Each year, over 250,000 patients in the United States receive Total Parenteral Nutrition (TPN). Since TPN delivers nutrients intravenously, eating while on it can cause serious complications.

Over 50% of individuals on TPN may experience blood sugar imbalances, a testament to the complex risks involved with this life-sustaining treatment. While often necessary, parenteral nutrition is not without significant drawbacks that must be carefully managed by healthcare professionals.

Studies have shown that patients receiving intravenous nutrition can still experience hunger, even when fully nourished, a phenomenon that perplexes many who are hungry on TPN. This sensation arises from a complex interplay of physiological signals and psychological factors that intravenous feeding does not fully replicate.

According to a 2019 study, Total Parenteral Nutrition (TPN) remains an independent risk factor for central line-associated bloodstream infections (CLABSIs), which can lead to sepsis. Understanding why TPN causes sepsis is crucial for both healthcare providers and patients receiving this life-sustaining treatment. The risk is primarily linked to the central venous catheter used for administration and the physiological changes bypassing the gut.

According to research, the prolonged use of total parenteral nutrition (TPN) can induce intestinal complications, including diarrhea. While the intravenous feeding itself does not act as a laxative, the conditions created by bypassing the digestive tract can lead to significant gastrointestinal issues, raising the critical question: **Can TPN cause diarrhea?**
