Hi, my father is 80 ears old and complaining of stomach ache. He has been slightly constipated so last friday took him to doctor, and was told to use miralax. He was not eating how he normally eats, and even after doctor visit he feels better, but has not regained his full appetite. This morning he says his stomach hurts, and his urine looks like it has blood. He is 5ft11in, 220lb., and has had  stroke, and heart attack. Also has pacemaker.
Hi. Thanks for your query. The history of Stroke, Heart attack and Pacemaker indicates that your Father must be taking some medicines for thinning blood. This may be the reason for blood in the urine. Immediately get the coagulation profile done and consult a Doctor to get the other investigations and treatment to be done. The stomach pains can be due to constipation itself. MiraLax should have helped. You can try enema, and if still has pains as he is already not taking anything orally, it is better to get an opinion of a Doctor to see and examine the abdomen. Get the following investigations
