What Causes Ankle Swelling?

Determining the actual causes of swollen ankles is the first step to find effective treatment. Therefore, common swollen ankle causes are as follows:

• Gout is a painful inflammation of the ankle due to the accumulation of uric acid crystals within the fluid of the ankle. Uric acid is a substance produced during digestion which helps the body in getting rid of the waste materials and toxins. Patients suffering from gout have abnormal uric acid crystals accumulation in their joints which causes swelling and inflammation.
• Ankle arthritis is an another cause for ankle swelling and occurs when the joint between the shin bone (tibia) and ankle bone (talus) wears out. It can be painful and is more common in patients who are overweight, having rheumatoid arthritis or an injury to the ankle joint.
• Infection in the soft tissues surrounding the ankle joint (cellulitis) or in the joint itself (septic joint) is an unusual swollen ankle cause.
• Abnormal blood flow can impair normal blood circulation in the body and cause swelling around the ankles. Blood clotting is a type of vascular obstruction that occurs in the legs and causes swollen ankles and feet. This swelling, if not treated in time, can extend further to the leg.
• Another cause of swollen ankles is peripheral edema, which is a circulation problem that may occur in both legs. It may cause chronic swelling of ankles due to aging, pregnancy, excessive pressure on the leg veins, obesity, varicose veins, etc.
• Our body is well-equipped to maintain the water level it requires and remove the rest. But sometimes this ability of the body fails due to excessive intake of salt and alcohol, less sweating, pregnancy, etc. As a result, the fluid gets collected within the ankle joints which causes ankle swelling.
• Ankle tendonitis is one of the most common causes for ankle swelling which usually occurs in physically active individuals. Any injury to the posterior tibial tendon, a tendon present on the inside part of the ankle, responsible for raising the arch of the foot can cause severe pain and swelling around the ankle.
• Use of laxatives can also be a cause for swollen ankles. Laxatives are purging medications used to induce bowel movements or loosen the stool at the time of constipation.
• A traumatic injury like ankle sprain, broken ankle, or stress fracture can also lead to swelling around the ankle joint.
• In women, menstruation and pregnancy can be the most common causes of swollen ankle, feet or legs. During pregnancy, there can be excessive ankle swelling due to high blood pressure, a sign of pre-eclampsia which needs immediate doctor's attention.

Infections by pathogens, venous insufficiency, insect bite, malnutrition, intake of medications like steroids, estrogens, antidepressants, etc. are some other causes for swollen ankles.
