Final answer:
Edema in the forearm can be caused by various conditions, including allergic reactions, fractures, and damage to blood vessels or lymphatic vessels.
Step-by-step explanation:
Edema in the forearm can be caused by various conditions:
- An allergic reaction can cause capillaries in the hand to leak excess fluid that accumulates in the tissues.
- A fall onto the tip of the elbow, resulting in a distal humerus fracture, can lead to swelling of the surrounding tissues, potentially causing compression of the artery to the forearm.
- Damage to blood vessels and/or lymphatic vessels or a decrease in osmotic pressure in chronic and severe liver disease can cause edema due to loss of water from the blood to the surrounding tissues.
