Senna granules are a kind of Chinese patent medicine which is commonly used in clinical practice. Its main ingredient is senna, which is a stimulating laxative with strong effect. Although senna granules are effective in treating constipation, they are not recommended for long-term use. Long-term use may lead to dependence, and patients often need to gradually increase the dose of the drug as the use time increases. Constipation may become more serious after stopping the medication, accompanied by abdominal pain, nausea, vomiting and other gastrointestinal symptoms, and in serious cases, gastrointestinal bleeding. Severe constipation can be treated with gastrointestinal stimulants, laxatives and saline enemas as appropriate under the guidance of a doctor, but do not abuse senna granules and other stimulant laxatives on your own. Patients with constipation should increase dietary fiber, drink more water, work and rest regularly, develop the habit of regular bowel movements, and increase physical activity to promote gastrointestinal motility.
