Types of Edema and Their Impact on the Feet

Edema refers to the accumulation of excess fluid in the body’s tissues, leading to swelling. There are several types of edema, each with distinct causes and effects. Idiopathic edema is a condition where swelling occurs without any clear underlying medical cause, often affecting the feet and ankles. Pulmonary edema occurs when fluid builds up in the lungs, but it can also cause swelling in the feet and ankles as the body struggles to manage fluid balance. Lymphoedema, on the other hand, results from a blockage in the lymphatic system, leading to fluid retention and swelling, commonly in the legs and feet. In all cases, edema can cause discomfort, restricted movement, and skin changes in the affected areas. If you have swollen feet or ankles, it is suggested that you are under the care of a podiatrist who can help you manage this condition.

Swollen feet can be a sign of an underlying condition. If you have any concerns, contact one of our podiatrists of Carolina Foot & Ankle Specialists. Our doctors can provide the care you need to keep you pain-free and on your feet.

Swollen feet are a common ailment among pregnant women and people who stand or sit for extended periods. Aging may increase the possibility of swollen feet and patients who are obese often notice when their feet are swelling too. There may be medical reasons why swollen feet occur:

• Phlebitis - A condition that causes the veins to become inflamed and can also cause leg pain.
• Liver disease - This may lead to low blood levels of albumin which is a protein. This can cause fluid in the blood to pass into the tissues and several areas of the body can become swollen.
• Heart failure - When the heart doesn’t pump properly the blood that is normally pumped back to the heart can pool in the veins of the legs causing swollen feet.
• Kidney disease - One of the main functions of the kidneys is releasing excess fluid in the body. This type of condition can make it difficult for the kidneys to function properly, and as a result the feet may become swollen.
• Deep-vein thrombosis (DVT)- This is a serious condition where blood clots form in the veins of the legs. They can block the return of blood from the legs to the heart which may cause the feet to swell. It is important to be treated by a podiatrist if this condition is present.

Swollen feet can also be caused by bone and tendon conditions, including fractures, arthritis, and tendinitis. Additionally, there may be skin and toenail conditions and an infection may cause the feet to swell. Patients who take medicine to treat high blood pressure may be prone to getting swollen feet. 

Many patients elevate their feet to help relieve the swelling and this is generally a temporary remedy. When a podiatrist is consulted the reason behind the swelling can be uncovered and subsequently treated.
