Introduction: A woman's unique physiological structure makes her highly susceptible to anemia at various stages of life. However, many women are unaware of their anemia, or knowing they have it, fail to address it, considering it a minor issue. Others may not pay attention to certain details during the supplementation process, which can worsen the anemia. Therefore, the editor from Meishitianxia will now inform you about the symptoms of anemia and the precautions for iron supplementation to help you learn how to improve it.
Anemia impairs the blood's ability to carry oxygen, which can damage the function of various systems and organs throughout the body. The impact varies depending on the severity and duration of the anemia, the patient's age, and the presence of any underlying diseases (especially cardiovascular, cerebrovascular, and pulmonary conditions).
1. General Symptoms: Fatigue and lethargy are the most common symptoms of anemia. In severe cases, some patients may also experience a low-grade fever.
2. Cardiovascular System: Palpitations and shortness of breath upon exertion are most common. Some patients with severe anemia may also experience angina pectoris or heart failure. Upon examination, a mild systolic murmur, edema in the lower extremities, and changes on an ECG may be present.
3. Nervous System: Headache, dizziness, vertigo, tinnitus, difficulty concentrating, insomnia, or syncope. Severe anemia can lead to symptoms such as confusion or dementia. Anemia caused by vitamin B12 deficiency is often accompanied by limb numbness and sensory impairment.
4. Digestive System: Loss of appetite, abdominal bloating, and nausea are common. Patients with hemolytic anemia may present with jaundice and an enlarged spleen.
5. Urinary and Reproductive Systems: Decreased kidney concentrating function, leading to frequent urination and reduced urine specific gravity. Decreased libido. Female patients often experience irregular, excessive, or reduced menstrual flow.
6. Others: Dry skin, sparse, dull hair.
Medically, anemia is classified based on its cause into types such as iron-deficiency anemia, megaloblastic anemia, and hemolytic anemia, with iron-deficiency anemia being the most common. The most common and effective treatment for iron-deficiency anemia is oral or intravenous iron supplementation. However, clinically, many patients report that oral iron supplements are not as effective as expected. Unbeknownst to them, many factors can affect the efficacy of iron supplementation, which should be taken into consideration during use.
1. For oral iron supplements, ferrous sulfate, ferrous fumarate, and ferrous gluconate are preferred because iron is absorbed in its ferrous (divalent) form but functions in its ferric (trivalent) form. Traditional Chinese medicine products for blood enrichment include Hongtao K, Xueer, Pu Xue, and Nüren Yuan.
2. Iron supplementation for anemia should follow the principle of "small doses, long-term use." Strictly adhere to the doctor's prescription for medication; do not increase the dosage on your own to avoid iron poisoning. Also, never take a large single dose, as this can easily lead to acute iron poisoning. Symptoms of iron poisoning include dizziness, nausea, vomiting, diarrhea, abdominal pain, and shock. In severe cases, it can lead to coma, convulsions, and even death.
3. When taking oral iron supplements, place the tablet on the tongue and swallow it directly with water; do not chew the tablet to avoid staining the teeth and affecting appearance.
4. Take the medication after meals to avoid taking it on an empty stomach, which can reduce nausea and vomiting caused by gastrointestinal irritation. Simultaneously, take it with vitamin C or fruit juice, as an acidic environment enhances iron absorption.
5. Foods containing calcium (such as tofu) and high-phosphate foods (such as milk) can form precipitates with iron supplements and should be avoided.
6. During oral iron supplementation, do not drink strong tea or coffee, as they contain large amounts of tannic acid, which can form insoluble iron precipitates and hinder iron absorption. Milk and other alkaline substances can also affect iron absorption and should be avoided or consumed in minimal amounts. Dairy products (especially milk) contain very little iron and should not be consumed in large quantities, as this can reduce the amount of iron already present in the gastrointestinal tract.
7. Be aware of the adverse effects of other drugs on iron absorption: Tetracycline antibiotics can form insoluble complexes with iron supplements, impairing absorption. Therefore, simultaneous use should be avoided. If both must be used, they should be administered at least 3 hours apart.
8. Strengthen dietary care. A correct and balanced diet can prevent and treat iron-deficiency anemia. For patients who already have iron-deficiency anemia, relying solely on dietary therapy is not very effective, but it can serve as an adjunctive treatment to prevent recurrence. Bad habits such as picky eating, selective eating, and loss of appetite should be corrected. The diet should be varied, with an appropriate increase in iron-rich and nutritious foods, such as: meat, eggs, fish, various seafood (such as kelp, seaweed), animal liver and blood, coarse grains like buckwheat and sweet potatoes, bean products, mushrooms, black fungus, and a variety of fresh fruits and vegetables.
9. After several months of treatment, when clinical symptoms improve and hemoglobin levels return to normal, do not stop the medication immediately. Continue taking it under a doctor's guidance for another 3-6 months to replenish the body's stored iron and prevent a recurrence of anemia.
10. During oral iron therapy, iron reacts with hydrogen sulfide in the large intestine to form iron sulfide, which causes the stool to turn dark brown, similar to gastrointestinal bleeding. There is no need to be alarmed by this, as the stool color will return to normal after stopping the iron supplement.
