Stimulants are not typically associated with causing constipation. In fact, stimulants such as amphetamines and methylphenidate are sometimes used to treat constipation as they can increase bowel movements. However, some individuals may experience gastrointestinal side effects while taking stimulants, such as nausea, vomiting, or abdominal discomfort, which could potentially lead to constipation if left untreated. It’s important to talk to your healthcare provider if you are experiencing any gastrointestinal side effects while taking stimulants.
