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?

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.
