In recent years, there are more and more patients with low menstrual flow, postmenstrual error or even amenorrhea, and friends often suffer because they cannot find a clear cause. In the theory of traditional Chinese medicine, “The menstrual water, yin blood, is also the main of the two channels of Chong Ren, up for breast milk and down for menstrual water.” When the qi and blood are abundant, the channels are smooth, and the five organs are functioning normally, menstruation can come as scheduled and in regular amounts. If there are factors that lead to the depletion of qi and blood, the disruption of the meridians and the abnormal function of the five organs, it may cause menstrual irregularities. As usual, problems do not arise in a day, and it may take a longer process to change from quantity to quality. Some friends say, “I have had several abortions, but my menstruation has been normal after the abortion and the volume has not been low, and it is only recently that the problem has arisen. Abortion, whether surgical or medication, is a normal physiological process being artificially terminated and disrupted, which will definitely cause some damage to your body, it just may not be evident, and the quantitative process is still in the accumulation stage. When you continue to damage qi and blood, especially consuming yin blood, such as staying up late for a long time, drinking alcohol, frequent sauna or high-temperature yoga, eating spicy and heavy flavors, and sleeping on electric blankets every day, you will secretly lose your yin blood. 80% of the human body is liquid, when you feel dry mouth, eyes, reduce the belt, dry stool, night dreams, pay attention to this is a self-protection instinctive reaction and warning, menstruation may appear less amount, the cycle after the wrong. Some friends say, I love spicy food, my period is not only quite a lot, not after the wrong, but also early and in large amounts! You know, consumption is definitely present, but why your body does not appear to protect itself? In fact, another instinctive reaction has appeared, you just do not realize it. Under normal circumstances, the yin and yang in the human body are in a state of balance. Your daily appetite for spicy food will produce a lot of heat in the body, and this heat will break the normal balance, and the first instinct of human beings is to accelerate the discharge of this heat, early menstruation and high volume is exactly the performance of this heat excretion, the same reason as nosebleeds on fire. But when your yin and blood consumption is no longer enough to drain the heat, it will inevitably turn out to be low volume or amenorrhea. Some of you may ask, then why would eating spicy food also result in low volume? This is actually the difference between using running water to cool down and using water to extinguish a fire. The former flow, the need for a constant source in order to achieve the role of cooling, once the supplement is insufficient, the water will certainly be less and less; the latter extinguish the fire at the same time, but also consumed themselves, if the fire is constantly, that how much water will be consumed. As some people eat spicy will be in the form of diarrhea to drain heat, while some people show dry stools to steam Yin and blood to consume heat, the instinctive reaction of different human bodies is just different. This is why the adjustment of bad habits has been repeatedly emphasized as very important. When you are still continuously consuming Yin and Blood, and constantly adding “oil” and “firewood”, how can you hope that a few Chinese herbs will help you recover? Self-adjustment is more important than medicine. Can nervousness and cold also affect menstruation? Yes, as mentioned in the beginning, normal menstruation requires not only the fullness of qi and blood, but also the smooth flow of the channels. Mental tension, anger, depression, and even anxiety can cause the flow of Qi and blood to be poorly regulated, thus affecting menstruation. Secondly, “warm is through, cold is condensed”, Yin blood needs to flow in order to play a nourishing, moistening role, once stagnant, like the accumulation of dirty puddles on the ground, frozen into the ice, may form nodules, lumps, swellings, not smooth is less, not through is closed, not through and pain. The obvious breast swelling and pain before menstruation, abdominal pain, abdominal cramps, headaches during menstruation, and even nausea, vomiting and diarrhea are all typical manifestations of irregularities in the meridians and reversals of Qi and blood. Many things in the world do not happen for a single reason, but a variety of factors mixed together, constituting a complex and diverse range of symptoms. Poor menstruation is bound to cause a lack of Yin and Blood replenishment; and a lack of Yin and Blood will likewise aggravate the poor circulation. This is the reason why most patients with low menstrual flow have an impatient temper and liver fire, and why postmenstrual error and amenorrhea can cause the body to gain weight. In the former case, the deficiency of Yin and Blood obstructs the flow of Qi and Blood; in the latter case, the unrestrained performance will further affect the metabolic disorder and depression of the whole body. In short, the world is a big and wonderful place, with many wonderful and esoteric things, but friends should explore and understand themselves the most. The human body is the most mysterious creature in the world, can reproduce and evolve to the present, after years of development of human civilization is not a few thousand years can really explore understand and anatomy clear. Pay attention to your own body, pay attention to the different changes and abnormal reactions of the body every day, you will find that the answer to many questions is in your own hands.
