Excess weight and obesity affects fertility by causing hormonal imbalances that have an impact on ovulation and menstruation. Being overweight is thought to account for around 10% of infertility cases.
For many women pregnancy is a time when weight comes under scrutiny.
Beginning a pregnancy with excess weight or gaining excessive weight during pregnancy increases the risk of complications.
Excess weight often causes breathlessness, lethargy, increased abdominal pressure, indigestion, heartburn, depression and added physical pressure on knee joints as the pregnancy progresses.
If your weight gain is more significant you may develop gestational diabetes or pre-eclampsia. Both conditions are serious and your health professional must be advised.
Ultrasounds are more difficult. C-sections are more dangerous.
