Lactation invokes homeorhetic processes to ramp up and supply milk synthesis components to fulfil nutritional, immunological and microbiological requirements of developing offspring, overseen by complex neuroendocrine networks. The maternal gut meets these intense metabolic demands, supported by hyperphagia and rapid adjustments to process larger food quantities. This research seeks to help mothers and clinicians better understand the hormonal components of their diet, gastrointestinal and other biological drives toward essential nutrient flow to their infants via lacatation.
