Doctor CKI Dinh Tran Ngoc Mai, Department of Nutrition - Dietetics, University of Medicine and Pharmacy Hospital, Ho Chi Minh City, replied: Symptoms of anemia are often non-specific and clinically obvious. Common signs include pale skin, pale mucous membranes, fatigue, drowsiness, shortness of breath during exertion, dizziness, lightheadedness, tinnitus, hair loss, amenorrhea...
Dizziness and lightheadedness can be signs of anemia.
To determine whether there is anemia or not, in addition to clinical examination, it is necessary to do blood tests including complete blood cell analysis, peripheral blood smear, special tests to find the cause such as gastroscopy, colonoscopy, abdominal ultrasound, serum iron quantification, vitamin B12, folate, hemoglobin electrophoresis, bone marrow aspiration... depending on the specific case.
To avoid anemia, we need to have a varied diet, eat enough meat, fish, eggs, milk, dark green vegetables, and add fruits rich in vitamin C to meals to help absorb iron better.
For vegetarians, it is easy to have B12 and iron deficiency, causing anemia, so it is necessary to pay attention to supplementing a variety of foods such as cereals, iron supplements, and vitamin B12 as prescribed by the doctor.
