Gastritis does not affect menstruation, although a small percentage of patients with gastritis have significant clinical symptoms, such as abdominal pain, bloating, nausea, vomiting, acid reflux, belching, etc., resulting in a significant decrease in appetite. This is because eating less can cause menstrual disorders, such as low menstrual flow or delayed periods. Menstruation can also be affected if the patient with gastritis has too much psychological burden, tension, anxiety, or even irritability and insomnia. For gastritis, treatment with acid suppressants combined with stomach protectors can provide significant relief, so patients do not need to worry. If the patient has obvious menstrual disorders and gynecological diseases are suspected, it is recommended that he/she should go to the hospital in time.
