Does a nicotine patch affect ulcers?

Nicotine patches have not been shown to have a direct effect on ulcers.

Ulcers are open sores that can develop on the skin or inside the body, particularly in the stomach or intestines. They are often caused by a combination of factors such as infection, inflammation, and tissue damage. Nicotine, the addictive substance found in cigarettes and other tobacco products, has numerous effects on the body but is not directly linked to the formation or healing of ulcers.
