Let's talk about the health things of Lichun
In traditional Chinese medicine, blood in the stool is usually considered to belong to the category of "blood syndrome", and its pathogenesis is complex, which can be seen in both empirical and false evidence. In modern medicine, blood in the stool can be a symptom of a variety of diseases, two of the most common of which are hemorrhoids and colon cancer. In this article, we will elaborate on the **, symptoms, diagnosis, and ** of these two diseases from the perspective of Chinese medicine and Western medicine.
1. Hemorrhoids. 
Hemorrhoids are the dilation of the veins of the rectal venous plexus and are a common benign condition. Its ** main points are as follows:
1.Standing or sitting for long periods of time: Holding the same position for long periods of time can increase pressure on the rectum and cause the veins to dilate.
2.Constipation or diarrhea: Constipation or diarrhea can increase the pain during bowel movements, causing the patient to push too hard, which in turn can cause the veins to dilate.
3.Pregnancy: During pregnancy, an enlarged uterus can compress the pelvic veins, causing veins to dilate** and the rectum.
4.Unbalanced diet: Long-term consumption of spicy, greasy foods, or a lack of dietary fiber can lead to constipation, which can lead to hemorrhoids.
The main symptoms of hemorrhoids are:
1.*Pain: Pain during bowel movements, especially when the stool is dry and hard.
2.*Bleeding: Bleeding during bowel movements, blood is usually bright red and drips down the toilet bowl or gets on toilet paper when wiping.
3.Swelling: and dilation of the veins in the rectum, resulting in swelling.
2. Colon cancer.
Colon cancer is a malignancy that originates from the epithelial cells of the colon mucosa,** which is not fully understood, but may be related to:
1.Diet: A diet high in fat, protein, and fiber may increase the risk of colon cancer.
2.Genetic factors: Genetic diseases, such as familial colon polyposis, increase the risk of colon cancer.
3.Inflammatory bowel disease: Chronic inflammatory bowel disease, such as Crohn's disease and ulcerative colitis, may increase the risk of colon cancer.
The main symptoms of colon cancer are:
1.Changes in bowel habits: such as diarrhoea, constipation, or alternating between diarrhoea and constipation.
2.Blood in the stool: Blood in the stool, which is usually dark red and may attach to the surface of the stool.
3.Weight loss: Weight loss for no apparent reason may be an advanced symptom of colon cancer.
3. Diagnosis and **.
1.Diagnosis of hemorrhoids with**:
Diagnosis: The diagnosis of hemorrhoids is based on history and physical examination, and if necessary, a digital examination or anoscopy may be performed.

2) Drugs**: such as Ma Yinglong hemorrhoid ointment, etc., which have the effects of clearing heat and detoxifying, reducing swelling and relieving pain.
3) Surgery**: For patients with severe symptoms and ineffective conservative**, surgery** can be used, such as rubber band ligation, sclerosing agent injection, etc.
2.Diagnosis of colon cancer with **:
Diagnosis: The diagnosis of colon cancer is mainly based on colonoscopy and pathological biopsy.
*:The principle of colon cancer is early detection and early surgical resection, followed by chemotherapy and radiotherapy the treatment options include:
1) Surgery**: For early-stage colon cancer, surgical resection is the preferred method**.
2) Chemotherapy: Postoperative chemotherapy can help kill residual cancer cells and reduce the risk.
3) Radiotherapy: For locally advanced colon cancer, radiotherapy can alleviate symptoms and improve survival.
Fourth, the perspective of traditional Chinese medicine.
Traditional Chinese medicine believes that the pathogenesis of blood in the stool is complex, but it can be generally boiled down to two categories: "hot forced blood travel" and "qi deficiency without intake". **The principle is to clear away heat and detoxify, cool blood and stop bleeding, or invigorate qi and blood, strengthen the spleen and nourish blood.
1.TCM for hemorrhoids**:
Traditional Chinese medicine believes that hemorrhoids are caused by damp heat betting, accumulation**, resulting in poor flow of qi and blood, and damage to the veins. **The principle is to clear away heat and detoxify, cool blood and stop bleeding. Commonly used medications such as:
1) Cool blood rehmannia soup: clear heat and cool blood, nourish yin and reduce fire.
2) Immortal Prescription Life Drink: Clearing heat and detoxifying, reducing swelling and relieving pain.
2.Traditional Chinese Medicine for Colon Cancer**:
