The kidneys are the "foundation of innate vitality." If the human body is likened to a tree, the kidneys are its roots. Only when they absorb and transmit sufficient nutrients can the tree flourish with lush branches and leaves. Kidney deficiency may lead to various health issues.However, in reality, people often exaggerate kidney deficiency. Many equate symptoms like excessive sweating, lower back pain, frequent urination, and decreased libido with kidney deficiency. Upon experiencing these symptoms, they blindly self-medicate with kidney-tonifying remedies, delaying proper treatment. Conversely, some conditions related to kidney deficiency go unrecognized.He Qinghu, Vice President of Hunan University of Chinese Medicine, and Lu Fuhua, Director of the Nephrology Department at Guangdong Hospital of Traditional Chinese Medicine, have summarized four types of kidney deficiency that are most easily overlooked, providing detailed explanations and guidance.
Overlooked 1: Women Need Kidney Care Too
Many believe kidney deficiency is a "male-only" condition, but in reality, women are also susceptible due to physiological and pathological factors. The prevalence of kidney deficiency in women is quite high, not lower than in men.
In modern society, the fast pace of life and work often leaves many women chronically stressed and overworked, leading to energy depletion and subsequent kidney deficiency. As the source of beauty and health, kidney deficiency in women not only diminishes their appearance—manifesting as premature hair loss and poor skin—but also face health issues like depression and memory decline. Furthermore, numerous gynecological conditions—including irregular menstruation, thin vaginal discharge, threatened miscarriage, dysmenorrhea, amenorrhea, decreased libido, breast hyperplasia, uterine fibroids, and menopausal syndrome—are linked to kidney fatigue and deficiency. Therefore, women equally require kidney nourishment.
Neglect 2: Shortness of Breath May Indicate Kidney Deficiency
When discussing breathing, most people immediately think of the lungs, but this is not entirely accurate.Shortness of breath or wheezing may also stem from kidney qi deficiency, which fails to receive lung qi. Symptoms include feeling oxygen-deprived and breathless after minimal exertion.
While breathing involves both lungs and kidneys, its root lies in the kidneys. Only with sufficient kidney qi can the body receive adequate air for free respiration. Insufficient kidney qi weakens this reception, impairing breathing. Thus, to alleviate shortness of breath, focus not only on the lungs but also on regulating the kidneys.
Neglect 3: Dawn Diarrhea as a Warning Sign of Kidney Deficiency
Some elderly individuals experience diarrhea around 4-5 a.m., needing to use the restroom shortly after returning to bed, often requiring two or three trips. This condition, most prone to recurrence during seasonal changes, may indicate "dawn diarrhea."
Traditional Chinese medicine attributes dawn diarrhea primarily to kidney yang deficiency and internal cold accumulation. Treatment should focus on warming the kidneys, strengthening the spleen, and consolidating to stop diarrhea. The Four Spirits Pill—formulated with psoralea, nutmeg,Eucommia bark, Schisandra berries, ginger, and jujube. If symptoms like aversion to cold and cold limbs indicate pronounced kidney yang deficiency, add processed ginger and processed aconite root as needed to enhance the formula's warming effect on the kidneys and spleen.
Misconception 4: Children Can Also Experience Kidney Deficiency
Children are often likened to the morning sun, implying their abundant yang energy makes deficiency unlikely. However, this isn't always true. Pregnancies occurring when parents are frail or ill, after alcohol consumption, or at extreme ages (over 50 or under 18) may result in children born with congenital deficiencies.
Expert Tips for Kidney Health
Tip 1: Kidney-Protecting Massage Routine. One method involves simultaneously massaging the Guanyuan point (located three cun below the navel), the Mingmen point (at the waist, opposite the navel), and the Shenshu points on either side (1.5 cun lateral to Mingmen).Before massaging, rub your palms together until warm. Place your left hand on the front and right hand on the back, then rub in a clockwise and counterclockwise direction until warmth is felt. Another method involves rubbing the Yongquan acupoint on the soles of the feet. Cross your hands and rub back and forth until warmth is felt, typically 120 times per session. It's best to do this morning and evening.
Second Method: Dietary Adjustment. Regularly consume dark-colored foods like black sesame seeds, black rice, black beans, and black fungus. Walnuts, chestnuts, goji berries, bone marrow, and pork kidneys are also beneficial. Additionally, since the kidneys govern "willpower," maintain a positive mindset, manage emotions effectively, avoid extreme joy or sorrow, and minimize anger.
Kidney-tonifying foods to support your regimen:
1. Black beans
Rich in trace elements, black beans combat aging and lower blood pressure. Their abundant dietary fiber aids digestion and prevents constipation. With a sweet nature, they promote blood circulation, clear heat and toxins, and nourish the blood.
2. Black Sesame Seeds
Black sesame seeds contain multiple essential amino acids. When combined with vitamins, these amino acids accelerate metabolism. Regular consumption helps prevent anemia and activates brain cells. They also treat dizziness and limb weakness caused by liver and kidney deficiency.
3. Donkey-hide gelatin (Ejiao)
Ejiao promotes lymphocyte transformation in healthy individuals while regulating calcium metabolism to maintain bodily calcium balance. Its blood-nourishing, yin-tonifying, and dryness-relieving properties are well-established.
4. Angelica Root (Danggui)
Containing medicinal compounds like butylidenelactone and nicotinic acid, angelica root improves kidney function and reduces renal damage. It effectively promotes recovery from renal tubular disorders and offers significant protective benefits for the kidneys.
