Laxatives and diarrhea, which speed up the passage of substances through the digestive tract,
may reduce drug absorption
. Surgical removal of parts of the digestive tract (such as the stomach or colon) may also affect drug absorption.
Does diarrhea affect food absorption?
Diarrhea contributes to malnutrition through reduction in food intake,
decrease in absorption of nutrients
, and increase in catabolism of nutrient reserves.
What happens to food when you have diarrhea?
Food is then broken down
, and nutrients are absorbed along with most of the fluid. The remaining waste and some water pass into the colon (large intestine), where more water is absorbed. And finally, the waste is passed in the form of stools to complete a digestive system function.
What affects the absorption of a drug?
Drug absorption depends on
the lipid solubility of the drug, its formulation and the route of administration
. A drug needs to be lipid soluble to penetrate membranes unless there is an active transport system or it is so small that it can pass through the aqueous channels in the membrane.
Which of the following causes of diarrhea can lead to a reduced stool pH?
Increased osmolarity causes fluid from systemic circulation to enter the intestinal lumen, resulting in diarrhea. Organic acids stimulate motility and may directly injure the intestinal mucosa.
Fermentation
eliminates the reducing substances and lowers the pH of the stool.

What factors can affect absorption of a drug when it is taken orally?
When a drug is taken orally, it must be
able to survive the low pH and presence of potentially degrading enzymes in the gastrointestinal tract
before it can be absorbed into the bloodstream. Some peptide drugs such as insulin cannot be given orally for this reason.
What increases drug absorption?
Physiologically, a drug's absorption is enhanced
if there is a large surface area available for absorption
(e.g. villi/microvilli of intestinal tract) and if there is a large blood supply for the drug to move down its concentration gradient.
What medication route has the slowest absorption rate?
The absoroption of subcutaneous injections is slower than that of IV route and it needs absorption similar to Intramuscular injection.
Is it better to stop diarrhea or let it go?
