What causes hand swelling?

Hand swelling is a common symptom that can be caused by various factors. The following are several common conditions:

1. Poor blood circulation: Prolonged maintenance of the same posture, such as sitting or standing for long periods or sleeping in the same position, may lead to impaired local blood circulation, causing hand swelling.

2. Cervical spondylosis: Protrusion of the cervical intervertebral discs may compress nerve roots, resulting in swelling or numbness in one or both hands.

3. Rheumatoid arthritis: This is a chronic inflammatory joint disease that may cause swelling, inflammation, and pain in the finger joints. Hand swelling might be one of its early symptoms.

4. Lymphatic system problems: Blockage of lymphatic vessels or inflammation of lymph nodes may lead to localized or generalized arm swelling. This condition is commonly seen in patients after breast cancer surgery.

5. Heart failure: In heart failure, the heart's ability to pump blood is reduced, which may lead to systemic or localized edema, including swelling of the hands.

6. Renal insufficiency: When kidney function is impaired, imbalances in the body's water and electrolyte levels may occur, potentially leading to generalized edema, including hand swelling.

7. Trauma: Injuries to the hand, such as fractures or sprains, can also cause localized swelling.

If hand swelling is accompanied by pain, changes in skin color, or other symptoms, it is recommended to seek medical attention immediately.
