Ankle edema, medically often referred to as ankle swelling, is a common symptom that may be caused by various factors.
1. Physiological factors: Prolonged standing, sitting for extended periods, or during menstruation and pregnancy in women, may lead to delayed venous return in the lower limbs, resulting in swelling.
2. Lymphatic system obstruction: The lymphatic system is responsible for removing excess fluid and waste from the body. When lymph vessels are damaged or blocked, such as after lymph node removal or due to lymphatic inflammation, local lymphatic drainage may be impaired, leading to localized swelling, including in the ankle area.
3. Endocrine disorders
Hypothyroidism (underactive thyroid) slows down metabolism, affecting fluid balance in the body and potentially causing edema. In addition, the use of hormonal medications may also lead to fluid retention, manifesting as swelling.
4. Trauma or surgery: Trauma, sprains, or surgical procedures affecting the ankle or lower limb can cause local tissue injury and inflammatory reactions, resulting in localized edema.
5. Other factors: Malnutrition, venous return disorders, drug-induced edema, and edema of unknown origin may also lead to ankle swelling.
In daily life, patients should also avoid prolonged standing or sitting, and engage in appropriate lower limb activity to promote blood circulation and alleviate swelling symptoms.
