Polyphagia or hyperphagia is an abnormally strong, incessant sensation of hunger or desire to eat often leading to overeating. [1] In contrast to an increase in appetite following exercise, polyphagia does not subside after eating and often leads to rapid intake of excessive quantities of food.
Avoidant/restrictive food intake disorder is not simple "picky eating" commonly seen in toddlers and young children, which usually resolves on its own. [2]In ARFID, the behaviors are so severe that they lead to nutritional deficiencies, poor weight gain (or significant weight loss), and/or significant interference with "psychosocial functioning."
Overeating occurs when an individual consumes more calories in relation to the energy that is expended via physical activity or expelled via excretion, leading to weight gain and often obesity.

Older people may feel less violent stomach contractions when they get hungry, but still suffer the secondary effects resulting from low food intake: these include weakness, irritability and decreased concentration.

Psychological factors – these are not main factors that contribute to enuresis, but stress may be a cause. Maturational delay – the child's recognition that the bladder is full and they need to go to the bathroom is a developmental issue.
Hypothermia (dangerously low core body temperature) can occur in malnutrition, particularly in children. Mild hypothermia causes confusion, trembling, and clumsiness; more severe cases can be fatal. Keeping malnourished children warm can prevent or treat hypothermia. Covering the child (including their head) in blankets is one method.
