Frequent sexual intercourse for women may lead to kidney deficiency. For both men and women, excessive intercourse will deplete the kidney energy, which in turn will lead to kidney deficiency. Kidney deficiency can be further categorized into kidney yin deficiency, kidney yang deficiency and kidney qi deficiency. 1. Dizziness, tinnitus, lumbar and knee soreness (a feeling of soreness and weakness in the lumbar and knee areas), heartburn and insomnia, hot flashes (fever sometimes), night sweats (sweating while sleeping) are common in patients with kidney yin deficiency, which can be treated by nourishing yin and tonifying the kidneys. 2. Patients with Kidney-Yang deficiency commonly suffer from soreness and weakness of the waist and knees, unfavorable joints, lack of warmth in the hands and feet, cold limbs, dysmenorrhea visible in women, infertility due to uterine cold, etc. They should be treated by warming and tonifying the Kidney-Yang (warming and replenishing the kidney yang qi). 3. Patients with kidney qi deficiency commonly urinate too often, have frequent urination at night, deafness, tinnitus and shortness of breath, etc. They can be treated by tonifying the kidney and holding qi (treating the kidney’s failure to hold qi by tonifying the kidney). It is recommended that patients should not exert themselves excessively on weekdays, and if the above symptoms occur, they should go to the hospital in time for treatment under the guidance of the doctor’s diagnosis.
