Swelling of the feet area is common, especially among the older population, according to MedlinePlus, a service of the National Institutes of Health. Abnormal buildup of fluid is called peripheral edema. Painless swelling, which can be a result of many factors, can affect not only the feet, but also the legs, thighs and calves.
Varicose Veins
Varicose veins result from an abnormal collection of blood. If an individual suffers from varicose veins, valves in the blood vessels will not function properly, resulting in blood being transferred into the veins. Pooling of the blood causes the veins to enlarge. Varicose veins can cause pains in the legs and also contribute to mild swelling near the ankles and feet, according to MedlinePlus.
Medical Conditions
Heart failure can make the feet swell, as can other medical conditions such as kidney failure and liver failure. Diabetics have a higher risk of ulcers and infection because they are prone to poor circulation, which can result in swelling, according to Health Canada.
Lifestyle
Wearing uncomfortable shoes or tight clothes can lead to swelling in the legs and feet. Also, a long period of standing can result in feet swelling due to poor blood circulation. Being overweight and increased age can also contribute to swelling of the feet.
Medications
Some medications that help treat high blood pressure can contribute to swelling in the feet. Medications that contribute to swelling in the feet include hormones such as estrogen, which can be found in birth control pills, hormone replace therapy; calicum channel blockers like felodipine; and antidepressants, such as tranylcypromine and phenelzine.
