My mother has ahltziemers. She lives with me, her daughter. She is bedridden and is in her later stages of the disease. 2 nights a go she was complaining of a stomach pain. I gave her some tums, and she went to sleep. She woke up vomiting. The next day she was okay tell the next night, and again vomitted. She also complained about her stomach. This morning she got sick once again. She has no fever, urination and bowl movements normal. She has sad she was dizzy the second night. should I wait to take her to the doctor and see if it s a virus? She is 86 years old, and I m making plans soon for a nursing facility.
