Swollen feet require a physical examination, laboratory tests, and imaging studies.
1. Physical examination: A detailed and comprehensive examination of the body is needed to help understand the source of the swelling and its characteristics. Particular attention should be paid to the presence of edema in other parts of the body, the acupressure characteristics of the swollen feet, the skin manifestations of the swollen areas, and the changes in the patient’s body weight.
2. Laboratory tests: Commonly used tests include plasma protein and serum protein content measurement, blood routine, urine routine and renal function, blood red blood cell count and hemoglobin content measurement, and calculation of daily intake and excretion of water and sodium.
3. Imaging tests:
(1) Echocardiography: It is used to diagnose cardiac diseases such as right heart failure, and in combination with clinical features, it can identify the specific type of disease causing cardiogenic edema.
(2) Color ultrasound is used to examine lesions in organs such as the liver, kidneys and thyroid gland.
(3) X-ray examination: It is used to examine diseases such as tricuspid valve stenosis and tricuspid valve closure insufficiency, and to determine the degree of correlation with cardiogenic edema.
Patients with edema of the feet need to choose the appropriate means of examination according to the specific condition under the guidance of the doctor.
