The main reasons for not being able to drink alcohol after a fracture are as follows: 1. Drinking alcohol can cause an increase in inflammatory mediators in the body, and these inflammatory mediators can cause swelling and pain at the fracture site. 2. After drinking alcohol, it may cause the fracture to heal or slow down wound healing, which is not conducive to fracture recovery. 3. After drinking alcohol, the patient may be less alert and not be able to adequately protect the fracture site, such as If the lower limb is fractured, rushing out of bed for weight-bearing activities after drinking alcohol may cause secondary fractures and even produce some new vascular nerve-related injuries. Therefore, in summary, it is not possible to drink alcohol after a fracture.
