What is the cause of high white blood cell count?

White blood cells, also known as leukocytes, are a very important component of the blood and play a big role in us. If our body has some discomfort symptoms at ordinary times, if you go to the hospital for a check-up, you will find that the number of white blood cells has changed significantly. Both low and high white blood cell counts are very common. I think everyone doesn’t know much about what is going on with high white blood cell counts.

What causes high white blood cell count? Many people find that their white blood cell count is elevated during examinations, but most of the time they don’t know what is going on. There are many reasons for elevated white blood cell count, generally caused by acute bacterial infection, heavy bleeding, and the most common leukemia.

1. What is the reason for high white blood cell count?

Usually, high white blood cells are accompanied by high neutrophils, and low white blood cells are accompanied by low neutrophils. This is because white blood cells are usually more affected by neutrophils, and sometimes also by lymphocytes. If white blood cells are high and neutrophils are low, then lymphocytes must be increased.

White blood cells are cells of the body's normal immune system. When the body is invaded by foreign pathogens such as bacteria and viruses, an increase in white blood cells is a self-protection mechanism. At the same time, the use of certain drugs (such as glucocorticoids) will also cause an increase in white blood cells and other cells. Therefore, a simple increase in white blood cells must exclude related factors. If the white blood cell count is still high when conventional antibacterial and related symptomatic treatments are used and the general condition of the child is good, the medication should be stopped, the blood picture should be observed dynamically, and the test should be repeated after one month. Instruct the family members to observe the child! Examination is always an examination, and it must be combined with clinical practice.

Yitongwuyou.com explains: Physiological increase in white blood cell count is often seen in strenuous exercise, after eating, during pregnancy, and in newborns. In addition, different blood collection sites may also result in differences in white blood cell counts. For example, the average white blood cell count in earlobe blood is higher than that in finger blood. In case of extreme heat or cold, the total white blood cell count often increases transiently and quickly returns to normal levels after rewarming.

The most common pathological ones are:

1: Diseases caused by certain bacterial infections, especially local inflammation and systemic infection caused by pyogenic cocci, such as abscess, purulent meningitis, pneumonia, otitis media, empyema, sepsis, etc.

2: Diseases caused by certain viral infections: Japanese encephalitis, infectious mononucleosis, measles, etc.

3: Severe tissue damage or necrosis: such as after major surgery, burns, acute bleeding, vascular embolism, etc.

4: Allergic reactions: such as transfusion reactions, drug allergies, acute allergic diseases, etc.

5: Poisoning reactions: various drug poisoning, heavy metal poisoning, diabetic acidosis, etc.

6: Tumors and blood diseases: chronic myeloid leukemia, acute myeloid leukemia, etc.

7: The use of certain chemical drugs that increase white blood cells promotes an increase in white blood cells. This is more common during chemotherapy and radiotherapy, when patients have a sharp decrease in white blood cells and need to increase their white blood cells as soon as possible for the next course of treatment.

2. What to do if your white blood cell count is high?

If the neutrophil ratio in the white blood cell count is high, it indicates a bacterial infection, and if the lymphocyte ratio is high, it indicates a viral infection. You may also be talking about mixed infection. Anti-inflammatory and antiviral treatment will do the trick.

General treatment: Patients with high fever in the acute phase should rest in bed and be encouraged to drink plenty of water and urinate frequently to promote rapid excretion of bacteria and inflammatory exudates.

Antimicrobial drugs: Targeted medication should be used based on the strain and drug sensitivity results. Commonly used drugs against Gram-negative bacteria include 2 tablets of co-trimoxazole, taken orally twice a day; 0.1 g of furazolidone, taken orally three times a day; 1.0 g of sulfamethoxazole, taken orally twice a day; 0.25-0.5 g of cephalosporin VI, taken four times a day; and 0.2 g of norfloxacin, taken three times a day. For patients with high fever and obvious systemic symptoms, gentamicin 80,000 U can be used, twice a day, intramuscularly; ampicillin 50-100 mg/kg can be taken orally or intramuscularly in 4 doses. For patients infected with Pseudomonas aeruginosa and Proteus, carbenicillin or sulfobenzylpenicillin can be used. The course of treatment is 2 weeks. After the end of the treatment, urine routine and bacterial culture should be checked every week for 2-3 times in total, and then checked again after 6 weeks. Only those with negative results can be considered cured.

We should pay attention to the issue of high white blood cell count. The role of white blood cells in our body cannot be ignored. It can help us resist some external viruses and make us less sick. We should all know that people with leukemia have increased white blood cell count. We should pay attention to some abnormal conditions of white blood cells.
