First where is the edema ? Feet or lower legs often is circulatory , this could be of cardiac or vascular (endothelial dysfunction, atherosclerosis, Buerger’s disease, intermittent claudication) origin. Feeling pulses in the ankles (not that you can do that on-line) tells you if they have adequate peripheral circulation. If not consider Gotu Kola, Ginger, Butchers Broom, Cinnamon, Hong Hua, Rosemary, etc. Abdominal edema is more likely due to lfulminent liver disease, although this can cause edema of the legs as well. Here is an overview of causes of edema
Causes
Edema occurs when tiny blood vessels in the body, also known as capillaries, leak fluid. The fluid builds up in nearby tissues. The leak leads to swelling.
Causes of mild cases of edema include:
Sitting or staying in one position for too long.
Eating too much salty food.
Being premenstrual.
Being pregnant.
Edema also can be a side effect of some medicines. These include:
High blood pressure medicines.
Nonsteroidal anti-inflammatory medicines.
Steroid medicines.
Estrogens.
Certain diabetes medicines called thiazolidinediones.
Medicines use to treat nerve pain.
Sometimes edema can be a sign of a more serious condition. Illnesses that can cause edema include:
Congestive heart failure. Congestive heart failure causes one or both of the heart's lower chambers stop pumping blood well. As a result, blood can back up in the legs, ankles and feet, causing edema. With cardiac issues look for creases in the ear lobes, elevated AST, LDH, Troponin,
Congestive heart failure can also cause swelling in the stomach area. This condition also can cause fluid to build up in the lungs. Known as pulmonary edema, this can lead to shortness of breath.
Liver damage. This liver damage from cirrhosis can cause fluid to build up in the stomach area. and in the legs. This fluid buildup in the stomach area is known as ascites.with liver disease look for yellow sclera’s , yellow palms or soles of feet, elevated AST, ALT, GGT, All Phos, total globulin
Kidney disease. Kidney disease can cause fluid and salts in the blood to build up. Edema linked to kidney disease usually occurs in the legs and around the eyes.
Kidney damage. Damage to the tiny, filtering blood vessels in the kidneys can result in nephrotic syndrome. In nephrotic syndrome, decreased levels of protein in the blood can lead to edema. With Kidney damage or disease look for elevated eGFR, creatinine, Uric acid, LDH, AST, BUN, Phosphorus, in TCM tongue diagnosis look for a puffy, red tongue with a deep central vertical crease with horizontal cracks radiating from the central crack
Deep vein thrombosis, also called DVT. Sudden swelling in one leg with pain in the calf muscle can be due to a blood clot in one of the leg veins. DVT requires medical help right away.
Problems with the system in the body that clears extra fluid from tissues. If the body’s lymphatic system is damaged, such as by breast cancer surgery, the lymphatic system might not drain well. I use a combination of Self Heal, Cleavers and Figwort for treating post-surgical lymphedema
Severe, long-term lack of protein. An extreme lack of protein in the diet over time can lead to edema. You see this in starvation, extreme vegan diets (over decades) and alcoholism/drug addiction
Risk factors
The following increases the risk of edema:
Being pregnant.
Taking certain medicines.
Having a long-lasting illness, such as congestive heart failure or liver or kidney disease.
Having surgery that involves a lymph node.
Complications
If left untreated, edema can cause:
Swelling that gets more and more painful.
Problems walking.
Stiffness.
Stretched skin, which can itch.
Increased risk of infection in the swollen area.
Scarring between layers of tissue.
Less blood flow.
Less ability of the of arteries, veins, joints and muscles to stretch.
Increased risk of skin ulcers
