Yes, stopping drinking alcohol can cause stomach problems. Chronic alcohol use can damage the lining of the stomach and intestines, leading to inflammation and irritation, which can cause symptoms such as abdominal pain, bloating, nausea, and vomiting. When alcohol use is stopped suddenly, the body can experience withdrawal symptoms, which can also include stomach problems such as nausea, vomiting, and diarrhea. These symptoms can range from mild to severe and can last for several days or weeks, depending on the severity of the alcohol use disorder. It is important to seek medical attention if you experience severe or prolonged stomach problems after stopping drinking alcohol.
