Nausea in the morning without appetite may be due to indigestion, chronic gastritis, gastric ulcer, etc., women may also be caused by pregnancy reactions. 1. Indigestion: patients with indigestion have insufficient secretion of digestive juices and slowed down peristalsis of the gastrointestinal tract with insufficient power, and are unable to digest the food they ingested the night before, which may lead to bloating, nausea, and loss of appetite. Emotional factors such as long-term loss, depression or anger, bad habits, poor diet, gastrointestinal diseases and other causes can lead to indigestion. 2. Chronic gastritis: due to chronic inflammation of the gastric mucosa, the digestive function is weakened, which can also cause symptoms such as decreased appetite and nausea. 3. Gastric ulcer: if the gastric mucosa is damaged, gastric acid stimulation of the stomach wall can cause bloating, nausea, loss of appetite and other symptoms. 4. Female pregnancy: female patients should pay attention to whether the chorionic gonadotropin is elevated during pregnancy, resulting in nausea, vomiting, loss of appetite and other pregnancy reactions. If the symptoms can not be relieved in time, it is recommended that the patient seek medical attention in time to avoid serious consequences.
