As the saying goes, sickness comes and goes like a mountain. Therefore, it is easy to get sick but hard to get rid of it. Therefore, we must do three parts of treatment and seven parts of maintenance in order to obtain a successful and lasting effect. When I was treating some diabetic patients, I found that those patients who followed my medical advice strictly and cooperated actively with the treatment had good, long-lasting and consolidated results. Those patients who cannot control their mouths, crave for food, and are reluctant to be active and do not know how to control their emotions are prone to fluctuations and recurrence, and have a poor outcome and prognosis. There is a patient who has diabetes for more than 30 years, and also suffers from hypertension, rectal cancer, hyperlipidemia, coronary heart disease, arrhythmia, cardiac insufficiency, and cerebral infarction. I made some suggestions for her situation, and as a result, her blood sugar was well controlled. Last summer, a middle-aged woman was sweating all the time and felt her body was hot in bursts, both during the day and at night when she slept. I prescribed her Chinese medicine for seven days, and the sweating and hot flashes were reduced, which generally should be effective in my experience. Why was it only reduced? Based on my past experience, I judged that there should be something unreasonable in her diet. As a result, I learned that she had been eating walnuts this summer, and not just one or two per day, but a bunch of walnuts, which is considered by Chinese medicine to be homogeneous with food, and some food can also be used as medicine, and walnuts have a warming effect on kidney yang. The doctor thought that the dialectical treatment was wrong. So, the patient listened to me and with my herbal medicine, she soon got well. Finally, she told me that before this, she had already seen a Chinese medicine doctor without effect, but she didn’t expect to be cured again with you, and she understood that the relationship between diet and disease is so important.
