Anemia can cause nausea and vomiting. Anemia is a decrease in the volume of red blood cells in the peripheral blood of the body, and when the blood supply to the gastrointestinal tract and other tissues and organs is insufficient, gastrointestinal reactions such as nausea and vomiting may occur.
In patients with anemia, the blood supply to the digestive tract is reduced, the supply of oxygen is also reduced, the patient’s digestive tract glands secrete less mucus, and the patient is prone to nausea, vomiting, decreased digestive function, indigestion, and decreased appetite. After treatment of the primary disease and/or blood transfusion, most patients’ symptoms will be relieved or even disappear.
Anemia not only causes symptoms such as nausea and vomiting, but may also manifest symptoms such as headache, dizziness, pale skin, rapid breathing and rapid heart rate. Anemia patients are advised to seek prompt medical attention to avoid delays.
