In Labor? Eat for Endurance!!

For 30 years I have been reminding my pregnancy exercise and childbirth education classes – not to mention anesthesiologists – that the uterus is a bag of muscle, and that muscles need two things to function well: oxygen and sugar. To contract, muscles burn sugar in the presence of oxygen. Oxygen is renewed by regular, paced breathing. Sugar, on the other hand, has to be supplied first by glycogen at the muscle site, then by circulating blood glucose, optimally provided every few hours by food.

The amount of glycogen that rests at the muscle site in case the muscles need it for quick action lasts about 20 minutes at most. After that, during physical activity, the body will begin to break down fat to provide blood glucose. But. that also has time limits and acid begins to accumulate. Ultimately, nutrition of some kind is the only way that any ultra endurance activity ensures that adequate sugar is continuously supplied to the muscle. Without adequate energy, muscles do not work well.  Without nutrition, acid builds up.

For many decades, there has been a ban on food and water during labor once a laboring mom is in the hospital due to the risk of aspiration – inhaling food or water into the lungs. At last, anesthesiologists have looked at the risk of aspiration in labor and discovered that there has been only one case recorded between 2006 and 2013 associated with labor and birth. Logical conclusion: withholding food and water during the endurance event known as labor is not a great idea. Kudos to the researchers at Memorial University, St. John’s, Newfoundland, Canada, who suggest a change in practice. Yes, there are factors that might over-ride this conclusion, including obesity and preeclampsia, but for most healthy women, eating lightly in labor is a good thing.
