Enlarged Spleen in 2025: Symptoms, Causes, and Treatment Costs Explained

Splenomegaly refers to the abnormal enlargement of the spleen, a vital organ that supports your immune system and blood filtration. When enlarged, the spleen can cause discomfort in the abdomen, disrupt blood flow, and lead to anemia or even rupture, making prompt diagnosis and care essential.

The spleen, located beneath the left rib cage, plays a crucial role in immune defense by storing white blood cells and producing antibodies. It filters bacteria coated with antibodies, recycles iron from old red blood cells, and helps maintain healthy blood function.

Typically about the size of a fist, the spleen can grow significantly larger when affected by splenomegaly.

Recognizing Symptoms of an Enlarged Spleen

Many individuals with an enlarged spleen may not notice symptoms until a routine check-up reveals the condition. In some cases, particularly in slim individuals, the enlarged spleen may be palpable through the skin.

Common signs include pain or a sense of fullness in the upper left abdomen. This fullness can occur after eating only small amounts of food due to the spleen pressing against the stomach.

As the spleen enlarges further, it may interfere with blood flow and impair its ability to filter blood efficiently. Excessive removal of red blood cells by the spleen can cause anemia, while insufficient production of white blood cells may increase susceptibility to infections.

Common Causes of Splenomegaly in 2024

Various health conditions contribute to spleen enlargement. Viral infections such as mononucleosis remain prevalent causes. Liver diseases including cirrhosis and cystic fibrosis also frequently lead to splenomegaly.

Inflammatory disorders like juvenile rheumatoid arthritis can cause lymphatic system inflammation, resulting in an enlarged spleen. Other notable causes include:

• Malaria
• Hodgkin’s lymphoma
• Leukemia
• Heart failure
• Splenic tumors or metastases
• Parasitic, bacterial, or viral infections
• Autoimmune diseases such as lupus and rheumatoid arthritis
• Sickle cell anemia

When to Consult a Doctor

If you experience persistent pain or discomfort in the upper left abdomen, especially if it worsens with breathing, seek medical attention promptly. Early evaluation can prevent complications and guide appropriate treatment.

For those without a primary care physician, online platforms like Healthline FindCare can help locate qualified doctors nearby.

Effective Treatments and Management

Treatment for an enlarged spleen focuses on addressing its underlying cause. Bacterial infections may require antibiotics, whereas viral infections like mononucleosis typically do not respond to such medications.

In severe cases, surgical removal of the spleen (splenectomy) may be recommended. Post-splenectomy, patients can lead healthy lives but should stay vigilant about infection risks and keep up with recommended vaccinations.

Preventing Complications and Maintaining Health

Protecting an enlarged spleen from injury is critical, as rupture can cause life-threatening internal bleeding. Avoid contact sports and always wear a seatbelt while driving to minimize trauma risk.

With timely treatment and lifestyle adjustments, individuals with splenomegaly can enjoy a normal, active life.
