Introduction
In general, low-grade fever and dark circles around the eyes may be caused by malnutrition, pneumonia, anemia, or other conditions, and treatment should be based on the specific diagnosis. Additionally, these symptoms could also result from other causes such as glomerulonephritis, hepatitis B, or anxiety disorder. It is recommended that patients seek timely medical attention when experiencing discomfort to avoid delays in treatment, and maintain a light and healthy diet in daily life.

In general, low-grade fever and dark circles under the eyes may be caused by malnutrition, pneumonia, anemia, or other conditions, and treatment should be tailored according to the specific cause. Details are as follows:

1. Malnutrition

A deficiency in vitamins, minerals, and other trace elements can lead to malnutrition. This may result in dark circles under the eyes, reduced immunity, and symptoms such as low-grade fever. It is recommended that patients consume more protein-rich foods, fresh vegetables and fruits, and drink more milk to correct malnutrition, which usually helps improve these symptoms.

2. Pneumonia

Pneumonia refers to inflammation of the terminal airways, alveoli, and lung interstitium. It can cause symptoms such as coughing, shortness of breath, chest tightness, and fever, which may disrupt sleep and consequently lead to dark circles under the eyes. Patients are advised to take medications such as amoxicillin dispersible tablets or cefaclor dispersible tablets as directed by a physician.

3. Anemia

Anemia is a clinical syndrome characterized by a reduction in peripheral blood red cell volume below the normal lower limit, resulting in inadequate oxygen supply to tissues and organs. Symptoms may include headache, dizziness, fatigue, fainting, and insomnia. Reduced immunity may lead to fever, and poor sleep can contribute to the development of dark circles. Patients are advised to improve their diet by consuming more iron-rich foods and, if necessary, take medications such as ferrous sulfate tablets or ferrous succinate granules as prescribed.

Besides the above, other possible causes include glomerulonephritis, hepatitis B, anxiety disorders, etc. Patients should seek timely medical attention when experiencing discomfort to avoid delayed treatment. Additionally, maintaining a light diet and ensuring adequate rest are recommended in daily life.

What does MP-IgM negative mean?
If the individual being tested already shows clear respiratory symptoms such as persistent dry cough, low-grade fever, chest tightness, etc., but MP-IgM is still negative, it may be due to a short duration of infection (antibody levels typically rise 7–10 days after infection) and the antibody concentration has not yet reached detectable levels. In such cases, infection cannot be completely ruled out. The test should be repeated after 1–2 weeks, and the results should be interpreted in combination with clinical symptoms.
