What are the symptoms of blood disease

There are many characteristics of blood diseases, but we all know that if we want to effectively reduce the impact of these diseases, the most important thing is to understand the characteristics and symptoms of blood diseases. For example, common fever and bleeding, or enlarged spleen, and lesions of lymph nodes, skin and mucous membranes should all be alert to whether they are symptoms of blood diseases and take timely treatment measures.

1. Sudden onset: Leukemia often has an acute onset and a short course, especially in children and young people.

2. Fever: The first symptom of acute leukemia is often fever, which may manifest as remittent fever, prolonged fever, intermittent fever or irregular fever, with a body temperature of 37.5 to 40°C or higher. Sometimes there is a feeling of coldness, but no chills.

3. Bleeding: It is a common symptom of leukemia. Bleeding sites can be found all over the body, especially in the nasal cavity, oral cavity, gums, subcutaneous tissue, and fundus. Bleeding may also occur in the brain, inner ear, and internal organs.

4. Anemia: Anemia can occur in the early stages, with symptoms such as pale complexion, dizziness, and palpitations.

5. Hepatosplenomegaly: 50% of leukemia patients will experience hepatosplenomegaly, with acute lymphocytic leukemia being the most prone to hepatosplenomegaly.

6. Lymph nodes: Widespread enlargement of lymph nodes throughout the body is more common in acute lymphocytic leukemia, but acute lymphocytic leukemia is not as obvious as chronic lymphocytic leukemia. Superficial lymph nodes are located in the neck, submandibular, axilla, groin, etc., while deep lymph nodes are located near the mediastinum and internal organs. Enlarged lymph nodes are generally soft or of medium hardness, with a smooth surface, no tenderness, and no adhesions.

7. Skin and mucous membrane lesions: Skin damage associated with leukemia manifests as nodules, lumps, maculopapular rashes, etc. Mucosal damage manifests itself as swelling and ulcers in the nasal mucosa, respiratory mucosa, oral mucosa, etc.

8. Inflammation of the nervous system: Leukocyte infiltration may occur in the arachnoid membrane, meninges, etc., and the symptoms are quite similar to brain tumors, meningitis, etc. Patients will experience symptoms such as increased intracranial pressure, meningeal irritation, and limb paralysis.

9. Bone and joint lesions: After the lesions infiltrate the bones and joints, bone and joint pain often occurs, manifested as dull pain, soreness, and occasionally severe pain in the sternum, humerus, shoulders, elbows, hips, knees, etc. Children with acute lymphoblastic leukemia often present with bone and joint tenderness.

10. Others: Leukemia cells can infiltrate the respiratory, digestive and urogenital systems, as well as the eye sockets, lacrimal glands and fundus. Patients may have diffuse or nodular changes in the lungs, accompanied by pleural effusion, digestive dysfunction, proteinuria, hematuria, amenorrhea or excessive menstruation, exophthalmos and decreased vision.
