Colonic splenic flexure syndrome is a digestive system disorder in which patients often have symptoms of pain in the left quadrant of the rib cage, which varies in intensity and is paroxysmal, mostly occurring after eating or meals, and the symptoms can be significantly relieved or disappear after defecation or exhaustion. It is recommended to give medication and appropriate hot compresses to relieve the symptoms according to the condition. Common causes of colonic splenic flexure syndrome are due to strong flexion or adhesion of the colon in the splenic flexure area, causing benign narrowing of the intestinal cavity, resulting in gas or fecal accumulation, usually associated with mental factors, improper diet and poor digestion. The diagnosis is usually confirmed by X-rays and barium enemas, which can reveal whether the transverse colon is too long or prolapsed, and whether there is gas accumulation in the splenic flexure. For patients diagnosed with colonic splenic flexure syndrome, treatment should be tailored to the cause. If the disease is triggered by psychological factors, patients can be treated with drugs to relieve liver depression under the guidance of doctors, such as Chai Hu Daxing Liver San and Yi Yao Wan, etc. If the disease is triggered by improper diet, patients can be treated with drugs to regulate qi and relieve pain, such as Si Mo Tang and Mu Xiang Betel Nut Pill, etc. Note Patients with colonic splenic flexure syndrome should actively adjust their mindset in daily life and should not be overly stressed, while developing good bowel habits and keeping their stools smooth. In case of abdominal distension, massage the abdomen clockwise or do hot compresses with hot towels. Exercise properly and ensure a combination of work and rest.
