Obese mums-to-be are at an increased risk of suffering from minor complications such as heartburn and chest infections during pregnancy, a new study suggests.
Research by the University of Edinburgh found that obese mothers-to-be were nearly 10 times more likely to suffer from chest infections, and more than twice as likely to suffer from headaches and heartburn, compared with pregnant women of a healthy weight.
To reach the conclusion, researchers studied the records of more than 650 pregnant women, of whom nearly half were overweight or obese at the beginning of their pregnancy. The study took into account factors such as age and smoking.
The study, published in the British Journal of Obstetrics and Gynaecology, also found that obese women had a more than three-fold increased risk of suffering from a condition known as symphysis-pubis dysfunction, which affects the pelvic joints and may cause walking difficulties if severe.
Dr Rebecca Reynolds, of the Tommy's Centre for Maternal and Fetal Health at the University of Edinburgh: "Although symptoms such as heartburn are common and generally perceived to be benign, they can still have a major impact on the quality of life for pregnant women and can be linked to more serious conditions.
"What may be termed as minor complications can make a pregnancy much more uncomfortable and are also associated with higher treatment costs."
