Dizziness and nausea may occur when a person has anemia. Anemia is a very common symptom in clinical practice.
Generally, in a blood test, if the hemoglobin concentration of an adult male is lower than 120 grams per liter, that of an adult female is lower than 110 grams per liter, and that of a pregnant woman is lower than 100 grams per liter, anemia can be diagnosed.
If a person has mild anemia, the clinical symptoms may not be particularly obvious. When moderate to severe anemia occurs, the patient may have a series of clinical manifestations.
Dizziness, headache, loss of appetite, indigestion, nausea, and vomiting are all common symptoms of anemia.
In addition, the patient may also show pale complexion, palpitations and shortness of breath after physical activity.
Some patients may also experience orthopnea, increased heart rate, arrhythmia, and cardiac insufficiency.
