Hand swelling may be due to blood reflux, allergy, rheumatoid arthritis, hypothyroidism and other reasons.
1. Blood reflux effect: Prolonged compression of the palm of the hand, resulting in blood vessel pressure blockage, venous blood reflux is blocked, so the hand will be bloated. In addition, wrist, arm and other parts of the fracture may also lead to venous return obstruction and hand swelling.
2. Allergy: Hand swelling may also be caused by local allergic reaction after contacting irritating chemicals, seafood, animal dander and other allergens, which may be accompanied by itching, redness, rash and other symptoms.
3. Rheumatoid arthritis: an autoimmune system disorder resulting in chronic inflammatory reaction of synovial membrane, ligaments and other collateral tissues of the joints, probably due to the increase in the exudation of the finger joints and hand swelling.
4. Hypothyroidism: after hypothyroidism, the synthesis and secretion of thyroid hormone decreases, resulting in the accumulation of mucopolysaccharides in the tissues of the body, so the hands will be swollen and distended.
Hand swelling may be related to a variety of factors, it is recommended to consult a doctor for a definitive diagnosis.
