Causes of swollen legs and feet: Most calf swelling is caused by kidney or heart disease. However, sometimes ascites caused by liver disease, nutritional imbalance caused by protein deficiency, or hormonal abnormalities caused by menopausal disorders can also cause calf swelling. Local lower limb edema is mostly caused by obstruction of the lower limb veins and lymphatic vessels, which causes body fluids to enter the tissue spaces.

If the condition is serious and cannot be cured, you must see a doctor. If you want to take diuretics, you must get a doctor's diagnosis. It is best to avoid using diuretics.

Differential diagnosis of swollen legs and feet: 1. If the swelling starts from the face and then spreads to the whole body, there is a high possibility of kidney disease, but it may also be acute nephritis or kidney disease. 2. If swelling starts from the feet, it may be caused by heart disease, hypoproteinemia, liver cirrhosis, etc. 3. In the later stages of pregnancy, the whole body and feet are prone to edema; if the edema is severe, it may be pregnancy toxemia. If you press the above swelling with your fingers, water will move and form a depression. 4. If the area does not sink when pressed with your hand and is still swollen, it may be caused by hypothyroidism or side effects of medication. 5. The swelling caused by standing for a long time is not an abnormal phenomenon. 6. Sometimes edema may occur even without any disease. It may be caused by bruises and dislocations. In addition, excessive physical burden, second to third degree flat feet, lymphatic vessel abnormalities, long periods of walking or standing, and improper sitting posture can all cause edema: sitting on a high chair with feet not touching the ground; crossing your legs; sitting on a chair that is too low; and shoes that do not fit can also cause edema. Pregnant women and patients with varicose veins are prone to edema. The swelling will go away after you rest. When the weather is hot, swelling will worsen.
