what makes feet and hands swell
Injury to the hand can cause swelling. Swelling occurs because of excess fluid that collects in the tissues of the body. The most common places for swelling are the hands, feet, arms, legs and ankles, as reported by MayoClinic.com. Many medical conditions, medications and lifestyle activities cause swelling in the extremities.
An insect sting or bite on the feet or hands often causes swelling, itching and pain. The red lump on the skin is a typical allergic reaction to a bite by mosquitoes, spiders, bedbugs, ticks and flies, and from stings by bumblebees, ants, wasps and hornets, as reported by the University of Maryland Medical Center.
During pregnancy, the body produces approximately 50% more blood and body fluids to meet the needs of the developing baby. Swelling is a normal part of pregnancy that is caused by this additional blood and fluid. Normal swelling, which is also called edema, is experienced in the hands, face, legs, ankles, and feet. This extra retention of fluid is needed to soften the body, which enables it to expand as the baby develops. Extra fluid also helps prepare the pelvic joints and tissues to open for delivery.
