A large bowel obstruction is a blockage of the large intestine which prevents the passage of intestinal contents. Digestive function will be extremely compromised if food, fluid and gasses cannot continue through the large intestine. Necrosis of the intestine is also likely in cases of large bowel obstruction. There are two variations in what can cause a large bowel obstruction; mechanical obstructions and foreign body obstructions. Mechanical obstructions occur as a function of the body itself.
2) Coronary artery disease is usually caused by a build-up of fatty deposits on the walls of the coronary arteries. The fatty deposits, called atheroma, are made up of cholesterol and other waste substances. The build-up of atheroma on the walls of the coronary arteries makes the arteries narrower and restricts the flow of blood to the heart. Cholesterol is a fat made by the liver from the saturated fat that we eat. Cholesterol is essential for healthy cells, but if there is too much in the blood it can lead to CAD.
Smokers’ cough turns into chronic bronchitis, caused by the deteriorated cilia. Mucus thickens and becomes greater in amount, thickening the lining of the bronchioles, resulting in difficulty breathing. The bronchioles steadily lose their elasticity which prevents them from absorbing the pressure on the alveoli, causing the alveoli to rupture; smoking-induced emphysema. This progression results in a worsening cough, wheezing, difficult breathing, and fatigue. As these structural changes are occurring, there are also cellular or molecular changes taking place in the lungs.
Kidneys: A wide range of kidney diseases can occur in Alagille syndrome. The kidneys can also have decreased function. (1,3) [pic] One of the major elements of Alagille disease is malfunctions to the liver. Liver damage can be caused by abnormalities in the bile ducts. Bile ducts carry bile from the liver to the gallbladder, and bile is what helps to digest fats.These bile ducts may be limited and tight, so the bile gets trapped and will build up inside the bile ducts which prevent the liver from working to its best ability (1,3).
Most infants with cystic fibrosis are born with Meconium Ileus. Most infants without this condition are diagnosed four to six weeks later when parents and doctors notice that the infant coughs frequently, and has not gained weight, even though it is eating enough. To test for cystic fibrosis, doctors often use a basic test called a sweat test. Cystic fibrosis has been affecting humans since the middle ages. Cystic fibrosis was unstudied until the early 1900’s.
An ischemic stroke is typically caused by excess buildup of plague on the blood vessel walls that narrows blood flow dramatically. A hemorrhagic stroke typically occurs when the blood vessel walls weaken over time, which leads to a bulge or rupture of the vessel. Aneurysm is the most common type of hemorrhagic strokes with a low survival rate. They also kill brain cells, which can never regenerate. The affect of strokes on the body can range between mild dizziness or slight numbness to impaired speech and loss of motor control.
Pain can also occur in the shoulders, arms, neck, jaw or back. It may even feel like indigestion. It may also cause shortness of breath, nausea, breaking out in cold sweat, dizziness or lightheadedness. Coronary Artery Disease is a chronic process that begins during adolescence and slowly progresses throughout life. Independent risk factors include a family history of premature Coronary Artery Disease, cigarette smoking, diabetes mellitus, hypertension, hyperlipidemia, sedentary lifestyle, high levels of certain fats in the blood, poor diet and excessive alcohol use.
These fluids collect in and around the alveoli, and the alveolar walls thicken. Both events seriously reduce gas exchange and lead to hypoxemia, interfering with oxygenation and possibly leading to death. The capillary leak spreads the infection to other areas of the lung. If the organisms move into the bloodstream sepsis occurs. (3) Etiology: Pneumonia develops when the immune system cannot combat the virulence of the invading organisms.
Without a blood supply, the affected skin becomes starved of oxygen and nutrients and begins to break down, leading to an ulcer forming. Pressure ulcers tend to affect people with health conditions that make it difficult to move, especially those confined to lying in a bed or sitting for prolonged periods of time. Conditions that affect the flow of blood through the body, such as type 2 diabetes, can also make a person more vulnerable to pressure ulcers. Learn more about the causes of pressure ulcers. Who is affected?
Depending on its cause, pleurisy may be accompanied by other symptoms, such as, shortness of breath, fever and chills, rapid shallow breathing, unexplained weight loss, sore throat followed by pain and swelling in the joints, diarrhea, erectile dysfunction, and vomiting blood. The inflammation of the pleura sometimes causes fluid to build up in the pleural cavity. This is known as pleural effusion. You may have less pain after this happens, because the fluid prevents the two layers of the pleura from rubbing together. If there is a large amount of fluid, it may prevent the lung from expanding when you breathe in.
