Fluid absorption

The pig faces significant biological and environmental challenges after weaning. A great deal of information is available on behavior, environment, health, and nutrition of the newly weaned pig; however, newly weaned pigs still suffer a growth lag. The pig’s small intestinal structure and function is altered during the days that follow weaning. As a consequence, the digestive and absorptive capacity of weanling pigs is decreased during this period and this may be partially responsible for the post weaning growth lag....

A Abatement: Reducing the degree or intensity of, or eliminating, pollution. Abatement Debris: Waste from remediation activities. Absorbed Dose: In exposure assessment, the amount of a substance that penetrates an exposed organism's absorption barriers (e.g.,, skin, lung tissue, gastrointestinal tract) through physical or biological processes. The term is synonymous with internal dose. Absorption Barrier: Any of the exchange sites of the body that permit uptake of various substances at different rates (e.g., skin, lung tissue, and gastrointestinal-tract wall).

Diarrhea Enteral feeding often leads to diarrhea, especially if bowel function is compromised by disease or drugs, particularly broad-spectrum antibiotics. Diarrhea may be controlled by the use of a continuous drip, with a fiber-containing formula, or by adding an antidiarrheal agent to the formula. However, Clostridium difficile, which is a common cause of diarrhea in patients being tube fed, should be ruled out before using antidiarrheal agents. H2 blockers may also assist in reducing the net fluid presented to the colon.

Postmucosal Lymphatic Obstruction The pathophysiology of this condition, which is due to the rare congenital intestinal lymphangiectasia or to acquired lymphatic obstruction secondary to trauma, tumor, or infection, leads to the unique constellation of fat malabsorption with enteric losses of protein (often causing edema) and lymphocytopenia. Carbohydrate and amino acid absorption are preserved. INFLAMMATORY CAUSES Inflammatory diarrheas are generally accompanied by pain, fever, bleeding, or other manifestations of inflammation.
