Oral consumption of donkey-hide gelatin is ineffective for iron deficiency anemia. Iron deficiency anemia requires iron supplementation treatment, but while donkey-hide gelatin is rich in collagen, it is not rich in iron, thus it is ineffective for treating iron deficiency anemia through oral consumption. For iron deficiency anemia, a diet rich in iron, such as animal liver, lean meats, and blood products, which are rich in iron, should be pursued. Additionally, it is necessary to avoid strong tea, as it contains tannins that can chelate iron and affect its absorption.

What are the symptoms of iron deficiency anemia in children?

Iron deficiency anemia can manifest as: 1. Gradual pallor of the skin and mucous membranes, especially noticeable on the lips, oral mucosa, and nail beds. Older children may experience dizziness, darkening before the eyes, and tinnitus. Additionally, anemia can lead to extramedullary hematopoiesis, and enlargement of the liver, spleen, and lymph nodes can occur. The younger the age and the longer the duration of the disease, the more severe the anemia and the more prominent the enlargement of the liver and spleen. 2. In terms of gastrointestinal tract: reduced appetite, pica, vomiting, diarrhea, and stomatitis may occur. 3. Nervous system manifestations include: restlessness or lethargy, lack of concentration, reduced memory, and intelligence often lower than peers of the same age. 4. Cardiovascular system: an increased heart rate may be observed, and in severe cases, cardiac enlargement and even heart failure can occur. 5. Immune system: Iron deficiency can affect hematopoietic function, often leading to reduced cell-mediated immune function and combined infections.

Iron deficiency anemia clinical manifestations

Iron deficiency anemia presents in a variety of ways, including symptoms of anemia and iron deficiency. The main manifestation is tissue and organ hypoxia caused by iron deficiency, and severe iron deficiency anemia can lead to mucosal tissue changes and ectoderm nutritional disorders. Among the symptoms, we can find that in the early stages, the symptoms are relatively concealed and hard to detect. Patients with a slow progression can often adapt well in the early stages and are able to engage in daily work. Common symptoms of anemia include dizziness, headache, fatigue, and tiredness, along with palpitations and shortness of breath after activity, and even symptoms such as blurred vision and tinnitus. For patients with iron deficiency, specific symptoms include angular cheilitis, atrophy of the tongue papillae, glossitis, and severe iron deficiency patients may experience koilonychia, decreased appetite, nausea, and even constipation. Some patients, particularly children during their growth periods, may exhibit delayed growth and behavioral abnormalities, specifically being irritable and easily angered, having difficulty concentrating in class, and declining academic performance. A few patients may also develop pica, which is a special manifestation of iron deficiency anemia. In terms of physical signs, patients may exhibit pallor of the skin and mucous membranes, dry hair, and keratinization of the lips. Nails may be flat, lackluster, and prone to breakage, and a small number of patients may experience mild splenomegaly. These are the clinical manifestations of iron deficiency anemia.

The causes of iron deficiency anemia

The causes of iron deficiency anemia primarily refer to the disruption of the normal dynamic balance between iron absorption and excretion, leading to the consumption of stored iron as well as an increased need for iron and insufficient iron intake, especially in cases of chronic blood loss, resulting in a long-term negative iron balance. The causes of iron deficiency can be divided into two main aspects: insufficient iron intake and excessive iron loss. In the first aspect, decreased iron intake includes dietary insufficiency, meaning inadequate food intake, and reduced absorption, which includes decreased absorption due to lack of stomach acid and reduced absorption following gastric surgery. Excessive iron loss includes the following eight aspects: 1) gastrointestinal bleeding, which includes bleeding caused by tumors, gastrointestinal ulcers, gastritis, as well as bleeding due to parasites and hookworm infections. It also includes bleeding caused by hemorrhoids in men and arteriovenous malformations; 2) excessive menstrual bleeding; 3) frequent blood donations; 4) multiple pregnancies in women; 5) chronic intravascular hemolysis causing hemoglobinuria; 6) hereditary hemorrhagic telangiectasia; 7) primary pulmonary hemosiderosis; and 8) coagulation disorders or the use of anticoagulants leading to iron deficiency. These eight categories all result from excessive loss of iron, causing iron deficiency which leads to iron deficiency anemia.

Diet for Iron Deficiency Anemia

Patients with iron-deficiency anemia need to undergo pharmacological treatment with oral or injective iron supplements. In addition, patient health education should be enhanced to guide them in following a scientific and reasonable diet. For example, patients who are picky eaters or have insufficient intake should change their dietary structure and lifestyle in order to increase iron intake and bioavailability. This ensures that all key nutrients involved in the production of red blood cells are sufficient. Moreover, it is necessary to increase the intake of iron-rich foods, mainly including animal liver, blood, as well as soybeans, black fungus, egg yolks, brown sugar, lean meat, sheep kidneys, dried fruits, and sesame paste.

Can people with iron deficiency anemia drink tea?

The first aspect of treating patients with iron deficiency anemia is etiological treatment. It is necessary to remove the causes of iron deficiency as much as possible. While simple iron supplementation can restore blood indices, if the primary disease is not actively treated, it cannot fundamentally solve anemia. If left untreated, anemia in patients is prone to recurrence. Secondly, iron supplementation is the clinical priority, with oral iron supplements being the most commonly used treatment. Ferrous preparations such as ferrous succinate and ferrous fumarate are most often used. These medications are generally taken with meals or after meals to reduce gastrointestinal irritation. This raises the issue of whether patients with iron deficiency anemia can drink tea. When iron supplements are taken with tea, they can bind with the tannins in the tea to form an insoluble precipitate that is difficult to absorb. Thus, it is clinically advised that patients with iron deficiency anemia should avoid drinking tea, as it can reduce the absorption of iron and thus result in suboptimal treatment outcomes.
