Nausea and vomiting after exercise may be related to physiologic factors such as hypoxia and pathologic factors such as upper respiratory tract infections and functional dyspepsia.
1. Physiological factors:
(1) hypoxia: exercise consumes a large amount of oxygen, once the body is hypoxic, nausea, vomiting, shortness of breath and other symptoms may occur.
(2) Carbon dioxide retention: insufficient lung ventilation during exercise can lead to carbon dioxide retention, which can cause mild headache, nausea, vomiting and other symptoms.
2. Pathologic factors:
(1) Upper respiratory tract infection: cough, nausea, vomiting, pharyngeal discomfort and other symptoms can be seen in upper respiratory tract infection. After exercise, it can cause or aggravate the symptoms of upper respiratory tract infection, resulting in nausea and vomiting.
(2) Functional dyspepsia: generally refers to non-organic diseases caused by gastric and duodenal dysfunction, which can have symptoms such as nausea, vomiting, abdominal distension, eructation and diarrhea.
(3) Peptic ulcer: a large amount of gas can be inhaled into the stomach within a short period of time during exercise, causing gastric distension, stimulating the gastric mucosa, aggravating the symptoms of ulcers, and symptoms such as gastric pain, gastric distension, nausea and vomiting.
There are many other reasons for nausea and vomiting after exercise, such as early pregnancy reaction for women of childbearing age. It is recommended to consult a doctor for a clear diagnosis.
