We ask you to wait until a minimum of 3 months after oral treatment for gastric or duodenal ulcers, and all symptoms have settled.
If you have had a partial gastrectomy for surgery, we ask you to wait for 6 months before donating.
If you have had a total gastrectomy you will not be able to donate, as your ability to absorb iron is permanently reduced.
You will not be able to donate blood if you have ulcerative colitis.
