What causes swelling?

Not Medical advice: Swelling in the body can be caused by tissue growth, accumulation of body fluid, or the abnormal position or movement of tissue.

Feet and ankles may swell in hot weather or after standing or sitting in the same position for long periods. The face and hands may swell due to an allergic reaction. Swelling may also result from an infection or a serious injury.

Antibody production and the destruction of tissues in the body by cells can cause swelling in people with autoimmune diseases. Some medicines change how body fluids circulate, causing swelling. Swelling can occur due to circulation problems linked to diabetes, heart failure, and kidney disease. Liver disease, cirrhosis, obesity, and malnutrition can cause fluid to collect in the abdomen.

Speaking of swelling caused by circulation problems, there are new nonsurgical treatments for varicose veins. Radiofrequency ablation uses heat to collapse diseased veins. Laser ablation closes off varicose veins and chemicals are injected into veins to seal them. About 50% of Americans over the age of 50 suffer from varicose veins.

Swelling can also be caused by the fluctuation of hormone levels within the body. Some women may notice swelling from retaining fluid during their menstrual cycles.
