- premenopausal breast cancer.
- developing type II diabetes in the longer term.
- ovarian cancer – curiously, if you develop mastitis, your body produces factors which appear to reduce your risk of developing ovarian cancer.
- osteoporosis in later life – for every 10 cumulative months of breastfeeding, the risk of osteoporosis is reduced by as much as 12%.
- Breastfed babies have fewer and less severe upper and lower respiratory tract infections; they are less likely to need hospitalisation.
- Ear infections are 3 to 4 times more common in infants who are not breastfed.
- Breastmilk has factors which protect against urinary tract infections.
- Babies who are not breastfed are more likely to suffer from diarrhoea and gastroenteritis. Their feeds lack the protective factors in breastmilk and are more easily contaminated during preparation and storage.
- Constipation is much more common in formula fed infants than breastfed infants, whose stools are typically soft and sweeter smelling.
- Symptomatic gastro-oesophageal reflux is more common in formula fed infants because stomach emptying is slower and there is an increased risk of allergic reaction irritating the oesophagus.
- Breastfed babies respond better to vaccines, as their immune system is more mature.
- Breastfeeding is protective against SIDS, especially exclusive breastfeeding
- fewer chest infections until at least the age of seven
- less risk of developing eczema and asthma
- a lower risk of developing obesity in childhood and in later life; the longer the duration of breastfeeding, the lower the risk.
- the best chance of achieving their full brain potential , including higher scores in intelligence tests.
- a decreased risk of developing childhood cancer.
- greater bone mineral density at age 8 and 17 year – this has the potential to delay or prevent osteoporosis in later life.
