Menopausal sweating is the manifestation of kidney yin deficiency. Besides sweating, there will be hot flashes, insomnia and dreaminess, upset, fever in hands and feet, dry throat, vaginal dryness and dry skin. You can eat more foods that nourish yin and tonify kidney, such as black fungus, medlar, yam, black sesame, mulberry, duck, mushrooms and so on. And you can also eat some Chinese patent medicines such as Kuntai Capsule and Liuwei Dihuang Pill.
This kind of sweating is not the kind that burns fat after exercise. You won't lose weight unless you lose your appetite or increase your exercise.
