Is donating blood every six months harmful to my body?

Is it harmful to donate plasma twice a month? Donating plasma twice a month is less harmful to the body and is almost negligible. Usually, the body's blood volume can return to normal within two hours, but some people may have symptoms of anemia due to their own weakness.

1. Nervous system: If the blood donor's own blood circulation is poor, donating plasma twice a month, his own blood supply is insufficient, and the corresponding nutrients are reduced, which can affect the nervous system, and symptoms such as dizziness, dizziness, memory loss, and lack of concentration will occur;

2. **Mucosa: the body is weak, its own blood supply will be insufficient, and when the **mucosa cannot be supplied with blood, the lips, face, and nail bed may be pale and rough;

3. Respiratory system: donate plasma twice a month, when the blood volume in the body is reduced, the oxygen carried in the blood will be reduced accordingly, and when the supply to the body is insufficient, the blood donor may have shortness of breath and labored breathing, so as to accelerate the inhalation of oxygen;

4. Cardiovascular system: when a blood donor donates plasma twice a month, resulting in insufficient blood supply to the body, the blood donor may show palpitation and increased heart rate;

5. Digestive system: If the blood cannot provide sufficient nutrients to the cells of the digestive system after donating plasma, digestive symptoms such as abdominal distention, changes in the frequency and shape of stools may occur;

6. Immune system: plasma contains proteins, immune antibodies, coagulation factors and other components, and when too much plasma is donated, it can lead to decreased immunity and easy infection.

There are many benefits of plasma donation, such as promoting the hematopoietic function of the bone marrow and reducing the incidence of cardiovascular and cerebrovascular diseases, but it should be noted that it should not be too frequent and too much. China's blood donation law stipulates that the interval between two blood donations should be greater than six months. Therefore, in daily life, it is necessary to donate blood in strict accordance with the regulations of the state to avoid causing damage to oneself.

Generally harmless. But don't keep such blood in a row. Nutrition should be strengthened, eat more mutton, beef, dog meat, leek, eggs, fish, shrimp, jujube, longan.

1. Under normal circumstances, it will not cause harm to the body. Normal people can donate blood 4 times a year, each time in about 200 ml to 300 ml, will not affect the body, if the one-time blood donation is too much or too frequent blood donation, it may lead to low immunity or low blood protein, the occurrence of coagulation dysfunction of the body.

2. Proper blood donation can promote the body's metabolism and the hematopoietic function of the bone marrow, and after blood donation, the blood viscosity of red blood cells and platelets will decrease, promote blood circulation, and reduce the occurrence of cardiovascular and cerebrovascular diseases.

There are currently no studies to prove that it is best to donate plasma at intervals. However, the interval should not be less than 15 days. Plasma donation is the process of separating the blood components of the donor, leaving only the plasma, and then transfusing the blood cells back into the donor's body.

The isolated plasma will be used in clinical practice. Although plasma donation will promote the body's metabolism to a certain extent, stimulate the bone marrow to compensate for hematopoietic function. However, donating plasma will lose a certain degree of water and some albumin, globulin, inorganic ions and various coagulation factors.

It takes time for the donor's plasma composition to recover. Generally, water can be recovered within one day, but albumin and some clotting factors generally take about 10 days to recover. Therefore, in order to ensure the health of blood donors, the interval between plasma donations should be greater than 15 days.

The specific blood donation interval should be carried out appropriately under the condition that it does not affect one's own health.
