Sleepiness in third trimester common, but may signal underlying obstructive sleep apnea

This article discusses research showing that sleepiness during the third trimester is common, but may not be normal. Some of the sleepiness could be due obstructive sleep apnea (OSA). The authors conclude that screening for sleep related breathing disorders should be done in pregnant women, and I agree. Especially if a pregnant woman has known OSA but is not using CPAP. Untreated OSA can increase risk for a small baby, called intrauterine growth retardation.
