Swollen legs, medically known as edema, can have a variety of medical causes. Here are some of the most common causes:

• Fluid buildup: This is the most common cause of swollen legs. It can happen when fluid leaks from the blood vessels into the surrounding tissues. This can be caused by a number of factors, including:
  • Congestive heart failure: When the heart is unable to pump blood effectively, fluid can back up in the legs and cause swelling.
  • Kidney disease: When the kidneys are not working properly, they can't remove excess fluid from the body, which can lead to edema.
  • Liver disease: Cirrhosis, a severe form of liver damage, can prevent the liver from making proteins that help keep fluid in the blood vessels. This can lead to edema in the legs and abdomen.
  • Lymphedema: This is a condition that causes fluid to build up in the tissues due to a blockage in the lymphatic system, which is responsible for draining fluid away from the tissues.
  • Pregnancy: Fluid buildup is common during pregnancy, especially in the third trimester.
  • Certain medications: Some medications, such as steroids and some blood pressure medications, can cause edema as a side effect.

• Inflammation: Inflammation can cause swelling in the legs, often accompanied by pain, redness and warmth. This can be caused by a number of conditions, including:
  • Arthritis: Both osteoarthritis and rheumatoid arthritis can cause inflammation in the joints of the legs, which can lead to swelling.
  • Cellulitis: This is a bacterial infection of the skin that can cause redness, swelling and pain.
  • Deep vein thrombosis (DVT): This is a serious condition that occurs when a blood clot forms in a deep vein, usually in the leg. DVT can cause swelling, pain and redness, and if left untreated, can lead to a life-threatening condition called pulmonary embolism.

• Injury: Any type of injury to the legs, such as a sprain, strain or fracture, can cause swelling. The swelling is usually caused by inflammation and the accumulation of fluid in the injured tissues.

It is important to note that this is not an exhaustive list of all the possible causes of swollen legs. If you are experiencing swollen legs, it is important to see a doctor to determine the underlying cause and get appropriate treatment.

Here are some additional tips for managing swollen legs:

• Elevate your legs: When you are sitting or lying down, elevate your legs above the level of your heart. This will help to drain fluid from your legs.
• Wear compression stockings: Compression stockings can help to apply pressure to your legs, which can help to reduce swelling.
• Reduce your salt intake: Eating too much salt can cause your body to retain fluid, which can worsen swelling.
• Exercise regularly: Exercise can help to improve circulation and reduce swelling.
• Maintain a healthy weight: Being overweight or obese can increase your risk of developing edema.
