Introduction
Under normal circumstances, the neutrophil-to-lymphocyte ratio refers to the ratio of neutrophils to lymphocytes. A low neutrophil-to-lymphocyte ratio may be caused by factors such as influenza, hypersplenism, aplastic anemia, pneumonia, or hepatitis B. Patients are advised to seek medical attention promptly and follow the treatment plan prescribed by their healthcare provider.
Under normal circumstances, the neutrophil-to-lymphocyte ratio (NLR) refers to the ratio of neutrophils to lymphocytes. A low neutrophil-to-lymphocyte ratio may be caused by factors such as influenza, hypersplenism, aplastic anemia, pneumonia, or hepatitis B virus infection. Patients are advised to seek timely medical attention and follow medical guidance for treatment. Specific analyses are as follows:
1. Influenza
Viral infections commonly lead to influenza. After onset, patients often exhibit a decreased neutrophil-to-lymphocyte ratio. Patients may take medications such as Lanqin Oral Liquid or Lianhua Qingwen Capsules as directed by a physician.
2. Hypersplenism
Hypersplenism can cause splenomegaly and increased destruction of blood cells. When excessive destruction occurs, neutrophil counts decrease significantly, leading to a reduced neutrophil-to-lymphocyte ratio. Medications such as Renshen Jianpi Pills or Qiyuan Yiqi BuXue Oral Solution may be used under medical supervision.
3. Aplastic Anemia
Aplastic anemia is usually caused by factors such as viral infections or immune system abnormalities. It may present with a decreased lymphocyte percentage and low platelet hematocrit. Patients may be treated under a doctor's guidance with medications such as etamsylate or aminocaproic acid.
4. Pneumonia
Pneumonia may result from low immunity or infections. Blood tests may reveal a decreased neutrophil-to-lymphocyte ratio. Patients may use medications such as salbutamol sulfate tablets or nebulized ipratropium bromide and fenoterol solution as prescribed.
5. Hepatitis B
This infectious disease is caused by the hepatitis B virus and primarily affects the liver. Patients may experience symptoms such as jaundice, loss of appetite, nausea, and indigestion. Sometimes, it may lead to a decreased percentage of neutrophil-to-lymphocyte ratio. Patients should seek prompt medical care and take antiviral medications such as entecavir tablets or tenofovir alafenamide fumarate tablets as directed.
In addition, leukemia may also be a potential cause. During treatment, patients should actively cooperate with their physicians to promote recovery.
