A day delay in menstruation with chest distension and nausea is often due to phytodysfunction. Phytodysfunction can present with symptoms similar to those of the cardiovascular system and the digestive system, and is mostly manifested as symptoms associated with neurosis. Patients may experience anxiety and depression, and may have palpitations, nausea, vomiting, and other symptoms related to the gastrointestinal tract, such as abdominal distension and nausea. Mostly, vegetative insufficiency is considered, and psychological reassurance needs to be given, and relevant medication is given if necessary. Patients with abdominal distension and nausea can be treated with medications related to improving gastrointestinal motility, such as morpholine and Sulikidan. In addition, attention should be paid to the symptomatic treatment with drugs related to the regulation of the vegetative nerves, such as alprazolam, haloperidol, melitrexin, etc. if necessary, and the key is psychological comfort.
