Increased exhaust in pregnant women may be caused by improper diet, or due to indigestion, chronic gastritis and other diseases. 1. Improper diet: If a pregnant woman has recently eaten too much dairy products, onions, beans and other foods that are easy to produce gas, it will cause more exhaust, which is a normal physiological phenomenon. 2. Dyspepsia: this disease is the result of a combination of factors, including gastrointestinal dyskinesia, visceral sensory sensitivity, heredity, pathogenic microbial infections, mental and psychological factors. Patients will have symptoms such as abdominal distension, abdominal pain, and some patients will have excessive exhaust. 3. Chronic gastritis: the occurrence of this disease is related to Helicobacter pylori infection, autoimmune abnormalities, long-term use of non-steroidal anti-inflammatory drugs, improper diet and other factors. Typical symptoms are bloating, belching, acidity, nausea, etc., which in some cases can be manifested as symptoms of increased flatulence. In addition, the causes of increased exhaustion in pregnant women include irritable bowel syndrome, respiratory failure, gastroesophageal reflux disease, and so on. In the clinical situation, if the increase in exhaustion of pregnant women is ruled out as a physiological phenomenon, it is necessary to go to the hospital in a timely manner in order to clarify the specific causes.
