Gastroscopy and colonoscopy revealed redness and swelling of the gastric antral mucosa and chronic colitis. Usually, eating stir-fries with too much oil causes diarrhea, as does eating fruit or drinking water below body temperature. When eating hot meals, the back of my head and upper back sweat profusely, and they also sweat with minimal exercise. In the summer, my soles, knees, and stomach are sensitive to wind and cold. I start wearing hats, scarves, and an abdominal warmer in late autumn. I have been treated in Beijing for two years with no effect, and my conditions are increasing.
Answer: First, the diarrhea from eating greasy food is related to colitis and may also be related to poor bile secretion. Many people with gallstones or even liver disease have chronic diarrhea as a symptom. Because bile is secreted by the liver, and the gallbladder only stores it, you should also check if there is a problem with the liver and gallbladder. If not, it can be treated according to Traditional Chinese Medicine (TCM) principles of strengthening the spleen to drain dampness. Given the long duration of your condition and the problem of diarrhea from drinking cold water, there might also be a possibility of kidney yang deficiency in TCM. You can use "Xiang Sha Yang Wan" (香砂养胃丸) along with "Si Shen Wan" (四神丸). The former is for diarrhea caused by greasy food, and the latter is for diarrhea triggered by cold.
All the sweating and aversion to wind are related to qi deficiency. Overall, spleen qi deficiency is the main characteristic of your constitution, so you need to regularly replenish your qi. You can use 10 grams of raw astragalus root to make tea daily. Add 10 grams of schisandra berry and 20 grams of floating wheat at the same time. Astragalus root replenishes qi, while the latter two herbs are for astringing sweat and do not conflict with the two patent medicines mentioned above. This is the daily dose. Steep it in boiling water, let it sit for an hour, and then drink it like tea, refilling with water as needed. Change to a fresh batch with the same dose the next day. You should see an improvement in the sweating symptoms in about three to five days.
It is important to note that you must use raw astragalus root. Raw astragalus has a stronger effect on strengthening the spleen. If you don't specifically instruct the pharmacy, they will usually give you prepared astragalus. Prepared astragalus is better for toning the spleen and stomach, but its effect on replenishing qi is slightly weaker, and it is more likely to cause "heatiness" than raw astragalus.
