Yes, stopping drinking alcohol can cause constipation. Alcohol is a diuretic, which means that it can increase urine production and cause dehydration. Chronic alcohol consumption can also lead to damage to the digestive tract, including the intestines, which can result in constipation. When a person stops drinking alcohol, their body may experience changes in digestion, including slowed bowel movements, which can contribute to constipation. It is important to stay hydrated and maintain a healthy diet when quitting alcohol to help alleviate constipation and other withdrawal symptoms.
