Whether patients with acute cholecystitis can drink water mainly depends on the course of the disease. In the early stages of acute cholecystitis, patients may experience digestive symptoms such as nausea, vomiting, and abdominal distension. At this time, they should not drink water; instead, they require fasting and gastrointestinal decompression to better control the condition, especially to prevent the occurrence of intestinal obstruction. After antibiotic treatment and control of the inflammation, once the gastrointestinal function is fully restored, patients can then drink water, but only in small amounts. For patients with acute cholecystitis, if symptoms do not improve after conservative treatment, it may even be necessary to surgically remove the gallbladder to achieve a definitive cure. The primary method is laparoscopic cholecystectomy, which can effectively treat the condition.
