My husband, age 42 had a cerebellum stroke one month ago. He's been in and out of the hospital ever since because of vomiting. He's been on anti nausea medicines but cannot hold much down. About 3 weeks after the stoke he was readmitted for bleeding on his brain. His first stroke was caused from a clot. He has had severe constipation so we are not sure if the vomiting is coming from the constipation or the remaining blood on his brain. Is vomiting a common side effect after a cerebellum stroke?
