Organ failure often leads to death. A person's organs may shut down due to nutritional or circulatory insufficiency, overwhelming infection, prolonged sickness or overuse. Acute organ failure from Multiple Organ Dysfunction Syndrome differs in duration and causation from long term organ failure such as congestive heart failure, according to ModernMedicine.Know More
In cases of congestive heart failure the heart's function decreases over time, leading to systemic body dysfunction. According to eMedicineHealth, heart failure is simply a term used when body tissues are not receiving as much blood and oxygen as they require. This may be a temporary condition and does not mean that the heart stops working altogether as it does in fatal myocardial infarction. When the pumping action of the heart is decreased, it causes blood to back up, increasing pressure in the blood vessels and forcing fluid into body tissues. Fluid build-up is evidenced by edema and ascites.
Acute organ failure may be caused by Multiple Organ Dysfunction Syndrome, or MODS. Medscape defines MODS as a process in which there is a "progressive physiologic failure of several interdependent organ systems." Initial infection can worsen to become systemic, eventually leading to MODS. Many organ systems can be affected by MODS, leading to circulatory derangement as well as dysfunction of the pulmonary system, gastrointestinal system, liver, kidneys, and central nervous system. When these systems fail to function, the patient will not survive.Learn more about Organs
WebMD states that injecting too much insulin usually leads to low blood sugar levels, or hypoglycemia. Symptoms of hypoglycemia include confusion, intense anxiety, shakiness, sweating or clammy skin, irritability, fatigue and extreme hunger. If blood sugar levels fall too low, serious complications are possible, including seizures and unconsciousness.Full Answer >
According to WebMD a pancreas that has ceased to function properly will result in a swollen abdomen, severe abdominal pain, fever, increased heart rate, weight loss, nausea and the onset of diabetes. The pancreas is crucial to proper digestion and metabolism of nutrients, and a non-functional pancreas can put a person's life at risk.Full Answer >
Dead brain cells, or neurons, are eliminated through phagocytosis, a process performed by scavenger cells in the body called phagocytes, states Medical News Today. During neurogenesis (birth of neurons), thousands of brain cells are produced, yet only a small fraction of them survive as the rest die.Full Answer >
A mixture of food, liquid and digestive juice called chyme enters the small intestine from the stomach and combines with secretions such as enzymes, bicarbonate and bile salts to further break down food, according to the International Foundation for Functional Gastrointestinal Disorders. These enzymes come from the liver and pancreas. Food digests in three distinct parts of the small intestine.Full Answer >
