Kidney crystals can drink alcohol in moderation after healing, but you need to try to avoid excessive intake of alcohol components. If there is no need to drink alcohol, it is recommended to quit drinking and do kidney protection in time. Kidney crystals are generally the preexisting manifestation of kidney stone formation, which are localized crystals formed due to the excessive accumulation of crystals in the body. Appropriate alcohol consumption will not directly cause the recurrence of kidney crystals or kidney function damage, so you can drink alcohol appropriately, but it is not recommended to consume too much alcoholic beverages at one time to avoid alcohol poisoning or central nervous system damage. As the intake of large amount of alcohol will affect the body fluid metabolism while causing central nerve damage, which will lead to different degrees of water reabsorption abnormality or fluid circulation disorders in the drinkers. Therefore, if there is no need to drink alcohol after treatment, patients with renal crystals should quit drinking as soon as possible to protect the nervous system as well as the kidney tissues and avoid crystal accumulation or stone formation. After treatment, patients with kidney crystals need to go to the hospital for regular checkups and adjust their diet and drinking habits under the guidance of doctors.
