Edema caused by kidney deficiency - Kidney deficiency and water retention syndrome

In addition to the growth, development, and reproductive disorders mentioned above, kidney diseases also cause abnormalities in water metabolism. Because the kidney is the water organ, it opens up to the ears and two orifices, and controls bowel movements, that is, it manages water metabolism and regulates the secretion and excretion of urine and feces. So what are the clinical manifestations of kidney deficiency and water retention?

What is kidney deficiency and water retention syndrome?

Kidney deficiency and water overflow syndrome refers to the deficiency of kidney Yang Qi, inability to transform Qi, and overflow of water. Edema of the lower limbs is particularly common, accompanied by oliguria, chills and cold limbs as the main symptoms of deficiency and cold syndrome. Now let me tell you what kind of edema is the real edema caused by kidney yang deficiency and water vapor overflow.

Clinical manifestations

The main clinical manifestations of kidney deficiency and water retention syndrome are soreness of waist and knees, tinnitus, edema of the body, especially below the waist, subsidence when pressed, short urine volume, chills and cold limbs, abdominal distension, or palpitations, shortness of breath, cough, wheezing and sputum, pale and fat tongue, white and slippery tongue coating, and deep, slow and weak pulse. Edema below the waist combined with some symptoms of kidney yang deficiency is considered edema due to yang deficiency and water retention. Most cases of water flooding due to kidney yang deficiency are caused by long-term illness that damages the yang Qi in the kidney, or by congenital deficiency of the body, resulting in weak yang Qi, inability to transform qi, and inability to transport and transform water and dampness, leading to water flooding.

Key points of syndrome differentiation

The main diagnostic points of kidney deficiency and water retention syndrome include obvious lower limb edema, oliguria, chills and cold limbs.

Kidney Yang is deficient and cannot evaporate and vaporize, so moisture overflows the skin, causing edema. The kidney is located in the lower abdomen, and Yang deficiency cannot transform into vapor, so moisture descends, so edema below the waist is particularly common, with fingers feeling numb when pressed, and urination is short. Water vapor invades the spleen, and the spleen fails to function properly, causing abdominal distension. Water vapor overwhelms the heart and suppresses heart yang, which causes palpitations. Water vapor is cold and invades the lungs, and the lungs fail to descend, causing coughing, wheezing, and phlegm in the throat. Yang deficiency fails to warm the body, so there is fear of cold, cold limbs, soreness of the waist and knees. The tongue is pale and fat, the tongue coating is white and slippery, and the pulse is deep, slow, and weak, which are signs of yang deficiency and water retention.

In clinical practice, the syndrome of water flooding due to kidney deficiency is often confused with some symptoms of the syndrome of kidney yang deficiency. Both are syndromes of deficiency and cold, and both have signs of kidney yang deficiency, but the syndrome of water flooding due to yang deficiency is more characterized by the symptom of water evil flooding (i.e. edema), while the syndrome of kidney yang deficiency is more focused on the decline of organ functions, with the main feature being the progressive weakening of sexual function.
