egenmättning

Egenmättning is a Swedish term that translates to "self-metabolism" or "auto-metabolism" in English. It refers to the process by which an organism utilizes its own body tissues for energy and sustenance. This phenomenon is most commonly observed during periods of starvation, prolonged fasting, or severe illness when external food sources are unavailable or insufficient.

In such conditions, the body initiates a series of catabolic processes to break down stored reserves. Initially, glycogen stores in the liver and muscles are depleted. Following this, the body begins to metabolize fat reserves, releasing fatty acids for energy. As starvation progresses, protein breakdown becomes more significant, with muscle tissue being a primary source of amino acids. These amino acids can be converted into glucose through gluconeogenesis or used directly for energy.

While egenmättning is a survival mechanism, prolonged or excessive self-metabolism can be detrimental. The breakdown of essential tissues, particularly muscle and organ tissue, can lead to severe health complications, organ failure, and ultimately, death. The rate and extent of egenmättning vary depending on factors such as an individual's initial body composition, metabolic rate, and overall health status. Medical conditions that impair nutrient absorption or increase metabolic demands can also accelerate the process. Understanding egenmättning is crucial in fields like medicine, nutrition, and veterinary science for managing conditions involving malnutrition or critical illness.
