Patient's question:
Hello, I donated 200CC of blood last time, and I fainted after the donation. I had sexual activity that same night, but it didn't work. My libido has clearly decreased. It's been over a month now, but I'm still the same. I'm very troubled. Is it because of the blood donation? Should I take any medication? I'm only 21 years old. Will this affect my fertility in the future? Please, doctors, help me.？？Should I go to the hospital? Which department?Doctor's answer:
Eligible, healthy adults can donate 200 milliliters of blood at a time, which accounts for only one-twentieth of the total blood volume in the body. Scientific studies have proven that this amount will not affect physical health, and if adequate nutrition is replenished promptly after donation, normal health can be restored as soon as possible. Living organisms cannot do without protein, and hematopoiesis requires a large amount of protein. Therefore, it is particularly important to pay attention to protein supplementation after blood donation. Generally, animal protein has an amino acid composition that is more aligned with human needs, making it nutritionally superior to plant protein. After blood donation, it is advisable to consume foods rich in high-quality protein, such as milk, pork, beef, chicken, fish, animal liver, heart, and kidneys.After blood donation, the number of red blood cells and other formed elements in the blood decreases relatively, prompting the body's bone marrow to immediately double its efforts to synthesize red blood cells and other elements. At this time, a large amount of iron is needed. A normal person requires about 15 milligrams of iron per day, but this need increases significantly after blood donation. However, only about 10% of the iron supplied by the diet can be absorbed by the intestines. Therefore, after blood donation, it is especially important to consume foods high in iron that are also easily absorbed, such as pork, beef, chicken, animal liver, and animal blood. The iron contained in these foods is called hemoglobin iron, which can be directly absorbed and utilized by the human body after entering the intestines, with an absorption rate of up to 13% to 20%. Among these, animal liver and animal blood are particularly rich in iron, with even higher absorption rates. Fresh vegetables and fruits are rich in vitamin C and organic acids, which can promote the absorption of iron from food. However, foods like chives, celery, spinach, or a cup of strong tea at a restaurant can all affect the absorption of iron from food.
Folate and vitamin B12 do not directly participate in the production of red blood cells, but the maturation and development of red blood cells, as well as plasma, depend on them. Folate and vitamin B12 are widely found in green leafy vegetables, fruits, animal liver and kidneys, and yeast. After blood donation, it is also important to regularly consume these foods.
