What does your textbook say about LACTATION AND INFANCY?

Nutrition in pregnancy, lactation and infancy • There is a decreased ability to taste saltiness. This may in fact, be a physiologic mechanism for increasing salt intake. • The ability to excrete water is lowered and oedema in the legs and ankle is common and normal. • Gastrointestinal motility diminishes, to allow for increased absorption of nutrients. This often results in constipation. • A relaxed lower oesophageal sphincter can cause regurgitation and heart burns. • Increased progesterone level relaxes the uterine muscle to allow expansion with foetal growth. • High oestrogen levels during pregnancy promote a gynaecoid type of fat distribution.
