Hot Weather Can Cause Swelling in the Feet and Ankles

For many seniors, hot temperatures may mean puffiness and swelling in the feet and ankles, especially if you spend a lot of time walking or standing. Medical experts say while this type of swelling is more common as we age, it is important to know if it is the result of a more serious condition requiring medical intervention. 

Known as edema, lower leg and foot swelling is typically caused by abnormal fluid buildup that pools in the feet and ankles. Doctors explain edema can be the result a diet high in sodium, drinking alcohol or standing for long periods of time. It is more common in older adults and those overweight. 

Certain medications and medical conditions can cause or exacerbate edema. One in particular is venous insufficiency, a condition in which the veins, which carry blood back to the heart, have a difficult time pushing blood upward against gravity. Chronic venous insufficiency (CVI) can include swelling in the legs or ankles, a tight feeling in the calves or itchy, painful legs, and pain while walking. It can cause brown-colored skin, often near the ankles; varicose veins; and open sores (ulcers) on the legs.

The Harvard Health Publishing reports common medications like antidepressants, steroids, some blood pressure medications, and hormone replacement drugs can cause edema. This is another reason why it is important to let your healthcare providers known as often lowering a medication’s dose will eliminate the swelling. Other causes of edema are blood clots in the leg, infection or injuries. Occasionally heart, kidney or liver failure is the cause.  

To keep blood flowing and to lessen swelling, doctors recommend compression stockings, avoid sitting for long periods of time, and exercise. Other treatments for serious cases include medication, and in a few cases, surgery.
