD, the immune system seems to overreact to something in the digestive tract.

Newcastle Disease is caused by a Paramyxovirus. It is very resistant and survives a pH of 2 to 12, heating to 130° F (56° C) for 3 hours, and can survive freezing indefinitely. Extended drying and ultraviolet light will kill the virus. END virus can survive for several weeks in the warmth and humid environment of a poultry production unit on feathers, in manure, and other materials.

In normal digestion, the lower esophageal sphincter (LES) opens to allow food to pass into the stomach and closes to prevent food and acidic stomach juices from flowing back into the esophagus. Gastroesophageal reflux occurs when the LES is weak or relaxes inappropriately, allowing the stomach's contents to flow up into the esophagus. The severity of GERD depends on LES dysfunction, as well as the type and amount of fluid brought up from the stomach and the neutralizing effect of saliva.

Although there are many theories about the cause of Parkinson's disease, none has ever been proved. Recent studies of twins and families with Parkinson's have suggested that some people have an inherited susceptibility to the disease that may be influenced by environmental factors. The strong familial inheritance of the chromosome 4 gene is the first evidence that a gene alteration alone may lead to Parkinson's disease in some people.

The agent that causes CWD and other TSEs has not been completely characterized. However, the theory supported by most scientists is that TSE diseases are caused by little understood proteins called prions. Prions are a form of protein normally found in the cells of the nervous system and other body tissues. Stanley Prusiner, a Nobel Prize winning neurologist, first described an abnormal form of prion resistant to enzymes that break down normal proteins.

The first case of BSE, or Mad Cow Disease was discovered on 12/23/03 in the US. The purpose of this FAQ is to educate about the disease causative agent, how the disease is transmitted, and potential human concerns. For in-depth human health and current political issues concerning BSE, please visit with your local health care provider or refer to local/national/Internet news sources.

What are my chances for going back to work after a wrist fracture? I think I broke just the end of the radial bone but it moved to one side, so I had to have surgery to put it back in place. What in the world is a "Jersey finger"? Our son is a football player away from home for the first time. He emailed us to tell us he has a Jersey finger and not to worry.

Coronary artery disease is caused by hardening of the arteries, or atherosclerosis. Atherosclerosis occurs when plaque builds up inside the arteries. (Arteries are the blood vessels that carry oxygen-rich blood throughout your body.) Atherosclerosis can affect any arteries in the body. When it occurs in the arteries that supply blood to the heart, it is called coronary artery disease. Plaque is a fatty material made up of cholesterol, calcium, and other substances in the blood.

At this time, we do not yet know the cause(s) of classic (idiopathic) Parkinson's disease. Many different theories have been and continue to be under investigation in an effort to pinpoint the factor/factors that need to be involved for this disease to develop.

Atherosclerosis is the most common cause of carotid artery disease. It is unknown exactly how atherosclerosis begins or what causes it. Atherosclerosis is a slow, progressive, vascular disease that may start as early as childhood. However, the disease has the potential to progress rapidly. It is generally characterized by the accumulation of fatty deposits along the innermost layer of the arteries. If the disease process progresses, plaque formation may take place.
