Swollen ankles may be related to localized ankle lesions, heart disease, kidney disease, etc.
1. Local ankle lesions: due to strenuous exercise may cause ankle fractures, local soft tissue injuries, and may also be due to lower extremity venous return obstruction, causing local blood circulation is not smooth, thus swelling. If it is caused by infection, usually local symptoms such as redness, swelling, heat and pain will appear.
2. Heart disease: such as cardiac insufficiency can lead to the blood pumped out by the heart can not return to the heart, resulting in the venous return of the ankle is blocked, thus causing the depression of the ankle edema.
3. Kidney disease: due to the renal filtration dysfunction, a large amount of proteinuria occurs, resulting in hypoproteinemia, and the lower limbs and ankles may appear depressed edema.
It is recommended to consult a doctor in time after the discovery of ankle swelling, after the cause of the disease is clear, targeted treatment, not self-treatment, in order to avoid delaying the condition.
