It is not uncommon for women who are 38 weeks pregnant to experience a hard and painful stomach, as well as difficulty keeping food down. These symptoms can be attributed to the pressure exerted by the growing baby on the digestive system. The expanding uterus can compress the stomach, making it difficult for food to pass through properly. Additionally, hormonal changes during pregnancy can affect digestion and lead to nausea or vomiting. However, if you are experiencing severe pain or are unable to keep any food down at all, it is important to consult with your healthcare provider as these could be signs of a more serious condition such as preeclampsia or other complications. Your healthcare provider will be able to assess your specific situation and provide appropriate guidance and treatment if necessary. In the meantime, try eating smaller meals more frequently throughout the day, avoiding greasy or spicy foods that may exacerbate symptoms, staying hydrated, and resting in an upright position after meals to help alleviate discomfort.
