R63.6: Insufficient intake of food and water
Insufficient intake of food and water, as coded by R63.6 in the ICD-10, refers to a health condition where the body is not receiving the necessary nutrients and hydration for optimal function. This can occur as a result of several factors, such as a lack of appetite, physical difficulty in consuming food and liquids, or socioeconomic reasons like poverty. Manifestations can be subtle or severe, and can include fatigue, dizziness, rapid weight loss, dry skin and mucus membranes, and in severe instances, alterations in mental status like confusion. Over time, prolonged inadequate intake can lead to malnutrition and dehydration, negatively affecting numerous body systems, posing a serious threat to overall health.
