Puffy feet and neck is clinically known as ankle edema, and the causes are mostly related to physiological and pathological factors. Physiological factors are common in women who maintain a posture for a long time and during menstruation and pregnancy, while pathological factors may be caused by nephrogenic edema, heart failure and malnutrition. I. Physiological factors 1. When sitting or standing for a long time, the blood circulation of the whole body is slower, causing delayed venous return of the lower limbs, which will make the feet and neck swollen; 2. Women during menstruation and pregnancy are affected by endocrine secretion in the body, and different degrees of swelling of the feet and neck will occur, which belongs to the physiological regulation of the body. Second, pathological factors 1, nephrogenic edema: nephrogenic edema caused by swollen feet and necks common diseases are various types of nephritis, nephropathy, and hypertension and other diseases caused by renal insufficiency. Nephritis contains acute glomerulonephritis and chronic glomerulonephritis, both of which cause a decrease in water and sodium excretion by the kidneys, resulting in water and sodium retention in the body. In addition, capillary permeability increases in nephritis, and water leaks easily from the capillaries into the tissue interstices, resulting in swollen feet and neck; 2. Heart failure: In heart failure, cardiac output decreases, and the effective circulating blood volume decreases, thus forming a certain degree of venous Stasis of blood, resulting in increased venous pressure, the phenomenon of swollen feet and neck or even swollen body; 3, malnutrition: malnutrition edema is often caused by chronic wasting diseases, such as long-term bedridden and protein loss, blood albumin reduction, may cause swollen feet and neck; 4, other: lower extremity venous thrombosis, foot neck sprain and other conditions may also cause swollen feet and neck. Note: The cause of swollen feet and necks is not unilateral, but may also be signs of certain diseases, should promptly seek medical attention to clarify whether edema suggests the existence of lesions, and then further symptomatic treatment.
